The Brown Model of ADD/ADHD From more than 25 years of clinical interviews and research with children, adolescents and adults who have ADD/ADHD, Dr. Brown has developed an expanded model to describe the complex cognitive functions impaired in ADD/ADHD. This model describes executive functions, the cognitive management system of the human brain. Definition The Brown attention-deficit disorder scales (Brown ADD scales) are self-report rating scales that measure symptoms of attention-deficit hyperactivity disorder (ADHD). The scales are normed for four ages groups: primary/preschool (ages 3–7), school-age (8–12), adolescent (12–18), and adult (18 and older).
The Brown Executive Function/Attention Scales include 50 items that assess six clusters of ADHD-related executive function impairments. Versions for children ages 3 to 7 years, 8 to 12 years, teenagers 13 to 18 years, and adults 19 and up. Organizing, Prioritizing and Activating to Work Focusing, Sustaining and Shifting Attention to Tasks. Brown Attention-Deficit Disorder Scales® are a consistent measure of ADD across the life span. Based on Thomas Brown's cutting-edge model of cognitive impairment in ADD, BrownADDScales reliably screen for and explore the executive cognitive functioning associated with ADHD. Age range: 3 through adult.
