Document Summary

Amaral: injected these antibodies in monkeys who developed behaviours characteristic of autism. 50% of 4 year old mothers believe that their child has it. Zametkin: adults who have been diagnosed with adhd had reduced metabolisms in brain regions involved in self regulations of motor functions and of attentional systems. The symptoms of adhd are similar to the behaviours of those with frontal lobe damage. Prefrontal abnormalities were found when adolescents with adhd perform tasks that require inhibiting motor responses. Greater impairments in performance on the tasks are associated with abnormal activation of these prefrontal regions. There are differences in the basal ganglia, which is involved in regulating motor behaviour and impulse control, in the brains of some. Adhd across the life span: diagnoses are given when 5 or 6 year old kids enter socially structured environments. Many preschoolers that have adhd behaviour are normal. Between 30 to 80% of those with adhd continue to show symptoms throughout adulthood.
