Clinical Context
The Abbreviated Mental Test Score (AMTS) is a rapid screening tool for cognitive impairment, often used to screen for confusion, delirium, or dementia in hospital settings.
- Score < 7 or 8: Suggests cognitive impairment (delirium or dementia). Further assessment (e.g., MOCA, 4AT) is recommended.
- Limitations: Can be affected by language barriers, aphasia, or hearing impairment.
