HELEN Joseph's doctor knew she had Parkinson's when she moved her arm.
"I was taken aback," she said. "I went in for something else and he noticed how my joint moved."
She was diagnosed early, but didn't take medication immediately.
"When I did go on the tablets they worked straight away," she said.
"It really helped me function normally."
Mrs Joseph, 71, lives in her own house in Barney Point, and has maintained her independence.
She said going out and appearing normal in public was important to many sufferers of Parkinson's.
"It can be hard to go outside," she said
"You have to be confident."
On one outing she blacked out in a shop and an ambulance had to be called.
"It takes time to work out how to manage Parkinson's properly but you can do it," she said.
Mrs Joseph eats small regular meals, carries water everywhere and takes her medication daily.
"I eat a lot more now than when I was healthy," she said.
"If I ate then what I do now I would be enormous!"
