Evaluation of sleep quality in spouses of people with epilepsy

The objective of this study was to evaluate the spouses of people with epilepsy with and without a history of seizures during sleep in terms of depression, anxiety, and sleep quality.

This prospective, cross-sectional study was conducted in three groups of 18-55 year olds, who were at least primary school graduates. The 1st group consisted of healthy spouses of 30 healthy volunteers with age and sex matched with the other groups. The 2nd group comprised spouses of 30 people with epilepsy who had been married for at least one year and had no history of seizures during sleep. The 3rd group consisted of spouses of 30 people with epilepsy who had been married for at least one year and had a history of at least one seizure during sleep in the course of the previous year. The questionnaire including demographic data, Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) was applied to all participants.

The mean age of the 1st group was 35.07 ± 8.33 years, that of the 2nd group was 36.47 ± 7.63 years, and that of the 3rd group was 35.33 ± 6.05 years. There was no significant age difference between the groups (p = 0.740). The depression scores of the 2nd and the 3rd groups were significantly higher than that of the 1st group (p < 0.001, for both). The anxiety scores of the 3rd group were significantly higher than those of the 1st and the 2nd groups (p < 0.001 and p = 0.001, respectively). Thirty percent (n = 9) of the 1st group, 40% (n = 12) of the 2nd group, and 70% (n = 21) of the 3rd group had poor sleep quality. The sleep disorder rate in the 3rd group was significantly higher than in the 1st and the 2nd groups (p = 0.002 and p = 0.020, respectively). When the PSQI subscales were examined, the sleep quality, sleep latency, usual sleep efficiency, daytime dysfunction, and the total sleep total score were significantly higher in the 3rd group than the 1st and the 2nd groups. The patients in the third group had significantly higher scores of sleep duration, sleep disturbance, and sleep medication use than those in the 1st group.

We found out that the PSQI score, which reflected the sleep quality, was poor in the spouses of people with epilepsy, who had seizures during sleep. To the best of our knowledge, these findings are the first in the literature on this subject.
