Freezing More than Gait: A Case Report of Freezing of Urination (FOU)‎ in Parkinson’s Disease

الملخص EN

Freezing of gait (FOG) is a disabling phenomenon that is described by patients with Parkinson’s disease (PD).

Not only gait may be involved in the freezing phenomenon, but also some nonmotor symptoms, such as freezing of urination (FOU) in this case.

The characters of urinary dysfunctions in this case resemble “off” freezing: (1) abrupt difficulty in starting or continuing in urination; (2) the urinary dysfunctions fluctuated with medication state; and (3) the urinary dysfunctions could be alleviated dramatically by an external cueing.

Urinary dysfunctions in this patient (and maybe more PD patients) are associated not only with the classical “nonmotor symptoms” but also the freezing phenomenon.

FOU could be a part of the spectrum of freezing symptoms.

The subtypes of the freezing phenomenon will shed light on the PD pathophysiology and clinical treatment.
