The National Dementia Helpline will go online over Christmas to ensure that people in need are not left without the support they need over the festive period.
The helpline will be closed on Christmas Day, Boxing Day, and New Year's Day and so people are being urged to use their computers if they feel that they are in need of help at these times.
A 24 hour, seven day a week online forum has been set up by the National Dementia Helpline to allow users to request advice, discuss their situations and share information with others.
Megan Cruise, advice service manager, said: "It is extremely important that people feel they can access support over the Christmas period."
She acknowledged that the holiday season can be a "very emotional and isolating time" and suggested that people should seek peer support online if they feel that they need to speak to someone at a time when the helpline is closed.
