What is a Coma?
A coma is a state of deep unconsciousness in which a person cannot be aroused, even by strong stimuli such as pain. It can last for days, weeks, or even longer. During a coma, a person will not respond to his or her environment, and cannot be awakened.
Signs and Symptoms of a Coma
The signs and symptoms of a coma vary depending on the underlying cause. Generally, people in a coma will have:
• Unresponsiveness to stimuli
• Abnormal breathing patterns
• Eye closure or lack of blinking
• Flaccidity (floppy muscles)
• Abnormal eye movements
• Absence of facial expressions
• Loss of reflexes
• Lack of speech
• Absence of voluntary movement
Diagnosis of a Coma
If you suspect that someone you know is in a coma, it is important to seek medical attention immediately. A doctor will perform a physical examination, as well as imaging tests such as a CT or MRI scan, to determine the cause and extent of the coma.
Treatment of a Coma
The treatment of a coma depends on the underlying cause and the extent of the damage to the brain. Treatment may include medications, supportive care, and physical therapy. In some cases, surgery may be required to treat the underlying condition.
