Can people in comas hear?

Comatose patients do not seem to hear or respond. Speaking may not affect their clinical outcome; time spent with them takes time away from other, more "viable" patients. Comatose patients may, however, hear; many have normal brain-stem auditory evoked responses and normal physiologic responses to auditory stimuli.

Can a coma last 1 day?

Depending on the cause and the extent of damage, a coma can occur rapidly or gradually, and it can last from several days to months, though most last from days to weeks.

What do people see in a coma?

Why do bodies go into comas?

More than 50% of comas are related to head trauma or disturbances in the brain's circulatory system. Problems that can lead to coma include: Anoxic brain injury. This is a brain condition caused by total lack of oxygen to the brain.

Is a coma like sleep?

What types of comas are there?

Where is your mind during a coma?

When someone is in a coma, they cannot interact with their environment. The brain is still working, however, and the degree of brain activity varies from patient to patient. New tools for mapping brain activity have helped doctors illuminate what is happening inside the brain, which informs their treatment and care.

What type of death is a coma?

Coma is a state of prolonged loss of consciousness. It can have a variety of causes, including traumatic head injury, stroke, brain tumor, or drug or alcohol intoxication. A coma may even be caused by an underlying illness, such as diabetes or an infection. Coma is a medical emergency.
