HMB440H1 Chapter Notes - Chapter 3: Frontotemporal Lobar Degeneration, Traumatic Brain Injury, Normal Pressure Hydrocephalus
Document Summary
To meet a diagnostic criterion for dementia a person must have evidence of significant cognitive decline and the cognitive decline must interfere with independence in everyday activities. For mild neurocognitive disorder individual must have evidence of modest cognitive decline but the decline does not interfere with everyday activities. Some symptoms may mimic dementia (e. g. delirium or dementia); however, these things can be reversed while dementia cannot. There are types of dementia: ad, vascular dementia, dementia with lewy bodies (dlb), frontotemporal lobar degeneration (ftld), mixed dementia, pd, normal pressure hydrocephalus. Most prominent symptom is memory impairment that disrupts daily life o. In addition, challenges with planning or problem solving, confusion with time or place, changes in mood and personality, etc. As individuals pass through different stages of the disease, individuals" cognitive and functional abilities decline. Accumulation of beta-amyloid is believed to interfere with neuron-to-neuron communication at synapses and to contribute to cell death.
