Lęki nocne (parasomnia) – Patofizjologia i mechanizm

Lęki nocne (parasomnia)
Patofizjologia i mechanizm

Lęki nocne to parasomnia występująca w fazach 3 i 4 snu non-REM, charakteryzująca się nagłym wybudzeniem w stanie przerażenia, często z krzykiem i płaczem, pojawiająca się zwykle w pierwszej jednej trzeciej nocy (90 minut do 3 godzin po zaśnięciu). Epizody te wiążą się z częściowym wybudzeniem i nadmierną aktywacją układu współczulnego (tachypnoe, tachykardia, mydriasis, diaphoresis), przy jednoczesnej dezaktywacji szlaku wzgórzowo-korowego. EEG podczas epizodu wykazuje rozlane, hipersynchroniczne fale delta oraz aktywność alfa i beta, a SPECT wskazuje na aktywację szlaku wzgórzowo-kręgowego. Patogeneza pozostaje nie do końca poznana, jednak dysfunkcja układu serotoninergicznego i wzgórza, a także niedojrzałość obwodów GABAergicznych i cholinergicznych, są istotnymi czynnikami. Lęki nocne mają silny komponent genetyczny, z wysoką częstością występowania w rodzinach, zwłaszcza w kontekście chodzenia przez sen i nocnej padaczki płata czołowego. Czynniki ryzyka obejmują zaburzenia oddychania podczas snu (np. obturacyjny bezdech senny), stres, brak snu, choroby oraz niektóre leki (benzodiazepiny, SSRI, trójpierścieniowe leki przeciwdepresyjne).

Patogeneza lęków nocnych (parasomnii)

Lęki nocne (parasomnia) to zaburzenie snu charakteryzujące się nagłym wybudzeniem ze snu w stanie przerażenia, często z towarzyszącym krzykiem lub płaczem. Jest to rodzaj parasomnii związanej z nietypowymi zachowaniami fizycznymi i werbalnymi podczas snu.¹²

Mechanizm neurofizjologiczny

Lęki nocne występują podczas fazy snu non-REM (bez szybkich ruchów gałek ocznych), a dokładniej podczas faz 3 i 4 snu non-REM, czyli głębokiego snu wolnofalowego.³⁴ Epizody lęków nocnych pojawiają się zazwyczaj w pierwszej jednej trzeciej nocy, około 90 minut do 3 godzin po zaśnięciu, kiedy mózg znajduje się w stanie przejściowym między głębokim snem a czuwaniem.⁵⁶

Badania neurofizjologiczne wskazują, że lęki nocne występują podczas przejścia ze snu głębokiego do lżejszych faz snu. W tym czasie osoba znajduje się w stanie częściowego wybudzenia, gdzie obszar mózgu odpowiedzialny za reakcje „walcz lub uciekaj” staje się nadmiernie pobudzony, co wywołuje uczucie paniki i przerażenia.⁵⁷

Obrazowanie mózgu za pomocą badania SPECT (tomografia emisyjna pojedynczego fotonu) u pacjentów z parasomnią wykazało aktywację szlaku wzgórzowo-kręgowego przy jednoczesnej utrzymującej się dezaktywacji w szlaku wzgórzowo-korowym odpowiedzialnym za wybudzanie.³ Badania EEG wskazują, że przed epizodem lęku nocnego można zaobserwować aktywność wysokonapięciowych fal wolnych, a podczas epizodu EEG może pokazywać rozlane, hipersynchroniczne rytmiczne fale delta, rozlane fale delta z przemieszanymi szybszymi częstotliwościami w zakresie theta i alfa lub wyraźną aktywność alfa i beta.⁸

Dysregulacja neuroprzekaźników

Nie zidentyfikowano spójnej przyczyny lęków nocnych. W mózgu nie stwierdzono żadnych specyficznych nieprawidłowości biochemicznych ani strukturalnych.¹² Jednak badania sugerują, że dysfunkcja w układzie serotoninergicznym może odgrywać rolę w patogenezie lęków nocnych.³

