Blood test may help diagnose Parkinson’s, similar conditions
A highly sensitive blood test accurately identified people with synucleinopathies, disorders caused by the abnormal aggregation of the protein alpha-synuclein, such as Parkinson’s disease. The test, called immunoprecipitation-based real-time quaking-induced conversion (IP/RT-QuIC), detected early-formed alpha-synuclein fibrils — or seeds — that eventually grew into disease-causing aggregates. Microscopic analysis detected…
