### input:
Hi i am 22 female here, my elderly grandmother has had her third and most severe stoke and has been unconscious since. For about a week now she has been unconscious, she seems to have some psychical movement and mutters some words but the doctors and nurses say it is not a good sign that she has still not woken up. They say eventually she may starve and weaken because she is only supplied food through the liquid food attached to her and it is unhealthy to stay bed ridden for too long. Can somebody please give me a better idea on what may be wrong and how exactly a stroke works and what are the chances of her waking up considering she has some psychical movement and at times opens her eyes and just stares into the distance. Is it possible for the brain to reconstruct its self somehow?

### output:

Hi!!  . Strokes are of 2 types - Ischemic stroke where there is obstruction to the blood flow secondary to either narrowing of blood vessels or dislodged clot obstructing the blood follow. The other form of stroke is bleeding. Symptoms of stroke depends on the area and extent of brain affected by stroke... In this sense, stroke causing unconsciousness indicates a larger/important area of the brain has been affected. Though stroke affected brain doesn't recover, clinical symptoms will improve gradually. On the contrary, other areas of the brain can also get affected due to edema and pressure effects or fresh stroke development. This can lead to worsening of the condition. Such events are common during the initial few days following a stroke. They are not so common after a week. Apart from the risks of other areas of brain getting affected, an unconscious/bedridden individuals have a higher risk of developing bed sores and infections which add to the morbidity. The progress of the illness is monitored closely through a set of parameters - Glass glow coma scale, heart rate, blood pressure and respiratory activity... The extent of recovery depends on the right choice of treatment and later the physiotherapy.  Its isn't an easy task to predict the chances of recovery from this far. The doctors treating her too may face the same difficulty predicting the chances of recovery. A positive approach, right treatment and active physiotherapy are the factors enhancing recovery. My prayers and wishes to your grandmother... Regards
