Padaczka płata czołowego – Etiologia i przyczyny

Padaczka płata czołowego
Etiologia i przyczyny

Padaczka płata czołowego (FLE) stanowi 20-30% padaczek ogniskowych i charakteryzuje się napadami z ogniskiem w płacie czołowym, często występującymi nocą. Etiologia jest zróżnicowana: około 50% przypadków ma nieznaną przyczynę (idiopatyczna). Wśród znanych przyczyn dominują dysplazje korowe (zwłaszcza typ II), mutacje genetyczne (m.in. CHRNA2, CHRNA4, CHRNB2 w ADNFLE/SHE), nowotwory mózgu (stanowiące około 1/3 przypadków), urazy czaszkowo-mózgowe, udary mózgu oraz infekcje OUN. Patofizjologia opiera się na nieprawidłowej aktywności elektrycznej neuronów płata czołowego, z charakterystycznymi napadami krótkotrwałymi (<30 s), często w klasterach, z gwałtownymi ruchami i zachowaną świadomością. Diagnostyka wymaga zaawansowanego obrazowania (MRI, SPECT, PET), gdyż standardowe EEG może być niewystarczające.

Etiologia padaczki płata czołowego

Padaczka płata czołowego (ang. Frontal Lobe Epilepsy, FLE) to jedna z najczęstszych form padaczki ogniskowej, stanowiąca około 20-30% wszystkich przypadków padaczki ogniskowej. Charakteryzuje się występowaniem nawracających napadów padaczkowych, których ognisko znajduje się w płacie czołowym mózgu. Napady te mogą występować zarówno w stanie czuwania, jak i podczas snu, chociaż badania wskazują na ich częstsze występowanie w nocy.¹²³

Przyczyny padaczki płata czołowego są różnorodne i złożone. U około połowy pacjentów z tym schorzeniem etiologia pozostaje nieznana (idiopatyczna), co stanowi istotne wyzwanie diagnostyczne.¹²³ W przypadkach o znanej etiologii można wyróżnić kilka głównych kategorii przyczyn, które zostaną omówione poniżej.⁴

Zaburzenia rozwojowe mózgu

Nieprawidłowości rozwojowe mózgu stanowią istotną przyczynę padaczki płata czołowego. Około połowa przypadków padaczki płata czołowego o znanej etiologii jest związana z zaburzeniami rozwoju mózgu podczas życia płodowego.¹² Najczęściej występującą patologią w tej grupie jest dysplazja korowa, zwłaszcza dysplazja korowa typu II (typu Taylora), która coraz częściej jest identyfikowana jako zmiana padaczkorodna dzięki postępom w neuroobrazowaniu.¹²

Dysplazja korowa charakteryzuje się nieprawidłowym formowaniem się kory mózgowej, co prowadzi do zaburzeń w organizacji neuronów i połączeń nerwowych. Te nieprawidłowości strukturalne mogą zakłócać prawidłową aktywność elektryczną mózgu, co sprzyja powstawaniu napadów padaczkowych.¹

Przyczyny genetyczne

Czynniki genetyczne odgrywają istotną rolę w etiologii padaczki płata czołowego, szczególnie w przypadku autosomalnie dominującej padaczki płata czołowego związanej ze snem (autosomal dominant sleep-related hypermotor epilepsy, SHE, dawniej znanej jako autosomal dominant nocturnal frontal lobe epilepsy, ADNFLE).¹²

ADNFLE była pierwszą padaczką ogniskową zidentyfikowaną jako zaburzenie związane z pojedynczym genem. Mutacje w trzech genach kodujących podjednostki receptora nikotynowego acetylocholiny (nAChR) – alfa-2, alfa-4 i beta-2 – zostały powiązane z tym zespołem padaczkowym.¹ Konkretnie, mutacje w genach CHRNA2, CHRNA4 i CHRNB2 mogą powodować ADNFLE.¹²

Uważa się, że mutacje te wpływają na normalny proces uwalniania i wychwytu neuroprzekaźników w mózgu, co prowadzi do zmian w sygnalizacji między neuronami, które mogą wyzwalać nieprawidłową aktywność mózgu związaną z napadami.¹ Dziedziczenie tego typu padaczki następuje w sposób autosomalny dominujący, co oznacza, że jeśli jedno z rodziców ma to zaburzenie, dziecko ma 50% szans na odziedziczenie zmutowanego genu.¹

Warto zaznaczyć, że mutacje w tych trzech genach odpowiadają za mniej niż 20% przypadków SHE/ADSHE, co odzwierciedla heterogenność genetyczną tego zespołu i możliwą rolę innych systemów poza cholinergicznym w jego patogenezie.¹ W ostatnich latach zidentyfikowano również mutacje w innych genach związanych z padaczką płata czołowego.¹

Nowotwory mózgu

Nowotwory mózgu stanowią około jednej trzeciej wszystkich przypadków padaczki płata czołowego.¹² Zarówno guzy łagodne, jak i złośliwe mogą wywoływać napady padaczkowe poprzez zakłócanie normalnej aktywności elektrycznej w mózgu.

