[Headache and generalized epileptic EEG activity due to strong light exposure].

The case of a 16 years old girl with bilateral headache attacks and simultaneous generalised paroxysmal activity in EEG triggered by light is reported. Headache intensity as well as the number of generalised spike wave discharges under photic stimulation depended on intensity of light whereas wavelength of used light had no influence. Paroxysmal activity was most intensive at a flash light frequency of 25 Hz.
