Abstract: Have you heard of cognitive stimulation therapy? The London School of Economics (LSE) has carried out research that shows it to be more cost effective than usual care when looking at the cognitive and quality of life benefits for a dementia sufferer. There is also evidence to suggest that it might be more cost effective than dementia medication, say proponents of this relatively unknown therapy. Joanne Knowles is one such advocate who believes in this therapy so much that she voluntarily campaigns to spread its message.