Mechanizm padaczkorodnego działania nowotworów obejmuje kilka możliwych procesów, w tym bezpośredni ucisk na otaczającą tkankę mózgową, zaburzenia w mikrokrążeniu mózgowym, zmiany w lokalnym środowisku metabolicznym oraz bezpośrednie oddziaływanie na funkcje synaptyczne.¹ W przypadku guzów płata czołowego, ich lokalizacja w obszarach odpowiedzialnych za planowanie ruchów i kontrolę funkcji motorycznych może wyjaśniać charakterystyczne objawy ruchowe podczas napadów.¹

Urazy mózgu

Uraz czaszkowo-mózgowy jest bardzo częstą przyczyną uszkodzenia płatów czołowych i może prowadzić do rozwoju padaczki pourazowej.¹ Uszkodzenie tkanki mózgowej w wyniku urazu może spowodować tworzenie się blizn (glioza), które mogą stać się ogniskiem padaczkorodnym.¹

Napady padaczkowe wynikające bezpośrednio z urazu głowy zwykle pojawiają się w ciągu kilku miesięcy od zdarzenia, jednak w niektórych przypadkach mogą rozwinąć się nawet po kilku latach.¹ Ciężkość urazu oraz lokalizacja uszkodzenia mają istotny wpływ na prawdopodobieństwo wystąpienia padaczki pourazowej.¹

Zaburzenia naczyniowe

Udar mózgu jest istotnym czynnikiem etiologicznym w padaczce płata czołowego, szczególnie u pacjentów w starszym wieku.¹² Niedokrwienie tkanki mózgowej prowadzi do zmian strukturalnych i funkcjonalnych, które mogą stać się źródłem napadów padaczkowych.¹

Oprócz udarów, inne patologie naczyniowe mogą również przyczyniać się do rozwoju padaczki płata czołowego. Wyróżnia się trzy główne typy malformacji naczyniowych: malformacje tętniczo-żylne, naczyniaki jamiste i naczyniaki żylne.¹ Wszystkie te nieprawidłowości mogą zakłócać prawidłowe funkcjonowanie tkanki mózgowej i prowadzić do napadów padaczkowych.¹

Infekcje i stany zapalne

Infekcje ośrodkowego układu nerwowego, takie jak zapalenie mózgu (encephalitis) i zapalenie opon mózgowo-rdzeniowych (meningitis), mogą prowadzić do rozwoju padaczki płata czołowego.¹²

Chociaż zapalenie mózgu często prowadzi do padaczki płata skroniowego, napady płata czołowego również mogą wystąpić.¹ Infekcje mogą powodować bezpośrednie uszkodzenie tkanki mózgowej, a także inicjować procesy zapalne, które zmieniają funkcjonowanie neuronów i zwiększają ich pobudliwość.¹

Stany zapalne w mózgu, nawet o etiologii nieinfekcyjnej, mogą również przyczyniać się do rozwoju padaczki. Badania wykazały wyższą ekspresję genów związanych z procesami prozapalnymi, takich jak interleukina-1 beta, IL-6 i czynnik martwicy nowotworów alfa (TNF-alfa), u osób z padaczką płata czołowego w porównaniu do osób bez padaczki.¹

Inne przyczyny

Oprócz wyżej wymienionych czynników, padaczka płata czołowego może być spowodowana przez szereg innych przyczyn, w tym:

Niedotlenienie mózgu podczas porodu lub w innych okolicznościach, które może prowadzić do uszkodzenia tkanki mózgowej i późniejszego rozwoju padaczki¹
Zaburzenia metaboliczne, które mogą wpływać na funkcjonowanie neuronów i zwiększać prawdopodobieństwo wystąpienia napadów padaczkowych¹
Choroby neurodegeneracyjne, takie jak choroba Alzheimera czy ataksja, które mogą prowadzić do zmian strukturalnych w mózgu sprzyjających rozwojowi padaczki¹
Powikłania okołoporodowe, które mogą prowadzić do uszkodzenia mózgu i rozwoju padaczki w późniejszym życiu¹

Czynniki wyzwalające napady

Warto również wspomnieć o czynnikach, które mogą wyzwalać napady u pacjentów z już istniejącą padaczką płata czołowego. Do takich czynników należą:

Deprywacja snu, która jest szczególnie istotnym czynnikiem wyzwalającym napady płata czołowego¹
Stres, który może prowokować napady i sam w sobie może być wywołany przez napady, tworząc błędne koło¹
Spożycie alkoholu i palenie tytoniu¹
Zmiany hormonalne, np. podczas miesiączki¹
Niektóre leki i substancje psychoaktywne¹
Przebudzenie ze snu¹

Patofizjologia napadów płata czołowego

Patofizjologia napadów płata czołowego jest złożona i nie do końca poznana. Obecny stan wiedzy wskazuje jednak na kilka kluczowych mechanizmów leżących u podłoża tego typu padaczki.

