Hi Sekar, Welcome to HealthcareMagic Forum.
Your Aunty is having Dysarthria
which is a motor speech disorder
which occurs after brain injury
following stroke. You haven't mentioned if she is Diabetic or Hypertensive? Going by her health history i feel she has suffered a Brain Attack (Stroke) which a CT scan has confirmed according to your Neurologist
. She may be on right medications, Kindly let me know which are they?
Good Luck and Wishing early recovery to your Aunt.
