Attention Deficit Hyperactivity Disorder, Inattention Disorder and Learning Differences are diagnoses made primarily on the basis of a person’s cognitive and emotional past. That is, you don’t get ADHD/ADD, you either have it or you don’t. The evaluation focuses on finding evidence of problems with: attention, distractibility, impulsivity, disorganization, processing and learning. Other subtle manifestations of attentional and/or learning problems, through careful history taking and examination of school report cards, standardized testing results and previous psychological reports are an integral part of the assessment. An evaluation can take from 2 to 6 forty five minute sessions. In some cases, where a person’s history is not clear, it may be necessary to do additional psychological testing. Testing can take from 2-6 additional sessions and includes a written report if requested.
