I have some memory problems occasionally and it is usually with verbal communication, sometimes I can't remember some of the words I was going to say and I have to pause and think of a different word or change my sentence...so I am not such a great communicator verbally these days...I can still type fine since I can pause long enough to find the words and so I use email a lot so I can communicate clearly.

These memory problems started at the same time as my MG symptoms so I would say that they are directly related, but I don't understand how.

I am only taking Mestinon for my MG.

Vitamins, mostly Vitamin B-12, seem to help my memory troubles, but nothing makes it go away completely. Maybe I have a vitamin/mineral deficiency that is causing this, but nothing confirmed.

Sorry your son is having memory problems, it is no fun.
