Currently there's no definitive way of identifying Parkinson's before the onset of at least a few symptoms. The risk can be asseseed by family history and checking for certain genetic mutations.
Before any motor symptoms appears there are other prodromal symptoms can appear years before - eg: constipation possibly 20 years before, loss of smell and depression up to 10 years before.
Also there are tests like DaTscans that measure the amount of dopamine transporters in the brain. DaTscan has been successfully used in Europe to separate Alzheimer’s disease from a dementia condition called Lewy Body disease.
DaTscan drug is injected into the bloodstream to assess dopamine containing neurons, which are involved in controlling movement. A gamma camera to take pictures of the brain and a trained clinician can interpret the imaging.

Researchers have developed an AI-powered blood test that can predict Parkinson’s disease up to seven years before symptoms appear. The test analyzes eight blood biomarkers and has shown 100% accuracy in diagnosing the disease.
A team of researchers, led by scientists at UCL and University Medical Center Goettingen, have developed a simple blood test that uses artificial intelligence (AI) to predict Parkinson’s up to seven years before the onset of symptoms.
This breakthrough offers the potential for early intervention and treatment before significant damage occurs in the brain. The team are also hoping to secure funding to create a simpler blood spot test where a drop of blood can be spotted on a card and posted to the lab to investigate if it can predict Parkinson’s disease even earlier than the seven years before the onset of symptoms in this study.
