Parkinson’s is the fastest-growing neurological disorder in the world, with up to 150,000 Australians currently living with the condition. A new Australian study, the largest of its kind, with nearly 11,000 participants has shed light on how Parkinson’s symptoms and risk factors differ for men and women.
The research found that “invisible” non-motor symptoms are extremely common:
65% reported changes in memory and thinking
66% reported pain and dizziness
96% reported sleep disturbances.
It also highlighted important risk factors: 16% had a history of traumatic brain injury, 36% had pesticide exposure, and 33% had worked in high‑risk occupations such as agriculture or petrochemicals. Parkinson’s was 1.5 times more common in men, with women reporting more pain and falls, and men reporting more memory changes and impulsive behaviours.
At Synapse, we recognise the complex links between brain injury and Parkinson’s, and the impact of cognitive and “invisible” symptoms on everyday life. Studies like this help us move towards earlier identification, better support, and more personalised care for people living with Parkinson’s and brain injury.
