Thank you for choosing health care magic. You have not provided the detailed information about your father seizures. Usually neurophysicians recommend observation for the first episode of seizures. But if there is any recurrence then patient may need investigations and treatment. Usually such patients will be investigated with CT scan
head, EEG( electro enceohalo gram). If the seizures are because of some structural lesion in the brain it needs specific treatment related to that. Simply ignoring the seizures is not a good thing as it may lead to complications ( accidents,Hypoxix ischemic encephalopathy
in continuous seizures because of lack of oxygen
supply to brain) . So I advise you to visit a neurophysician and get the complete work up done.
