There is no universally best dementia screening tool. The best choice depends on the purpose of screening, available time, training, language, education, accessibility, and the person’s preferences.
Mini-Cog: One of the fastest options, often about 3–5 minutes.
MMSE: Widely recognized and studied, but proprietary and less sensitive to some milder changes.
MoCA: Broader coverage, often about 10–15 minutes, with training and licensing considerations.
SLUMS: A free, broader alternative, often about 7–10 minutes, with education-level considerations.
SAGE: Self-administered, which may support privacy and repeated monitoring. However, it still requires appropriate professional follow-up.
AD8 and GPCOG: Can incorporate observations from an informant, such as a family care partner.
Research has not established one tool as universally better than the others. Sensitivity and specificity can vary depending on the population, setting, language, education, culture, and how the tool is administered.
Providers should also consider vision, hearing, motor ability, fatigue, anxiety, technology access, consent, and the person’s preference. Delirium, depression, medication effects, pain, sleep disruption, and functional changes may also affect results.
Self-assessment appears feasible and acceptable for some people, but privacy preference does not guarantee that follow-up will happen. A concerning result requires appropriate follow-up, and a negative result does not end evaluation when concerns remain.
The key question is: What decision will this result inform next?