Zasugerowano, że poziomy serotoniny lub jej prekursora mogą być powiązane z występowaniem lęków nocnych. Dowody wskazują, że L-5-hydroksytryptofan (prekursor serotoniny) oraz inhibitory zwrotnego wychwytu serotoniny, takie jak paroksetyna, mogą pomóc zmniejszyć częstotliwość występowania lęków nocnych.³⁹

Mechanizm działania leków SSRI (selektywne inhibitory zwrotnego wychwytu serotoniny) w lękach nocnych jest złożony i nie został jeszcze w pełni wyjaśniony. Leki te wpływają na poziom neuroprzekaźników w mózgu, takich jak serotonina i norepinefryna, które odgrywają kluczową rolę w regulacji cyklu snu i czuwania.¹⁰

Rola wzgórza i kory mózgowej

W niektórych przypadkach uszkodzenie lub dysfunkcja wzgórza zostały powiązane z lękami nocnymi.¹¹ Wzgórze odgrywa kluczową rolę w utrzymywaniu cykli snu i czuwania, a jego nieprawidłowe funkcjonowanie może przyczyniać się do występowania lęków nocnych.

Badacze sugerują, że osoby doświadczające lęków nocnych mogą mieć trudności z utrzymaniem snu wolnofalowego, co czyni je podatnymi na nagłe wybudzenia i zwiększa ryzyko wystąpienia parasomnii.¹¹

Istnieją również dowody sugerujące, że niektóre obwody hamujące GABAergiczne i cholinergiczne w korze mózgowej mogą być niedojrzałe lub nieefektywne w hamowaniu ruchów podczas snu, co przyczynia się do występowania lęków nocnych.⁸

Czynniki wywołujące lęki nocne

Predyspozycje genetyczne

Istnieje silny związek rodzinny w występowaniu lęków nocnych. Badania wykazują, że osoby, których rodzice doświadczali epizodów chodzenia przez sen, są bardziej narażone na występowanie lęków nocnych, które mogą również utrzymywać się dłużej.¹²¹³

Predyspozycja do lęków nocnych i innych parasomnii może być wrodzona, co sugeruje silny komponent genetyczny.⁴¹⁴ Badania pokazują, że osoby z lękami nocnymi często mają członka rodziny, który również doświadcza lęków nocnych lub chodzenia przez sen, co wskazuje na wspólną silną predyspozycję genetyczną.¹⁵¹⁶

Zaobserwowano również związek między lękami nocnymi i chodzeniem przez sen w rodzinach osób z nocną padaczką płata czołowego, co sugeruje wspólne podłoże genetyczne tych zaburzeń.¹⁵

Zaburzenia snu i choroby współistniejące

Lęki nocne mogą być wywołane przez inne zaburzenia snu, które zakłócają normalny cykl snu:¹⁷

Zaburzenia oddychania podczas snu, w tym obturacyjny bezdech senny¹⁷¹⁸
Zespół niespokojnych nóg¹⁷¹⁹
Padaczka¹⁸²⁰
Refluks żołądkowo-przełykowy¹⁸²¹

Lęki nocne występują częściej u dzieci z zaburzeniami oddychania podczas snu niż u dzieci zdrowych i są częstsze u pacjentów z obturacyjnym bezdechem sennym.⁸ W niektórych przypadkach lęki nocne mogą być objawem wywołanym przez problemy medyczne, w tym zaburzenia snu REM, napady padaczkowe lub zaburzenia ruchu.¹⁴

Czynniki środowiskowe i psychologiczne

Liczne czynniki mogą przyczyniać się do występowania lęków nocnych lub zwiększać ryzyko ich wystąpienia:¹⁷⁴

Poważny brak snu i skrajne zmęczenie¹⁷¹³
Stres i napięcie emocjonalne¹⁷¹⁸
Zmiany harmonogramu snu, podróże lub przerwy w śnie¹⁷²²
Gorączka i choroby¹⁷²³
Trauma psychiczna²⁴²⁵

