In more severe cases a coma may last for over five weeks, while some have lasted as long as several years. After this time, some patients gradually come out of the coma, some progress to a vegetative state, and others die. Some patients who have entered a vegetative state go on to regain a degree of awareness. Others remain in a vegetative state for years or even decades (the longest recorded period being 42 years). The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage.

A coma occurs when a part of the brain is damaged, either temporarily or permanently. This damage results in unconsciousness, an inability to awake, and unresponsiveness to stimuli such as pain, sound, and light. Comas have a number of potential causes. These range from injury or illness to stroke, to tumors, to alcohol and drug abuse. A person who is in a coma is alive but is unable to move at will. They canât think, speak, or respond to their environment.
