Religious Experience and Clinical-EEG Aspects in Adult People with Epilepsy.

Abstract

Spirituality and religiosity are complex cognitive phenomena; however, the relationship between spiritual experiences and epilepsy continues to be debated. Methods. Data from the daily spiritual experience scale (DSES) were related to EEG data and clinical variables of 100 adult people with epilepsy (PWEs). DSES scores were compared to 51 normal individuals (control group [CG]), with a significance level of P < .05. Results. The total score in the DSES was 36.1 ± 14 and 37.6 ± 13.2, respectively, in the PWEs and in the CG. In the PWEs, there was a correlation between DSES and age (Pearson's correlation; -0.22; P = .027) and educational level (0.207; P = .039). PWEs with ≥one seizure/month have a lower frequency of daily spiritual experiences than those with better controlled seizures (T-test; 39.2 ± 16.2 vs 31.7 ± 7.6; P = .038). EEG epileptiform activity (EA) in the right hemisphere was associated with a higher frequency of spiritual experiences than those with left-hemisphere EA (29.8 ± 9.0 vs 38.5 ± 17.5; P = .010). Conclusion. Demographic aspects, EA in the right hemisphere, and lower seizure frequency are associated with daily spiritual experiences in epilepsy, suggesting an association between aspects of spirituality, epilepsy, and neurobiological correlates.