Podstawowym mechanizmem napadów padaczkowych jest nieprawidłowa aktywność elektryczna neuronów w mózgu. W przypadku padaczki płata czołowego, neurony w płacie czołowym wysyłają sygnały w sposób niekontrolowany, co prowadzi do charakterystycznych objawów klinicznych.¹ Ta nieprawidłowa aktywność może rozprzestrzeniać się na inne obszary mózgu, powodując różnorodne manifestacje kliniczne, w zależności od zaangażowanych struktur.¹

W przypadku napadów z zaburzeniami świadomości, badania wykazały, że w porównaniu do napadów z zachowaną świadomością, występuje zwiększona aktywność w szerokim zakresie częstotliwości w rozległych obszarach kory mózgowej, wykraczających poza obszar ogniska padaczkowego. Jest to mechanizm odmienny od obserwowanego w padaczce płata skroniowego, gdzie zaburzenia świadomości wiążą się z wolnofalową aktywnością korową.¹²

W przypadku autosomalnie dominującej padaczki płata czołowego związanej ze snem (ADNFLE), patofizjologia wiąże się z dysfunkcją receptorów nikotynowych acetylocholiny. Mutacje w genach kodujących podjednostki tych receptorów prowadzą do zaburzeń w transmisji cholinergicznej, co wpływa na regulację aktywności mózgu podczas snu i może prowadzić do napadów padaczkowych.¹ Nie jest jednak do końca jasne, dlaczego mutacje te powodują napady właśnie w płacie czołowym, a nie w innych częściach mózgu.¹

Interesujące jest, że padaczka płata czołowego może być związana z aktywacją swoistych obwodów w pierwotnej korze somatomotorycznej i korze przedruchowej przez aktywność padaczkową, co może tłumaczyć charakterystyczne zachowania ruchowe obserwowane podczas napadów, w tym czasami złożone, pozornie celowe zachowania, takie jak uderzanie, kopanie czy wykonywanie ruchów kończynami przypominających jazdę na rowerze.¹

Cechy charakterystyczne napadów płata czołowego

Napady padaczkowe pochodzące z płata czołowego mają kilka charakterystycznych cech, które odróżniają je od napadów pochodzących z innych części mózgu:

Najczęściej są krótkotrwałe, trwają zwykle krócej niż 30 sekund¹
Często występują w nocy lub podczas snu¹²
Mają tendencję do występowania w skupiskach (klasterach), czyli w seriach kilku napadów w krótkim odstępie czasu¹²
Charakteryzują się często dziwacznymi, gwałtownymi ruchami, takimi jak kopanie, uderzanie, ruchy rowerowe kończyn¹²
Mogą być związane z wokalizacjami, czasem w postaci krzyku, wulgaryzmów lub śmiechu¹²
Często zachowana jest świadomość podczas napadu, co może prowadzić do błędnego rozpoznania jako zaburzeń niepadaczkowych¹
W zapisie EEG może nie być widocznych wyraźnych wzorców napadowych lub mogą być one maskowane przez artefakty ruchowe¹

Ze względu na te cechy, padaczka płata czołowego może być trudna do zdiagnozowania i bywa mylona z parasomnią (np. lękami nocnymi), zaburzeniami psychicznymi lub napadami niepadaczkowymi (psychogennymi).¹²

Diagnostyka i leczenie

Diagnostyka padaczki płata czołowego wymaga kompleksowego podejścia. Z uwagi na często trudne do interpretacji objawy kliniczne oraz wyniki standardowego EEG, konieczne jest wykorzystanie zaawansowanych technik obrazowania, takich jak:¹

MRI z sekwencjami specyficznymi dla epilepsji¹
SPECT (tomografia emisyjna pojedynczego fotonu)¹
SISCOM (subtrakcyjny ictal SPECT korelowany z MRI)¹
PET (pozytonowa tomografia emisyjna)¹

Leczenie padaczki płata czołowego opiera się przede wszystkim na farmakoterapii z wykorzystaniem leków przeciwpadaczkowych. W przypadku autosomalnie dominującej padaczki płata czołowego związanej ze snem (ADNFLE), dobra odpowiedź obserwowana jest często przy stosowaniu karbamazepiny, nawet w niskich dawkach.¹

