Document Summary
Type of brain disorders: specific disorders (focal damage): The disorder depends on the area of the brain affected (bullet wounds, strokes): generalized disorders (widespread damage): The disorder affect multiple cognitive abilities (closed head injury, dementing disorders, demyelinating diseases, toxic substances) Quiz 1 what is the term describing difficulties in object recognition without sensory impairments: apraxia, aphasia, agnosia, acalculia. Types of dementias: cortical: co-occurrence of many cognitive deficits including aphasia, apraxia, agnosia, acalculia, visuospatial deficits and memory problems (e. g. alzheimer"s, frontotemporal dementias, More likely to manifest first as personality changes, attention deficits, slowness in cognitive processing, difficulties with tasks requiring strategy (e. g. parkinson"s, huntington"s): mixed: Both cortical and subcortical involvement, patterns of cognitive performance midway between cortical and subcortical types (e. g. vascular dementia, lewy body dementia. ) Dementia incidence: alzheimer"s dementia, impaired memory, impairment in at least one other cognitive domain, impairs social or occupational functioning, gradual onset and continual decline, vascular dementia, dementia with lewy bodies, frontotemporal dementia, parkinson"s disease.
