Sydney: Two genes tied to protein accumulation in a Parkinson`s patient`s brain can tell how quickly the disease will progress in an individual, says a new finding."Our study shows that these two genes can be used as a surrogate marker to estimate the rate of Parkinson`s disease progression," said Yue Huang from Neuroscience Research Australia (NeuRA), who led the study.Parkinson`s disease is the second most prevalent neurological condition after dementia. It is characterised by the abnormal accumulation in the brain of a protein called synuclein, as well as the loss of dopamine-producing cells in an area of the brain known as the substantia nigra.The loss of these cells causes the symptoms of Parkinson`s, including trembling, stiffness, slowness of movement and a loss of fine motor control, the Journal of Parkinson`s Disease reported.
