What is a "coma"?
A coma is a state of deep unconsciousness where a person cannot be woken up, open their eyes, or respond to their environment. It can be caused by various factors, such as severe head injury, stroke, drug overdose, or metabolic disorders. While in a coma, the brain's activity is significantly reduced, and the person is unable to perform voluntary actions. Comas can range in duration from a few days to several weeks or even longer. Treatment involves addressing the underlying cause and providing supportive care to protect the person's health and promote recovery if possible.
