The Barchester Healthcare Foundation has donated £10,000 to the south-west branch of the Huntington's Disease Association.
The cheque was presented at the foundation's annual general meeting on Saturday April 14th by Chris Vellenoweth, vice chair of the Barchester Healthcare Foundation.
The money will be used to secure the Regional Care Advisory Service in Devon and Cornwall, supporting 600 Huntington's disease sufferers.
"We are delighted that the foundation was able to contribute so much to support the association.
"It enables us to reach so many more people within the two counties who are affected by this disease. Myself and all those at the Huntington's Disease Association are very grateful."
Val Baggott, general manager at Kernow House and supporter of the grant, said: "At Millaton Court we work closely with the Huntington's Disease Association and welcome their support for the 27 residents we care for.
"We hear so often from the families here of the value they get from the Regional Advisory Service which is a great source of information, advice and support."
The Barchester Healthcare Foundation was set up to provide grants which make a difference to the lives of older people and adults with disabilities.
