Detailed Answer:
Hi, thanks for using healthcare magic

Seizures are due to problems with the electrical properties in the brain. It occurs as a result of an imbalance between excitation and inhibitory forces in the nerves in the brain.

There are different causes such as: (1) genetic or family history

(2)trauma to the brain

(3)alcohol use or withdrawal

(4)brain cancer

(5)any inflammatory or degeneration of the brain

(6)infection of the nervous system

(7)side effect of medication

(8) metabolic conditions such as- liver or kidney disease, vitamin deficiency, electrolyte abnormality

These are some of the more common causes. A doctor would likely suggest an EEG to look at the 'electrical ' aspect of the brain, it can help to identify the type of seizure in some cases. Other investigations such as blood tests would also be needed in some cases.
If there is an obvious cause, based on the history and findings on physical examination then treatment would be directed to it.

In some cases, the epileptic fit would not repeat itself if the cause is reversible.

I hope this helps, feel free to ask any other questions
