Memory Loss, Ringing Ears
My husband just turned 40. In the last year he has experienced memory loss and has a constant ringing in his ears. He has had a general physical and other than slightly elevated blood pressure he is in good health. He just had a complete thyroid work up as thyroid issues are common in his family and we know his symptoms can be caused by that by those results just came back completely normal.
Any ideas what to look at next?
