I read your question carefully and I understand your concern.
That
MRI speaks of
ischemic stroke, damage to a brain area due to blood flow being stopped as a blood vessel is occluded and no body part can survive for more than some hours without blood.
Now stroke is a medical emergency, so any acute stroke should be admitted to a hospital. I am afraid that after the first hours there is no treatment to reverse the damage, the area is already damaged.
However being admitted in a hospital, in a stroke
unit or neurology department is essential for several reasons. First in order to prevent complications like infections, aspiration etc. Second to start
physical therapy in order to regain function. Third to have tests to find the cause of the stroke in order to take preventive treatment so that other strokes in the future are avoided. Preventive treatment is with a blood thinner, but the type of the blood thinner depends on the origin, whether from a heart arhythmia, vessel
atherosclerosis, or other more rare causes.
I hope to have been of help.
