In the concluding episode Vicky continues on her journey to discover the true extent of music’s power in combating dementia. With the choir still glowing from their first public performance in front of a handful of family and friends, Vicky announces that in a matter of weeks they are going to perform again, only this time it will be at the Royal Concert Hall in Nottingham - in front of 2,000 people. Long before they get there, the very real challenges faced daily by the choir threaten to derail the entire project. Working with some of the country’s leading experts, Vicky and the choir also take part in a series of scientific experiments. Joining Dr Lauren Gascoyne from the University of Nottingham’s imaging centre, choir members Julie, Maureen, Mick and Chris take part in a world-first experiment with a cutting-edge scanner. Research has suggested that when people with dementia listen to music the communication pathways in their brains that are damaged can function as normal. So our four willing volunteers are scanned, to see how music affects their brains. Ahead of the final show, the choir come together, try to keep the nerves at bay and put on the performance of their lives. Our Dementia Choir with Vicky McClure - Thursday 8.00pm on BBC One.
