The development of supplementary methods of examination added new insights to observations related to PSP-P. The diagnosis of PSP-P requires the presence of akinetic-rigid predominantly axial and levodopa resistant parkinsonism (A2) or parkinsonism with tremor and/or asymmetric and/or levodopa responsive (A3). There is growing interest in the second most common variant of PSP-parkinsonism predominant PSP-P. The criteria for the diagnosis of PSP, released in 2017, indicate four basic features of the disease-postural instability (P), akinesia (A), oculomotor dysfunction (O) and cognitive and lingual disorders (C), which clarify the interpretation of the disease.

Progressive Supranuclear Palsy (PSP) and Parkinson's Disease (PD), especially in their early stages, show overlapping clinical manifestations.