U dorosłych lęki nocne mogą być związane z zaburzeniami nastroju, takimi jak depresja i zaburzenia lękowe.¹⁷²⁶ Badania wykazały, że dorośli z lękami nocnymi częściej mają historię zaburzeń afektywnych dwubiegunowych, depresyjnych lub lękowych.²⁶

Wpływ leków i substancji

Niektóre leki i substancje mogą wpływać na występowanie lęków nocnych:¹⁷²⁶

Leki przeciwhistaminowe²⁷
Leki przeciwdepresyjne²⁷
Benzodiazepiny²²
Trójpierścieniowe leki przeciwdepresyjne²²
Alkohol¹⁷²⁶
Kofeina²²

Leki, które zwiększają ilość snu w fazach 3 i 4, takie jak benzodiazepiny czy trójpierścieniowe leki przeciwdepresyjne, mogą potencjalnie zwiększać ryzyko wystąpienia lęków nocnych.²² Z drugiej strony, niektóre leki są stosowane w leczeniu lęków nocnych, w tym benzodiazepiny, selektywne inhibitory zwrotnego wychwytu serotoniny (SSRI) i trójpierścieniowe leki przeciwdepresyjne.²⁴

Mechanizm fizjologiczny lęków nocnych

Odpowiedź autonomicznego układu nerwowego

Lęki nocne wiążą się z intensywnym wyładowaniem autonomicznym, charakteryzującym się:⁴²⁸

Tachypnoe (przyspieszony oddech)⁴
Zaczerwienieniem skóry⁴
Nadmiernym poceniem się (diaphoresis)⁴
Rozszerzeniem źrenic (mydriasis)⁴
Tachykardią (przyspieszone bicie serca)²⁸
Drżeniem²⁹

Podczas epizodu lęku nocnego następuje aktywacja układu współczulnego, co prowadzi do fizjologicznej reakcji „walcz lub uciekaj”. Osoby doświadczające lęku nocnego mogą wykazywać oznaki intensywnego stresu, takie jak krzyk, płacz i gwałtowne ruchy kończyn.³⁰

Zmiany w aktywności mózgu podczas lęków nocnych

Badania EEG (elektroencefalograficzne) podczas lęków nocnych sugerują, że moc delta i synchronizacja w EEG mogą być ważnymi markerami fizjologicznymi obecności i intensywności lęku nocnego.³¹ Mapy aktywności mózgu wykazały, że podczas epizodów lęku nocnego występuje większa całkowita moc i moc delta w obszarach centralnych i czołowych w porównaniu z kontrolnymi odcinkami EEG.³¹

Co ciekawe, względna moc delta w tych obszarach dla trzech badanych epizodów lęku nocnego była proporcjonalna do subiektywnej intensywności epizodu.³¹ Wzorzec EEG przed wybudzeniem może być związany z trwającą aktywnością mentalną podczas snu wolnofalowego, która może czasami wyzwalać epizody lęku nocnego.³¹

Nieprawidłowa regulacja faz snu

Lęki nocne klasyfikuje się jako zaburzenie wybudzania, opierając się na koncepcji, że zaburzenia mechanizmów wybudzania prowadzą do aktywacji behawioralnej i emocjonalnej, ale nie do pełnego wybudzenia.¹⁶ Podczas epizodu lęku nocnego osoba znajduje się w stanie częściowego wybudzenia, ale nie jest w pełni obudzona.¹⁷

Osoby z lękami nocnymi mogą mieć nieprawidłowo zsynchronizowane fale mózgowe podczas głębokiej fazy snu. Gdy fale mózgowe zderzają się ze sobą, mogą wprowadzić osobę w stan półprzytomności. Ciało może przejść z stanu spoczynku do pełnej aktywacji, powodując przyspieszenie akcji serca i napięcie mięśni, ale świadomość pozostaje wyłączona i nie jest świadoma tego, co się dzieje.⁷

