2012AB Eight-item Informant Interview to Differentiate Aging and Dementia Source Information
AD8: Eight-item Informant Interview to Differentiate Aging and Dementia was developed by researchers at the Knight Alzheimer' s Disease Research Center at Washington University School of Medicine.
AD8 (Ascertain Dementia 8) is used to screen for the probability of a person having a dementia disorder such as Alzheimer's.
AD8 is an Alzheimer's screening test that can be performed at home or in other settings. The 8-item questionnaire is considered an informant-based assessment because the patient's informant (usually a spouse, child, or non-family caregiver) is asked to assess whether there have been changes in the past few years in certain areas of cognition and functioning. These include memory, orientation, executive functioning, and interest in activities.
The Metathesaurus representation of AD8 is extracted from the LOINC release files.
The AD8 is used by caregivers and clinicians.
Metathesaurus Update Frequency
AD8 is a new source in the 2012AB Metathesaurus release. AD8 will be updated in each Metathesaurus release as part of LOINC.
