How does the MoCA test detect cognitive decline?
The short answer
The Montreal Cognitive Assessment (MoCA), developed by Dr Ziad Nasreddine in 1996, screens 8 cognitive domains in approximately 10 minutes. A score of 26–30 is normal; 18–25 suggests MCI; below 18 suggests dementia. It detects early Alzheimer's with ~90% sensitivity, compared to ~80% for the older MMSE.
The data
| Domain tested | Points | What is assessed |
|---|---|---|
| Visuospatial / executive | 5 | Trail making, cube copy, clock drawing |
| Naming | 3 | Name 3 animals from pictures |
| Memory (delayed recall) | 5 | Recall 5 words after 5 minutes |
| Attention | 6 | Digit span, vigilance, serial 7s |
| Language | 3 | Repeat sentences, fluency for "F" words |
| Abstraction | 2 | What do a train and a bicycle have in common? |
| Orientation | 6 | Date, month, year, day, place, city |
What it means for you
The Human Benchmark MoCA test is based on this framework. It is the same assessment Trump scored 30/30 on in 2018 and Biden took ahead of the 2024 election. Use it as a baseline now, and retest annually to track trends.

Quick Answer
The MoCA screens 8 cognitive domains in ~10 minutes: visuospatial, naming, memory, attention, language, abstraction, delayed recall, and orientation. A score below 26/30 suggests MCI. It detects early Alzheimer's with ~90% sensitivity - far better than the older MMSE.