W przypadku lekooporności, rozważane mogą być metody chirurgiczne, takie jak resekcja ogniska padaczkorodnego. Przed operacją konieczne jest dokładne zlokalizowanie obszaru generującego napady, co bywa trudne w przypadku padaczki płata czołowego, szczególnie gdy standardowe badania obrazowe nie wykazują zmian strukturalnych.¹²

Dla pacjentów, którzy nie reagują na leki przeciwpadaczkowe i nie kwalifikują się do leczenia operacyjnego, alternatywnym podejściem może być elektryczna stymulacja mózgu.¹

Istnieją również dowody na skuteczność diety ketogenicznej w leczeniu napadów padaczkowych, szczególnie u dzieci.¹

Ważnym elementem terapii jest także identyfikacja i unikanie czynników wyzwalających napady, takich jak deprywacja snu, stres, alkohol czy niektóre leki.¹

#1 Frontal lobe epilepsy – Wikipedia
https://en.wikipedia.org/wiki/Frontal_lobe_epilepsy
Frontal lobe epilepsy (FLE) is a neurological disorder that is characterized by brief, recurring seizures arising in the frontal lobes of the brain, that often occur during sleep. […] There are many different causes of frontal lobe epilepsy ranging from genetics to head trauma that result in lesions in the frontal lobes. […] One of the major reasons for FLE is abnormal cognitive development or sometimes congenital abnormal brain development. Other causes are tumors, head trauma, and genetics. […] Tumors account for about one-third of all frontal lobe epilepsy cases. […] Seizures originating directly from head trauma usually occur within a few months, but occasionally they can take years to manifest.

[…] For about half of people who have frontal lobe epilepsy, the cause is not known.
#1 Frontal Lobe Epilepsy: Causes & Symptoms – Unique Community Services
https://uniquecs.co.uk/blog/frontal-lobe-epilepsy/
Frontal lobe seizures can occur when a person is awake or asleep, although numbers show they are more frequent at night. […] Possible causes of frontal lobe seizures include: Tumours, Differences in brain development, Traumatic brain injury, Stroke, Severe brain infections. […] Almost half of frontal lobe seizures are caused by a difference in brain development during pregnancy. The variation occurs in the brains outer layer (cerebral cortex) or cerebrum responsible for higher processes, including consciousness, memory and reasoning. The underlying reason for this alteration in brain development is unknown. […] Other possible causes of frontal lobe epilepsy include damage of the frontal lobe region caused by mechanical trauma, stroke or abnormal growth of tumour brain cells. […] Nocturnal frontal lobe epilepsy is associated with genetic mutations and appears to run in families. This form of epilepsy is called autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) and is very infrequent.
#1 Frontal Lobe Epilepsy: Practice Essentials, Background, Etiology
https://emedicine.medscape.com/article/1184076-overview
Frontal lobe epilepsy is characterized by recurrent seizures arising from the frontal lobes. Frequently, seizure types are focal onset with preserved or impaired awareness, often with progression to bilateral tonic-clonic activity. […] Disease conditions commonly associated with frontal lobe epilepsy are frequently symptomatic, including congenital causes (such as cortical dysgenesis, gliosis, vascular malformations), neoplasms, head trauma, infections, and anoxia. […] With improvements in neuroimaging, focal cortical dysplasias are increasingly being identified as epileptogenic lesions. […] Reviews indicate that the epileptogenic lesion in approximately one third of patients with refractory frontal lobe seizures is a tumor. […] Head trauma is a very frequent cause of damage to the frontal lobes.

https://emedicine.medscape.com/article/1184076-overview
Three main types [of vascular malformations] are recognized: arteriovenous malformations, cavernous angiomas, and venous angiomas. […] Gliosis is identified in many pathologic specimens following surgical resection for frontal lobe epilepsy. […] Although encephalitis commonly produces temporal lobe epilepsy, frontal lobe seizures may occur. […] The seizures of autosomal dominant sleep-related hypermotor epilepsy (SHE)(formerly known as ADNFLE for autosomal dominant nocturnal frontal lobe epilepsy), which are mostly originating in the frontal lobe, are clinically characterized by brief, nocturnal motor seizures that often occur in clusters, mainly during non-REM sleep. Seizure onset is typically in childhood, but can range from infancy to adulthood. Affected patients have normal neurologic exams and intellect. These seizures typically respond well to carbamazepine (often low doses) and are lifelong, though not progressive. Differentiation from parasomnias remains a challenge. […] Autosomal dominant SHE was the first focal epilepsy identified as a single gene disorder. Mutations in 3 nicotinic acetylcholine receptor genes (nAChR alpha-2, alpha-4 and beta-2 subunits) have been associated with this epilepsy syndrome.

