Padaczka skroniowa
Objawy
Padaczka skroniowa (TLE) jest najczęstszą formą padaczki ogniskowej, stanowiącą około 60% przypadków, charakteryzującą się napadami rozpoczynającymi się w płatach skroniowych. Napady dzielą się na świadome (focal aware seizures), z zaburzeniami świadomości (focal impaired awareness seizures) oraz wtórnie uogólnione toniczno-kloniczne (focal to bilateral tonic-clonic seizures). Aura, trwająca od kilku sekund do 2 minut, obejmuje objawy takie jak déjà vu, silne emocje, halucynacje sensoryczne i zaburzenia widzenia, przy zachowanej świadomości. Napady z zaburzeniami świadomości trwają zwykle 30 sekund do 2 minut i manifestują się automatyzmami, dystonią kończyny górnej, afazją oraz objawami autonomicznymi. Napady z bocznej części płata skroniowego częściej ulegają wtórnej generalizacji, natomiast przyśrodkowa TLE (MTLE) cechuje się powolnym narastaniem zaburzeń świadomości i dłuższym czasem trwania napadów. Faza ponapadowa obejmuje dezorientację, afazję, amnezję, zmęczenie i objawy psychiczne, które są bardziej wyraźne niż w innych typach padaczki.

Definicja padaczki skroniowej
Padaczka skroniowa (temporal lobe epilepsy, TLE) to najczęstsza forma padaczki ogniskowej, występująca u około 60% pacjentów z padaczką ogniskową. Jest to przewlekła choroba neurologiczna charakteryzująca się nawracającymi, nieprowokowanymi napadami, które rozpoczynają się w płatach skroniowych mózgu. Płaty skroniowe odpowiadają za przetwarzanie emocji i są ważne dla pamięci krótkotrwałej, dlatego objawy napadów padaczkowych często wpływają na te funkcje123.
Padaczka skroniowa może wynikać z anatomicznego defektu lub blizny w płacie skroniowym, ale przyczyna często pozostaje nieznana. Najczęstszą nieprawidłowością strukturalną związaną z padaczką skroniową jest stwardnienie przyśrodkowej części płata skroniowego (mesial temporal sclerosis, MTS)45.
Rodzaje napadów padaczki skroniowej
W padaczce skroniowej występują napady ogniskowe, które można podzielić na kilka typów67:
- Napady świadome (focal aware seizures) – dawniej nazywane napadami częściowymi prostymi, podczas których pacjent pozostaje świadomy
- Napady z zaburzeniami świadomości (focal impaired awareness seizures) – dawniej nazywane napadami częściowymi złożonymi, w których występuje zaburzenie świadomości
- Napady ogniskowe wtórnie uogólnione (focal to bilateral tonic-clonic seizures) – napady rozpoczynające się w płacie skroniowym, ale rozprzestrzeniające się na obie półkule mózgu
Napady świadome (aura)
Napady świadome, często nazywane aurą, są pierwszą częścią napadu ogniskowego przed utratą świadomości. Aura działa jako ostrzeżenie przed nadchodzącym napadem. Nie wszyscy pacjenci z padaczką skroniową doświadczają aur, a nie wszyscy, którzy ich doświadczają, pamiętają je1011.
Objawy aury mogą obejmować121314:
- Uczucie déjà vu (poczucie, że aktualna sytuacja już wcześniej miała miejsce) lub jamais vu (poczucie, że znana sytuacja jest nowa)
- Nagłe silne emocje, takie jak strach, panika, lęk, radość, smutek lub gniew
- Rosnące nieprzyjemne uczucie w żołądku, podobne do uczucia podczas jazdy kolejką górską
- Niezwykłe zapachy, smaki lub dźwięki (halucynacje węchowe, smakowe, słuchowe)
- Wzmocnione zmysły (słuch, wzrok, węch, smak lub dotyk)
- Zaburzenia widzenia
- Uczucie nierealności lub bycia poza własnym ciałem
Aury zwykle trwają od kilku sekund do dwóch minut. Pacjent jest przytomny i świadomy podczas tych objawów17.
Napady z zaburzeniami świadomości
Napady z zaburzeniami świadomości (focal impaired awareness seizures) charakteryzują się zatrzymaniem zachowania i zaburzeniem świadomości. W niektórych przypadkach napady świadome (aury) mogą przekształcić się w napady z zaburzeniami świadomości1819.
Objawy napadów z zaburzeniami świadomości obejmują202122:
- Brak świadomości otoczenia i nieodpowiadanie na bodźce
- Wpatrywanie się w przestrzeń
- Rozszerzone źrenice
- Automatyzmy (powtarzające się bezcelowe ruchy), takie jak:
- Ruchy ust (mlaskanie, żucie, przełykanie)
- Ruchy rąk (dłubanie, skubanie ubrań, pocieranie)
- Nadmierne mruganie
- Znieruchomienie (tzw. bezruch behawioralny)
- Dystonia kończyny górnej (zwykle po stronie przeciwnej do ogniska napadowego)
- Zaburzenia mowy lub rozumienia języka (afazja)
- Zaczerwienienie, bladość, tachykardia lub inne objawy autonomiczne
Napady z zaburzeniami świadomości zwykle trwają od 30 sekund do 2 minut2627.
Napady wtórnie uogólnione
W niektórych przypadkach napady skroniowe mogą przekształcić się w napady uogólnione toniczno-kloniczne (focal to bilateral tonic-clonic seizures), zwane dawniej napadami grand mal. Ten typ napadu powoduje drgawki całego ciała i utratę przytomności282930.
Napady wtórnie uogólnione są częstsze w przypadku napadów pochodzących z bocznej części płata skroniowego niż z części przyśrodkowej31.