Ten mechanizm wyjaśnia, dlaczego osoby doświadczające lęków nocnych zazwyczaj nie pamiętają epizodu następnego dnia.³²³³

Mechanizmy rozwojowe lęków nocnych

Dojrzewanie układu nerwowego

Lęki nocne są częstsze u dzieci i młodzieży, co sugeruje związek z dojrzewaniem układu nerwowego.²¹³ Uważa się, że są one spowodowane niedojrzałym mózgiem, dlatego stan ten zazwyczaj ustępuje wraz z dojrzewaniem mózgu dziecka, zwykle do wieku sześciu lat.³⁴³⁵

Sen jest złożonym procesem mózgowym i fizjologicznym, a lęki nocne są uważane za nieprawidłowe funkcjonowanie normalnego cyklu snu, które występuje, ponieważ mózg dziecka nie jest jeszcze w pełni rozwinięty.³⁵ Wraz z dojrzewaniem mózgu dziecka, zdolność do płynnego przechodzenia między fazami snu zazwyczaj się poprawia, co prowadzi do zmniejszenia częstotliwości lęków nocnych.²⁷

Nadmierne pobudzenie ośrodkowego układu nerwowego

Lęki nocne często występują podczas przejścia z głębokiego snu non-REM do czuwania. W tym momencie, jeśli ośrodkowy układ nerwowy (OUN) zostanie nadmiernie pobudzony podczas tego przejścia, może to prowadzić do epizodu lęku nocnego.³⁶

Podczas lęku nocnego organizm przechodzi reakcję stresową, ale mózg nadal znajduje się w głębokim śnie.³⁶ Badacze sugerują, że najbardziej pomijaną przyczyną i czynnikiem wyzwalającym lęki nocne u małych dzieci jest nadmiernie pobudzony i nadaktywny współczulny układ nerwowy „walcz lub uciekaj”.³⁷

Wiele dzieci zmagających się z takimi stanami jak Zaburzenia Przetwarzania Sensorycznego, Autyzm i ADHD ma podstawowe zaburzenia znane jako Dysautonomia i Subluksacja, które prowadzą do trwającej nierównowagi neurologicznej i dysfunkcji, co może przyczyniać się do zwiększonej częstotliwości i nasilenia lęków nocnych.³⁷

Związek z innymi zaburzeniami neurosensorycznymi

Chociaż większość pediatrów i lekarzy nadal informuje rodziców, że lęki nocne u małych dzieci są nieszkodliwe i dziecko z czasem z nich „wyrośnie”, obserwacje kliniczne pokazują, że dzieci, które doświadczyły wysokiego stopnia lęków nocnych i problemów ze snem we wczesnym okresie życia, zaczynają później borykać się z takimi problemami jak Zaburzenia Przetwarzania Sensorycznego, ADHD i lęki.³⁸

Istnieje potencjalny związek i korelacja między tym konkretnym wyzwaniem a innymi stanami neurosensorycznymi i zaburzeniami snu w późniejszym życiu.³⁸ Zrozumienie i leczenie podstawowej przyczyny lęków nocnych w formacyjnych latach może pomóc złagodzić potencjalne długoterminowe konsekwencje.³⁹

Różnice między lękami nocnymi a koszmarami

Lęki nocne są często mylone z koszmarami sennymi, ale są to zupełnie różne zjawiska z odmiennymi mechanizmami neurofizjologicznymi.²²

Cecha	Lęki nocne (parasomnia)	Koszmary senne
Faza snu	Występują podczas snu non-REM (fazy 3-4)	Występują podczas snu REM
Czas wystąpienia	Pierwsza 1/3 nocy (1-3 godziny po zaśnięciu)	Druga połowa nocy
Stan świadomości	Osoba jest częściowo wybudzona, ale nie w pełni przytomna	Osoba budzi się całkowicie
Pamięć zdarzenia	Brak pamięci epizodu następnego dnia	Pełna pamięć koszmaru
Reakcja na pocieszenie	Trudności w uspokojeniu, brak reakcji na pocieszenie	Możliwość uspokojenia po przebudzeniu
Objawy fizjologiczne	Silna aktywacja układu autonomicznego (pocenie, tachykardia, rozszerzone źrenice)	Mniej intensywne objawy fizjologiczne
Zachowanie	Krzyk, płacz, gwałtowne ruchy, czasem chodzenie	Płacz, strach, ale mniej gwałtowne zachowania