https://medlineplus.gov/genetics/condition/autosomal-dominant-nocturnal-frontal-lobe-epilepsy/
Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is an uncommon form of epilepsy that runs in families. […] The seizures associated with ADNFLE begin in areas of the brain called the frontal lobes. […] Mutations in the CHRNA2, CHRNA4, and CHRNB2 genes can cause ADNFLE. […] Researchers believe that mutations in the CHRNA2, CHRNA4, and CHRNB2 genes affect the normal release and uptake of certain neurotransmitters in the brain. […] The resulting changes in signaling between neurons likely trigger the abnormal brain activity associated with seizures. […] It is unclear why mutations in the CHRNA2, CHRNA4, and CHRNB2 genes cause seizures in the frontal lobes rather than elsewhere in the brain. […] The genetic cause of ADNFLE has been identified in only a small percentage of affected families. […] Researchers are searching for other genetic changes, including mutations in other subunits of nAChR, that may underlie the condition.

One rare form of FLE autosomal dominant nocturnal frontal lobe epilepsy has a strong genetic component. Autosomal dominant means that if one of a persons parents has the disorder, then that person has a 50 percent chance of inheriting the mutated gene. In this type of FLE, the genetic mutation is found in the CHRNA4 and CHRNB2 genes, which code for nicotinic receptors in the brain.

https://resources.healthgrades.com/right-care/epilepsy/frontal-lobe-seizures
Epilepsy, infections, or stroke can cause frontal lobe seizures. […] However, some people do experience frontal lobe seizures due to frontal lobe epilepsy. Frontal lobe epilepsy is a particularly common type of epilepsy syndrome. […] Some factors may cause provoked seizures or lead to the development of epilepsy longer term. These factors can include: infection, brain injury, stroke, brain tumor, withdrawal, certain medications, low blood sugar, drug misuse, in children, high fever. […] Frontal lobe seizures can occur due to frontal lobe epilepsy, a neurological condition that causes electrical brain activity to produce seizures. Frontal lobe epilepsy is a particularly common form of epilepsy. […] Other causes of frontal lobe epilepsy can include: atypical brain development or structure, genetic differences, neurodegenerative conditions, such as: Alzheimerâs disease, ataxia. […] A 2018 study identifies certain genetic traits that may contribute to frontal lobe seizures in epilepsy. This includes hereditary genes that may increase the chance of having epilepsy if one of your biological parents has the gene.
#1 Brain tumour seizure and epilepsy | The Brain Tumour Charity
https://www.thebraintumourcharity.org/living-with-a-brain-tumour/side-effects/seizures-epilepsy-and-brain-tumours/
A seizure happens when theres a burst of abnormal electrical activity that disturbs the way the brain normally works, mixing up the messages. This causes a variety of symptoms. […] Epilepsy caused by a brain tumour might be related to cells around the tumour that have developed abnormally. Or they may be due to an imbalance of chemicals in the brain caused by the tumour. Both of these can interfere with the normal electrical activity in the brain, leading to brain tumour epilepsy. […] Although epilepsy is more likely in certain low grade brain tumours, we dont fully understand why this is the case. […] Suggestions include abnormally developed cells around the brain tumour that fire (send signals) more often, causing disorganised electrical activity in the brain, which leads to seizures. This is sometimes the cause in people with non-brain tumour-related epilepsy. […] Or it could be due to the tumour causing a disturbance in the balance of chemicals in the brain, causing the nerve cells to fire more often.

Additionally, issues during prenatal development or complications during birth can also contribute to the development of frontal lobe epilepsy. Understanding the multifaceted nature of these potential causes is crucial in diagnosing and managing this type of epilepsy effectively. […] Genetic predisposition can play a role in the development of frontal lobe epilepsy, with certain genes increasing the likelihood of seizures. […] Head trauma, such as a severe injury to the frontal lobe from a car accident or sports-related impact, can trigger epilepsy. […] Developmental abnormalities in the frontal lobe, present from birth or due to conditions like neurofibromatosis, may lead to epilepsy. […] Brain tumors located in the frontal lobe can cause disruptions in brain activity, potentially resulting in the onset of epilepsy.

https://www.myepilepsyteam.com/resources/frontal-lobe-epilepsy-an-overview
Frontal lobe epilepsy (FLE) is a neurological disorder that is characterized by seizures in the frontal lobe of the brain. […] In the majority of cases, FLE is caused by an abnormality in the frontal lobe of the brain. These abnormalities can include tumors, strokes, hemorrhages, infections, or traumatic brain injuries. An abnormal lesion in the brain can disrupt the brains normal processing and pathway of electrical impulses, making it a prime location for seizures to develop. […] Genetics may also play a role in FLE. In one study, researchers analyzed tissue from the olfactory bulb, which enables the sense of smell, from deceased people who had FLE in their lifetime. They found higher numbers of genes related to proinflammatory processes, such as interleukin (IL)-1 beta, IL-6, and tumor necrosis factor (TNF)-alpha, in people with FLE than people without.

