Cognitive Stimulation Therapy
Cognitive stimulation therapy (CST) is a group program of themed, enjoyable activities for people with mild to moderate dementia; learn what a session looks like, what the research shows, and how to find it.
Last reviewed: October 2026
Cognitive stimulation therapy (CST) is one of the best-studied non-drug treatments for dementia. It's a small-group program where people with mild to moderate dementia meet regularly to take part in themed activities and conversation designed to gently exercise thinking, memory and language in a sociable, enjoyable way.
It isn't a test, a class, or "brain training" on a screen. It's closer to a well-run club with a purpose.
What happens in CST?
The original CST program was developed in the UK and tested in a trial published in 2003. It involved 14 sessions, twice a week for seven weeks, each lasting about 45 minutes, with a small group of people (often around five to eight) and trained facilitators.
Each session typically includes:
- A warm-up, such as a song, a ball game or a chat about current news
- A themed main activity, for example childhood memories, food, word games, using money, faces and scenes, or current events
- A friendly close, summarizing the session and looking ahead
Key principles include:
- Opinions over facts. People are asked "What do you think of this?" rather than "What year was this?" There are no wrong answers.
- Using reminiscence to help with the present, not living in the past
- Respect, inclusion and fun, with activities adjusted so everyone can succeed
- Stimulating language and thinking in many ways: naming, sorting, discussing, planning
Some programs add maintenance sessions once a week after the main course. There's also an individual version that a family member can do at home with a workbook.
What does the research show?
The original trial. In the 2003 study of 201 people with dementia, those who took part in CST improved on standard thinking tests and on a quality-of-life scale compared with those who didn't. The researchers noted that the size of the effect on thinking compared favorably with trials of dementia medicines.
The big picture. A 2023 Cochrane review, an independent, careful summary of the evidence, pooled 37 trials with more than 2,700 people. It found:
- Small, short-term benefits for thinking in people with mild to moderate dementia
- Clinically meaningful improvements in communication and social interaction
- Slight benefits in quality of life, mood and behavior
- No harmful effects reported
The reviewers noted that fewer studies looked at whether benefits last after the program ends, which is one reason maintenance sessions are used.
Guidelines. In the UK, the National Institute for Health and Care Excellence (NICE) recommends that people living with mild to moderate dementia be offered group cognitive stimulation therapy.
What CST can't do
CST doesn't cure dementia or stop it from progressing. Benefits are modest, and they appear mainly while people are taking part. It's best thought of as one part of good care, alongside medicines where appropriate, physical activity and social connection.
How is CST different from brain games?
Brain-training games practice one narrow skill, usually alone on a screen, and the gains tend not to carry over to daily life (see Do Brain Games Work?). CST is broad, social and conversational. It aims to improve overall thinking, communication and well-being together, which is part of why it may help.
Who is it for?
CST is designed for people with mild to moderate dementia of any type who can take part in a group conversation. It's usually less suitable for people in later stages, or for those with severe hearing or vision problems unless adaptations are made.
How to find CST
CST is widely offered in the UK and is spreading to other countries, including the US, though availability varies. Ways to look:
- Ask your memory clinic, neurologist or geriatrician
- Call the Alzheimer's Association Helpline (800-272-3900) or your local chapter to ask about programs near you
- Check with adult day programs, senior centers and memory cafés. Some run CST or similar groups.
- Ask an occupational therapist or speech-language therapist. Some are trained in CST.
When you find a program, it's fair to ask: How many sessions? How big are the groups? Are the facilitators trained in CST? Is there a maintenance group afterward?
Bringing the CST spirit home
You don't need a formal program to use the ideas behind CST:
- Ask for the person's opinions: "Which of these two photos do you like better?"
- Talk about news, music, food and places, not quizzes
- Play simple word or category games together
- Keep it light, positive and failure-free