Podczas lęku nocnego mózg jest częściowo wybudzony z głębokiego snu non-REM, ale nie jest w pełni przytomny. Osoba może mieć otwarte oczy, mówić, krzyczeć, ale nie reaguje na próby pocieszenia.⁴⁰ W przeciwieństwie do tego, koszmary senne występują podczas snu REM, kiedy osoba śni, a po przebudzeniu z koszmaru jest w pełni świadoma i może natychmiast przypomnieć sobie przerażający sen.⁴¹

Lęki nocne wiążą się z częściowym wybudzeniem z non-REM snu, podczas gdy osoba nie śni, podczas gdy koszmary występują podczas fazy REM, kiedy marzenia senne są najczęstsze.²⁷ Podczas fazy REM osoby nie są w stanie się poruszać, krzyczeć ani mówić, co wyjaśnia różnice w zachowaniu między tymi dwoma zjawiskami.²⁷

Rola czynników genetycznych w lękach nocnych

Badania genetyczne wykazują silny związek rodzinny w występowaniu lęków nocnych, co sugeruje istotny komponent dziedziczny.¹⁵¹²

Dziedziczenie lęków nocnych

Lęki nocne są zaburzeniem dziedzicznym, co oznacza, że dziecko może otrzymać tę skłonność od swoich rodziców.¹⁴ Badania wykazały, że jeśli u rodzica występowały epizody chodzenia przez sen, jego dziecko jest bardziej narażone na występowanie lęków nocnych.¹²

Obserwacje kliniczne wskazują, że jeśli jeden z członków rodziny cierpi na lęki nocne, istnieje zwiększone ryzyko (80-90%), że również dziecko będzie doświadczać lęków nocnych.⁴² Badania genetyczne wykazały, że allel HLA-DQB1*05:01 występuje częściej u osób z lękami nocnymi.⁴³

Związek z innymi zaburzeniami snu

Istnieje silna korelacja między lękami nocnymi a chodzeniem przez sen, z wysoką częstotliwością występowania jednego lub drugiego procesu u członków rodziny pierwszego stopnia osób doświadczających lęków nocnych.¹⁵

Jeśli osoba doświadcza lęków nocnych, istnieje 96% szans, że członek rodziny również doświadcza podobnych problemów. Mogą to być lęki nocne, epizody chodzenia przez sen lub oba te zaburzenia.⁴³

Ponadto, zgłoszono związek lęków nocnych i chodzenia przez sen u członków rodzin osób z nocną padaczką płata czołowego, co sugeruje wspólne podłoże genetyczne tych zaburzeń.¹⁵

Genetyczne markery ryzyka

Badania genetyczne wykazały, że istnieje wyraźny dowód na to, że wiele osób z lękami nocnymi ma rodzinną historię lęków nocnych, chodzenia przez sen lub obu tych zaburzeń, co potwierdza hipotezę, że chodzenie przez sen i lęki nocne mają wspólną silną predyspozycję genetyczną.¹⁶

Zidentyfikowano szereg genetycznych, rozwojowych, psychologicznych i organicznych czynników ryzyka dla lęków nocnych.¹⁶ Istnieje również stronny komponent genetyczny, co oznacza, że lęki nocne mogą być dziedziczone od rodziców i występować w rodzinach.⁴⁴

Te obserwacje genetyczne mogą w przyszłości pomóc w opracowaniu bardziej ukierunkowanych metod leczenia i identyfikacji osób z podwyższonym ryzykiem wystąpienia lęków nocnych.

