It generally happens very suddenly and it can take up to five to seven days to completely effect the patient. Depending on how many of the brain cells die during the stroke, and where the cells are located in the brain will determine the severity of the outcome. During the stroke, the supply of the blood to the brain has been severed and after four minutes, the brain cells begin to die.

Three out of ten victims of stroke within the first month will die and some will die at onset of the stroke and the remaining will recover to some extent. Some patients will recover completely from their strokes and some of these strokes can completely wear off. These are called transient ischaemic attacks and are a warning that a full-blown stroke can happen, unless some action is taken to prevent strokes from reoccurring.

The reason for this is that the brain itself is incapable of feeling pain. One in three patients having a stroke will lose consciousness while they are having a stroke and a majority of the time these are the most severe cases.
