PHILADELPHIA – . Insomnia symptoms are not associated with epilepsy type, number of antiepileptic drugs (AEDs), or AED standardized dose, however.
“Given the potential benefits of sleep therapies on epilepsy outcomes, routine screening of insomnia symptoms is warranted,” said lead study author Thapanee Somboon, MD, a researcher at the sleep disorders center at Cleveland Clinic Neurological Institute in Ohio and at Prasat Neurological Institute in Bangkok.
Insomnia is common and associated with depression in patients with epilepsy, but prior studies that looked at the relationship between insomnia and epilepsy-related characteristics yielded limited and conflicting results, according to Dr. Somboon.
To evaluate potential associations between insomnia and epilepsy, Dr. Somboon and colleagues conducted a prospective analysis of data from 270 patients with epilepsy who presented to the Cleveland Clinic Epilepsy Center for an initial evaluation between January and August 2018. The patients completed the Insomnia Severity Index (ISI). An ISI score of 8 or greater indicated clinical insomnia symptoms, and an ISI score of 15 or greater indicated moderate or severe insomnia symptoms.
The researchers used Spearman’s correlation and the Kruskal-Wallis test to evaluate associations among insomnia symptoms and AED standardized dose, monthly seizure frequency, Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Questionnaire (GAD-7), and Quality of Life in Epilepsy-10 (QOLIE10).
Among the 270 patients, the average age was 43.5 years, 58% were female, 74% had focal epilepsy, and 26% had one or more seizures per month. The population’s median ISI score was 7. Nearly half had an ISI score of 8 or greater, and 23% had an ISI score of 15 or greater.
“A positive correlation was found between ISI and PHQ-9 (r = 0.64, P less than .001), GAD-7 (r = 0.68, P less than .001), QOLIE (r = 0.55, P less than .001), and monthly seizure frequency (r = 0.31, P less than .001),” the researchers reported. Insomnia symptoms had a significantly stronger correlation with PHQ-9 and GAD-7 than with seizure frequency.
