The study was to measure the level of alpha-synuclein in the tear of examinees. The tear of patients with Parkinson's disease includes much alpha-synuclein, which is an abnormal type of protein potentially harmful to neurons.
Independent: Testing tears could lead to cheap and effective Parkinson's disease screening
This presentation was conducted at a conference of the American Academy of Neurology. Since their study seems not to have been published, I should be deliberate to jump into conclusion. If their finding is meaningful, it will be great progress in the treatment of Parkinson's disease.
Parkinson's disease causes motor dysfunction as well as several complications. Its cause is considered to be the crippled substantia nigra. But the substantial reason why patients suffer from physical and mental symptoms has not been clarified.
Furthermore, diagnose Parkinson's disease is not easy, for my experience. Depression, anxiety, and hypochondriac thoughts often precede the onset of motor symptoms in Patients. They sometimes need several years before being diagnosed. There are some specific examinations such as DAT brain scan and heart muscle scintigraphy, but they are expensive and invasive. If a teardrop can detect early dysfunction of the patients, they will get ready for the disease without irritation. I hope this innovative finding will be authorized soon.
