ORPHA:75567Clinical syndrome
Also called PPFG
What it is
Primary progressive freezing gait is a rare, heterogeneous, progressively incapacitating neurodegenerative disease characterized by freezing of gait (usually during the first 3 years), later associating postural instability, eventually resulting in a wheelchair-bound state. Other features may include mild bradykinesia, rigidity, postural tremor, hyperreflexia, speech disorder and dementia. The disease is unresponsive to dopaminergic treatments.

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
