Hello!
Thank you for asking on HCM!
Your mother symptoms may be caused by different disorders:
1- An allergy reaction to the drugs she has been prescribed
2- A possible stroke (ischemic or hemorrhagic), causing slurred speech.
High blood pressure is a known risk factor for ischemic or hemorrhagic events in the brain.
3- A peripheral
facial palsy (a damage to the
facial nerve in the left side), but this would also cause a visible left facial asymmetry. A peripheral facial palsy may be preceded by
vertigo.
I would recommend to consult with the GP for a careful physical examination, blood pressure monitoring, a routine
blood test, fasting glucose, liver and kidney function tests and electrolytes.
A brain CT scan may be necessary if a stroke is suspected during the physical examination.
Hope to have been of help!
Greetings! Dr. Iliri
