Caffeine Level in Blood May Help Diagnose People with Parkinson's Disease
News Jan 04, 2018 | Original Story from the American Academy of Neurology.
Testing the level of caffeine in the blood may provide a simple way to aid the diagnosis of Parkinson’s disease, according to a study published in the January 3, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The study found 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.
“Previous studies have shown a link between caffeine and a lower risk of developing Parkinson’s disease, but we haven’t known much about how caffeine metabolizes within the people with the disease,” said study author Shinji Saiki, MD, PhD, of Juntendo University School of Medicine in Tokyo, Japan.
People in the study with more severe stages of the disease did not have lower levels of caffeine in the blood, suggesting that the decrease occurs from the earliest stages of the disease, according to David G. Munoz, MD, of the University of Toronto in Canada, who wrote an editorial accompanying the study.
“If these results can be confirmed, they would point to an easy test for early diagnosis of Parkinson’s, possibly even before symptoms are appearing,” Munoz said. “This is important because Parkinson’s disease is difficult to diagnose, especially at the early stages.”
The study involved 108 people who had Parkinson’s disease for an average of about six years and 31 people of the same age who did not have the disease. Their blood was tested for caffeine and for 11 byproducts the body makes as it metabolizes caffeine. They were also tested for mutations in genes that can affect caffeine metabolism.
The two groups consumed about the same amount of caffeine, with an average equivalent to about two cups of coffee per day. But the people with Parkinson’s disease had significantly lower blood levels of caffeine and nine of the 11 byproducts of caffeine in the blood. 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. For one of the byproducts, the level was below the amount that could be detected in more than 50 percent of the people with Parkinson’s disease.
In the statistical analysis, the researchers found that the test could be used to reliably identify the people with Parkinson’s disease, with a score of 0.98 where a score of 1 means that all cases are identified correctly.
In the genetic analysis, there were no differences in the caffeine-related genes between the two groups.
Limitations of the study include that people with severe Parkinson’s disease were not included, which could affect the ability to detect an association between disease severity and caffeine levels. Munoz also noted that all of the people with Parkinson’s were taking Parkinson’s medication and it’s possible that these drugs could affect the metabolism of caffeine.
The study was supported by the Japan Agency for Medical Research and Development, Japan Society for the Promotion of Science, and the Japanese Ministry of Education, Culture, Sports, Science and Technology.

Around age 60 I noticed that my handwriting was getting smaller and I was writing faster. I also noticed a small tremor in my right hand. The doctor went over my different symptoms and he suspected I'd either had a small stroke or the beginnings of Parkinson 's disease. After finding a neurologist and some testing I was diagnosed with the beginning stages of Parkinson’s disease. That was 4 years ago. I take Sinimet four times a day to control my symptoms, which include falling, imbalance, gait problems, swallowing difficulties, and slurring of speech,December 2017 our family doctor started me on Green House Herbal Clinic Parkinson’s Disease Herbal mixture, 5 weeks into treatment I improved dramatically. At the end of the full treatment course, the disease is totally under control. No case of dementia, hallucination, weakness, muscle pain or tremors. Visit Green House Herbal Clinic official website w ww.greenhouseherbalclinic .com. I am strong again and able to go about daily activities. This Herbal Formula is Incredible!!

I was diagnosed with Parkinson's disease in my mid to late 40's. I had hand tremors for several years. Gradually becoming worse. I then noticed when I was tired the tremors were worse. I started falling for no apparent reason. I Later had stiffness in my legs and need to walk with 2 canes or a walker. I was very slow getting around. I am now 54 years old. I was forgetful at times and had difficulty expressing myself. I had difficulty swallowing at times. I become tired easily.Now am Parkinson's disease free,after using the Parkinson's disease herbal formula i purchased from BEST HEALTH HERBAL CENTRE for 6 weeks,tremors disappeared,No more legs stiffness,energy increased,walking without cane.
