Rem Sleep Deprivation: A Trigger For Morning Seizures?

can morning seizures be due to lack of rem sleep

Sleep and epilepsy are closely linked. Sleep deprivation can trigger seizures in people with epilepsy, and seizures can disrupt sleep. Nocturnal seizures, which occur during sleep, are often unnoticed but can cause interrupted sleep, leaving the person feeling tired during the day. Morning seizures can be caused by a lack of REM sleep, as sleep deprivation can increase abnormal electrical activity in the brain.

Sleep deprivation can increase the risk of seizures

Sleep is essential for everyone, and it is particularly important for people with epilepsy. Sleep deprivation can increase the risk of seizures in people with epilepsy, and it can even increase the intensity and length of seizures. The relationship between sleep and epilepsy is complex and varies from person to person. However, it is clear that sleep deprivation can be a significant trigger for seizures in some individuals.

During sleep, our brains undergo changes in electrical and hormonal activity. Sleep deprivation can disrupt these normal brain functions, leading to an increase in abnormal electrical activity, which may trigger seizures. This is particularly true for people with epilepsy, as they are already prone to abnormal electrical activity in the brain. Sleep deprivation can further heighten this abnormal activity, making seizures more likely to occur.

The impact of sleep deprivation on seizures may be influenced by various factors, such as the quality and quantity of sleep, the presence of other triggers, and individual differences in sleep needs. Some people may experience seizures only when they are sleep-deprived, while for others, sleep deprivation may be one of several factors that contribute to seizure activity. Additionally, the effects of sleep deprivation on seizures may be more pronounced in people with certain types of epilepsy.

It is worth noting that the direction of the relationship between sleep and epilepsy is bidirectional. While sleep deprivation can trigger seizures, having seizures at night can also disrupt sleep quality. This creates a cycle where seizures worsen sleep, and poor sleep, in turn, increases the likelihood of seizures. As a result, people with epilepsy may experience chronic sleep deprivation and subsequent increases in seizure activity.

To manage epilepsy effectively, it is crucial for individuals to prioritise getting sufficient, high-quality sleep. This may involve maintaining a consistent sleep schedule, improving sleep habits, and treating any underlying sleep disorders. By optimising sleep, people with epilepsy may be able to reduce the frequency and severity of their seizures.

Sleep disorders, such as insomnia and sleep apnea, can affect epilepsy

Sleep and epilepsy have a complex relationship. Nocturnal seizures can occur when a person is sleeping, specifically:

  • Right after falling asleep
  • Just before waking up
  • Soon after waking up

Any seizure can occur during sleep, but certain conditions are more likely to experience nocturnal seizures, including:

  • Juvenile myoclonic epilepsy
  • Awakening tonic-clonic (grand mal)
  • Landau-Kleffner syndrome
  • Frontal lobe epilepsy

The links between epilepsy and sleep are complex. For some people, a lack of sleep can make seizures more likely to happen, while for others, having seizures at night can make them feel tired during the day. Sleep disorders, such as insomnia and sleep apnea, can affect epilepsy, and epilepsy can also affect sleep disorders.

Insomnia

Insomnia is a sleep disorder characterised by difficulty falling asleep, difficulty staying asleep, or both. Insomnia can be caused by depression and anxiety, which are more common in people with epilepsy. It can also be caused by seizures, moods, and medicine side effects.

Sleep Apnea

Obstructive sleep apnea (OSA) is a common sleep disorder characterised by repetitive episodes of complete or partial airway obstruction. It is probably present in at least 3% of the general population but has been reported in up to 40% of middle-aged men. OSA can be more common in people with epilepsy, with one study finding it in 71% of people with epilepsy who were referred for a sleep study.

OSA can be treated with continuous positive airway pressure (CPAP), oral appliances for repositioning the airway, surgery, and conservative treatments such as sleep positioning and weight loss.

Other Sleep Disorders

Other sleep disorders that can affect people with epilepsy include:

  • Narcolepsy: A rare condition causing uncontrollable urges to fall asleep, which also disrupts overnight sleep.
  • Insufficient sleep syndrome: This is characterised by excessive daytime sleepiness and frequent awakenings.
  • Periodic limb movements: This involves repetitive cycles of rhythmic movements, usually in the legs, that can wake people up and cause daytime drowsiness.
  • Nocturnal seizures: Seizures that occur during sleep.