Objawy i przebieg napadów padaczki skroniowej
Przebieg napadów padaczkowych w padaczce skroniowej można podzielić na trzy fazy3233:
Faza prodromalna
U niektórych pacjentów występują objawy prodromalne na długo przed napadem (godziny lub nawet dni). Mogą one obejmować3435:
- Zmiany nastroju
- Lęk
- Uczucie oszołomienia
- Trudności z zasypianiem
- Trudności z koncentracją
- Zmiany zachowania
- Drażliwość
- Depresja
- Ból głowy
- Euforia
- Splątanie
Faza iktalna
Faza iktalna to właściwy napad padaczkowy. Jak opisano wcześniej, może on przebiegać jako napad świadomy (aura), napad z zaburzeniami świadomości lub napad wtórnie uogólniony36.
W zależności od tego, która część płata skroniowego jest dotknięta (przyśrodkowa czy boczna), napady mogą mieć różne objawy3738:
- Napady z przyśrodkowej części płata skroniowego (MTLE):
- Charakterystyczne objawy na początku napadu, takie jak uczucie unoszenia się w żołądku lub dyskomfort brzuszny
- Objawy poznawcze, jak déjà vu/jamais vu
- Emocjonalne napady z uczuciem strachu
- Nieprzyjemne doznania węchowe i smakowe
- Powolne narastanie zaburzeń świadomości
- Automatyzmy ust i rąk
- Rzadziej ewoluują do napadów toniczno-klonicznych
- Trwają dłużej niż napady z bocznej części płata skroniowego
- Napady z bocznej części płata skroniowego:
- Mogą zaczynać się od objawów słuchowych (brzęczenie, dzwonienie) lub zawrotów głowy
- Krótszy czas trwania
- Wcześniejsze wystąpienie zaburzeń świadomości
- Częściej występują objawy ruchowe, takie jak dystonia kończyny górnej przeciwstronnej lub skręt głowy i oczu
- Częściej przechodzą w napady toniczno-kloniczne
Faza ponapadowa
Po napadzie padaczkowym występuje faza ponapadowa (postictal), w czasie której pacjent może doświadczać szeregu objawów404142:
- Splątanie i dezorientacja
- Trudności z mówieniem (afazja ponapadowa, szczególnie gdy napad dotyczył dominującej półkuli)
- Niemożność przypomnienia sobie napadu (amnezja)
- Nieświadomość, że napad miał miejsce
- Skrajne zmęczenie i senność
- Ból głowy
- Ból mięśni
- Depresja, lęk lub inne objawy psychiczne
- Trudności z koncentracją i przetwarzaniem informacji
Faza ponapadowa w padaczce skroniowej jest zwykle bardziej wyraźna niż w innych typach padaczki, co może pomóc w diagnostyce różnicowej45.
Szczególne cechy napadów w zależności od lateralizacji
Określone cechy napadów mogą sugerować początek napadu w dominującej lub niedominującej półkuli mózgu46:
- Napady z niedominującej półkuli (zwykle prawej):
- Mowa podczas napadu
- Plucie, wymioty
- Picie
- Potrzeba oddania moczu
- Automatyzmy z zachowaniem świadomości
- Napady z dominującej półkuli (zwykle lewej):
- Ponapadowe zaburzenia mowy
Dystonia kończyny górnej jest użyteczną cechą lateralizującą napad do przeciwnej półkuli. Z kolei automatyzmy ręczne zwykle występują po stronie ipsilateralnej (tej samej) co ognisko padaczkowe49.
Progresja padaczki skroniowej i powikłania długoterminowe
Padaczka skroniowa może prowadzić do szeregu długoterminowych komplikacji, szczególnie jeśli napady nie są odpowiednio kontrolowane5051:
Zmiany strukturalne w mózgu
Z czasem powtarzające się napady padaczkowe w płacie skroniowym mogą powodować zmniejszenie wielkości części mózgu zaangażowanej w uczenie się i pamięć, zwanej hipokampem. Utrata komórek mózgowych w hipokampie może prowadzić do problemów z pamięcią525354.
Zaburzenia neurokognitywne
Istnieje ryzyko nieodwracalnego pogorszenia funkcji poznawczych w padaczce skroniowej. Pogorszenie neurokognitywne oznacza, że uczenie się, zapamiętywanie, podejmowanie decyzji lub koncentracja stają się trudniejsze55.
Głównym zaburzeniem poznawczym w przyśrodkowej padaczce skroniowej jest postępujące upośledzenie pamięci. Obejmuje ono upośledzenie pamięci deklaratywnej, w tym pamięci epizodycznej i semantycznej, i jest gorsze, gdy leki nie kontrolują napadów56.
Padaczka skroniowa przyśrodkowa wywodząca się z półkuli dominującej językowo upośledza pamięć werbalną, a padaczka skroniowa przyśrodkowa wywodząca się z półkuli niedominującej językowo upośledza pamięć niewerbalną5758.
Zaburzenia psychiczne
Zaburzenia psychiczne są częstsze wśród osób z padaczką, a najwyższa częstość występuje wśród osób z padaczką skroniową59.
Najczęstsze współistniejące zaburzenia psychiczne to6061:
- Zaburzenia depresyjne
- Zaburzenia lękowe
- Zespół stresu pourazowego
- Zaburzenia obsesyjno-kompulsywne
- Psychozy
- Schizofrenia
- Zaburzenia afektywne dwubiegunowe
- Zaburzenia związane z używaniem substancji psychoaktywnych
Ryzyko samobójstwa jest wyższe wśród osób z padaczką skroniową, z szacowaną częstością około 9%62.
Nagła niewyjaśniona śmierć w padaczce
Osoby z padaczką skroniową mają zwiększone ryzyko nagłej nieoczekiwanej śmierci w padaczce (SUDEP). SUDEP jest rzadkim powikłaniem, a leczenie padaczki może zmniejszyć to ryzyko636465.
