My Fiance Takes Topamax For His Seizurs. Since He Started

My fiance takes topamax for his seizurs. Since he started having them his temper has increased rapidly fast. And i was recemtly doing my own researcg because we are very low income and cant afford many test. But he has so many of the symptoms that are repated to Laryosphasm disorder. I was just curious if the two of these are highly common in ppl who have experienced most likely a head injury ajd sleep deprivation?
