However, the Syn-One test will be negative if the symptoms are caused by diabetic autonomic neuropathy, medications, or irritable bowel syndrome, among other causes. All three of these conditions will show a positive Syn-One test.
Autonomic dysfunction can be seen in PD, multiple system atrophy, and pure autonomic failure (PAF). Patients with dizziness upon standing due to blood pressure drops (orthostatic hypotension), constipation, abnormal sweatiness, and urinary dysfunction may be experiencing reduced function of the autonomic nervous system, meaning the nerves which control the visceral organs. However, it cannot differentiate between PD and DLB, as both will show positive results on the Syn-One test. The Syn-One test can differentiate between DLB and other causes of dementia such as Alzheimer’s disease and vascular dementia. Syn-One can differentiate between conditionsĭementia with Lewy bodies is a form of cognitive decline (dementia) associated with Parkinson’s-like tremor, slowness, and/or gait issues, often with hallucinations or other behavioral changes. It can also help in cases of slowing and stiffness to differentiate between normal aging or arthritis vs PD. The Syn-One test can thus be useful in differentiating between tremor due to Parkinson’s disease vs other causes of tremor (most commonly essential tremor or medication-related).
5 conditions have abnormal alpha-synuclein After three weeks, we receive a report which notifies us if any phosphorylated alpha-synuclein was found, as well as other information about peripheral nerve health. The biopsy specimens are then sent to a company in Arizona called CND Life Sciences which was founded by neurologists at Harvard Medical School.
Positive syn skin#
This is done under local anesthesia, meaning the skin is numbed, and the biopsy areas heal on their own without stitches and in the majority of cases without scarring. The skin biopsy is performed in three locations: in the skin over the upper back, lower thigh, and lower leg above the ankle. This abnormal form of alpha-synuclein is known as phosphorylated alpha-synuclein. Alpha-synuclein is a protein whose abnormal (toxic) form causes clumping in the nerve cells, eventually causing the brain cells that create dopamine to start dying off, resulting in the symptoms of PD. Specifically, we are performing a simple skin biopsy known as the Syn-One test to look for an abnormal form of the protein alpha-synuclein in the nerves of the skin. Leading-edge diagnostic technology for Parkinson’s diseaseįortunately, your team at the Pacific Movement Disorders Center at Pacific Neuroscience Institute (PNI) has access to leading edge diagnostic technology to improve diagnostic accuracy when faced with a possible PD diagnosis. For example, if a person has arthritis or back pain, they may have slowness of fast finger movements and shuffling, even without a neurodegenerative cause for their symptoms. However, too frequently, aspects of the clinical symptoms and signs can be equivocal, and the diagnosis may be unclear. In most cases, the diagnosis of Parkinson’s disease (PD) is clear based on clinical signs of rest tremor, bradykinesia (slowness or small size of movements), and rigidity.
