Cognitive stimulation therapy for dementia

What the evidence says about cognitive stimulation - structured, enjoyable group activities - for thinking and quality of life in mild-to-moderate dementia.

Cognitive stimulation (CS) gives people with mild-to-moderate dementia a small but reliable boost in thinking, plus benefits for communication and quality of life - with no reported harms.

What it is

Cognitive stimulation therapy is a set of enjoyable, themed activities (discussion, word games, puzzles, music, everyday topics) usually run in small groups. It is designed to gently engage thinking and social connection rather than test or drill.

What the evidence says

A 2023 Cochrane review pooled 36 trials with over 2,700 participants. It found moderate-certainty evidence of a small benefit to cognition at the end of a course of sessions - roughly equivalent to a six-month delay in the decline usually expected in mild-to-moderate dementia [Woods B 2023] .

The review also reported improvements in communication and social interaction, and slight benefits to quality of life, mood, and daily activities. No negative effects were reported. Benefits looked larger when group sessions ran twice a week or more [Woods B 2023] .

The main limit is duration: it is unclear how long the gains last after sessions end. A trial of “maintenance” CST found continued sessions helped quality of life but added no further cognitive gain [Orrell M 2014] .

The WHO mhGAP guideline lists cognitive stimulation among non-pharmacological options to consider for people living with dementia [World Health Organization 2023] .

What CST involves

Cognitive stimulation therapy uses themed, sociable sessions of discussion and activities:

  • Structured group sessions on varied topics.
  • Gentle mental activities and reminiscence.
  • An emphasis on enjoyment and connection.

Why it may help

  • It keeps the mind actively engaged.
  • The social element supports mood and wellbeing.
  • Themed variety keeps sessions fresh.

Bringing the ideas home

  • Discuss news, photos, or past events together.
  • Do enjoyable puzzles and word games.
  • Keep sessions positive and pressure-free.

What it means for daily practice

  • Make it social and enjoyable - conversation and shared activities count.
  • Aim for regularity - little and often, ideally a few times a week.
  • Keep it varied - mix topics, senses, and game types.

On this site, the calm games and Practice steps put this into practice in short, repeatable sessions.