Stan padaczkowy
W rzadkich przypadkach napad padaczkowy może trwać długo lub może wystąpić kilka napadów bez odzyskania świadomości pomiędzy nimi. Stan ten nazywany jest stanem padaczkowym (status epilepticus) i wymaga pilnego leczenia, aby zapobiec uszkodzeniu mózgu6667.
Objawy padaczki skroniowej w różnych grupach wiekowych
Niemowlęta i dzieci
U niemowląt napady skroniowe mogą być subtelne i manifestować się bladością, bezdechem i zatrzymaniem zachowania. Mogą występować wcześniejsze i bardziej wyraźne manifestacje ruchowe, w tym napady toniczne i spazmy padaczkowe, co może odzwierciedlać różne wzorce rozprzestrzeniania się w rozwijającym się mózgu68.
U dzieci z padaczką skroniową mogą występować aury, czyli napady świadome, które mogą obejmować uczucie déjà vu, doznania zapachowe, smakowe, dźwiękowe lub wizualne, emocje (takie jak strach) i nudności lub uczucie unoszenia się w brzuchu69.
Dzieci z napadami z zaburzeniami świadomości mogą wpatrywać się, pocierać ręce lub mlaskać ustami. Podczas napadu może być trudno mówić lub rozumieć język. Czasami napad ogniskowy może rozwinąć się w napad toniczno-kloniczny, w którym całe ciało drga70.
Dorośli
U dorosłych padaczka skroniowa zwykle zaczyna się w późnym okresie nastoletnim lub wczesnej dorosłości, chociaż może również rozpocząć się we wcześniejszym okresie dojrzewania lub później w dorosłości71.
Objawy u dorosłych są podobne do tych opisanych wcześniej, z napadami świadomymi (aura), napadami z zaburzeniami świadomości i możliwymi napadami wtórnie uogólnionymi72.
Dorośli z padaczką skroniową często zgłaszają problemy z pamięcią, szczególnie pamięcią deklaratywną, oraz trudności z uczeniem się nowych informacji73.
Przebieg choroby i rokowanie
Padaczka skroniowa jest jedną z najbardziej opornych na leki form padaczki. Około 75% pacjentów z przyśrodkową padaczką skroniową nie osiąga znaczącej kontroli napadów przy pomocy samego leczenia farmakologicznego74.
Z drugiej strony, interwencja chirurgiczna może być skuteczna, z około 70-80% pacjentów osiągających stan wolny od napadów po operacji płata skroniowego7576.
Obecność stanu wolnego od napadów 2 lata po przedniej lobektomii skroniowej jest predyktorem długoterminowego wyniku bez napadów dla pacjenta77.
Dla wielu osób padaczka skroniowa może być skutecznie leczona lekami lub operacją, pozwalając na prowadzenie normalnego życia. U dzieci z padaczką skroniową napady mogą nawet ustąpić z czasem78.
Osoby, które mają trudności z kontrolowaniem napadów, mogą również doświadczać problemów z nastrojem lub pamięcią, co prowadzi do obniżonej jakości życia i zwiększonego ryzyka śmierci79.
Przy odpowiednim leczeniu farmakologicznym i dostosowaniach stylu życia, osoby z napadami padaczkowymi mogą prowadzić pełne życie80.
Różnice między padaczką skroniową a innymi typami napadów
Napady padaczki skroniowej mogą przypominać inne typy napadów, ale mają pewne charakterystyczne cechy, które pomagają w diagnostyce różnicowej81:
Padaczka skroniowa vs. padaczka czołowa
Napady z zaburzeniami świadomości pochodzenia skroniowego mogą mieć podobne cechy do napadów z zaburzeniami świadomości pochodzenia czołowego, jednak napady pochodzenia skroniowego zwykle mają wolniejszy początek i progresję, a ponapadowa dezorientacja jest bardziej wyraźna82.
Padaczka skroniowa vs. napady nieświadomości
Napady z zaburzeniami świadomości pochodzenia skroniowego muszą być odróżniane od napadów nieświadomości. Chociaż oba typy mogą mieć automatyzmy, napady skroniowe są zwykle dłuższe (≥30 sekund), związane z bladością i następuje po nich ponapadowa dezorientacja83.
W przeciwieństwie do napadów nieświadomości, które nie są związane z ponapadową dezorientacją, pacjenci z padaczką skroniową zwykle doświadczają fazy ponapadowej charakteryzującej się dezorientacją84.
Podsumowanie
Padaczka skroniowa jest najczęstszą formą padaczki ogniskowej, charakteryzującą się napadami rozpoczynającymi się w płatach skroniowych mózgu. Objawy są różnorodne i mogą obejmować aury (napady świadome) z uczuciem déjà vu, strachem lub doznaniami żołądkowymi, napady z zaburzeniami świadomości z automatyzmami ust i rąk, oraz możliwe napady wtórnie uogólnione.
Przebieg choroby może prowadzić do zmian strukturalnych w mózgu, zaburzeń neurokognitywnych, problemów psychicznych i innych powikłań, szczególnie jeśli napady nie są odpowiednio kontrolowane. Wczesne rozpoznanie i leczenie są kluczowe dla kontroli napadów i zapobiegania długoterminowym powikłaniom.
Mimo że padaczka skroniowa może być oporna na leki, wielu pacjentów osiąga dobrą kontrolę napadów dzięki leczeniu farmakologicznemu lub chirurgicznemu, co pozwala im prowadzić normalne życie z minimalnym wpływem choroby.

