EEG shows paroxysmal tendencies

[qqqq123]

I recently went to see a psychiatrist for my depression and anxiety and he sent me to check my T4/TSH levels and EEG. My medical for EEG came saying I have paroxysmyal tendencies and dysrhythmia detected in parieto occipital regions (I don't exactly know if this is the correct translation as I'm not a native english speaker but I guess you kinda know what I meant to say). Anyways, I never had epyleptic seizure and only had mild febrile seizure once when I was ~2 years old. So here is the question: When the nurse was adjusting my electrodes she kinda shook my head to make the stick onto my head and I got dizzy, as I didn't want to open my eyes I got more and more dizzy with my eyes rolling and it took me ~15 seconds to finally stop the spinning and orient my self in space. Could that sensation of spinning cause those irregularities on my EEG medical? I'm seeing a neurologist in a month or so but kinda just wanted to get this out of my head.
