Hi!! Welcome to healthcaremagic forum..
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/bed ridden 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 - Glassglow coma
scale, heart rate
, blood pressure and respiratory activity... The extent of recovery depends on the right choice of treatment and later the physiotherapy
It's 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...