In addition to neurological features, TLE is frequently associated with psychiatric comorbidity. The prevalence of psychiatric disorders in patients with TLE is higher than in generalized epilepsy particularly in the pediatric population (79 vs. 47%). Anxiety, depression, and interictal dysphoria often combined with cognitive, learning, and behavioral impairment are recurrent psychiatric disorders in the pediatric patients with TLE. […] Mesial temporal sclerosis (MTS) is the most common structural abnormality associated with TLE. MTS is correlated to a higher prevalence of psychiatric symptoms up to 70% in pharmacoresistant forms of TLE. […] Cognitive and behavioral disorders occur in almost 50% of patients with dysphoric symptoms and usually begin within 2472 h postictally. […] Psychiatric symptoms can occur before and after seizure.

The most common brain region for focal seizures to arise is one of the temporal lobes, of which there are two one on either side of the brain. These lobes serve many functions and are involved in vocal, auditory and visual processing, as well as emotions and memory. This is why seizures arising from these areas can lead to a variety of unusual symptoms. […] Frequently, focal temporal lobe seizures are relatively subtle, particularly to witnesses. Sometimes they are comprised of purely unusual internal sensations such as sudden intense fear, a sudden sense of dj vu or possibly a strong odor. Until a seizure spreads to involve more areas of the brain, it may not cause loss of consciousness or convulsions. […] Because untreated seizures become more frequent and severe over time, it is not uncommon for epilepsy to begin with these relatively subtle focal seizures, then worsen as the seizures begin to involve more brain tissue, and eventually progress to convulsions.
- #8 Temporal Lobe Epilepsy: Causes, Symptoms, and Treatmenthttps://www.healthline.com/health/temporal-lobe-epilepsy
Temporal lobe epileptic seizures are further classified. If there is a loss of consciousness, theyre called complex partial seizures. If you stay conscious, theyre called simple partial seizures. In most cases, people remain conscious during temporal lobe seizures, making them simple partial seizures. […] When a temporal lobe seizure starts to occur, a person may experience sudden, unusual feelings, such as: deja vu, extreme happiness, a rising sensation in the abdomen, anxiety. These early signs are called auras or warnings, and they may last for a few seconds up to a few minutes before the seizure occurs. Other possible auras include hallucinations of sounds, voices, people, smells, and tastes. Not all people who experience temporal lobe seizures experience auras. Sometimes people do not remember experiencing an aura.
- #9 Temporal Lobe Epilepsy | The Defeating Epilepsy Foundationhttps://www.defeatingepilepsy.org/understanding-epilepsy/temporal-lobe-epilepsy/
An indication of an oncoming focal seizure is unusual sensations called auras. Auras can instigate strong emotions, changes in vision, dj vu, and auditory hallucinations. However, memories of these experiences often vary between patients. A common sensation is a rising feeling in the abdomen similar to the effects of riding a roller coaster. The reaction of a focal seizure may result in impaired responsiveness which can be indicated by staring into space and a lack of response. Motor effects may be impacted by displaying repetitive actions such as lip-smacking and unusual motions in the fingers. The seizure may last a few seconds to 2 minutes. Following the seizure, patients often experience difficulty communicating, inability to recall the seizure, and extreme fatigue. […] Two types of focal seizures could occur, focal aware seizures or focal impaired awareness seizures. Focal aware seizures are when there is no change of consciousness during the seizure, formerly known as simple partial seizures without loss of awareness. The occurrence of this seizure could last from a few seconds to 2 minutes experiencing abnormal sensations, dj vu, a sudden change in emotion, altered senses, and visual distortion. Focal impaired awareness seizures affect the level of consciousness to some degree lasting from 30 seconds to 2 minutes, formerly known as complex partial seizures with loss of awareness. The seizure can start in a localized area but often spreads. It is common for those to have an aura before a seizure resulting in staring, automatisms, confusion, unusual speech, and loss of the ability to communicate. A person cannot interact with the surrounding environment as they typically would.

