Yes!!: Abnormal posturing can occur in a large variety of conditions from psychiatric states (e.g. Catatonic schizophrenia) to organic conditions including drug reaction, cerebral palsy, extrapyramidal disorders (such as chorea, parkinson's disease, hemi ballismus dystonia's etc) the list is not exhaustive! ...Read more

Yes: A coma is a very serious condition associated with head injury and a certain percentage of people do not survive, however many people do survive and even recover to a great degree.

Can a patient be in coma for less than 6hrs (as 6hrs is minimum)? What's the diagnose that someone is in coma?
A coma is a: Prolonged state of unconsciousness, during which a person is unresponsive to his or her environment, is alive and appears to be sleeping, but, unlike being in a deep sleep, the person cannot be awakened by any stimulation, including pain. I do not think there is a minimum time frame but, according to www. Brainandspinalcord. Org, a coma can last for a few seconds, or can last for years. ...Read more
Physical exam: I agree with dr. Singer. There are certain aspects of the neurological exam that can also be done which can help determine if the brainstem is functioning. But the confirmatory tests are outlined by dr. Singer. ...Read more
Yes: A coma occurs when the brain is injured. Recovery depends on whether the injury can be reversed. I have seen people in comas from a brain infection completely recover when the infection was treated. On the other hand, a person in a coma from a head injury may recover partially, or not at all. The longer the coma, the lower the chance for recovery. Ask a doctor the reason for the coma. ...Read more
Does decorticate & decerebrate posturing during hypoglycemia followed by coma mean that a person has brain damage?
Posturing: It is definitely concerning to have this posturing. The ability to recover would relate to the amount of time the patient was hypoglycemic. ...Read more
Depends on reason: Person is in coma. Often, when a patient is in a coma, they need breathing support as well. If they do, then removing that, they may succumb in just a few minutes. They could pass from what ever other ailments they have fairly quickly from those issues as well. If they are stable in a vegetative state and do not breathing support, they can live until they pass from dehydration or malnutrition. ...Read more

It is difficult to predict the life expectancy. Existing data shows mostly it is. ...Read more
My sister was in an induced coma for two weeks in november. Now when she does light activity she gets shaky. Is this normal? Is is it temprorary?
Coma: Think of the brain as having a wake and sleep center. When something bad happens to the wake center of the brain, it can no longer do its job to keep the brain awake in the spectrum of maintaining cousiousess. This can be from an anatomic/structural and/or physiological problem. Some of these are reversible and some are unfortunately not. ...Read more
Brain injury: Deep centers of the brain control the ability to react to our environment and control our basic needs. When these deep centers are damaged we lose the ability to react and control. This is described as a state of coma. Brain swelling, brain infection, brain hemorrhage, stroke, trauma, all can result in a state of coma. Recovery depends on the degree of initial damage. ...Read more
Redirection of blood: Even though there is a dramatic increase in blood flow to the stomach and intestines after a meal (proven by ultrasounds) it is thought that it is the increased parasympathetic nervous system activity (opposite of the fight or flight sympathetic activity) which causes the feeling of lethargy. ...Read more
Multifactorial: Coma means unarousable unresponsiveness. It is caused by injury to both cerebral hemispheres or the central brain stem or both. The cause is either traumatic or non traumatic. Non traumatic causes are many - anoxic/ischemic, metabolic, endocrine, infectious, degenerative, etc. It is a clinical term with many disease types as cause. ...Read more
Difficult question: It depends if the underlying reason that caused the coma is reversible or correctable. Even then it is difficult as it depends if there was too much insult to the brain or not. Recovery from coma is such a variable thing that it is difficult to answer without knowing about the specific situation. I wish I could be of more help on this, its just such a complicated thing. ...Read more
Resolution: Coma affects the base of the brain, brainstem, the same area responsible for concussion outcomes. As a disorder heals, and inflammation or swelling decreases, gradually the reticular activating system switches back on, and responses resume. However, on occasion this can be a lengthy restoration, maybe even months and very rarely yrs. ...Read more
Please clarify: Are you asking, "When people in comas die, what do they die of? " Or do you mean, "I don't understand why people in comas die instead of everyone getting better, waking up, shaking their doctor's hand, waving to the nurses, and going home."? Please repost your question so that it can be understood. ...Read more
Unsure: Hard to say. I frequently take care of patients in medically-induced (medication) comas and comas from trauma/strokes. I have never had a patient wake up and give me an assessment. Those that do wake up, do not recall the events. ...Read more
Coma: People emerge from coma in varied fashions and to different extents. For example, people who are in medically-induced comas may emerge from this as medication is allowed to wear off. Alternatively, a person in a coma from a disease state may emerge from coma as the disease state improves. This can be rapid (hours to days) or slow (weeks or months). Some people fully recover. Others may not. ...Read more
