Detailed Answer:
Hi
Firstly thanks for choosing health care magic for your query!

Have noted all your details,

Strokes are of two types- ischemic and hemorrhagic. Ischemic stroke is the most common type. It is usually caused by a blood clot that blocks or plugs a blood vessel in the brain. This keeps blood from flowing to the brain. Within minutes, brain cells begin to die. Another cause is stenosis, or narrowing of the artery. This can happen because of atherosclerosis, a disease in which plaque builds up inside your arteries.In miss Shamim case MR angio shows both infarct as well as stenosis,Hence severity of symptoms are more.

Stroke affects everybody differently. Many stroke survivors continue to improve over a long time, sometimes over a number of years. Recovery from stroke involves making changes in the physical, social and, emotional aspects of your life.It's very difficult to predict to what degree someone will recover and how long will it take.

Trials showed that recovery depends upon the type of stroke you had, how much brain damage occurred from the stroke, your age, and how quickly rehabilitation begins.

In your case its a large infarct in fronto parieto occipital region, 3 out of four regions are involved, so recovery will definitely take a very long time.

Formal rehabilitation takes place for about three to six months. But studies have shown that stroke patients who continue to practice the skills they learned in rehabilitation continue to see progress long after a stroke has occurred.

Advice
Keep the patient motivated.
Medications should be followed as suggested by neurologist.
Physical rehabilitation therapy should be started under guidance of a physiotherapist as soon as possible.
To be XXXXXXX full recovery may take upto a year in your case, even after aggressive medical and physical therapy.
