A 36-year-old man with a history of migraine headache attempted to hike from Lukla, Nepal, to Mount Everest Base Camp. On the sixth day of hiking, he had a migraine headache. After achieving resolution with typical therapies and rest, he ascended higher. Another headache developed that was
BACKGROUND
Headache is the most common complication associated with exposure to high altitude, and can appear as an isolated high-altitude headache (HAH) or in conjunction with acute mountain sickness (AMS). The purpose of this article is to review several aspects related to diagnosis and treatment
High altitude headache (HAH) and acute mountain sickness (AMS) are common pathologies at high altitudes. There are similarities between AMS and migraine headaches, with nausea being a common symptom. Several studies have shown ibuprofen can be effective for AMS prophylaxis, but few This article gives the probable location within 65 km of the Big Headache Mountain where mountain sickness was first reported by Too Kin, a Chinese official, in 37-32 B.C. We believe that traveling over the western edge of the Himalayan Karakoram Range or in the Pamirs caused the major difficulties,
Few studies have evaluated high altitude headache (HAH) and acute mountain sickness (AMS) in military populations training at moderate (1,500-2,500 m) to high altitudes (>2,500 m). In the current study, researchers interviewed active duty personnel training at Marine Corps Mountain Warfare Training
BACKGROUND
Acute Mountain Sickness (AMS) refers to signs and symptoms associated with hypobaric hypoxia. Its reported incidence is highly variable.
OBJECTIVE
To determine the incidence of AMS symptoms and severity at 3,500 and 4,250 m above sea level.
METHODS
A population of 362 soldiers without
Acute mountain sickness is a pathologic reaction as a result of bad adaptation to high altitudes (greater than 2.500 meters). The main symptoms are headache, nausea, vomits, and insomnia. When severe it can produce oliguria, retinal hemorrhage, ataxia and sometimes coma. Its etiology is not well
Cluster headache is described here as having three distinct and contiguous clinical phases. Evidence of the pathophysiological changes associated with each phase is reviewed. The first phase, the cluster period, is characterized by chronobiological aberrations and impaired sympathetic nervous system
No evidence is available to show that nasal congestion is a manifestation of exposing an individual to high altitude and hypoxia. Since both nasal congestion and high-altitude headache are vasogenic, we explored whether there is a coincidence between these two symptoms. A prospective observational
Due to the decreasing partial pressure of oxygen, high altitude sickness can occur at heights over 2,500 m. This can be best avoided by slow adaptation to the altitude (acclimatization). In this way the organism adapts to the chronic hyperventilation and in the further process the oxygen content is
