Why study genes to understand Parkinson’s?

We still don’t know why people get Parkinson’s. Which is why current treatments can only be about easing symptoms. The condition often affects people very differently and at different ages, which makes us suspect there are a variety of underlying causes. One benefit of studying human genetic variation is the discovery and understanding of the contribution genes make to both healthy processes in the brain but also what changes may occur that lead to diseases such as Parkinson’s. Understanding these processes enables us then to develop new treatments and medications that can intervene in advance of any symptoms and potentially prevent damage to brain cells. The aim of understanding the causes is to ultimately find a cure.
