Purpose: Dysphagia (swallowing difficulties) can greatly decrease quality of life for individuals with dysphagia and can lead to caregiver burden and third-party disability. Support groups have been shown to be effective in improving quality of life in a range of conditions, through allowing individuals to form connections with those with shared experiences and sharing and learning about relevant resources and coping skills. However, no research on the effects of dysphagia support groups on quality of life has been conducted.

Purpose: It is important to pinpoint modifiable factors contributing to reduced dysphagia-related quality of life (QoL) in order to improve treatment outcomes and patient health given that a large proportion of stroke survivors experience dysphagia. The purpose of this exploratory study was to identify the independent predictors of dysphagia-related QoL in community-dwelling stroke survivors.

Method: A sample of 31 adult stroke survivors with dysphagia ( = 62 years; 23 males) and their partners ( = 57 years; seven males) participated in the study.

Dysphagia is commonly diagnosed in patients living with dementia, but we lack understanding of changes in swallowing physiology and the resulting relationship to impairments of safety and efficiency. The purpose of this study was to describe the pathophysiology of dysphagia in a retrospective sample of patients living with dementia. Videofluoroscopy data from 106 adults (mean age: 84) diagnosed with dementia were scored by blinded raters.

Purpose Caregiver burden negatively impacts both stroke survivor and caregiver well-being. Thus, it is important to better understand the individual- and dyadic-level variables that may contribute to dysphagia-related caregiver burden. The aim of this preliminary study was to identify survivor-, caregiver-, and dyadic-specific factors associated with burden in couples experiencing poststroke dysphagia.

The Cobb angle is traditionally used for quantifying the degree of spinal curvature through evaluation of the full spinal cord. When conducting measurements on videofluoroscopy swallowing studies (VFSS), the Cobb angle can measure degree of cervical vertebrae curvature, which may have implications for swallowing. Given that this measure may have utility in dysphagia research, the reliability of this measure taken from C2-C4 and establishing the presence of changes with age were the focus of the current, proof-of-principle study.

Informal caregivers can experience high levels of burden, negatively impacting both the caregiver and care recipient. The presence of dysphagia (swallowing impairments) in care recipients is suggested to contribute to increased caregiver burden. The purpose of this study was to describe the type and severity of caregiver burden experienced by adults caring for community-dwelling older parents reporting symptoms of dysphagia.

Purpose The purpose of this study was to determine if older adults residing in long-term care were able to accurately self-report their swallowing status by comparing subjective complaints of dysphagia and objective methods of swallowing screening. Method Data were collected from 397 residents of long-term care (M = 86.8 years ± 7.

The aging population is rapidly growing, requiring speech-language pathologists to better manage a caseload that includes older adults who have a variety of needs. The purpose of this review is to summarize and discuss the current available evidence that will allow speech-language pathologists to make informed clinical decisions when working with older adults. To facilitate this, this article first establishes an understanding of both normal and disordered swallowing physiology in older adults, including how to differentiate between functional changes to swallowing (presbyphagia) and dysphagia.

Article Synopsis
  • Previous research identified physiological issues linked to dysphagia in dementia patients, highlighting the need for a deeper understanding of its consequences for effective intervention.
  • This study analyzed videofluoroscopy clips from 58 dementia patients to measure swallowing safety and efficiency, focusing on penetration, aspiration, and residue during swallowing of varying liquid consistencies.
  • Findings showed over 70% of swallows were safe, but significant residue in the pyriform sinus increased the risk of penetration-aspiration by 2.83 times when swallowing thin liquids, suggesting a need for further research into the underlying causes of these issues.

Purpose Thickened liquids are frequently used as an intervention for dysphagia, but gaps persist in our understanding of variations in swallowing behavior based on incremental thickening of liquids. The goal of this study was to establish reference values for measures of bolus flow and swallowing physiology in healthy adults across the continuum from thin to extremely thick liquids. Method A sex-balanced sample of 38 healthy adults underwent videofluoroscopy and swallowed 20% weight-to-volume concentration barium prepared in thin and slightly, mildly, moderately, and extremely thick consistencies using a xanthan gum thickener.

With the rapid increase in the elderly population, there is a simultaneous increased need for care provided by family caregivers. Research in the field of head and neck cancer has indicated that caring for patients with dysphagia can impact a caregiver's quality of life. Given that many older adults present with dysphagia, one can assume that their caregivers are equally, if not more greatly, affected.

Many long-term care (LTC) residents have an increased risk for dysphagia and receive texture-modified diets. Dysphagia has been shown to be associated with longer mealtime duration, and the use of texture-modified diets has been associated with reduced nutritional intake. The current study aimed to determine if the degree of diet modification affected mealtime duration and to examine the correlation between texture-modified diets and dysphagia risk.

The aim of this study was to determine the type and extent of caregiver burden uniquely experienced by spousal caregivers of older adults with dysphagia. Using the Round 1 surveys from the National Health and Aging Trends Study and the National Study of Caregiving, we analyzed data on 422 community-dwelling older adults and their spousal caregivers. Approximately 17% of care recipients reported swallowing difficulties.

Article Synopsis
  • This study evaluated the validity and reliability of the International Dysphagia Diet Standardisation Initiative Functional Diet Scale, which measures the severity of swallowing difficulties related to food texture restrictions.
  • Results showed strong agreement among evaluators, but specific scenarios like liquid-only diets revealed challenges, indicating a need for clearer scoring guidelines.
  • Overall, most participants expressed positive feedback and enthusiasm for using the new scale in clinical practice, noting its sensitivity to dietary changes compared to existing scales.

Many studies evaluate dysphagia in elderly patients and compare their swallowing to younger controls to assess the degree of swallowing impairment. Previous research suggests that changes should be expected in swallowing due to aging, and these changes need to be considered when performing swallowing assessments. A systematic review was conducted to elucidate the timing of swallowing in healthy.
