Which of the following is NOT associated with signs of HACE?

High Altitude Cerebral Edema (HACE) is a serious condition that can occur at high altitudes due to the accumulation of fluid in the brain. The classic signs and symptoms of HACE include ataxia, headache, and confusion.

Ataxia refers to a lack of muscle control or coordination, which is often seen as a significant impairment in balance or movement in individuals experiencing HACE. A headache is a common symptom associated with altitude sickness in general and is often one of the earliest signs of HACE. Confusion can manifest as altered mental state or cognitive impairment, which is due to increased pressure in the brain caused by edema.

Excessive sweating is not typically associated with HACE. Instead, signs of HACE usually involve neurological symptoms and behavioral changes rather than physiological responses like sweating. Thus, the correct choice identifies a symptom that does not align with the recognized indicators of this serious altitude-related condition.
