Abstract

Publisher Summary Reflex epilepsies are those in which the stimulation of sensory receptors induce seizures or convulsions in a consistent manner. In humans, the reflex epilepsies can be divided into two groups. The first group consists of those induced by simple sensory stimulation–somatosensory auditory and visual. The second group is those induced by complex stimuli, such as reading epilepsy, musical epilepsy, eating epilepsy, and thinking epilepsy. Somatosensory reflex epilepsies are usually seen in young patients. Many of these patients demonstrate high amplitude somatosensory-evoked potentials (SEP) similar to those seen in a variety of neurological conditions, including progressive myoclonus epilepsy, Ramsey–Hunt syndrome, and myoclonic encephalopathies. These high amplitude SEPs usually consist of enlarged N60 components elicited by tactile stimuli, such as tapping and may be accompanied by clear discharges seen in the electroencephalograph (EEG). The most common reflex epilepsy seen in humans is photosensitive epilepsy. Approximately, 1 in 4,000 of the population is thought to have photosensitive epilepsy.
