Hi,
You need to consult a neurosurgeon or neurologist and get a CT scan of the head for your mother. Discuss with the specialist if an MRI too is required.
What is her age? Is she on any medications currently? Is her blood pressure in the normal range?
Let us know about the reports of the investigations and what her doctor advises.
Post us about how she is doing and if you have any other doubts.
Regards.
it sounds to me that the stroke has affected the veagus nerve,causing this typy of perallesis. & from your mothers age, it should partially recover, given time. all the best to you & your mother. cogs.
