Oropharyngeal freezing and its relation to dysphagia – An analogy to freezing of gait

Parkinsonism and Related Disorders, 2020
The pathophysiology of dysphagia in Parkinson's disease (PD) is heterogeneous and poorly understood at present. This study investigated the phenotypes, prevalence and pathophysiology of oropharyngeal freezing (OPF) in PD and its relation to dysphagia.In a prospective study, 50 PD patients were systematically screened for OPF using flexible endoscopic ...

Freezing Gait in Parkinson's Disease

European Neurology, 2008
Freezing is a well-known problem in Parkinson''s disease (PD) and is characterized by an abrupt difficulty in starting or continuing rhythmic and repetitive movements. We utilized a questionnaire in order to assess the occurrence of the freezing gait phenomenon (FG) in a population of 100 consecutive PD patients. Our PD population included 70 males and

Primary progressive freezing gait

Movement Disorders, 1993
AbstractFreezing gait is an incapacitating symptom often observed in patients with Parkinson's disease. It has been less frequently described in association with multi‐infarct state, multisystem atrophies, and normotensive hydrocephalus. In our movement disorder clinic, we have diagnosed (and followed up to 3 years; median, 16 months), 18 patients in ...

Brain imaging in patients with freezing of gait

Movement Disorders, 2008
Freezing of gait (FOG) is a disabling gait disturbance with unknown cerebral pathophysiology. In this review, we discuss the functional brain imaging studies that address gait physiology and pathophysiology of FOG. Radiotracer metabolic studies show basal ganglia-cortical circuitry involvement in different aspects of gait control.

An updated definition of freezing of gait

Nature Reviews Neurology
Freezing of gait (FOG) is among the most debilitating symptoms of Parkinson disease and related disorders, often resulting in falls and a loss of independence. FOG has an episodic and heterogeneous nature that makes it difficult to measure and treat. The field currently lacks a consensus on how to precisely define this phenomenon.

Medical treatment of freezing of gait

Movement Disorders, 2008
Freezing of gait (FOG) is frequently considered as one of the dopamine-resistant motor symptoms of Parkinsonism. Recent studies have clearly demonstrated that the Off-related FOG is improved by levodopa (L-dopa) or entacapone treatment. L-dopa can decrease duration of each FOG episode as well as its frequency.

Freezing of gait in PD

Neurology, 2001
To study the development of freezing of gait in PD.Freezing of gait is a common, disabling, and poorly understood symptom in PD.The authors analyzed data from 800 patients with early PD from the Deprenyl and Tocopherol Antioxidative Therapy of Parkinsonism (DATATOP) clinical trial who were assigned either placebo, deprenyl, tocopherol, or the ...

Freezing of gait in Parkinson’s disease

Journal of Neurology, 2006
Freezing of Gait (FOG) is one of the most disabling and least understood symptoms in Parkinson's disease (PD), and is usually observed in the advanced stage of the disease. FOG can be experienced on turning, in narrow spaces, whilst reaching a destination, and in stressful situations.

Freezing of gait in Parkinson's disease

Neurologic Clinics, 2004
Freezing of gait (FOG) is a highly debilitating, poorly understood manifestation of Parkinson’s disease (PD) that severely limits patients’ mobility. When coupled with postural instability in PD patients, FOG is a common cause of falls, complications of which can occasionally lead to death.

Asymmetry and freezing of gait in parkinsonian patients

Journal of Neurology, 2012
It has been hypothesized that freezing of gait (FOG) in parkinsonian patients (PD) might be triggered by a breakdown in the normal symmetry of gait. In this study, we evaluated the relationship between asymmetry of gait and FOG and the effects of intensive treadmill treatment on asymmetry.
