Interpretation of the AD8 (Adapted from Galvin JE et al, The AD8, a brief informant interview to detect dementia, Neurology 2005:65:559-564) A screening test in itself is insufficient to diagnose a dementing disorder.

BEST TOOL: The AD8 was developed as a brief instrument to help discriminate between signs of normal aging and mild dementia. The AD8 contains 8 items that test for memory, orientation, judgment, and function. Cut points are: normal cognition 0-1; impairment in cognition 2 or greater.

Reciever Operator Characteristics (ROC) curve for AD8. Administered to either the informant (preferable) or the patient, the AD8 has the following properties: • Sensitivity > 84% • Specificity > 80% •Positive Predictive Value > 85% •Negative Predictive Value > 70% •Area under the Curve: 0.908; 95%CI: 0.888-0.925

Screening tests such as the AD8 are insufficient to diagnose a dementing disorder. The AD8 is, however, sensitive to detecting early cognitive changes associated with many common dementing illnesses, including

AD8® Downloads NOTE: The AD8® is a screening test and is insufficient to diagnose a dementing disorder. However, the AD8 is quite sensitive to detecting early cognitive changes associated with many common dementing illness.

Conclusions: The AD8 is a brief, sensitive measure that reliably differentiates between nondemented and demented individuals. Use of the AD8 in conjunction with a brief assessment of the participant could improve diagnostic accuracy in general practice.

The AD8 Dementia Screening Interview (ADS) is a measure used to detect dementia. The ADS is designed to be administered to a knowledgeable proxy/informant, such as a spouse, other family member or close friend.
