The TACIT Trial: TAi ChI for people with demenTia

The ancient form of gentle exercise known as Tai Chi has been shown to be a great way to improve a person’s health and wellbeing. However, little is known about how it can benefit people with dementia. This study tested the benefits of Tai Chi for people with dementia and their informal carers’ health and wellbeing.

A team of researchers led by Dr Samuel Nyman at Bournemouth University have finished the study and published their key results in a scientific journal article:

A plain English summary of these results is available in a flyer (pdf 374kb), and a video abstract of the research can be viewed below.
