Neurological disturbances may be present at high altitude independently of high altitude cerebral edema. We report here the case of a patient who experienced for the first time generalized seizures after spending a night at an altitude of 5200 m, with no preceding symptoms of acute mountain
Neurologic problems at high altitudes are well known. What is probably less emphasized are neurologic problems at altitude outside the setting of high-altitude cerebral edema. Because neurologic symptoms for these kinds of problems at high altitude are often transient, neuroradiologic scanning for
Altitude sickness in its commonly recognized forms consists of acute mountain sickness and the two life-threatening forms, high altitude cerebral and pulmonary edema. Less well known are other conditions, chiefly neurological, that may arise completely outside the usual definition of altitude
A 35-year-old healthy Dutch woman went on a trek (Lang Tang) in Nepal up to an approximate altitude of about 3800 meters. She had no prior history of any medical problems except attacks of generalized epilepsy when she was 19 years old, which had been controlled with antiepileptic medications. She
A healthy 20-year-old man failed to return home after a jog in the Colorado mountains. His lifeless body was found the next day on an exposed mountain slope. The differential diagnosis in such mysterious, unwitnessed mountain deaths includes cardiac arrhythmia, cerebral hemorrhage, pulmonary
Acetazolamide (AZ) is an carbonic anhydrase inhibitor, which has been used in the treatment of seizures, mountain sickness and glaucoma. Memory impairment by AZ has been reported in patient interviews; however, the related mechanism is unclear. We applied two fear conditioning paradigms, shuttle
Travel is associated with a number of neurological disorders that can be divided into two categories: (1) Neurological infections including encephalitides, neurotuberculosis, neurobrucellosis, cysticercosis and trichinosis. Some of these disorders can be prevented by vaccinations, such as Japanese B
Acclimatization is a major pathophysiological concern during ascent to high altitude and may cause mortality in unacclimatized individuals. Absence of target drugs, especially prophylactics, emphasizes the need for development of herbal agents. Present study revealed that animals pre-administered
BACKGROUND
Hypertensive encephalopathy (HTE) is a syndrome typified by headache, seizures, and neurologic signs associated with increased systemic blood pressures; edema in the subcortical white matter is seen on imaging studies and is usually reversible, although infarction or hemorrhage may
As increasing numbers of people live, work, and play at high altitudes, awareness of the neurological consequences of hypobaric hypoxic environments becomes paramount. Despite volumes of studies examining the pathophysiology of altitude sickness, the underlying mechanisms of the spectrum of altitude
