For what it's worth Dan, I have similar symptoms (though my public speaking it still there, which is good since that's basically my job!), and last week underwent an Dementia test, and fully passed. To say I'm relived is an understatement! My father had Dementia (the violent kind), my maternal uncle has it, and I'm very concerned about the present and future -- I'm 62. It can seem to us that we're losing it, but sometimes we're the worst judge of these things. Praying for the best for you.
