Excerpt:
Differential diagnosis of PD from other parkinsonian disorders, such as Essential Tremor (ET), Multiple System Atrophy (MSA), Corticobasal Degeneration (CBD) and Progressive Supranuclear Palsy (PSP), can be clinically challenging, particularly during the early disease stages. There is no definitive biomarker for PD or for other atypical neurodegenerative parkinsonian disorders during life. This FOA seeks to better fill these scientific gaps.
