Could A Dopamine Gene Be the Answer to a Longer Life?

Posted on: September 16, 2013

A study published in the Journal of Neuroscience found that a version of a gene coding for a receptor for the brain chemical dopamine was 66% more common among people who lived to be 90 or older than among a group of younger people who were otherwise similar.  The variant leads to a weaker response to the neurotransmitter, lowering the activity of the dopamine system that is responsible for generating feelings of pleasure, desire and reward, as well as for regulating movement.
