What will be an ideal response?
- biological risk factors for neurocognitive disorders include genetics
- neurochemical changes in neurocognitive disorders include low levels of acetylcholine, serotonin, norepinephrine, and dopamine
- brain changes in neurocognitive disorders often include neurofibrillary tangles, senile plaques, Lewy bodies, atrophy, and free radicals
- environmental factors may influence neurocognitive disorders, with diets high in antioxidants and fish and low in fat and cholesterol having protective functions
- moderate alcohol use may be related to delirium more than dementia, but aluminum intake may relate to more dementia
- the amyloid cascade hypothesis refers to various brain changes cascading from genetic and environmental factors to produce neurocognitive disorder
- prevention of neurocognitive disorder will likely hinge on diet, exercise, cognitive stimulation, medications, and perhaps, in the future, gene therapy
