Photoepileptic

The effect of stroboscopic photostimulation upon an institutionalized, mentally retarded, photoepileptic male was studied.

The oscillating visual stimulus required to elicit an SSVEP can be (depending on the stimulation frequency) annoying for the user and even dangerous since it can trigger photoepileptic seizures.

This report focuses on generalized photoepileptic responses (PERs) not previously reported in patients with subdural electrodes.
