Primary progressive freezing gait: case report

Abstract: The clinical features of the primary progressive freezing gait, a rare and distinct neurological entity, have been described in some articles. This paper describes this gait disorder affecting one patient, whose condition's long course provoked no postural instability. As stated in the literature, the pathophysiology of the primary progressive freezing gait still remains unclear, although the lack of response to levodopa therapy suggests a possible involvement of nondopaminergic pathways. Alteration in the vis… Show more

“…Freezing of gait (FOG) is a common symptom of advanced Parkinson's disease (PD) and may be the only or the first symptom of a variety of parkinsonian syndromes, such as progressive supranuclear palsy (PSP), vascular parkinsonism, and normal pressure hydrocephalus 1. Primary progressive freezing gait (PPFG) refers to a gait disorder, in which arrests of gait appear in isolation, without other typical parkinsonian features such as rigidity, bradykinesia, or tremor, and could not be attributed to other neurological conditions 2–6. This is a progressively incapacitating disorder that does not respond or may even worsen with dopaminergic therapies, and no definite treatment is yet available 6.…”

“…El congelamiento que ocurre durante la "fase off" de la EP responde a la levodopa, mientras que los pacientes en "fase on" no presentan esta buena repuesta a la levodopa 4 . Aunque esta condición refuerce la fisiopatología compleja y no definida del FM, la falta de respuesta a la levodopa sugiere posible participación de vías no dopaminérgicas 16 . Otras condiciones también pueden estar implicadas en la génesis de esta afección, así como el FM producido por la incapacidad de generar amplitud normal en la longitud del paso 6 , la marcha descoordinada y asimétrica 1 y alteraciones en la percepción visual 16 .…”
