Parkinsonism is associated with speech dysfunction. The study evaluates the abnormalities in articulatory planning, execution and their correlation in Parkinsons disease (PD), Multiple System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP) with the BOLD activation pattern, to understand the speech deficits in these disorders.
