Transient high altitude expressive aphasia.

Abstract:

:Transient focal neurological deficits have been described in sojourners to high altitude. We present two cases of transient expressive aphasia in well-acclimatized high altitude climbers. We speculate that this type of transient focal neurological impairment may represent migraine aura, and we discuss other reports of transient focal neurological deficit at high altitude.
