There are other neurological disorders that bear some resemblance to Parkinson's disease in the symptoms they produce, but on closer examination are distinct from Parkinson's disease on a clinical basis, as well as in the brain changes found. Examples include Progressive Supranuclear Palsy (known as PSP, also referred to as Olszewski-Steele-Richardson syndrome), Multiple System Atrophy, and Cortical Basalganglionic Degeneration. Treatment of these syndromes is with some of the same medications used for Parkinson's disease, although the response is often less satisfactory.
