Document Summary
Persistent pattern of inattention or hyperactivity-impulsivity that affects functioning or development, symptoms present in 2+ settings, and negatively affects social, academic, or occupational functioning. Several symptoms must be seen before you"re 12. Behavioural observations: continuous performance test (cpt) Xs and os per second) you have to press a button every time a specific stimulus or sequence like x or x then o so differentiate between the letters fast. Outcome determined by: # of correct responses so pick all xs, # of fail to respond to correct stimulus/omission so pick os over xs, # of incorrect response to correct stimulus/commission error. Assess ability to keep attention at fast rate stimuli is presented. Neurological abnormalities: reduced frontal lobe (high function thinking), basal ganglia (involuntary movement) and cerebellum (balance and coordination) means less metabolic activity. Executive functions (ef: ability to control behaviour (through wm), emotions, arousal, inner speech, and communicate and analyze problems, people with adhd have delayed or impaired ef.
