Abbreviated Mental Test (AMT) – Free Online Calculator
The Abbreviated Mental Test (AMT) is a short, structured screening tool used by healthcare professionals to quickly assess cognitive function in patients. Originally developed in 1972 by Hodkinson, it was designed to identify cognitive impairment, particularly in elderly patients, in a fast and reliable way. The test consists of ten simple questions, and the entire assessment typically takes less than five minutes to complete.

What Does the AMT Measure?
The AMT evaluates several domains of cognitive ability through its ten questions, including:
Orientation — knowing the current time, date, year, and where the patient is located.
Short-term memory — remembering an address given at the start of the test and recalling it at the end.
Long-term memory and general knowledge — recognizing historical facts, such as the year World War II ended, or identifying a familiar person from a photograph.
Attention and concentration — counting backward from twenty to one.
Each correct answer scores one point. The maximum score is 10. A score of 8 or above is generally considered normal cognitive function. A score between 7 and 4 suggests moderate cognitive impairment, while a score of 3 or below indicates severe impairment and warrants urgent further assessment.
Who Should Use the AMT?
The AMT was primarily designed for use by trained healthcare professionals — doctors, nurses, paramedics, and allied health practitioners. It is commonly used in:
- Accident and emergency departments to assess confused or disoriented patients
- Geriatric wards to monitor cognitive decline in older adults
- General practice settings when dementia or delirium is suspected
- Pre-operative assessments to establish a cognitive baseline before surgery
- Care home settings for routine monitoring of residents
That said, family members and caregivers can also use informational tools like this calculator to better understand what cognitive screening involves — and to decide whether their loved one may benefit from a formal medical evaluation.
How to Use This Online AMT Calculator
Our free online Abbreviated Mental Test calculator is built to mirror the structure of the clinical AMT as closely as possible. To use it, simply work through each of the ten questions with the person being assessed and select whether they answered correctly or incorrectly. The calculator will automatically tally the score and display an interpretation at the end.
A few important tips for accurate results:
Use a calm, quiet environment. Distractions, noise, or discomfort can affect performance and lead to an inaccurate score.
Read questions clearly and at a normal pace. Do not prompt or hint — the test measures unprompted recall.
Record the address at the beginning. One of the ten questions asks the person to recall an address that was read to them earlier. Make sure this step is not skipped.
Do not rush. While the test is brief, each individual should be given a reasonable amount of time to respond before marking an answer as incorrect.
Important Limitations to Keep in Mind
The AMT is a screening tool, not a diagnostic instrument. A low score does not automatically confirm dementia or any other specific condition. Factors such as anxiety, pain, hearing difficulties, language barriers, low education levels, or physical illness can all affect performance and may lead to a falsely low score.
Similarly, a passing score does not rule out early-stage cognitive decline. More comprehensive assessments — such as the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment (MoCA) — may be recommended when deeper evaluation is needed.
Always follow up the results of an AMT with a qualified medical professional. This calculator is provided for informational and educational purposes only and is not a substitute for clinical judgment or medical advice.
