This case report describes three separate episodes of isolated ataxia, hallucinations of being accompanied by another person, and bilateral dressing apraxia occurring in a single individual without prior warning signs. These symptoms are attributable to disruption of vestibular processing in the temporoparietal cortex or associated limbic structures. Neurological dysfunction at high altitude is...

introduction: chronic mountain sickness (cms) represents a syndrome of secondary polycythemia along with thrombocytopenia, altered hemorheology, pulmonary and systemic hypertension, and congestive heart failure, occurring due to hypobaric hypoxia-anoxia-induced erythropoiesis reported in both native mountain residents and new climbers after prolonged stays at high and extreme altitudes.case pre...

The hypoxic conditions of extreme altitudes have long been known to have psychological and physiological effects on humans. Such conditions may also impact an individual’s economic valuation and decision-making process relative to non-hypoxic conditions. Building on prior work both in the psychology of economics and the effects of hypoxia on psychology and decision making, this study gathered c...

The increased prevalence of high altitude sickness such as Acute Mountain Sickness (AMS), High Altitude Cerebral Edema (HACE), and High Altitude Pulmonary Edema (HAPE) are related to the increasing popularity of mountain climbing as an adventure sport; and the increasing ease, and decreasing cost of travel to popular climbing tourist destinations. This precludes the usual preparations and adapt...

Chronic mountain sickness (CMS) represents a variably reversible asynchronous syndrome of secondary polycythemia along with erythrocytosis, erythrocyte aggregation, hemoglobinemia, hemoconcentration, thrombocytopenia, increased whole blood viscosity, fibrinogenemia, prothrombotic state, pulmonary and systemic hypertension, and congestive heart failure, occurring due to hypobaric hypoxia-anoxia-...

Competition at elite level can require athletes to perform optimally in extreme environmental conditions. This review focuses on mood responses in such conditions and proposes practical guidelines for those working with athletes. Different environments are considered, including altitude and extreme heat and cold. Performing in extreme heat, cold or at altitude can produce a stress response char...
