A Concentration Killer: Study Shows Brain Chemistry Defect Is Key To Attention Deficit Hyperactivity Disorder In Adults

... In the study, the researchers analyzed the brains of 17 ADHD adults withpositron emission tomography (PET). The PET images, which highlighted theactivity of the dopamine-producing enzyme, DOPA decarboxylase, indicate that anabnormality in dopamine production occurs in only one of the dopamine-rich...

Epilepsy Drug Found To Stop Cocaine's Effects In Animals