Night terrors are a common sleep disorder in young children and describe a condition in which a child wakes up from sleep in a terrified state. A night terror is considered a parasomnia due to its characterization of unusual physical and verbal behaviors. […] Night terrors specifically are associated with non-rapid eye movement (REM) sleep stages in which the person or child is in a transitional state between sleep and wakefulness. […] No consistent reason to explain night terror is available. No biochemical or structural abnormality is found in the brain. It has been suggested that levels of serotonin or its precursor may be linked. Thus, SSRIs are often prescribed for night terrors. There is a strong association between sleepwalking and night terrors; in addition, there is a high familial risk.

https://emedicine.medscape.com/article/914360-overview
Sleep terrors (also referred to as night terrors) are a specific sleep disruption most remarkable for their intensity and anxiety-inducing nature. Several precipitating factors have been suggested, but no consistent structural or biochemical abnormality has been identified to account for all cases of sleep terrors. […] A dysfunction in the serotoninergic system has been suggested, owing to an association found between adolescents with migraines and a history of sleep terrors. Additionally, some evidence has suggested that the serotonin precursor L-5-hydroxytryptophan and the serotonin reuptake inhibitor paroxetine can help reduce the frequency of sleep terrors. […] Sleep studies demonstrate that sleep terrors occur during stages 3 and 4 of nonREM (NREM) sleep. Data from a single-proton emission computed tomography (SPECT) scan in a patient with parasomnia show there was activation of the thalamocingulate pathway with persistent deactivation in the thalamocortical arousal pathway.
#4 Night terror – Wikipedia
https://en.wikipedia.org/wiki/Night_terror
Night terror, also called sleep terror, is a sleep disorder causing feelings of panic or dread and typically occurring during the first hours of stage 34 non-rapid eye movement (NREM) sleep and lasting for 1 to 10 minutes. […] Sleep terrors usually begin in childhood and usually decrease as age increases. Factors that may lead to sleep terrors are young age, sleep deprivation, medications, stress, fever, and intrinsic sleep disorders. […] Night terrors tend to happen during periods of arousal from delta sleep, or slow-wave sleep. […] Night terrors are also associated with intense autonomic discharge of tachypnea, flushing, diaphoresis, and mydriasisâthat is, unconscious or involuntary rapid breathing, reddening of the skin, profuse sweating, and dilation of the pupils. […] There is some evidence that a predisposition to night terrors and other parasomnias may be congenital. […] Some laboratory findings suggest that sleep deprivation and having a fever can increase the likelihood of a night terror episode occurring. […] Though the symptoms of night terrors in adolescents and adults are similar, their causes, prognoses, and treatments are qualitatively different.
#5 Night Terrors (for Parents) | Nemours KidsHealth
https://kidshealth.org/en/parents/terrors.html
A night terror (also called sleep terror) is similar to a nightmare, but is far more dramatic. […] Night terrors usually happen about 23 hours after a child falls asleep. This is when the brain is in non-REM (non-rapid eye movement) stages of sleep. The child partly wakes up, and the area of the brain that controls fight-or-flight responses becomes overexcited. This makes the child feel panicked and terrified. […] Because they happen when a child is partially awake, things that disturb sleep can make night terrors more likely (such as obstructive sleep apnea and reflux). […] Night terrors and other sleep disturbances, such as sleepwalking, often run in families.

