A coma is a deep state of unconsciousness, your brain is at its lowest activity level.
No. Exams of patients with encephalitis (inflammation of the brain) usually reveal a drowsy or confused patient but not in a coma. A person in a coma state can not be aroused.
There are several different ways a person can end up in a coma due to a brain injury. A person can go into a coma if the brains swells or bleeds after the injury.
You will be brain dead!! coma
The brain is constantly working even if a person is in a coma. The only reason this would change is because the person has gone brain dead and the brain is no longer producing waves of activity.
Since a coma is just going to sleep and never waking up, a coma shouldn't cause brain damage. It is just that the brain is in a permanent mode of sleep in which the victim cannot be aroused.
In most cases, yes.
COMA
Because at very high levels alcohol can sufficiently slow the brain so as to cause a coma.
Any brain damage obtained before the state of coma is what causes clawing hands during a coma. This is what is commonly called a vegetative state.
metabolic causes of coma consist of those conditions that change the chemical environment of the brain, thereby adversely affecting function.
Vasculitis of blood vessels in the brain can lead to headaches, confusion, personality changes, seizures , and coma
