Nocturnal seizures and the effects of anticonvulsants on sleep.

Epilepsy is a common condition that affects up to 1% of the population. Patients with epilepsy are particularly sensitive to the adverse effects of sleep disruption. Failure to recognize and treat sleep disturbances can lead to worsening of attention, cognitive functioning, and quality of life, and can increase seizures. Anticonvulsant agents have the potential to either improve or worsen sleep and sleep disorders in patients with epilepsy. Therefore, awareness of the implications of sleep disorders and anticonvulsants is critical for the optimal care of patients with epilepsy.
