Three‐Objects‐Three‐Places Test: Association with Alzheimer’s Disease Biomarkers

The Three‐Objects‐Three‐Places Psychological Test (3O3P) assesses episodic memory and has been developed to screen for Alzheimer’s Disease (AD). To perform the test, the clinician shows the patient three objects and hides them in three separate locations. The patient is later asked what the objects and hiding places were, and which object was hidden where, producing a score out of 9. The aim of this study was to investigate if 3O3P scores were associated with common AD biomarkers to test its potential efficacy in detection of AD pathology, and how these associations compared with other common AD neuropsychological tests.
