Understanding the Mutual Relationship Between Sleep Apnea and Seizures That Worsen Each Other

Sleep apnea and seizures share a closer relationship than many people realize. A study from the Neurology Journal published by the American Academy of Neurology shows that sleep apnea can trigger or worsen seizures — particularly in people with epilepsy — and conversely, uncontrolled seizures can further disrupt sleep.

How Do Sleep Apnea and Seizures Worsen Each Other?

Sleep apnea can worsen seizures through four main mechanisms:

1. Chronic sleep deprivation caused by frequent nighttime awakenings, which lowers the seizure threshold
2. Disrupted sleep stages — patients spend more time in light sleep, whereas deep sleep is essential for neurological stability
3. Reduced oxygen supply to the brain due to repeatedly interrupted breathing
4. Cardiovascular problems such as poor blood flow or an irregular heartbeat, which affect brain function

Can Seizures Occur During Sleep?

Yes — approximately 10–15% of epilepsy cases are closely associated with sleep. Some individuals experience sleep-related seizures or even mini seizures that are so mild they go unnoticed. Mini seizures most commonly occur during light sleep stages, when the brain is transitioning between sleep and wakefulness.

Sleep Apnea Symptoms to Watch Out For

Early detection of symptoms is crucial, especially for those with epilepsy or a history of seizures:

• Consistently loud snoring during sleep
• Interrupted breathing, choking, or gasping during sleep
• Frequent nighttime awakenings without a clear reason
• Headaches upon waking in the morning
• Body mass index above 30 (obesity)

The Right Diagnostic Approach

To confirm the relationship between seizures and sleep disorders, doctors typically perform:

1. Evaluation of symptoms and a complete medical history
2. Physical examination, including assessment of the airway structure
3. Brain activity testing (EEG) or imaging if necessary
4. Sleep study overnight to accurately measure the apnea-hypopnea index

Comprehensive Treatment for Optimal Results

With proper sleep apnea treatment — most commonly CPAP therapy — sleep quality can improve significantly, and the frequency and intensity of seizures in epilepsy patients can be reduced.
