I'm 65 and found out about the ADHD at age 63. Thats why my nursing career was destroyed - I was fired from approx 15 jobs - Now I'm retired but still have to work 3 shifts a week - never worked anyplace long enough to get a pension. I was diagnosed by 5-6 therapists with depression. It did not occur to any of them that I had ADHD. I just went on Medicare last Friday - I will be going to a therapist soon and be able - for the first time to - discuss all my problems related to this disorder ( had no med. insurance for almost 2 years).
