Document Summary

Attention-deficit/hyperactivity disorder (adhd): persistent age-inappropriate symptoms of inattention, hyperactivity, and impulsivity that are sufficient to cause impairment in major life activities. Inattentive: not focusing on mealtime demands and behaving carelessly. Adhd: no distinct physical symptoms, identified by varying characteristic behaviors. 1902: believed symptoms arose from poor inhibitory volition and defective moral control . Early 1900s: wide-spread compulsory education = self-controlled behavior = focus on adha. 1917-1926: encephalitis (brain inflammation) & brain injuries = brain-injured child syndrome. 1940s-1950s: no evidence of brain damage = minimal brain damage and brain dysfunction (mbd) 1950s: adhd referred as hyperkinesis: poor filtering of stimuli entering the brain: led to hyperactive child syndrome. 1970s: argued that hyperactivity, deficits in attention and impulse control were also primary symptoms. Categories are oversimplification: each dimension includes many distinct processes, two dimensions are closely connected. Difficultly during work/play, cannot focus on task/follow instructions.
