- The problem is not so much that we do not know how ritalin works, as that
- we don't know how ADD works. We know that ritalin releases dopamine and
- norepinephrine from nerve endings that contain them. These are generally
- regarded as excitatory neurotransmitters. They generally carry messages of
- an alerting or arousing nature. I would guess ritalin works by alerting or
- arousing. The brain waves of kids with ADD have features of not being as
- alert as most people's are. You can imagine that it might be hard to pay
- attention if your brain is less alert. It might even be depressing,
- especially if you saw people around you paying attention and being alert
- effortlessly while you have to fight to do the same. Ritalin also works
- for narcolepsy, a condition of frequently and involuntarily falling
- asleep. I believe there is some evidence that ADD and narcolepsy might
- tend to run in the same families.
-
- In any case, if ADD results from brain underarousal, ritalin would be a
- logical treatment. Many people with ADD get addicted to adrenalin
- releasing experiences - thrill-seeking. I would suppose they are trying to
- arouse themselves.
-
- Depression is a separate disease. If it occurs with ADD it should be
- treated with antidepressants. Some antidepressants have arousal as a side
- effect and therefore also treat ADD. Desipramine is one.

- Well, enough for tonight . I hope this is helpful.
