Hi my mother has been taking lamotrigine, carbomazepine for the past 15 years, she suffers seizures . She started taking namenda 2 years ago, now she can not consentrate, she is suffering confussion, dizziness, loss of memory, I can not talk to her because it seems like if she has no idea of whats going on. It is like if she lose it completely. I m wondering if this is due to the comlbination of this last medication?
