SALVOS Stores has dedicated September to help raise funds for those with an incurable brain disease.
At the Sutherland Salvos Store a video is being shown to educate people about Huntington's disease.
Manager George Ye said he was happy to have a poster displayed in the store.
Sales staff member Matthew Mellor is also helping raise awareness and there is a collection tin in the store. The disease affects the nervous system and is caused by a defective gene passed from parent to child.
Signs include emotional, cognitive and motor difficulties characterised by jerky movements. Sometimes there is rigidity, loss of body-function control and dementia.
Other symptoms include a slowing down of thought and judgment, lack of awareness of problems and planning difficulties.
Men and women are at equal risk of inheriting the disease, with onset most typically occurring when people are aged in their 40s or 50s.
There are medications to help control emotional and movement problems but there is no treatment to stop or reverse the disease.
In some patients speech is slurred and swallowing, speaking and walking abilities decline while some patients are unable to recognise family members.
Huntington's NSW will hold its first Walk 4 Hope fund-raiser on Sunday at Parramatta Park.
