Caffeine

Caffeine is perhaps one of the most thoroughly studied and widely used forms of self-medication among people with ADHD. In animal studies, caffeine consistently and significantly improved memory and learning.1 Meanwhile, a review of human studies found similar positive cognitive benefits, including increases in the following:
� Alertness
� Attention
� Working memory
� Mood and motivation
� Reaction time
The doses that provided the optimal benefits for ADHD patients were typically between 200�400 mg. That�s roughly two to four cups of coffee.
