ADHD Testing Facts
Testing for ADHD involves a number of screening tools, full history and physical, self-tests, observations, and other neurocognitive evaluations. There is no currently accepted blood test or radiologic test for the disorder, though recent studies suggest that there may be some biomarkers (lab tests) and recently the FDA approved the use of an electroencephalogram (EEG) device to assist in the diagnosis and treatment of ADHD. There is some disagreement amongst researchers and clinicians regarding the cost-effectiveness of the technology.
Symptoms and Signs of ADHD
Attention deficit hyperactivity disorder (ADHD) is a behavioral disorder associated with difficulties with attentiveness, impulsivity, and hyperactivity. There are several subtypes of the disorder that include varying expressions of the symptoms. Attention deficit disorder (ADD) is considered an inattentive predominant subtype.

The diagnosis and treatment of ADHD is well established and is based on observations and subjective reports by the affected children, parents, teachers, and physicians.
