Fibromyalgia and ADHD share some clinical features, and a reduced dopamine function has been proposed for both disorders. Here we found, in a large sample of fibromyalgia female patients, a higher frequency of childhood ADHD antecedent when compared with healthy women. Our data suggest that Fibromyalgia and ADHD have some common etiopathological mechanism.

Clinical ratings, psychophysiological and biochemical measures were taken from 30 depressive patients before and after sleep deprivation of one night. Most patients improved after sleep deprivation. We found signs of activation and stress, without correlation with clinical improvement. The biochemical changes did not correlate with clinical improvement either.