Temporal lobe epilepsy symptoms can include an epileptic aura (an unusual sensation you feel before a seizure) and the seizure itself. […] Symptoms of epileptic auras may include: Dj vu (a feeling of familiarity), a memory or jamais vu (a feeling of unfamiliarity); a sudden sense of fear, panic or anxiety; anger, sadness or joy; a rising sick feeling in your stomach (like the feeling you get in your gut when riding a roller coaster); stronger senses (hearing, sight, smell, taste or touch). […] Not everyone experiences an aura. An aura is also described as a focal-aware seizure, meaning you’re awake and aware while the symptoms occur. They typically last from a few seconds to two minutes. […] Other seizure symptoms can follow the aura. You may experience signs and symptoms including: loss of consciousness; a blank stare; dilated pupils; repetitive non-purposeful behaviors and movements (automatisms) of your hands (fidgeting, picking motions), eyes (excessive blinking) and mouth (lip-smacking, chewing, swallowing); confusion; brief loss of ability to speak or understand language (aphasia); stiffening and jerking of your body.
- #13 Focal seizures – Epilepsy Actionhttps://www.epilepsy.org.uk/info/seizures/focal-seizures
If you have been diagnosed with temporal lobe epilepsy it means you have seizures starting in one or other of the temporal lobes. The temporal lobe is responsible for things like memory, hearing and understanding language. […] Seizures starting in the temporal lobes are usually, but not always, focal impaired awareness seizures. You might start the seizure being aware of whats happening, and then lose awareness as the seizures goes on. […] Symptoms of seizures in the temporal lobes include: Feeling frightened, Feeling like whats happening has happened before (deja vu), Hearing things that arent there, Experiencing an unpleasant taste or smell, Having a rising sensation in your stomach, Lip smacking, repeated swallowing or chewing, Changes to your skin tone or heart rate, Automatic behaviours such as fidgeting, undressing, running or walking. […] After a temporal lobe seizure you are likely to be confused or may find it hard to speak for a short time.
- #14 Psychomotor Seizure (aka Complex Partial Seizure)https://www.healthline.com/health/epilepsy/psychomotor-seizure
Psychomotor seizure is an older term used to describe a seizure that begins in your brains temporal lobe. You might experience unusual sensations, loss of consciousness, and convulsions. […] Temporal lobe seizures may affect these functions of your brain and create odd feelings, like dj -vu or strong emotions. […] A temporal lobe seizure can begin with an unusual sensation, also known as an aura. An aura typically lasts a few seconds to minutes. […] During an aura, you may experience: a feeling of dj vu, sudden, unprovoked, extreme emotions like panic or excitement, a strange odor or taste, a sudden bout of nausea, a sinking feeling in your stomach, similar to what you may experience when you plunge down a roller coaster. […] Following (or instead of) an aura, some people experience a focal impaired awareness seizure. This type of temporal lobe seizure affects your consciousness or ability to respond to others. During this type of seizure, you may: loss of awareness of your surroundings, experience staring spells, smack your lips, swallow, or chew repeatedly, perform unusual finger movements, such as picking.
- #15 Temporal Lobe Epilepsy | The Defeating Epilepsy Foundationhttps://www.defeatingepilepsy.org/understanding-epilepsy/temporal-lobe-epilepsy/
An indication of an oncoming focal seizure is unusual sensations called auras. Auras can instigate strong emotions, changes in vision, dj vu, and auditory hallucinations. However, memories of these experiences often vary between patients. A common sensation is a rising feeling in the abdomen similar to the effects of riding a roller coaster. The reaction of a focal seizure may result in impaired responsiveness which can be indicated by staring into space and a lack of response. Motor effects may be impacted by displaying repetitive actions such as lip-smacking and unusual motions in the fingers. The seizure may last a few seconds to 2 minutes. Following the seizure, patients often experience difficulty communicating, inability to recall the seizure, and extreme fatigue. […] Two types of focal seizures could occur, focal aware seizures or focal impaired awareness seizures. Focal aware seizures are when there is no change of consciousness during the seizure, formerly known as simple partial seizures without loss of awareness. The occurrence of this seizure could last from a few seconds to 2 minutes experiencing abnormal sensations, dj vu, a sudden change in emotion, altered senses, and visual distortion. Focal impaired awareness seizures affect the level of consciousness to some degree lasting from 30 seconds to 2 minutes, formerly known as complex partial seizures with loss of awareness. The seizure can start in a localized area but often spreads. It is common for those to have an aura before a seizure resulting in staring, automatisms, confusion, unusual speech, and loss of the ability to communicate. A person cannot interact with the surrounding environment as they typically would.
- #16 Temporal lobe epilepsieshttps://www.aboutkidshealth.ca/temporal-lobe-epilepsies
Temporal lobe epilepsy involves seizures that can produce a variety of sensations such as abdominal pain, fear or a sense of dj vu or jamais vu. […] Typical features may include auras (focal aware seizures), repetitive non-purposeful movements (automatisms), such as chewing, swallowing or picking at clothes and confusion or difficulty speaking after the seizure. […] Temporal lobe epilepsy usually manifests with either focal seizures with or without awareness impairment arising from the temporal lobe. […] Because the temporal lobe is involved with emotions and memory, these seizures often produce emotions such as fear, joy or anger, or memory phenomena such as dj vu (a feeling of having seen something before, even though it is new to you) or jamais vu (a feeling that you have never seen a familiar object or place before).
- #17 Temporal Lobe Epilepsy (TLE): Causes, Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/17778-temporal-lobe-seizures
Temporal lobe epilepsy symptoms can include an epileptic aura (an unusual sensation you feel before a seizure) and the seizure itself. […] Symptoms of epileptic auras may include: Dj vu (a feeling of familiarity), a memory or jamais vu (a feeling of unfamiliarity); a sudden sense of fear, panic or anxiety; anger, sadness or joy; a rising sick feeling in your stomach (like the feeling you get in your gut when riding a roller coaster); stronger senses (hearing, sight, smell, taste or touch). […] Not everyone experiences an aura. An aura is also described as a focal-aware seizure, meaning you’re awake and aware while the symptoms occur. They typically last from a few seconds to two minutes. […] Other seizure symptoms can follow the aura. You may experience signs and symptoms including: loss of consciousness; a blank stare; dilated pupils; repetitive non-purposeful behaviors and movements (automatisms) of your hands (fidgeting, picking motions), eyes (excessive blinking) and mouth (lip-smacking, chewing, swallowing); confusion; brief loss of ability to speak or understand language (aphasia); stiffening and jerking of your body.
- #18 TEMPORAL LOBE SEIZUREhttps://www.epilepsydiagnosis.org/seizure/temporal-overview.html
Temporal lobe seizures are characterized by behavioral arrest and impaired awareness. Automatisms are common during the seizure, and include oral and/or manual automatisms. There may sensory (auditory), emotional (fear), cognitive (deja vu) or autonomic features (epigastric sensation, tachycardia, colour change) prior to onset of impaired awareness. Postictal confusion typically occurs. […] Specific features suggest seizure onset in the dominant or non-dominant temporal lobe (see hemispheric lateralization). Ictal speech, spitting, vomiting, drinking, urge to urinate and automatisms with preserved consciousness suggest seizure onset in the non-dominant temporal lobe. Postictal speech disturbance suggests a dominant temporal lobe seizure. Upper limb dystonia is a useful lateralizing feature, lateralizing the seizure to the contralateral hemisphere. Conversely, manual automatisms usually occur on the ipsilateral side.

