christopher,

Welcome to NeuroTalk.

It sounds like you may be hitting the 40's age where your past sneaks up and tries to kick your butt. It will help if you try to learn the triggers that cause you to have a bad day. Many of us know we need to live life slower and with brain nutrition in mind. There is not much a doctor can do except confirm your symptoms.

I just learned of another ex-motorcross racer who at 42 is hitting the same wall.

Besides eating well, you will benefit from nutritional supplements. I have my regimen posted.

My best to you.
