Hyperreligiosity is a neurobehavioral symptom, manifest as sudden religious conversion, or increased and unswerving orthodoxy in devotion to religious rituals. It may be encountered along with hypergraphia and hyposexuality as a feature of Geschwind’s syndrome. It has also been observed in some patients with frontotemporal dementia; the finding is cross-cultural, having been described in Christians, Moslems, and Sikhs. In the context of refractory epilepsy, it has been associated with reduced volume of the right hippocampus, but not right amygdala.