Seizures that arise in the mesial temporal lobe may be characterized by distinctive seizure onset features such as an autonomic seizure with rising epigastric sensation or abdominal discomfort, or cognitive seizure with deja vu/jamais vu, or emotional seizure with fear. Unpleasant olfactory and gustatory sensory seizures may also occur. These focal seizure types may occur in isolation or may be followed by the onset of behavioral arrest with slowly progressive impairment of awareness and oral (chewing, lip-smacking, swallowing, tongue movements) and manual automatisms. Autonomic phenomena (pallor, flushing, tachycardia) are common. Upper limb automatisms may be unilateral and may lateralize the seizure to the ipsilateral hemisphere. Unilateral pupillary dilatation can occur, and can also lateralize the seizure to the ipsilateral hemisphere. Contralateral upper limb dystonia may develop and head and eye version to the contralateral side can occur. Whilst seizures tend to have a longer duration than for lateral temporal lobe seizures, evolution to a focal to bilateral tonic-clonic seizure is uncommon.

Symptoms of a focal impaired awareness seizure include: blank staring expression, repetitive movements like lip-smacking, blinking, grunting, shouting, or gulping, repetitive hand movements, confusion, nonsensical speech or an inability to communicate. […] A focal impaired awareness seizure may spread into both sides of the brain and cause a tonic-clonic seizure. During a tonic-clonic seizure, you will lose consciousness and your body will become stiff and convulse. […] After the seizure is over, you may feel sleepy and require time for rest. […] Symptoms during temporal lobe seizures can include unusual stomach sensations, emotional changes, a feeling of déjà vu, and more.

Epilepsy is a chronic neurological condition that causes episodes of abnormal electrical activity in the brain, resulting in seizures. Temporal lobe epilepsy (TLE) seizures begin in the temporal lobe and often involve unusual feelings, movements, or behaviors. […] During a TLE seizure, a person may remain conscious or lose consciousness. […] The symptoms of TLE seizures relate to a persons awareness during a seizure. These classifications include focal onset aware seizures and focal impaired awareness seizures. […] During a focal onset aware seizure, a person remains alert. These types of seizures often include strange feelings or sensations known as auras. […] After a temporal lobe seizure, a person may experience confusion and speech difficulties or feel extremely weak or sleepy. They may also be unable to remember the seizure. […] During a TLE seizure, a person may remain alert and experience auras. Alternatively, they may lose awareness and the ability to understand language.
- #31 TEMPORAL LOBE SEIZUREhttps://www.epilepsydiagnosis.org/seizure/temporal-overview.html
Lateral temporal lobe seizures may have an initial focal seizure with auditory or vertiginous features. The focal sensory auditory seizure is usually a basic sound such as buzzing or ringing (rather than formed speech). If the sound is heard in only one ear it suggests the seizure is in the contralateral hemisphere. In comparison to mesial temporal lobe seizures, lateral temporal seizures are of shorter duration, and the onset of impaired awareness is an earlier feature (the initial aware phase is not as prolonged). Lateral temporal lobe seizures may spread and motor features such as contralateral upper limb dystonia, facial twitching or grimacing, and head and eye version may occur. Evolution to a focal to bilateral tonic-clonic seizure is more common than in mesial temporal lobe seizures.

