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 symptoms of HACE typically include severe headache, ataxia (which refers to loss of coordination), and sleep disturbances.

Numbness in extremities is not a primary symptom associated with HACE. While some neurological symptoms can occur at high altitudes, numbness is more commonly linked to peripheral nerve issues or altitude sickness like High-Altitude Pulmonary Edema (HAPE) rather than HACE specifically. Understanding these distinctions is crucial for effective assessment and management of high altitude illnesses.
