coma

A coma is a state in which a person is unconscious and unable to respond to their surroundings. It occurs when the brain's normal functioning is disrupted, often due to injury, illness, or other factors affecting brain activity. During a coma, the person cannot speak or move intentionally, but some brain functions, like breathing and heartbeat, may continue. The depth and duration of a coma can vary, and recovery depends on the cause and severity. It is a serious medical condition requiring close monitoring and treatment to support brain health and address underlying issues.