Not all people experience this stage. Some common signs can include: Mood changes, Anxiety, Feeling lightheaded, Difficulty sleeping, Difficulty staying focused, Behaviour changes. […] Auras are generally considered an early part of the seizure. Symptoms of an aura may include: Déjà vu (a sense that something has happened before when in fact it hasnât), Jamais vu (a feeling that youâre seeing something you know well for the first time), Odd smells, sounds or tastes, Dizziness, Vision difficulties, Numbness or âpins and needlesâ in parts of the body, Nausea, Headache, Panic, Feelings of intense fear. […] The middle (ictal) stage of a seizure is called the ictal phase. Itâs the time from the first symptom to the end of the seizure activity. It is during this time that intense electrical activity is occurring in the brain. Some common signs of this phase include: Loss of awareness, Memory lapse, Feeling confused, Difficulty hearing, Odd smells, sounds or tastes, Difficulty speaking or saying strange words, Twitching, Loss of muscle control, Repeated movements (such as lip smacking or chewing), Body convulsions, Racing heart, Trouble breathing.

[…] Signs and symptoms vary between individuals and depend on many factors, including age, type and severity of the seizure, and underlying brain function. […] As mentioned, 96% of people with epilepsy report being less responsive after a seizure. […] If the left temporal lobe is affected, you might experience problems with language, e.g., listening, comprehension, and speaking.

Patients can recall the initial phase but have little or no recollection of the period of reduced consciousness. The postictal phase is usually marked by confusion. Ictal and postictal dysphasia are common when the seizure focus is in the language-dominant temporal lobe. Occasionally, focal seizures may develop into a tonic-clonic seizure. […] The initial symptoms of the seizure depend on which temporal lobe is affected, the location and function of the seizure network and the seizure propagation pattern. Initial symptoms may be autonomic, cognitive, emotional, or sensory. […] Many patients, especially those with hippocampal sclerosis, have cognitive difficulties in addition to seizures. If the sclerosis is localised to the language-dominant hemisphere, difficulties with memory for language are often seen. Many people struggle to remember information related to time and place. If the sclerosis is localised to the non-dominant hemisphere, patients may have difficulties with visual memory, for example remembering faces or places they have been.

In infants, temporal seizures may be subtle and manifest with pallor, apnoea and behavioral arrest. There may be earlier and more marked motor manifestations including tonic seizures and epileptic spasms, which may reflect different patterns of spread in the developing brain. […] CAUTION Temporal focal impaired awareness seizures can have similar features to frontal focal impaired awareness seizures, however impaired awareness seizures of temporal origin tend to have a slower onset and progression, and postictal confusion is more pronounced. […] CAUTION Temporal focal impaired awareness seizures need to be distinguished from absence seizures. While both may have automatisms, temporal lobe seizures are typically longer ( 30 seconds), associated with pallor, and followed by postictal confusion.

Patients with temporal lobe epilepsy typically have material-specific deficits in memory function as the hippocampi are important structures for memory function. […] Aura, now called focal aware, seizures occur in approximately 80% of temporal lobe seizures. […] A complex partial seizure may evolve to a secondarily generalized tonic-clonic seizure. […] Patients usually experience a postictal period of confusion, which distinguishes temporal lobe epilepsy from absence seizures, which are not associated with postictal confusion. […] The risk of temporal lobe epilepsy is poorly controlled focal impaired awareness seizures, which leads to disability in home, work, and public safety such as driving restrictions. If the seizures often progress to bilateral tonic clonic then there is an increased risk of sudden unexpected death in epilepsy.

If the sclerosis is localised to the non-dominant hemisphere, patients may have difficulties with visual memory, for example remembering faces or places they have been.
- #49 TEMPORAL LOBE SEIZUREhttps://www.epilepsydiagnosis.org/seizure/temporal-overview.html
Temporal lobe seizures are characterized by behavioral arrest and impaired awareness. Automatisms are common during the seizure, and include oral and/or manual automatisms. There may sensory (auditory), emotional (fear), cognitive (deja vu) or autonomic features (epigastric sensation, tachycardia, colour change) prior to onset of impaired awareness. Postictal confusion typically occurs. […] Specific features suggest seizure onset in the dominant or non-dominant temporal lobe (see hemispheric lateralization). Ictal speech, spitting, vomiting, drinking, urge to urinate and automatisms with preserved consciousness suggest seizure onset in the non-dominant temporal lobe. Postictal speech disturbance suggests a dominant temporal lobe seizure. Upper limb dystonia is a useful lateralizing feature, lateralizing the seizure to the contralateral hemisphere. Conversely, manual automatisms usually occur on the ipsilateral side.

There’s a risk of irreversible neurocognitive decline with TLE. Neurocognitive decline means it becomes harder for you to learn, remember, make decisions or focus. […] The more seizures you have and the longer you have them, the greater your risk of: depression; anxiety; memory loss; sudden unexplained death in epilepsy (SUDEP). […] Many people find success in managing seizures with medications. Some people report being seizure-free after surgery.

