They are likely to be seizures in themselves, which may stop at that; or they could turn into what you call a full seizure - which I suspect is a tonic clonic.
Epilepsy Action probably has on its website, the descriptions of all the different types of seizures. I suggest you read them, although it’s not always easy to classify seizures, wiithout them having done video telemetry. (An eeg for 24 or 48 hours, while under video filming)
For instance, where a person just goes blank for seconds might be an absence. It’s a minor seizure.
Another type of seizure is called myoclonic, which can be just a jerk of say an arm or leg?
I suggest next time you see a neurologist, to get the results of the EEG, ask for an emergency protocol, if you haven’t got one already - so that you have a set of instructions on when to use midazolam and/or call 999.
A seizure can affect any part of the brain, so it can produce anything we experience - including a change of mood, visual or auditory hallucinations..... Gelastic seizures cause laughing for no apparent reason. DD for instance can get aggressive before, during or after a seizure - but she rarely has tonic clonics; she mainly has focal seizures. I believe people are unconscious during tonic clonics, whereas it’s only impaired consciousness during a focal seizure (or absences).
