ICD-11 code : 6D80;
Preferred Label : Dementia due to Alzheimer disease;
ICD-11 definition : Dementia due to Alzheimer disease is the most common form of dementia. Onset is insidious
with memory impairment typically reported as the initial presenting complaint. The
characteristic course is a slow but steady decline from a previous level of cognitive
functioning with impairment in additional cognitive domains (such as executive functions,
attention, language, social cognition and judgment, psychomotor speed, visuoperceptual
or visuospatial abilities) emerging with disease progression. Dementia due to Alzheimer
disease is often accompanied by mental and behavioural symptoms such as depressed
mood and apathy in the initial stages of the disease and may be accompanied by psychotic
symptoms, irritability, aggression, confusion, abnormalities of gait and mobility,
and seizures at later stages. Positive genetic testing, family history and gradual
cognitive decline are highly suggestive of Dementia due to Alzheimer disease.;
