A major step forward in the fight against the neurological disease Parkinson’s: researchers have developed an innovative blood test. This test can make a diagnosis long before the first symptoms of the disease appear – up to seven years. “Bild” reported about this.

It uses artificial intelligence (AI) to accurately assess a person’s risk of Parkinson’s disease. The disease is caused by the loss of nerve cells in the brain that control movement and produce dopamine, an important neurotransmitter.

When these cells die or are damaged, it leads to symptoms such as tremors, slow movements and memory problems. Current treatment approaches focus on dopamine replacement therapies to improve sufferers’ quality of life.

The new test should enable earlier diagnosis and treatment. This can help protect important brain cells and prevent symptoms in the first place.

Despite the relatively small study group of 72 people, the results showed impressive accuracy. It has been possible to predict with 100% certainty whether someone will develop Parkinson’s disease – up to seven years before the first symptoms appear.

Professor Dr. Christoph Kleinschnitz, director of neurology at Essen University Hospital, was positive about the new trial: “This trial changes the fact that people at high risk for Parkinson’s disease can now be included in drug trials aimed at preventing symptoms.”

Additionally, high-risk patients can be identified and supported to reduce other risk factors such as environmental toxins or sleep deprivation. Despite having a small research team, Prof. Dr. Kleinschnitz: “There were few patients in the study, but the results were verified in a second control group, so they are certainly reliable.”

The researchers are optimistic and hope to use an AI blood test within two years.
