Experts say at least 12,000 people living in the Upstate have Parkinson's Disease. The neurological disease affects movement and can cause tremors. There are treatments and medications available, but right now there is no cure.The Greenville Area Parkinson Society, also known as GAPS, wants people to know that free support is available close to home. "We don't just serve the people with Parkinson's. We serve people who are part of their family. We have specific programs for people that are facing the disease in all different progressions, and sometimes caregivers and care partners and adult children are some of the people who need to support the most," said interim executive director Kamber Parker."So many people think that it doesn't affect them, but if you just were to look outside, you probably have a neighbor that has Parkinson's disease and you just don't know it because one of the important factors to remember is that a lot of people don't feel comfortable sharing this diagnosis when they receive it. And a lot of people don't even know they have it," Parker said. Parker said it's important for people to know that symptoms might show up very differently in different people. Some lesser-known symptoms can be restricted facial expressions and reduced blinking, and even handwriting that is getting smaller. Parker said the Greenville Area Parkinson Society offers mentoring, support groups and education. You can learn more here.
