SIR – This year, 100,000 more people will develop dementia. As a patron for the Alzheimer’s Society since 2006, I have met many carers and people with dementia, and I know how devastating it can be for the person with the condition as well as their loved ones – it is so important to know that support is out there.

On Friday and Saturday, May 27 and 28, the Alzheimer’s Society and Alzheimer Scotland have the opportunity to raise £350,000 to help fight dementia – and need your help. In fact, we need 10,000 volunteers to help us!

Please join our team collecting money during The BIG collection at Tesco stores in Bradford and across England, Scotland, Wales and Northern Ireland. It couldn’t be easier – you can choose a store near you, and donating three hours of your time will be an enormous help.

The Alzheimer’s Society and Alzheimer Scotland are Tesco Charity of the Year.

If you can spare a few hours to collect, get in touch by calling 0845 6787678 – and ask your friends and family to support this important cause.

If you can’t help this time, you can find out other ways to get involved at alzheimers-tesco.org.uk .
