Dysphagia in Lewy body dementia - a clinical observational study of swallowing function by videofluoroscopic examination.

Londos E, Hanxsson O, Alm Hirsch I, Janneskog A, Bülow M, Palmqvist S - BMC Neurol (2013)

Bottom Line: Twenty-four (92%) of these had a documented swallowing dysfunction on VFSE.Eighty-eight percent suffered from pharyngeal dysfunction.The results have clinical implications and highlight the importance of asking for and examining swallowing function to prevent complications such as aspiration.

ABSTRACT

Background: Dysphagia, which can result in aspiration pneumonia and death, is a well-known problem in patients with dementia and Parkinson's disease. There are few studies on dysphagia in patients with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), especially studies objectively documenting the type of swallowing dysfunction. The aim of this study was therefore to investigate the prevalence, and define the actual swallowing dysfunction according to a videofluoroscopic swallowing examination (VFSE) in patients with DLB and PDD.

Methods: Eighty-two consecutive patients with DLB or PDD in a clinical follow-up program were asked about symptoms of dysphagia. Those experiencing dysphagia were examined with VFSE. Prevalence and type of swallowing dysfunction was recorded.

Results: Twenty-six patients (32%) reported symptoms of dysphagia such as swallowing difficulties or coughing. Twenty-four (92%) of these had a documented swallowing dysfunction on VFSE. Eighty-eight percent suffered from pharyngeal dysfunction.

Conclusions: Almost all DLB or PDD patients with subjective signs of dysphagia had pathologic results on VFSE, the majority of pharyngeal type. This type of dysphagia has not been reported in DLB before. The results have clinical implications and highlight the importance of asking for and examining swallowing function to prevent complications such as aspiration.

Figure 2: Number of individuals with verified swallowing dysfunction divided according to affected swallowing phase.

Mentions: Twenty-four of the 26 patients (92%) with subjective signs of dysphagia had a documented swallowing dysfunction on VFSE (Figure 1). Of these 24 patients with a documented swallowing dysfunction, 23 (96%) had a pharyngeal dysfunction and 13 (54%) had an oral dysfunction (Figure 2). Pharyngeal dysfunction was prevalent in 12 of these 13 patients. The occurrence of the different types of swallowing dysfunctions and severity (total swallowing dysfunction score) was almost equal in DLB and PDD patients and no significant differences were found between the groups (Table 2).
