Many people with ADD and ADHD have concurrent symptoms with other issues. That’s no surprise. If ADD is a non-traditional brain chemistry, then chances are good that there are other non-traditional issues going on as well.
For me, the transition to Fall is always problematic. There is a real disorder called Seasonal Affective Disorder, or SAD (nice) which causes depression-like symptoms or lack of motivation and lethargy in sufferers. It is caused by lack of daylight, more or less, which can be exacerbated when you work in an office with no windows and end up being one of those people that goes to work in the dark and leaves work in the dark too.
The official treatment is to get more light exposure. If you can get out for a walk at lunch or whatever, that can help. Of course, 30 minutes of sunlight isn’t necessarily enough for some people. They make special lightbulbs or boxes of light that are supposed to help as well. The idea is to essentially get your brain enough of the right light to keep it going in the right way.
For myself, I’ve stumbled upon a bit of a cocktail that seems to help me.
I take St. Johns Wort, which I take anyway as a way to help lift the edge off my inattentive / mild depression. Add to that some fish oil and a multivitamin and things seem to stay a little more stable. I take two fish oil capsules at a time, twice a day. They say it takes time for the Omega-3 and DHA stuff to build up in your brain, so you kind of have to keep taking it, not just pop it when you are feeling down.
As for the multivitamin, it can’t hurt, and you should probably be taking one anyway.
Try it out and see if it helps you.
