: Although dysphagia is an important symptom associated with prognosis in patients with Parkinson's disease (PD), dysphagia tends to be overlooked until swallowing difficulties reach an advanced phase. We assessed dysphagia with videofluoroscopic examination of swallowing in 31 patients with mainly mild or moderate PD. Swallowing problems were observed in the pharyngeal phase in 28 patients, oral phase in 19 patients, esophageal phase in 15 patients, and oral preparatory phase in 1 patient. Therefore, dysphagia in the pharyngeal phase was observed in almost all patients with mild or moderate PD. In contrast, no dysfunction was detected in most patients when screening was conducted via questionnaire or other methods. Assessment of clinical parameters in the present study suggests that latent swallowing dysfunction may be present even in the early disease stage in PD. A future prospective study to follow swallowing functions in a pre-symptomatic phase in PD would be fruitful to find whether swallowing dysfunction is one of the prodromal symptoms.

Dysphagia is very common in patients with Parkinson’s disease (PD) and often leads to aspiration pneumonia, the most common cause of death in PD. Unfortunately, current therapies are largely ineffective for dysphagia. As pharyngeal sensation normally triggers the swallowing reflex, we examined pharyngeal sensory nerves in PD for Lewy pathology. Sensory nerves supplying the pharynx were excised from autopsied pharynges obtained from patients with clinically diagnosed and neuropathologically confi...

Parkinson disease (PD) is a neurodegenerative disease primarily characterized by cardinal motor manifestations and CNS pathology. Current drug therapies can often stabilize these cardinal motor symptoms, and attention has shifted to the other motor and nonmotor symptoms of PD that are resistant to drug therapy. Dysphagia in PD is perhaps the most important drug-resistant symptom because it leads to aspiration and pneumonia, the leading cause of death. Here, we present direct evidence for degener...

Summary Objective: To assess the influence of levodopa on swallowing dysfunction in Parkinson’s disease patients. Methods: A systematic review of the literature and a meta-analysis were performed. All studies referring to levodopa and swallowing dysfunction that provided direct data or data that could be transformed into mean ± standard deviation were considered for analysis. The primary efficacy variables were Oral Transit Time (OTT), Pharyngeal Transit Time (PTT) for both thin fluids and solid...

Gastrointestinal abnormalities in Parkinson's disease (PD) have been known for almost two centuries, but many aspects concerning their pathophysiology have not been completely clarified. The aim of this study was to characterize the oropharyngeal dynamics in PD patients with and without levodopa-induced dyskinesia. Fifteen dyskinetic, 12 nondyskinetic patients, and a control group were included. Patients were asked about dysphagia and evaluated with the Unified Parkinson's Disease Rating Scale P...

Abstract Sporadic Parkinson’s disease involves multiple neuronal systems and results from changes developing in a few susceptible types of nerve cells. Essential for neuropathological diagnosis are α-synuclein-immunopositive Lewy neurites and Lewy bodies. The pathological process targets specific induction sites: lesions initially occur in the dorsal motor nucleus of the glossopharyngeal and vagal nerves and anterior olfactory nucleus. Thereafter, less vulnerable nuclear grays and cortical areas...

We studied 16 patients with Parkinson's disease (PD) with dysphagia and 8 young and 7 elderly normal controls videofluorographically to evaluate the nature of swallowing disorders in PD patients. In 13 patients, abnormal findings in the oral phase were residue on the tongue or residue in the anterior and lateral sulci, repeated pumping tongue motion, uncontrolled bolus or premature loss of liquid, and piecemeal deglutition. Thirteen patients showed abnormal findings in the pharyngeal phase, incl...

Progressive supranuclear palsy (PSP) is a progressive degenerative extrapyramidal disease that often masquerades as Parkinson's disease (PD). Similar to PD, dysphagia frequently complicates the course of PSP. Because there is only one published report characterizing dysphagia in PSP, we reviewed the neurologic features and dynamic videofluoroscopic swallowing function study results in 10 dysphagic PSP patients. Abnormalities during multiple stages of ingestion were recorded in each patient. Unco...

Dysphagia in patients with Parkinson's disease (PD) is most often atributed to pharyngeoesophageal motor abnormalities. In our study of patients with idiopathic PD, attention was focused on prepharyngeal symptoms and motor functions. Using the Hoehn and Yahr disease severity scale, patients were grouped into those with mild/moderate disease [subgroup I (n=38)] and those with advanced disease [subgroup II (n=34)]. Dysphagia symptoms were present in 82% of all patients, but subgroup I patients voi...

We sought to ascertain whether patients with Parkinson's disease without symptoms of dysphagia have abnormalities of swallowing, and to describe the characteristics as seen on clinical examination and videofluoroscopy. Patients with stable Parkinson's disease were interviewed for symptoms of dysphagia and 16 asymptomatic patients were enrolled. Whilst on their usual medication, an examination of facial, tongue and palatopharyngeal musculature was made, and a modified barium swallow performed. Al...
