Steele-Richardson-Olszewski syndrome, also known as progressive supranuclear palsy (PSP), is a rare neurological disorder that affects brain functions like movement control, balance, speech, and vision. While there are no true synonyms for this particular medical condition, some healthcare professionals may refer to it as Parkinsonism, as it shares a number of symptoms with Parkinson's disease. Other terms that may be used include supra-nuclear palsy, Richardson's syndrome, or postural instability gait disorder. Although there are no known cures for this condition, prompt diagnosis and appropriate treatment may help manage symptoms and improve the quality of life for those affected by the syndrome.
