Tears can be used to diagnose Parkinson’s disease

WASHINGTON: American scientists have discovered that tears may hold clues to whether someone has Parkinson’s disease, according to a preliminary study that will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018.

“We believe our research is the first to show that tears may be a reliable, inexpensive and noninvasive biological marker of the Parkinson’s disease,” said the paper’s author Mark Lew from the Keck School of Medicine of the University of Southern California in Los Angeles.

Lew said the research team investigated tears because they contain various proteins produced by the secretory cells of the tear gland, which is stimulated by nerves to secrete these proteins into tears.

Given that Parkinson’s can affect nerve function of the brain, the research team hypothesized that any change in nerve function may be seen in the protein levels in tears, Lew said.

They got tear samples from 55 people with Parkinson’s and compared with tear samples from 27 people who did not have Parkinson’s but who were the same age and gender. Tears were analyzed for the levels of four proteins.

Researchers found differences in the levels of a particular protein, alpha-synuclein, in the tears of people with Parkinson’s compared to controls.

“Knowing that something as simple as tears could help neurologists differentiate between people who have Parkinson’s disease and those who don’t in a noninvasive manner is exciting,” said Lew.

“Because the Parkinson’s disease process can begin years or decades before symptoms appear, a biological marker like this could be useful in diagnosing, or even treating, the disease earlier,” said Lew.

More research now needs to be done in larger groups of people to investigate whether these protein changes can be detected in tears in the earliest stages of the disease before symptoms start.

    My husband will be 81 years old next month and was diagnosed with Parkinson’s disease 13 months ago. his main symptom were and rigidity or stiffness of his right-hand side.he also had some difficulty writing. The original diagnosis was confirmed three months later by a second neurologist. He was on one tablet of pramipexole (Sifrol), 0.25 mg three times a day. Four months ago his neurologist added Biperiden, 2 mg. he takes half a tablet of Biperiden three times a day. Since the original diagnosis, his stiffness has slowly increased. He lost touch with reality. Suspecting it was the medication I took him off the Siferol (with the doctor’s knowledge) and started him on PD natural herbal formula we ordered from GREEN HOUSE HERBAL CLINIC, I spoke to few people who used the treatment here in Canada and they all gave a positive response, his symptoms totally declined over a 6 weeks use of the Green House Parkinson’s disease natural herbal formula. He is now almost 81 and doing very well, the disease is totally reversed! (Visit their website www . Greenhouseherbalclinic . com) I am thankful to nature, herbs are truly gift from God.
