Hi,
Thank you for posting your query.
Most likely, your dad has symptoms of TIA-
transient ischemic attack. In this condition, the blood supply to the brain is diminished for some time, during which the symptoms occur. Complete improvement usually occurs within a few hours at the most.
Carotid duplex study of the neck should be combined with MR angiogram of the brain.
Aspirin should be continued. I would advise him to postpone his travel for now, till the work up is done.
Please get back if you require any additional information.
Best wishes,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
