Essential clinical information regarding PSP symptoms, diagnosis, and management of atypical parkinsonism.
Progressive Supranuclear Palsy (PSP) is a rare, progressive neurological condition that affects movement, balance, vision, speech, and swallowing. It belongs to a group of conditions known as atypical parkinsonian syndromes (or Parkinson-plus syndromes). PSP is often misdiagnosed as Parkinson's disease early on, but it progresses more rapidly and responds poorly to standard Levodopa medication.
PSP is characterized by specific clinical features that distinguish it from standard Parkinson's disease:
A specialized neurological evaluation is necessary for an accurate diagnosis:
Diagnosing PSP relies heavily on a thorough neurological exam, focusing on eye movements, balance, and checking for axial muscle rigidity.
High-resolution brain MRI scans can show characteristic shrinkage (atrophy) of the midbrain, often referred to as the "hummingbird sign" or "penguin sign" on sagittal imaging viewports, helping confirm the diagnosis.
While there is no cure, supportive therapies can improve quality of life and safety:
Speech therapist reviews are essential to check swallowing function. Simple adjustments, such as thickening liquids, tucking the chin while swallowing, and eating soft foods, help reduce the risk of choking or aspiration pneumonia.
Custom physical therapy focusing on balance, gait, and using weighted walkers helps maintain mobility and reduce fall risks.
Prism glasses can help patients look downward, improving their ability to read, eat, or walk downstairs safely.
