Oh gosh noise yes definitely. Supermarkets more when theirs a number of noises happening in the same place.like in shops or noisey places l have tried going to the theatre but l wore ear buds to make you noise less. It worked but l l had a sezurie later when l got home. So noise yes definitely a trigger for me.

i have blown many lights, electrical appliances and computers with seizure activity. Overstimulation of any kind is a trigger for me along with certain pitches of sound.

Yes not sure about the anxiety part other than i have sensory over load so it can happen but I remove myself before it gets to that point most often

My son told me that when he has helped me through my clusters of tonic-clonic he has to turn off tv, ringers on phones. The noise will bring on more seizures. I never knew it could be a trigger. I do have to often lower volume for tv commercials, loud intro for some shows, even have to lower volume for online guided meditations, it has to be low tones in the meditation music.

Yes, I used to love concerts, but now have to be careful of the venues I go to. If I am in a small area it annoys me, I only go to outside arenas now.
Very sudden screaming or screeching makes me cringe also.
