[The impact of antiepileptic therapy on sleep disorders in women with epilepsy].

Abstract

Objective: To analyze the frequency of various sleep disorders in patients with epilepsy receiving antiepileptic therapy.

Material and methods: Sixty-four women were selected from the register of patients with epilepsy and other paroxysmal conditions. The group consisted of young and middle-aged women (36.9±13.5 years), all patients received antiepileptic therapy. To diagnose sleep disorders, we used a sequential algorithm for clinical examination supplemented by instrumental methods according to indications (polysomnography, respiratory monitoring).

Results: The duration of epilepsy was 15.7±7.6 years, the disease was represented by three forms: structural (n=15, 23.4%), genetic (n=32, 50%) and unspecified (n=17, 26.6%). Sleep disorders were common among female patients with epilepsy (43.7%), they are most frequently combined with genetic epilepsy (18.7%), and represented by: insomnia (43%) mild to moderately severe breathing disorders (32%) and sleep movement disorders (25%). Sleep disorders were combined with symptoms of depression in the majority of patients (71%). A 6-month follow-up evaluation of nighttime sleep parameters after treatment showed a decrease in the frequency of sleep disorders to 25%; scores on the Epworth Sleepiness Scale significantly decreased to 6.7±3.6. A change in antiepileptic therapy in patients with sleep breathing disorders resulted in a marked regression of the Apnea-Hypopnea Index (9.2±2.5 points; p=0.003). However, there were no significant changes in the severity of sleep movement disorders.

Conclusion: Sleep disorders are common in patients with epilepsy, in most cases they are associated with mood disorders, and may regress after optimization of antiepileptic therapy.
