Progressive Supranuclear Palsy is medically recognized as Steele-Richardson-Olszewski syndrome, though it is also frequently referred to by the abbreviation PSP. Historical Context and Naming Origins The condition was first formally characterized in 1964 by neurologists John Steele, John Richardson, and Jerzy Olszewski, leading to the eponym Steele-Richardson-Olszewski syndrome, which remains the primary formal synonym in historical literature. Before this definitive description, the symptoms were often misdiagnosed or grouped under broader diagnostic labels like "atypical Parkinsonism" or "Parkinson-plus syndrome," as the condition shares some motor features with Parkinson’s disease but presents with distinct neurological deficits. Current Nomenclature and Classification In modern clinical settings, Progressive Supranuclear Palsy is the preferred term used by neurologists and researchers globally.

Progressive Supranuclear Palsy is medically recognized as Steele-Richardson-Olszewski syndrome, though it is also frequently referred to by the abbreviation PSP.
Historical Context and Naming Origins
The condition was first formally characterized in 1964 by neurologists John Steele, John Richardson, and Jerzy Olszewski, leading to the eponym Steele-Richardson-Olszewski syndrome, which remains the primary formal synonym in historical literature. Before this definitive description, the symptoms were often misdiagnosed or grouped under broader diagnostic labels like "atypical Parkinsonism" or "Parkinson-plus syndrome," as the condition shares some motor features with Parkinson’s disease but presents with distinct neurological deficits.
Current Nomenclature and Classification
In modern clinical settings, Progressive Supranuclear Palsy is the preferred term used by neurologists and researchers globally. This name is highly descriptive: "Progressive" denotes its worsening nature, "supranuclear" refers to the specific brain region affected (the nuclei of the nerves controlling eye movement), and "palsy" describes the weakness that develops. Within medical classification systems, it is officially cataloged as follows:
- Orphanet: ORPHA794
- OMIM: #601104
- ICD-10/11: Classified under G23.1 (Progressive supranuclear ophthalmoplegia)
Why Multiple Names Exist
The presence of multiple names for Progressive Supranuclear Palsy stems from the evolution of clinical neurology. As researchers identified that the disease involved specific tau protein accumulations (tauopathy), the medical community shifted away from purely descriptive, symptom-based labels toward a name that reflects the underlying pathology. While you may encounter "Richardson’s syndrome" in some academic papers—specifically referring to the classic presentation of the disease—Progressive Supranuclear Palsy remains the standard, most widely understood term for patients and clinicians alike. Understanding these synonyms is helpful when reviewing older medical records or searching international databases for the latest research on Progressive Supranuclear Palsy.
