Blues over no sure dianosis

I have been married for 29 years to the same wonderful man and he has been sick for the last 2 and 1/2 years. We have been to doctor after doctor, neurologists, many eegs, spinal tap, mris ct scans with no sure diagnosis. He has seizures, tremors, memory loss, spespeech problems etc. His mri shows white multi focal matter disease but we have had no luck with a real name for his illness. He has had head trauma and no luck with his ssi yet. So that is whatI have been going through the last 2 1/2 years and raising a 10 year old, holding down a full-time job and attaining my degree. I keep praying that things will get better as I know they will.
