What is MoCA?
MoCA (Montreal Cognitive Assessment) is a validated reference instrument used to assess cognitive screening. It is most often used for cognitive screening, especially for mild cognitive impairment. Typical administration time is ≈ 10 minutes.
Screening, not diagnosis. A positive MoCA score is not equivalent to a diagnosis. Confirmatory clinical evaluation is required before treatment decisions.
Population calibration. Cutoffs were derived from specific validation populations. Performance can differ in other age groups, languages, comorbid conditions, or clinical settings.
Self-report bias. Patient-reported instruments are subject to under- and over-reporting; clinical context is essential.

Frequently asked questions about MoCA
What does MoCA measure?
MoCA (Montreal Cognitive Assessment) is a validated instrument that assesses cognitive screening. Its primary clinical use is cognitive screening, especially for mild cognitive impairment.
How long does MoCA take to complete?
MoCA typically takes ≈ 10 minutes to administer. Time can vary slightly depending on whether it is self-administered or clinician-led.
Why isn't MoCA scored interactively here?
MoCA requires user certification (paid) to administer since September 2020.
Is there a free alternative to MoCA?
Yes — SLUMS. Free cognitive screen developed by Saint Louis University; comparable sensitivity for MCI.
What is the source paper for MoCA?
Nasreddine ZS, Phillips NA, Bédirian V, et al. The Montreal Cognitive Assessment, MoCA: a brief screening tool for mild cognitive impairment. J Am Geriatr Soc. 2005;53(4):695-699.
Can MoCA replace clinical judgment?
No. MoCA is a structured assessment aid. A score is one input alongside history, examination, and clinical context. Treatment decisions should never rest on a screening score alone.
