Hi, my maternal grandmother had what was called old age senility, my Mother was diagnosed w Pick s disease (frontal/ temporal lobe dementia) 17 yrs ago I was diagnosed w MS doing very well however i have a 6cm x 7cm lesion that has not repaired it s self my daughter was diagnosed many yrs ago w Common Variable Immune Defiency which can cause lesions in the brain & lungs. I realize there is no connection, there s are all very different diseases but the common thread here is ALL have brain lesions.. Julie Sorry I will not pay for an answer, I m on a fixed income. I will investigate myself. It is something to be looked at.
