How does sleep deprivation affect seizure risk in pediatric epilepsy?

• A. Only affects adults
• B. Decreases seizure frequency
• C. Lowers seizure threshold and increases seizure likelihood
• D. Has no effect

Answer: (C)

Sleep deprivation lowers seizure threshold and increases seizure likelihood. In children with epilepsy, getting enough sleep helps stabilize brain networks, while missing sleep makes the brain more excitable and less capable of controlling abnormal electrical activity. This can manifest as more frequent seizures or seizures triggered by wakefulness, especially during transitions between sleep and wakefulness. The mechanisms involve heightened cortical excitability, reduced inhibitory control, and shifts in neurotransmitter balance that favor seizure activity, along with disruption of normal sleep architecture that can promote epileptiform discharges.

Regular, adequate sleep is an important part of managing pediatric epilepsy, and clinicians often emphasize good sleep hygiene and consistent bedtime routines to help reduce seizure risk. This effect is not limited to adults; sleep loss can provoke seizures in children too, and it does not decrease seizure frequency or have no effect.
