Document Summary

Processes (cid:315) arousal / alertness / vigilance (cid:315) response inhibition (cid:315) orking memory. Pi equal boys and girls (diagnosed primary/ high school) Highest male/female ratio in normal range of cognitive function. Lowest male/female ratio in lowest range of cognitive function. 70% comorbid for another disorder; 40% for 2+ Visuo-spatial processing / attention to detail / rote. Differences (cid:315) size of right prefrontal cortex (cid:313) cortical slow wave activity (underaroused) (cid:315) erp (low brain activity) (cid:315) blood flow in caudate/frontal lobe (myelinated axons) (cid:315) connectivity between brain regions (cid:313) blood flow to primary sensory cortices. Amygdala - (cid:315) cells / dendritic connections ((cid:315)c/d) Cerebellum initially (cid:315) c/d ; maybe prenatal abnormalities. Cortex - (cid:315) c/d / blood flow / task related activity. Stimulants (cid:313) cortical arousal so no longer seek stimulation to increase arousal for them 75% respond. Tricyclic antidepressants (only in cases where stimulants don"t work) Analysis (shape / reward desired behaviour & extinguish unwanted behaviours)
