Can AI Detect Parkinson’s Disease Early?

June 19, 2024

A groundbreaking study from University College London and University Medical Center Goettingen, which was published in the journal Nature Communications, describes a new blood test that can detect Parkinson’s disease about seven years before any signs show up. Using artificial intelligence (AI), this test looks for certain signs in the blood. This is a big step forward in finding diseases early and getting them treated.

Understanding the Study and Its Findings

Researchers were most interested in people who had Rapid Eye Movement Disorder (iRBD), a disease in which people act out their dreams. About 75% to 80% of people with iRBD will develop synucleinopathies like Parkinson’s. These are diseases that are caused by too much alpha-synuclein protein building up in the brain. Using a machine-learning tool, the test was able to find 79% of people with iRBD who had biomarker profiles that pointed to Parkinson’s. The AI looked at eight blood-based signs and correctly predicted that 16 people would get Parkinson’s disease seven years before they did. Follow-ups with these people over time have proven that the test is valid.

The Potential Impact of Early Diagnosis

The acting editor-in-chief of the Journal of Clinical Parkinsonism and Related Disorders, talked about how the biomarker test could change diagnosis, treatment, and study in neurodegenerative conditions. Dr. Michael Bartl also said that the test not only predicts when Parkinson’s will start, but also finds connections between the disease and biological processes like inflammation and protein breakdown, which could lead to new treatment targets. But, as many experts have said, this new development shows a lot of promise. To fully enjoy its benefits, however, we need to pay close attention to its validation, ethics issues, and clinical integration.

Current Diagnostic Practices for Parkinson’s Disease

At this point, diagnosing Parkinson’s disease requires a combination of brain tests, medical history, and clinical evaluations. Imaging tests like the DaTscan are also used to help make the diagnosis. Even with these steps, there is still a big need to find biological markers that can predict disease and help find it faster and more accurately.

What is Parkinson’s disease?

Parkinson’s disease was named after James Parkinson, who first wrote about it in 1817. Mood problems are caused by the brain’s lack of dopamine release. Oddly enough, losing the ability to smell often comes before motor signs. Most people are diagnosed after they turn 60, but 4% are diagnosed before they turn 50. About 10% of cases are caused by genetics. The sickness can’t be stopped, but it can be slowed down. Tremors are not necessary for identification, despite what most people think. Parkinson’s disease makes it twice as likely to fall, which raises the risk of getting hurt badly. Pesticides and some metals can make you more likely to get Parkinson’s. On the other hand, caffeine may lower the chance.
