Continuing CST improves quality of life; and improves cognition for those taking AChEIs.

These results demonstrate that CST improves cognition and quality of life for people with dementia including those already on AChEIs. Older age and being female were associated with increased cognitive benefits from the intervention. Consideration should be given to aspects of CST, which may enhance the benefits for people with dementia who are male and those younger than 80 years.

Continuation of CST is likely to be cost-effective for people with mild-to-moderate dementia.
