Though family history of epilepsy
is significant, what is important is whether or not you have similar episodes in the past.
refers to involuntary jerky movement of a part or whole of the body. This is a benign, harmless condition which occurs especially during a sleep. Presuming you are perfectly alright preceding and following the episode, you need not be concerned.
However, if these episodes are recurring or if you had any physical disturbances during the episode, you would need to get investigated. The primary set of investigation that is needed is radio imaging of brain (CT/MRI
scans) and EEG. Management will be needed if any of the tests reveal significant abnormality.
Hope this answers your query.
Wish you good health.
