Treatment of stroke
and chances of recovery depends on the size of stroke and the duration of complaints.
Presuming you meant the small ischemic foci is on the right cerebral hemisphere
, the affected brain is not huge and prognosis is good. If his complaints are recent one and my presumption is right, then he should be able to recover easily.
The medications given to him are appropriate and he needs to continue with it religiously. In addition the most important aspect is to start and continue effective physiotherapy
with the help of an experienced physiotherapist. This is the most crucial element to make your father recover from the paralysis
and get back to his normal activity.
So if you haven't started the physio yet, discuss with your neurologist
and start it at the earliest. He should improve very soon with it.
Hope this helps.
