More than a tremor: the true toll of Parkinson's
Sydney grandfather Roy Hazelwood underwent deep brain stimulation in 2020 to manage Parkinson's symptoms, after years of medication that was becoming less effective. He says the surgery cleared his thinking and restored his confidence at work, though his voice and handwriting have changed. Parkinson's Australia chief executive Olivia Nassaris says non-motor symptoms such as anxiety, depression and apathy are often the greatest hurdles. About 50 Australians are diagnosed each day, and the organisation expects cases to triple by 2050.
