Hello. I learned today my 64 yr old husband can't say his abc's. He almost finished but left out a couple of letters. I've noticed he has been having difficulty making decisions and depends on me. He gets agitated sometimes and says he doesn't understand something. My husband has been diagnosed with demyelination lesions on the brain and empty spaces. The doctor is going to order another Mir in 6 months. We don't yet know what is wrong.
