People with mild cognitive impairment (MCI), a doctor-diagnosed change in memory or thinking, can track activity under the 2026 WHO dementia guideline without self-diagnosing. WHO says physical activity should be recommended for adults with normal cognition and may be recommended for adults with MCI.
WHO published the second edition on 15 July 2026, updating the 2019 edition, according to the WHO announcement. It found up to 45% of dementia risk could be prevented or delayed. The guideline applies to adults living without dementia, including adults with normal cognition and adults with MCI.

What did WHO recommend for activity?
The Royal Australian College of General Practitioners, summarizing WHO, reports activity should be recommended for normal cognition and may be recommended for MCI, in the RACGP summary. Should signals a strong recommendation. May signals a conditional recommendation.
For a reader with MCI, may means activity is worth discussing rather than starting alone. A GP can consider heart health, balance, medicines, and current ability. That talk keeps exercise safe and personal.
What weekly target can you log?
Adults can track the WHO activity target of at least 150-300 minutes of moderate aerobic activity or 75-150 minutes of vigorous activity weekly, according to the BJSM summary of WHO guidance. Add muscle-strengthening on 2 or more days.
Limit sedentary time each day. Use minutes and counts, not memory scores. A notebook, calendar, or phone log works.
- total active minutes for the week, plus number of sessions
- length of each walk, bike ride, swim, or dance session
- strength days, daily steps, and breaks from sitting
- sleep, blood pressure, social time, and thinking activities
Why not track test scores?
The Alzheimer's Association says MCI is a clinical diagnosis based on a doctor's judgment, described in the Alzheimer's Association MCI page. The exam uses medical history, family or informant input, and functional assessment. It also uses cognitive testing and physical exams.
No single test can diagnose MCI alone. Home puzzles, apps, or score changes cannot confirm or rule it out. Tracking behavior avoids false reassurance and needless worry.
What are the limits and next step?
UN News, reporting the WHO guideline, notes activity lowers risk at population level but does not guarantee prevention for any person. The evidence for MCI-specific benefit was only conditional. Your result will depend on many health factors.
MedicalXpress, reporting the WHO guideline, notes there is no cure or widely accessible treatment, so WHO frames prevention as the most effective strategy. People worried about memory should see a GP for evaluation. Keep logging activity while waiting for that visit.
