Reference work entry


Currently it is accepted that the DSM-5 mild neurocognitive dementia (NCD) is derived from research on mild cognitive impairment (MCI). Several labels have been used to categorise non-disabling memory deficits in the elderly. Unlike age-associated memory decline (AAMI), MCI is assumed to have a pathological basis and is at high risk of developing dementia, more than half progressing to dementia within 5 years. MCI has now been expanded to include other cognitive domains and other potential causes like normal ageing, frontotemporal dementia and vascular dementia. Nonamnestic forms may be due to cerebrovascular disease, Parkinson’s disease, Lewy body dementia and frontotemporal dementia amongst others.