During Rhazes’ time, research shows that mater puerorum have been used to describe both epileptic attacks and night terrors. […] Classically, night terrors arise during the first sleep cycle, usually within 1-3 hours of sleep. […] Night terrors are fascinating entities that share many of the same characteristics of the other parasomnias occurring as arousals from non-rapid eye movement (NREM) sleep.
#7 Night Terrors vs. Nightmares: Signs, Causes, Tips to Cope
https://www.healthline.com/health/sleep/night-terrors-vs-nightmares
Night terrors, also called sleep terrors, are episodes where you partially awake from slow-wave sleep. They generally involve signs of extreme stress, like screaming or waving your limbs. You probably wont remember them, but a broken lamp or a concerned roommate may clue you in to what happened. […] Night terrors typically happen when youre deeply asleep. This period is called slow-wave sleep since the waves of electrical activity in your brain are larger and slower than usual. […] People with frequent night terrors tend to have mismatched brain waves during this phase of sleep. When the brain waves clash, they may throw you into a half-awake state. Your body can go from zero to 100, making your heart race and your muscles tense. But your conscious self will likely be offline and unaware of whats going on.
#8 Sleep terror | MedLink Neurology
https://www.medlink.com/articles/sleep-terror
An immature form of some cortical GABAergic and cholinergic inhibitory circuits might be ineffective in stopping movements during sleep. […] Sleep terrors occur more often in children with sleep-disordered breathing than in normal children and are increased in patients with obstructive sleep apnea. […] High-voltage slow-wave activity may be seen immediately prior to the episode, and the EEG during an episode may show diffuse, hypersynchronous rhythmic delta, diffuse delta with intermixed faster frequencies in the theta and alpha range, or prominent alpha and beta activity.
#9 6 Medications That Can Cause Night Terrors in Adults – BuzzRx
https://www.buzzrx.com/blog/6-medications-that-can-cause-night-terrors-in-adults
Have you ever woken up in the middle of the night drenched in sweat with your heart pounding? This baffling phenomenon is known as night terrors, or sleep terrors, a type of parasomnia that typically occurs during the deepest stage of the non-rapid eye movement sleep (NREM). Night terrors are characterized by sudden awakenings at night and are accompanied by intense fear and confusion. […] Various factors can trigger the occurrence of night terrors, including certain medications. Night terrors are common in children but can also affect adults. […] In this article, weâll explore the medications that can cause sleep terror in adults. We will also learn the mechanisms and factors associated with causing nightmares. […] It is essential to know that serotonin plays a significant role here. However, the mechanism by which SSRIs cause sleep terrors and nightmares is incredibly complex and has yet to be fully understood. More research is essential to learn about the relationship between SSRIs and sleep side effects.
#10 6 Medications That Can Cause Night Terrors in Adults – BuzzRx
https://www.buzzrx.com/blog/6-medications-that-can-cause-night-terrors-in-adults
The mechanism behind this is that they can affect neurotransmitter levels in the brain, such as serotonin and norepinephrine. […] It is important to understand why and how medications can trigger night terrors. Some of the reasons are: […] Certain medications are designed to target neurotransmitter levels in the brain to treat certain health conditions. However, due to the complexity of these brain chemicals, imbalance of certain brain chemicals and hormones can lead to nightmares or sleep terrors. […] Selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and tricyclic antidepressants (TCAs) work by changing the levels of neurotransmitters or brain chemicals in the nervous system. An imbalance of serotonin and norepinephrine levels can disrupt sleep patterns and may lead to sleep disturbances, including sleep terrors. […] Sleep aids that help with falling asleep and drugs used to treat sleep disorders can disrupt the structure and stages of sleep. For example, medications promoting rapid eye movement sleep (REM) can increase the chances of adult night terrors.
#11 Night terrors: Causes, symptoms, and treatment
https://www.medicalnewstoday.com/articles/301893
