Actual (reported)To enhance our capacity to correctly choose the appropriate medication for ADHD patients on the first try based on the presence of a particular variant of a gene that could be identified on a laboratory test. It is hypothesized that patients with Attention Deficit Hyperactivity Disorder (ADHD) who have failed to respond to methylphenidate medication, but do respond to amphetamines, have a higher than expected incidence the allelic variants of the SNAP 25 gene associated with ADHD, and mutations of the dopamine system genes DRD1, 2, 4, 5 and dopamine transporter and COMTand MAOA.