Most of the focal epilepsies are the result of a structural brain abnormality, even though this cannot always be identified. These cases represent most cases of adult-onset epilepsy, although these are common in childhood as well. If imaging studies are normal, the cause remains unknown. […] Epilepsy is a disease associated with lasting derangement of brain function and predisposition to recurring seizures. It may arise from a variety of genetic, structural, metabolic, immune, and infectious causes. Seizures and epilepsy are generally divided into focal and generalized according to the mode of seizure onset as well as into genetic, structural, metabolic, immune, infectious, or unknown according to the underlying cause or etiology.

https://www.mayoclinic.org/diseases-conditions/frontal-lobe-seizures/diagnosis-treatment/drc-20353962
You may find that some things trigger seizures. Seizures can be triggered by alcohol intake, smoking and, especially, lack of sleep. There also is evidence that severe stress can provoke seizures, and that seizures themselves can cause stress. Avoiding these triggers where possible might help improve seizure control. […] Researchers are looking into these therapies to determine their safety and effectiveness. However, good evidence that they’re effective at reducing seizures is mostly still lacking. There is some evidence that a ketogenic diet might be effective for treating seizures, particularly in children. […] Some people who have epilepsy are frustrated by their condition. Frontal lobe seizures can involve loud utterances or sexual movements that may make the person with epilepsy anxious.

https://my.clevelandclinic.org/health/diseases/17011-frontal-lobe-epilepsy
Frontal lobe epilepsy is a type of seizure disorder affecting your frontal lobes. It causes frontal lobe seizures, which is a pattern of abnormal electrical activity in your brain. […] Abnormal electrical activity in your frontal lobe causes frontal lobe epilepsy. Neurons (nerve cells) usually send signals to other cells in your brain. When a frontal lobe seizure happens, neurons fire signals uncontrollably. […] Common reasons why this may happen could include: Abnormal formation of your brain during fetal development, Brain infections, Stroke, Traumatic brain injury, Brain tumor, Genetic variations. […] Sometimes, the cause isn’t known.
#1 FRONTAL LOBE SEIZURE
https://www.epilepsydiagnosis.org/seizure/frontal-lobe-overview.html
The frontal lobe is the largest lobe. Seizures involving frontal lobe network have distinctive features depending on the area of the frontal lobe involved. Motor features are prominent and may be hyperkinetic (e.g. pelvic thrusting, bipedal kicking or pedalling) or asymmetric tonic in nature. The motor feature may not be the initial sign and the seizure may be a focal aware non-motor seizure with the prominent motor phase occurring a brief period after seizure onset. Seizures are typically brief overall, and can have prominent vocalization, bizarre behavior, urinary incontinence, and head and eye deviation. Seizures may be exclusively nocturnal and often cluster. The ictal EEG may not show ictal patterns or may be obscured by movement artifact. […] When awareness is impaired, focal impaired awareness seizures of frontal origin can be difficult to distinguish from absence seizures. […] Frontal lobe seizures may be mis-diagnosed as non-epileptic seizures as there may be bilateral motor phenomena with preserved awareness, and the ictal EEG can be normal.

We found that frontal lobe FIA seizures had abnormal increased activity in widespread brain regions in contrast to FA seizures where increased activity was confined mainly to the frontal lobe of seizure onset. […] Our analysis demonstrated that frontal lobe FIA seizures had greater broadband power increases across frequencies in widespread areas of the cortex whereas FA seizures had relatively localized increases in the frontal lobe of onset. […] Interestingly, our present findings show that the mechanisms by which FLE leads to impaired consciousness are different from the above-mentioned mechanisms in TLE. We found that unlike TLE, in frontal lobe FIA seizures, there is an increase in icEEG activity outside the region of seizure onset across a wide range of frequencies, not just in the slow delta frequency range.