Night terrors, or sleep terrors, are common terms for episodes that cause fear at night, especially in children. […] Night terrors occur during the first third of the night during deeper sleep, also known as slow-wave sleep or non-REM sleep. […] Night terrors and sleepwalking appear to be linked. They both occur during slow-wave sleep, the deepest sleep stages, that happen in the early part of the night. […] Some researchers believe that people who experience sleepwalking or night terrors may have difficulty in maintaining slow-wave sleep. This makes them susceptible to quick arousals, and it increases the chance of parasomnias. […] In some cases, however, damage to or dysfunction of the thalamus has been linked to this phenomenon. […] The thalamus is thought to play a key role in maintaining sleep-wake cycles.
#12 Night terrors: Causes, symptoms, and treatment
https://www.medicalnewstoday.com/articles/301893
People who have night terrors or who sleep walk often have a family member who also does this. […] A long-term study of 1,940 children, published in 2015, found that those whose parents had walked in their sleep were more likely to have night terrors and that these night terrors were more likely to persist for longer.
#13 Night Terrors: What They Are, Causes, Symptoms & Treatment
https://my.clevelandclinic.org/health/diseases/night-terrors
Night terrors (sleep terrors) happen when your brain is partially asleep and partially awake. It causes a state of panic or fear. […] The cause of night terrors is unknown. Research suggests night terrors happen when your consciousness is stuck between deep stages of sleep and wakefulness. […] Night terrors may trigger (happen) after or because of the following: Having a fever. Sleep deprivation. Obstructive sleep apnea. Feeling stress or anxiety. Emotional tension. Drinking alcohol. […] Night terrors can affect anyone at any age. Studies show that night terrors may run in your biological family history. […] Night terrors usually dont last forever. Many children may outgrow night terrors before they reach high school. Some night terrors happen with underlying conditions, so managing those can reduce how often night terrors happen.
#14 Night Terrors In Children | Children’s Hospital Colorado
https://www.childrenscolorado.org/conditions-and-advice/conditions-and-symptoms/conditions/night-terrors/
Night terrors are an inherited disorder in which a child tends to have dreams during deep sleep from which it is difficult to awaken. […] Night terrors are inherited, meaning a child gets the disorder from his or her parents and the condition runs in families. […] Sometimes, recurring night terrors are a symptom of other sleep disorders like obstructive sleep apnea. […] Night terrors are rarely, but sometimes, a symptom triggered by medical problems, including a disorder of dream sleep, a seizure or a movement disorder.
#15 Sleep Terrors: Practice Essentials, Background, Pathophysiology
https://emedicine.medscape.com/article/914360-overview
A strong correlation between sleep terrors and sleepwalking is noted, with a high frequency of either process in first-degree family members of individuals who experience sleep terrors. An association of sleep terrors and sleepwalking in family members of individuals with nocturnal frontal lobe epilepsy has also been reported.
#16 Sleep terror | MedLink Neurology
https://www.medlink.com/articles/sleep-terror
Sleep terror is one of the manifestations of disorders of arousal and consists of abrupt arousals out of sleep stage 3 NREM, primarily in the first third of the night, with disordered motor agitation, screaming, fear, and autonomic activation. […] The pathogenesis of sleep terrors is unknown. Sleep terror is classified as a disorder of arousal based on the concept that disordered arousal mechanisms lead to behavioral and emotional activation but not to a full awakening. […] A number of genetic, developmental, psychological, and organic risk factors have been identified for sleep terrors. […] There is clear evidence that many patients with sleep terrors have a family history of sleep terrors, sleepwalking, or both, supporting the hypothesis that sleepwalking and night terrors share a common strong genetic predisposition.
#17 Sleep terrors (night terrors) – Symptoms and causes – Mayo Clinic
https://www.mayoclinic.org/diseases-conditions/sleep-terrors/symptoms-causes/syc-20353524
Sleep terrors are a type of parasomnia. A parasomnia is a disturbing or strange behavior or experience during sleep. People who have sleep terrors don’t completely wake up from sleep during the episodes. Their appearance may suggest they are awake, but they remain partially asleep. […] Several issues can contribute to sleep terrors, such as: Serious lack of sleep and extreme tiredness. Stress. Sleep schedule changes, travel or sleep interruptions. Fever. […] Sleep terrors sometimes can be triggered by conditions that interfere with sleep, such as: Sleep-disordered breathing a group of disorders that include breathing patterns that are not typical during sleep. The most common type of sleep-disordered breathing is obstructive sleep apnea. Restless legs syndrome. Some medicines. Mood disorders, such as depression and anxiety. Alcohol use.
#18 Sleep/Night Terrors | Sleep Health Foundation
