Dementia is defined as an acquired, persistent, and usually progressive impairment in intellectual function, with compromise in multiple cognitive domains, at least one of which is memory. The deficits must represent a significant decline in function, and must be severe enough to interfere with work or social life for the diagnosis to be formally applied. As the disorder progresses, individuals with dementia often fail to recognize family members, are unable to express themselves clearly and meaningfully, and often undergo dramatic personality changes. Table 30-1 lists some of the more common causes of dementia. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - accessmedicine.mhmedical.com/content.aspx?aid=1102938820 ER -
