I've just discovered that the anti-epileptic drugs i'm taking, suppress my asperger's defects but makes my way of thinking less deeper, what can i do?

Talk to doctor: You could discuss your concerns with your doctor, who would want to know about them. S/he will likely want some examples of what you mean so s/he can understand. Perhaps medication adjustments can be made as needed, to both help your seizure problem and not impinge on your way of thinking.

Talk to your dr: Discussing this with your prescriber is important.Perhaps a lower dose or similar druggist be more optimal.Quite possibly some trial and educated error might yield good results but definately in collaboration with your prescriber.
