The findings showed that people with Parkinson’s disease had significantly lower levels of caffeine in their blood than people without the disease, even if they consumed the same amount of caffeine. Thus, testing the level of caffeine in the blood may provide a simple way to aid the diagnosis of Parkinson’s disease, the researchers said. “This is important because Parkinson’s disease is difficult to diagnose, especially at the early stages,” Munoz noted. Their blood was tested for caffeine and for 11 byproducts the body makes as it metabolises caffeine. The caffeine level was an average of 79 picomoles per 10 microliters for people without Parkinson’s disease, compared to 24 picomoles per 10 microliters for people with the disease.