Nocturnal frontal lobe epilepsy (NFLE) is a syndrome of heterogeneous etiology, characterized by the occurrence of sleep-related seizures with different complexity and duration. […] NFLE is not a homogeneous disease as familial, idiopathic, sporadic, cryptogenetic, or symptomatic forms do exist. […] A family history for epilepsy is frequently observed in NFLE patients. […] The genetic origin of the disease was confirmed by a linkage study in Australian kindred. […] Studies, conducted in patients with drug-resistant epilepsy, have shown that type II focal cortical dysplasia (type II FCD; Taylor-type cortical dysplasia) is the most frequent etiological substrate of NFLE. […] The findings of a genetic alteration of the cholinergic system and the in vivo documentation of an alteration of nAChR density distribution in ADNFLE patients may give some insights into understanding the relationships between genes, epileptogenesis, and arousal regulatory processes. […] In summary, ADNFLE is a heterogeneous genetic syndrome that can be incidental to mutations in different genes; to date, mutations have been reported in six genes. […] NFLE is generally considered a benign clinical entity, although severe, drug-resistant forms do exist.
#1 DIRECTED AGGRESSIVE BEHAVIOR IN FRONTAL LOBE EPILEPSY: A VIDEO-EEG AND ICTAL SPECT CASE STUDY
https://pmc.ncbi.nlm.nih.gov/articles/PMC2849702/
Frontal lobe seizures may manifest bizarre behaviors such as thrashing, kicking, genital manipulation, unusual facial expressions, and articulate vocalizations. Aggressive and violent behaviors have also been associated with epilepsy, especially temporal or frontal lobe seizures. […] More so than seizures arising from other brain locations, frontal lobe seizures may exhibit bizarre and unusual behaviors. It is generally agreed among neurologists and epileptologists that well-organized, purposeful, complex, goal-directed behavior is highly unlikely during a seizure. […] This study demonstrates a rare case of directed and interactive aggressive verbal and physical behavior during frontal lobe seizures. The pathophysiology of this behavior is likely related to activation of circuitry in the primary somatomotor and premotor cortex by epileptic activity.

Frontal lobe epilepsy can be hard to diagnose. Its symptoms can be mistaken for mental health problems or sleep disorders such as night terrors. It also is possible that some symptoms of frontal lobe seizures are the result of seizures that begin in other parts of the brain. […] Over the past decade, treatment options have increased for frontal lobe seizures. There are newer types of anti-seizure medicines. There also are a variety of surgical procedures that might help if medicines don’t work. […] If your seizures can’t be controlled with medicines, surgery might be an option. Before surgery, the goal is to find the areas of the brain where seizures occur. […] Imaging techniques can help identify the area generating seizures. These include single-photon emission computerized tomography (SPECT) and subtraction ictal SPECT coregistered to MRI (SISCOM).

Frontal lobe epilepsy affects the area of the brain responsible for speech, motor skills, personality, and forming memories. […] A genetic component could cause frontal lobe epilepsy (FLE) with a 50% inheritability rate for the abnormal gene. Other abnormalities such as a stroke, injury, tumors, or infections can cause FLE, but the cause is unknown approximately half of the time. […] The seizures may be exclusively nocturnal and appear in clusters, which are closely grouped series of seizures. […] A diagnosis is needed from one of the following methods: electroencephalogram (EEG), computed tomography (CT or CAT) scan, magnetic resonance imaging (MRI), or positron emission tomography (PET) scan. Following a diagnosis, doctors would map the brain and pinpoint the correct area where the abnormal activity is taking place to determine the best course of action.

https://uniquecs.co.uk/blog/frontal-lobe-epilepsy/
Frontal lobe seizures can occur when a person is awake or asleep, although numbers show they are more frequent at night. […] Possible causes of frontal lobe seizures include: Tumours, Differences in brain development, Traumatic brain injury, Stroke, Severe brain infections. […] Almost half of frontal lobe seizures are caused by a difference in brain development during pregnancy. The variation occurs in the brains outer layer (cerebral cortex) or cerebrum responsible for higher processes, including consciousness, memory and reasoning. The underlying reason for this alteration in brain development is unknown. […] Other possible causes of frontal lobe epilepsy include damage of the frontal lobe region caused by mechanical trauma, stroke or abnormal growth of tumour brain cells. […] Nocturnal frontal lobe epilepsy is associated with genetic mutations and appears to run in families. This form of epilepsy is called autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) and is very infrequent.

Frontal lobe epilepsy is a type of seizure disorder affecting your frontal lobes. It causes frontal lobe seizures, which is a pattern of abnormal electrical activity in your brain. […] Abnormal electrical activity in your frontal lobe causes frontal lobe epilepsy. Neurons (nerve cells) usually send signals to other cells in your brain. When a frontal lobe seizure happens, neurons fire signals uncontrollably. […] Common reasons why this may happen could include: Abnormal formation of your brain during fetal development, Brain infections, Stroke, Traumatic brain injury, Brain tumor, Genetic variations. […] Sometimes, the cause isn’t known.

Frontal lobe seizures can also be triggered by conditions such as abnormal brain tissue, infection, injury, stroke, tumors, or other factors. […] Frontal lobe seizures can be attributed to various factors. Approximately half of these seizures result from brain development issues, where the cortex, the outermost layer of the brain, fails to form properly during fetal development. Other causes of frontal lobe seizures include brain infections, brain injuries or trauma such as stroke, and the presence of brain tumors or lesions. There is also a rare form of nocturnal frontal lobe epilepsy called autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE), which is caused by genetic mutations and can be inherited from parents. However, for around half of the individuals with frontal lobe epilepsy, the specific cause remains unknown.

