Middle-aged people could become the targets of anti-Alzheimer's therapies such as fish oil and curry spice, after Perth researchers found the condition starts to develop up to 20 years before it is diagnosed.
The results come from the Australian Imaging, Biomarkers and Lifestyle study, which tracked 1000 people from Perth and Melbourne to look at factors linked to Alzheimer's disease, which is the major cause of dementia and expected to affect almost one million Australians by 2050.
The researchers found a chemical imbalance in the brain linked to Alzheimer's disease could be detected years before symptoms appeared, suggesting doctors had a large window of opportunity to intervene to halt or delay dementia.They also suggested lifestyle factors such as diet could be important far earlier in life than previously thought.
