he pathophysiology of ADHD is unclear and there are a number of competing theories.[87] Research on children with ADHD has shown a general reduction of brain volume‚ but with a proportionally greater reduction in the volume of the left-sided prefrontal cortex. These findings suggest that the core ADHD features of inattention‚ hyperactivity‚ and impulsivity may reflect frontal lobe dysfunction‚ but other brain regions particularly the cerebellum have also been implicated.[88] Neuroimaging studies

The end result is a deprivation in the brain of an important neurochemical‚ called dopamine. Dopamine helps regulate movement‚ and its loss leads to increased tone‚ rigidity‚ and slowness of movement. Lack of dopamine results in the symptoms associated with Parkinson disease .Approximately 50‚000 Americans are diagnosed with Parkinson disease every year. 95% of those diagnosed are over 50 years old

attained through numerous different activities. Dopamine is a key chemical in the human body’s process of reward sensation. This chemical release can be measured by neuroscientists through brain monitoring equipment. Though there is some debate over the degree to which dopamine is involved in the chemical process of reward‚ it is a widely known and accepted fact that during the sensation of reward‚ the human body produces excess amounts of dopamine (Berridge 4).
