The CT scan
report is not available as you have mentioned.But as you have pointed out here the deficits or weakness are not severe like the previous stroke
in 2009. He is likely to recover with physiotherapy
and medications like antiplatelets, statins and other supportive medications.
It is important to have strict control of Blood sugar as the two factors which can adversely affect recovery in a stroke patient is High blood sugar and raised temperature. Tight control of blood sugar should be possible with Insulin
while he is in the hospital.Also encourage him to do physiotherapy and stay motivated and in a relatively optimistic frame of mind which helps in a positive recovery.
Hope this helps.
