✓ Peer-reviewed alzhub usefulness score 52 out of 100. Cognitive tests and assessment

Topic: Risk, prevention and care in population studies

Objective We report the development and validation of an MDS-based cognitive index, the MDS Cognition Scale (MDS-COGS), by evaluating it against two popular dementia rating scales, the Global Deterioration Scale (GDS) and the Mini-Mental State Examination (MMSE). Participants Two hundred nursing home residents. Measurements Each study participant was assessed on the GDS and the MMSE by trained medical students.

Key findings

Why it matters

This study developed and validated the MDS Cognition Scale for identifying and staging nursing home residents with dementia, assessing 200 residents against the Global Deterioration Scale and the Mini-Mental State Examination. It is a cognitive assessment instrument and does not treat, cure or prevent Alzheimer's disease.
