Study Reveals High Sensitivity and Specificity of Phosphorylated Alpha-synuclein Detection in Synucleinopathies
The study aimed to evaluate the clinical utility of detecting phosphorylated alpha-synuclein in skin biopsies of patients with synucleinopathies. With over 95% sensitivity, the skin biopsies accurately detected phosphorylated alpha-synuclein in patients with Parkinson's disease, multiple system atrophy, dementia with Lewy bodies, and pure autonomic failure. Specificity reached around 97%, highlighting the reliability of this method in clinical practice for diagnosing synucleinopathies.
