Hyperreligiosity in temporal lobe epilepsy: redefining the relationship.

Seventy-six subjects with the primary diagnosis of complex partial seizures with a unilateral temporal lobe focus were examined for the presence of hyperreligiosity. Fifty-one subjects had a left temporal lobe seizure focus and 25 had a right temporal lobe seizure focus. In addition to the temporal lobe epilepsy (TLE) groups, two reference groups were also examined. The first consisted of 31 subjects with primary generalized seizures. The second control group consisted of 27 subjects with documented pseudoseizures and no objective evidence of recurrent epileptic seizures. In all cases, the documentation of seizures or pseudoseizures as well as the localization of the seizure focus was accomplished through simultaneous videotaped recording of the 16-channel scalp EEG tracing and the concurrent overt behavior during the ictal phase. The results of this study fail to support the hypothesis that individuals with TLE are characteristically hyperreligious during the interictal state. There were no significant group differences between the left vs. the right TLE groups, nor were there any significant group differences between the two TLE groups vs. the two comparison groups.
