Although research has found higher rates of depression and suicide to be linked to the thin air of higher elevations, MTN reports on a new study that finds Attenition Deficit Hyperactivity Disorder (ADHD) is significantly decreased in higher altitudes. Researchers believe that a reason for this may be that increased levels of dopamine are produced when people breathe air with less oxygen at higher elevations.  Low levels of dopamine have been found to be associated with ADHD and the increased levels of the hormone found at higher altitudes may serve as a protective factor against the disorder. These findings are important for treatment of ADHD, as we often give people medication that increases dopamine and may want to consider increasing such medications. To read this article in its entirety, click here.
