OCD means what: Please do not use acronyms when addressing questions. Explain what you mean. By using acronyms you introduce a significant chance for confusion. I've been practicing medicine for 45 years and have no idea what you are talking about. If you mean obsessive compulsive disorder, what relevance does this have in coma? None. Or do you mean oculocerebral dystrophy? Or.....?
Dr. Pamela Pappas
Psychiatry 42 years experience
OCD & Coma?: If one were comatose, s/he would not be awake to be obsessing or doing compulsive behaviors. Unless i'm completely missing the meaning of your question, i'd say that OCD is completely unrelated to coma.

Coma: Being unresponsive, i can think of no correlation as a cause & effect.

A 38-year-old member asked:

What is the longest known coma a person has actually woken up from?

Dr. Joseph Sucher
Trauma Surgery 26 years experience
Many years: There are anecdotal stories all over the world of patients awakening from comas after 10 and even 20 years. The reality is that as time goes on, the likelihood of awakening from a coma decreases, and if a patient does regain consciousness after some prolonged period, the likelihood of normal function would be quite dismal.

How long is too long for a person to be in a coma and fully recover?

Dr. Terry Simpson
General Surgery 35 years experience
Coma time: No great work has been done. The amount of time is less important than the brain that is left to recover.

How long does it take for a coma patient to start remembering things?

No fixed answer: This question can only be answered on an individual basis. There are too many variables to answer here. The range is from one second (concussion) to never (permanent coma).
A 38-year-old member asked:

What are the chances of surviving a coma?

1 doctor answer2 doctors weighed in
Dr. Sue Ferranti
Internal Medicine 29 years experience
Depends...: In general, surviving coma depends on the reason for the coma and whether the etiology of the coma is reversible or not. The longer the person is comatose, the less likely they will awaken. These are generalities, however, so ask your doctor about the specific case to find out the chance of survival of the individual patient as each case is different.
A member asked:

When a person wakes up from a coma are they tired?

1 doctor answer2 doctors weighed in
Dr. Peter Glusker
Neurology 47 years experience
Coma: "tired" and "alert" refer to normal daily circadian rhythms relating to sleep and waking states. A coma is a different state, with brain dysfunction caused by many things (infection, low oxygen, toxins, continued seizures, medications and others. When the coma is resolved, the brain will return, slowly, to the normal waking and sleeping rhythms. The transition out of coma is more or less slow.
