Overview
Primary progressive freezing gait (PPFG) is a rare neurological condition where a person's ability to walk becomes progressively worse over time, mainly because of a specific problem called 'freezing of gait.' Freezing of gait means that the feet suddenly feel stuck to the floor, as if glued, even though the person wants to move. This can happen when starting to walk, turning, going through doorways, or in crowded spaces. Unlike freezing seen in Parkinson's disease, in PPFG the freezing is the main and earliest symptom, and it does not respond well to the usual Parkinson's medications like levodopa. PPFG is considered a type of atypical parkinsonian syndrome, meaning it shares some features with Parkinson's disease but is a distinct condition. Over time, people may also develop problems with balance, slow movements, stiffness, and falls. The condition tends to worsen gradually, and most people eventually need a walking aid or wheelchair. There is currently no cure for PPFG. Treatment focuses on managing symptoms, improving safety, and maintaining quality of life. Physical therapy, occupational therapy, and certain assistive devices can help reduce fall risk and keep people as independent as possible for as long as possible. Research into this condition is ongoing, and it remains an area of active scientific interest.
