question: My dad, 53, is diabetic and is on treatment for the same since 5yrs or so recently he had a convulsion for which the ct scan or other tests did not reveal a cause but he had intermittent abdominal pain and diarrhoea a few days before and after the incident.He took the necessary drug given- sodium valproate and is fine now. His doctor ruled out hypoglycemia as a cause and also changed his anti diabetic drug from glimepiride to saxaglipitin What could be the cause for dads seizure? Could it be intestinal worms? Can it occur again?
