one way valve survey found that caffeine has the role of protecting the nerve cells in the brain, the small intestine of patient has weak absorption ability for the coffee and others caffeinated diet, so the blood concentration is low, and then appear the nerve injury, and finally result in Parkinson disease.
Before the Parkinson's disease premorbid, the specific nerves will start to decrease. This team strives to develop the method to screen for potential patients by blood tests, and patches that absorb caffeine from the skin.
The features of Parkinson’s disease are decreasing the specific nerve cells in the brain and appear symptoms of trembling hands and feet. It usually diagnoses through the symptoms and images, but it’s difficult to judge at the early stages. If we can make a definite diagnosis through blood test at the early stage, then the examination will be more simplifies and help to start the treatment as soon as possible.
Nobutaka Hattori, a professor at Shuntiantang University, said: "If caffeine can be absorbed from the skin and increase the caffeine content in the blood, perhaps it may prevent or slow the development of disease."
This team noticed that caffeine contained in coffee had a preventive effect on the onset of Parkinson's disease, so they collected the blood of 108 patients and 31 healthy individuals and compared their concentrations of caffeine. The results showed that the patient's blood concentration was only 1/3 that of healthy people, even they take in the same amount of caffeine
