High Alt Med Biol. 25:100-102, 2024.-High altitude cerebral edema (HACE) is a severe form of acute mountain sickness (AMS). Besides this life-threatening condition, other neurological disorders may develop at high altitude, even if the precise pathophysiological mechanisms generally remain undetermined and are often debated. We report the case of a 34-year-old woman presenting with moderate AMS during an ascent of Mount Kilimanjaro. While descending from the summit, she suddenly experienced focal neurological symptoms of visual blurring, tinnitus, lightheadedness, and the findings of left-sided central facial palsy (flattened nasolabial fold, fall of labial commissure, dysarthria, difficulty in whistling, and facial dysesthesia). These symptoms and signs were confirmed in the field by a physician. Her symptoms regressed spontaneously and completely while continuing to descend. The etiology of this neurological episode at high altitude is discussed. The most probable diagnosis is a transient ischemic attack based on personal and familial vascular history, confirmed unilateral transient central facial palsy and normal results on standard blood work and cerebral magnetic resonance imaging. In this case, migraine should also be considered based on association of headache and transient focal neurological…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
