new paper published last week supporting a new-ish theory that adhd is potentially a circadian rhythm disorder
not only does the paper demonstrate strong correlations between adhd symptomatology and sleep disturbances, it also suggests a novel adjunct treatment path - intervention studies showed that adhd symptoms can be significantly reduced by advancing the circadian rhythm of study participants (bright light therapy, melatonin, fixed wake/sleep times, exercise)
this paper particularly piqued my interest, as there is some discussion in the scientific community that adhd is an alternative phenotype that has its own evolutionary advantage (hunter vs farmer, popularized by thom hartmann).
if adhd is typically characterized by late sleep times and wake times, it would track with this other evolutionary theory that adhd is a representation of an old phenotype optimized for nomadic hunters. people with adhd have higher attention to detail, sensitivity to change, and impulsivity - offering a significant advantage to nomadic tribal hunting cultures
