Hello and welcome to Healthcare Magic. Thanks for your query.
From the brief description of your symptoms, a likely cause could be a is a transient ischemic attack
). This is a condition where a person can transietly experience neurological symptoms such as headache, paralysis
, etc., which resolve after a brief period. This condition is caused due to a temporary decrease in the blood flow to the brain. Another possibility which has to be considered in this scenario is a migrainous headache (which rarely present with transient neurological symptoms like paralysis).
However considering his age and the major risk factor of smoking
, your father will need a detailed neurological evaluation to rule out any major neurological problems or complications. I would suggest that you let your your father know about this possibility and advise him to see a doctor as early as possible.
Wish you all the best.