Three main types [of vascular malformations] are recognized: arteriovenous malformations, cavernous angiomas, and venous angiomas. […] Gliosis is identified in many pathologic specimens following surgical resection for frontal lobe epilepsy. […] Although encephalitis commonly produces temporal lobe epilepsy, frontal lobe seizures may occur. […] The seizures of autosomal dominant sleep-related hypermotor epilepsy (SHE)(formerly known as ADNFLE for autosomal dominant nocturnal frontal lobe epilepsy), which are mostly originating in the frontal lobe, are clinically characterized by brief, nocturnal motor seizures that often occur in clusters, mainly during non-REM sleep. Seizure onset is typically in childhood, but can range from infancy to adulthood. Affected patients have normal neurologic exams and intellect. These seizures typically respond well to carbamazepine (often low doses) and are lifelong, though not progressive. Differentiation from parasomnias remains a challenge. […] Autosomal dominant SHE was the first focal epilepsy identified as a single gene disorder. Mutations in 3 nicotinic acetylcholine receptor genes (nAChR alpha-2, alpha-4 and beta-2 subunits) have been associated with this epilepsy syndrome.

Frontal lobe epilepsy is characterized by recurrent seizures arising from the frontal lobes. Frequently, seizure types are focal onset with preserved or impaired awareness, often with progression to bilateral tonic-clonic activity. […] Disease conditions commonly associated with frontal lobe epilepsy are frequently symptomatic, including congenital causes (such as cortical dysgenesis, gliosis, vascular malformations), neoplasms, head trauma, infections, and anoxia. […] With improvements in neuroimaging, focal cortical dysplasias are increasingly being identified as epileptogenic lesions. […] Reviews indicate that the epileptogenic lesion in approximately one third of patients with refractory frontal lobe seizures is a tumor. […] Head trauma is a very frequent cause of damage to the frontal lobes.
#2 All About Frontal Lobe Epilepsy (FLE)Healthline
https://www.healthline.com/health/epilepsy/frontal-lobe-epilepsy
Frontal lobe epilepsy (FLE) is a type of epilepsy that causes brief focal (partial) seizures stemming from one part of the brain. […] The exact causes of FLE are not fully understood. But itâs thought that genetics or structural changes in the brain may be a big contributor. […] Epilepsies can also be caused by: brain injuries, stroke, certain infections, such as encephalitis or meningitis, brain inflammation, tumors or cysts in the brain, irregular blood vessel formations in your central nervous system, conditions related to your genes. […] Seizures associated with frontal lobe epilepsy also tend to occur at random. But some known triggers for epileptic seizures may include: sleep deprivation, waking up, stress, hormonal changes, such as during menstruation, alcohol, certain medications, illegal substances.

#2 Focal seizures – Epilepsy Action
https://www.epilepsy.org.uk/info/seizures/focal-seizures
Frontal lobes are responsible for things like personality, emotions, concentration, problem solving and body movements. The symptoms of frontal lobe seizures can sometimes be mistaken for mental health problems or sleep disorders. […] Some people who have frontal lobe seizures only have them in their sleep. They dont usually last long, but often happen in clusters, with several happening in a short space of time. Your awareness may or may not be affected. […] Symptoms of seizures in the frontal lobes can include: pelvic thrusting, kicking, pedalling, thrashing or rocking movements; screaming, swearing or laughing; unintentionally passing urine (urinary incontinence); your head or eyes turning to one side; having unusual body movements, such as stretching one arm while the other bends; twitching, jerking or stiffening of muscles in one area of your body. The movements may sometimes spread bit by bit to other areas.
#2 FRONTAL LOBE SEIZURE
https://www.epilepsydiagnosis.org/seizure/frontal-lobe-overview.html
The frontal lobe is the largest lobe. Seizures involving frontal lobe network have distinctive features depending on the area of the frontal lobe involved. Motor features are prominent and may be hyperkinetic (e.g. pelvic thrusting, bipedal kicking or pedalling) or asymmetric tonic in nature. The motor feature may not be the initial sign and the seizure may be a focal aware non-motor seizure with the prominent motor phase occurring a brief period after seizure onset. Seizures are typically brief overall, and can have prominent vocalization, bizarre behavior, urinary incontinence, and head and eye deviation. Seizures may be exclusively nocturnal and often cluster. The ictal EEG may not show ictal patterns or may be obscured by movement artifact. […] When awareness is impaired, focal impaired awareness seizures of frontal origin can be difficult to distinguish from absence seizures. […] Frontal lobe seizures may be mis-diagnosed as non-epileptic seizures as there may be bilateral motor phenomena with preserved awareness, and the ictal EEG can be normal.
