INTRODUCTION:
In most instances, the physiopathology of exercise-triggered headache remains ill defined. We present the modifications of visual cortex activity evaluated using EEG in a patient suffering from headache induced by exercise, before and after exertion.
CASE PRESENTATION:
We present a 36 years old otherwise healthy male under evaluation for headache crises with migrainous features (with intense photophobia) provoked by physical activity. Attacks respond to ergotamine-containing compounds, but cannot be prevented using common anti-migraine prophylactics. Laboratory tests, magnetic resonance angiography and cardiac and neck blood vessels Doppler ultrasound were normal. An electroencephalographic recording was performed at rest and during 3 consecutive blocks of visual stimulation (checkboard pattern-reversal) before and after a graduated ergometric evaluation. Independent components of EEG activity were extracted to assess visual cortex activity in the frequency domain.
The electrophysiological patterns observed were similar to those previously described on migraineurs in-between and during headaches.
CONCLUSIONS:
If replicated in an adequately sized sample, our findings may suggest that exercise-induced headache in subjects without any vascular, structural, or cerebrospinal fluid dynamic alterations and migraine may share a common physiopathological background.
