A new study has offered evidence that cases of insomnia in people with epilepsy may not be directly caused by their condition.
Conducted by South Korea’s Soonchunhyang University College of Medicine, in association with three US centres, the research suggested that depression and other comorbid conditions have more to do with causing insomnia than epilepsy itself.
Of the 90 adults with epilepsy involved in the study, it was shown that 65.5% reported insomnia, with 28.9% experiencing moderate or severe sleep problems.
According to results published in the medical journal Epilepsy & Behavior, insomnia was associated with shorter sleep duration, the use of sedative-hypnotic drugs, head trauma and the presence of asthma or chronic obstructive pulmonary disease.
It was also shown that receiving multiple antiepileptic drugs increased the likelihood for moderate to severe insomnia.
The researchers conclude: “Our findings indicate that severity of insomnia in adults with epilepsy is more likely to be associated with comorbid medical and depressive symptoms and less likely to be directly related to epilepsy.”
