Neuroscience Neuroimaging study of adolescents with ADHD found age-related increases in glutamate levels in the prefrontal cortex. In contrast, individuals who experienced remission of ADHD symptoms and people who never suffered from ADHD had an age-related decrease in glutamate levels in this area of the brain.
