Document Summary
Use the blocks to construct replicas of a model design presented by the examiner. Age has a prominent influence on block design performance. Men tend to do better than women at younger ages, however the discrepancy disappears over time. The right posterior parietal region is implicated in the block design test, lesions to the left parietal don"t seem to have much effect on test performance. Patients with frontal lobe damage appear to display stickiness when performing the task. Relatively preserved in mild to moderate tbi patients. Block design scores of alzheimer patients are typically among the lowest out of all disorders. Low score in the early stages may help to confirm a clinical diagnosis. Patients with neurodegenerative diseases that typically involve subcortical structures and white matter often do poorly on the block design. Investigate perceptual organization and visual memory in brain impaired subjects. The copy task is simply, copying the complex figure onto a sheet of paper.
