OBJECTIVE: Impaired neuropsychological performance involving abstraction-flexibility, memory, motor function, and attention has frequently been reported in schizophrenia as well as in attention deficit hyperactivity disorder (ADHD).

This study represents an attempt to compare groups of adolescents with schizophrenia and ADHD on a comprehensive neuropsychological test battery. Such a comparison affords the opportunity to ascertain differences in the degree, profile, and specificity of impairments.

The ADHD research studies noted here all look at the functional neurology of ADHD, or how the brain of a person with ADHD functions differently than the brain of a person without ADHD.
