Dear friend, welcome and thanks for entrusting your query here at HCM !
Your father seems to have vertebral artery
occlusion and hence treated with short term heparin- a blood thinner.
Strocit is citicholine and may help the brain. But the mainstay of treatment is aspirin
Is he on antiplatelet like aspirin?
I can not opine without detailed history, MRI reports and clinical testing, detailed medicine list that he is on.
Please upload all these here so that I can opine precisely.
I would advise to act on your neurologist's advice till then.
Watch for any new paralysis
, imbalance, tingling
, decreased level of consciousness.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries.
Thank you and Good luck !