In summary, sleep disorders such as insomnia and sleep apnea can affect epilepsy, and epilepsy can also affect sleep disorders. Sleep disorders are common in people with epilepsy and can impact their treatment and management. Therefore, screening, evaluation, and treatment for sleep disorders should be a part of care for patients with epilepsy.

Lack of REM sleep can impact memory and concentration

Sleep is essential for everyone, but especially for those with epilepsy. Research suggests that getting a good night's sleep and dreaming help our brains create meaning from the day's experiences and strengthen our memories. Sleep can affect seizures in many different ways. During normal sleep-wake cycles, changes in the brain's electrical and hormonal activity occur, which may be related to why some people have more seizures during sleep than others, and why not getting enough sleep can trigger seizures.

Sleep deprivation can disrupt the normal functioning of the brain, leading to an increase in abnormal electrical activity that can trigger seizures. This is supported by a study that found that 43% of participants with epilepsy had clinically significant insomnia, which was associated with poor short-term seizure control and a worsened quality of life.

Additionally, seizures during sleep can disrupt sleep patterns for the rest of the night, reducing REM sleep and impacting memory and concentration. It is important for people with epilepsy to get enough high-quality sleep to help manage their condition.

Nocturnal seizures are often unnoticed but can be identified through certain signs

Nocturnal seizures, or seizures during sleep, are often unnoticed as the patient is asleep when they happen. However, there are certain signs that may suggest a person is experiencing nocturnal seizures.

Nocturnal seizures are most common right after falling asleep, just before waking up, or soon after waking up. They can occur during any sleep stage but are most frequent during the early morning, between 5 a.m. and 6 a.m., and least often shortly after falling asleep. Nocturnal seizures can be triggered by changes in the electrical activity in the brain during certain sleep stages.

Signs that may indicate nocturnal seizures include interrupted sleep patterns, such as difficulty concentrating, awaking suddenly for unknown reasons, and an increase in daytime seizures. Involuntary muscle movements during sleep, such as jerking body movements, tongue biting, or strange postures, can also be indicative of nocturnal seizures. Additionally, loss of bladder control and bed wetting may be signs of nocturnal seizures.

In children, nocturnal seizures can be particularly challenging to recognise. Signs to look for include muscle twitches or jerks, trouble waking after a seizure, and strange movements or postures while sleeping. Monitoring devices, such as baby monitors or seizure monitors, can be helpful in detecting nocturnal seizures in infants and young children.

If you suspect that you or someone you know is experiencing nocturnal seizures, it is important to consult a doctor. They can perform tests, such as an electroencephalogram (EEG) or imaging scans, to confirm the diagnosis and determine the best treatment approach.

Anti-seizure medications can cause side effects like tiredness and insomnia

Seizures are very sensitive to sleep patterns. A lack of sleep can make seizures more likely to happen, and having seizures at night can make people feel tired during the day. Sleep disorders, such as insomnia and obstructive sleep apnoea (OSA), can affect epilepsy, and epilepsy can also affect sleep disorders.

Anti-seizure medications (ASMs) can cause side effects such as tiredness and insomnia. The effects of ASMs on sleep vary from person to person, depending on the dose and the specific medication. Some ASMs are classed as sedatives and can cause tiredness, while others can cause insomnia or disrupted sleep. For example, clonazepam, a benzodiazepine tranquilizer, is known to cause drowsiness. Other medications, such as carbamazepine (Carbatrol or Tegretol), can cause insomnia, dizziness, fatigue, diplopia, and headaches.

It is important to note that while some ASMs may disrupt sleep, others can help improve sleep quality by increasing the length of deep sleep. For instance, gabapentin has been found to enhance slow-wave sleep in patients with epilepsy and increase sleep continuity, resulting in fewer awakenings. Additionally, it may be useful in treating restless leg syndrome, a common sleep disorder.

The impact of ASMs on sleep is a crucial consideration in treatment decisions, especially for patients with comorbid sleep disorders. Clinicians should carefully evaluate the potential benefits and drawbacks of different medications to determine the most suitable option for each patient.
