What are some potential causes of seizures?

• A. Only congenital epilepsy.
• B. Causes can be congenital (epilepsy) or due to an acute problem in the brain (fever, stroke, head injury).
• C. Caused solely by metabolic disturbances.
• D. Caused only by brain tumors.

Answer: (B)

Seizures have multiple potential triggers, not just one category. They can come from a congenital tendency to epilepsy, or from acute problems in the brain that suddenly disrupt electrical activity. For example, fever can push neuronal activity over the threshold in children, leading to febrile seizures. An acute event like a stroke or a head injury damages brain tissue and irritates neurons, causing abnormal discharges that produce seizures. The other ideas are too narrow because seizures aren’t limited to congenital epilepsy alone, nor to metabolic disturbances alone, nor to brain tumors alone—any of these scenarios, in the right context, can cause a seizure.
