ICD-11 code : L2-6D8;
Preferred Label : Dementia;
ICD-11 definition : Dementia is characterized by the presence of marked impairment in two or more cognitive
domains relative to that expected given the individual's age and general premorbid
level of cognitive functioning, which represents a decline from the individual's previous
level of functioning. Memory impairment is present in most forms of dementia, but
cognitive impairment is not restricted to memory (i.e., there is impairment in other
areas such as executive functions, attention, language, social cognition and judgment,
psychomotor speed, visuoperceptual or visuospatial abilities). Neurobehavioural changes
may also be present and, in some forms of dementia, may be the presenting symptom.
Cognitive impairment is not attributable to normal aging and is severe enough to significantly
interfere with independence in an individual's performance of activities of daily
living. The cognitive impairment is presumed to be attributable to an underlying acquired
disease of the nervous system, a trauma, an infection or other disease process affecting
the brain, or to use of specific substances or medications, nutritional deficiency
or exposure to toxins, or the etiology may be undetermined. The impairment is not
due to current substance intoxication or withdrawal.;
