I just heard from my neuropsychologist. The results of the testing were that my short term memory is bad and the probably a result of the seizures and Lamotrigine. He gave little hope for the improvement of the memory.
If your husband's seizures are under control, he may be better off. My seizures occurred over a two year period before finally being being brought under control. This was mainly due to not being sent to a neurologist by other doctors.
Give my best to your husband and hang in there like my.wife.has done.