Symptoms of a temporal lobe seizure include: Not being aware of the people and things around you. Staring. Lip smacking. Swallowing or chewing over and over. Finger movements, such as picking motions. […] After a temporal lobe seizure, you may: Be confused and have trouble speaking for a time. Be unable to recall what happened during the seizure. Be unaware of having had a seizure. Be very sleepy. […] Sometimes, what starts as a temporal lobe seizure becomes a generalized tonic-clonic seizure. This type of seizure causes shaking, known as convulsions, and loss of consciousness. It also is called a grand mal seizure. […] Over time, repeated temporal lobe seizures can cause the part of the brain involved in learning and memory to shrink. This area of the brain is called the hippocampus. The loss of brain cells in the hippocampus may cause memory problems.

The major cognitive impairment in mesial temporal lobe epilepsy is a progressive memory impairment. This involves declarative memory impairment, including episodic memory and semantic memory, and is worse when medications fail to control seizures. Mesial temporal lobe epilepsy arising from the language dominant hemisphere impairs verbal memory, and mesial temporal lobe epilepsy arising from the language non-dominant hemisphere impairs nonverbal memory. […] Psychiatric disorders are more common among those with epilepsy, and the highest prevalence occurs among those with temporal lobe epilepsy. The most common psychiatric comorbidity is major depressive disorder. Other disorders include post-traumatic stress disorder, generalized anxiety disorder, psychosis, obsessive-compulsive disorder, schizophrenia, bipolar disorder, substance use disorder, and a ~9% prevalence of suicide.

Patients can recall the initial phase but have little or no recollection of the period of reduced consciousness. The postictal phase is usually marked by confusion. Ictal and postictal dysphasia are common when the seizure focus is in the language-dominant temporal lobe. Occasionally, focal seizures may develop into a tonic-clonic seizure. […] The initial symptoms of the seizure depend on which temporal lobe is affected, the location and function of the seizure network and the seizure propagation pattern. Initial symptoms may be autonomic, cognitive, emotional, or sensory. […] Many patients, especially those with hippocampal sclerosis, have cognitive difficulties in addition to seizures.

Kids with temporal lobe epilepsy have seizures that start in one of the temporal lobes of the brain. The seizures in temporal lobe epilepsy are focal seizures. Focal seizures begin in one area of the brain, and may or may not spread to other areas of the brain. Some children may have auras, which are a type of focal onset aware seizure that can include: dj vu (a feeling of already having been in the present situation), a smell, taste, sound, or vision, an emotion (such as fear), nausea or a rising sensation in the belly. Someone having a focal onset impaired awareness seizure may stare, rub their hands, or smack their lips. It may be hard to speak or understand language during the seizure. Sometimes a focal seizure can develop (or generalize) into a seizure that involves both sides of the brain. This is called a focal to bilateral tonic-clonic seizure. With this type of seizure, the whole body jerks with forceful movements.

Temporal lobe epilepsy, or TLE, is the most common type of focal epilepsy. TLE affects about 6 out of every 10 people with focal epilepsy. […] In TLE, seizures start in a specific part of the brain. That part is called the temporal lobe. […] Febrile seizures are the most common risk factor for TLE. These seizures happen as a result of a high fever. Babies and children who have a seizure caused by a high fever for 15 minutes or longer are more likely to develop TLE later. But most people who have febrile seizures do not develop TLE. […] Seizures that occur in TLE include focal aware seizures and focal impaired awareness seizures. […] A focal aware seizure is a seizure that starts in one area of the brain and stays in that area. […] A focal impaired awareness seizure is a type of seizure where the person is not aware of what is happening around them. […] Most people with TLE can get their seizures under control and lead normal lives. In children with TLE, seizures may even disappear over time. People who have a harder time controlling their seizures may also have mood or memory problems.

[…] After a temporal lobe seizure occurs, you may experience: trouble speaking, confusion, being unaware a seizure occurred, intense fatigue. […] Rarely, people who experience a temporal lobe seizure will go on to experience a generalized tonic-clonic (grand mal) seizure, which causes convulsions and a loss of consciousness. […] While temporal lobe epilepsy can be successfully treated with medication or surgery, it always poses a danger to those living with it and possibly others, especially during the operation of heavy machinery or motor vehicles. Additionally, people with epilepsy who are resistant to drug treatment are more likely to experience memory and mood problems. These challenges can lead to a reduced quality of life and an increased risk of death. If properly managed through medications and lifestyle adaptations, people with seizures can live a full life.

Patients with temporal lobe epilepsy typically have material-specific deficits in memory function as the hippocampi are important structures for memory function. […] Aura, now called focal aware, seizures occur in approximately 80% of temporal lobe seizures. […] A complex partial seizure may evolve to a secondarily generalized tonic-clonic seizure. […] Patients usually experience a postictal period of confusion, which distinguishes temporal lobe epilepsy from absence seizures, which are not associated with postictal confusion. […] The risk of temporal lobe epilepsy is poorly controlled focal impaired awareness seizures, which leads to disability in home, work, and public safety such as driving restrictions. If the seizures often progress to bilateral tonic clonic then there is an increased risk of sudden unexpected death in epilepsy.
