WHO guidance says cognitive training — structured memory, attention and problem-solving practice — may be offered after 65 with normal cognition or mild impairment. Still, low digital skills, limited access and poor adherence sharply limit who benefits. Guideline Central, summarizing WHO, describes the advice as conditional and based on low-certainty evidence Guideline Central summary. WHO released the second edition on 15 July 2026 as an update to its 2019 edition with wider life-course advice.

What the guideline recommends
The training advice applies to two groups: older adults with normal cognition and those with mild cognitive impairment. Mild cognitive impairment means noticeable memory or thinking change without loss of daily independence. Cognitive stimulation and social-activity programs are listed separately as options to encourage, not strong prescriptions.
Guideline Central, summarizing WHO, rates both as conditional on very-low-certainty evidence. WHO frames these steps with wider risk reduction in its 15 July 2026 news release. It states up to 45% of dementia risk could be prevented or delayed through modifiable-risk action. That total covers cognitive, physical and health-system measures together, not training alone.
Why many stop early
Dose matters, and many users do not reach it. In a JMIR Aging study of 19 adults with impairment, only 32% completed 90 minutes per week, while 68% used it occasionally or stopped JMIR Aging study. The Australian Journal of Psychology reports a similar pattern for home-based computerized training.
Only 25–30% completed at least 66% of sessions, which limited benefit for adults 65 and older. Short, irregular use delivers less practice than tested programs require. Fatigue, boredom, unclear progress and competing health demands can interrupt routines. Without steady sessions, expected gains fade even when the software works well.
Who faces the hardest access gap
Cost and confidence shape access more than interest. A Cureus pilot for economically disadvantaged seniors found only about 2% kept weekly online training. It cited confusing outreach language, limited technology access and low digital literacy.
Age widens the digital gap. In England's study of over 6,000 adults, Lancaster University researchers report regular internet use at 91.1% for ages 65–79 but 65.7% at 80+ Lancaster University analysis. Lack of skills mattered more than lack of access, with education, employment and cognitive ability driving differences.
What can improve follow-through
Match the format to the person, not the reverse. In-person programs, libraries and clinics can reduce tech friction for beginners.
Family help with login, sound, font size and reminders often decides early weeks. Bring current medicines, recent thinking changes and device questions to the next primary-care visit.
- Confirm eligibility: normal cognition or mild impairment, plus vision and hearing needs.
- Choose short scheduled slots, such as 30 minutes three times weekly, with calendar prompts.
- Pair training with social contact, walks and health visits instead of solo screen time.
- Track completed minutes weekly and ask staff to adjust difficulty early.
