Evaluating a brief intervention for mealtime difficulty on older adults with dementia

Area of Science:

• Gerontology
• Neuroscience
• Clinical Nutrition

Background:

• Dementia, including Alzheimer's disease, often leads to significant mealtime difficulties for older adults.
• These challenges can negatively impact nutritional status and quality of life.
• Existing interventions may not fully address the specific needs of individuals with dementia during mealtimes.

Purpose of the Study:

• To evaluate the effectiveness of a spaced retrieval intervention in alleviating mealtime difficulties in older individuals with dementia.
• To assess the impact of the intervention on nutritional status and body mass index.
• To explore the feasibility and potential benefits of spaced retrieval for this population.

Main Methods:

• A single-case study design with an ABA structure was employed.
• Data were collected using the Edinburgh Feeding Evaluation in Dementia scale, Mini Nutritional Assessment, and Body Mass Index.
• Realist and economic evaluations were conducted to understand intervention effectiveness and cost-efficiency.

Main Results:

• The spaced retrieval intervention led to a reduction in mealtime difficulties for most participants.
• Six out of eight completers maintained improvements in phase A3.
• Nutritional scores showed similar positive patterns, with moderate to large effect sizes observed.

Conclusions:

• Spaced retrieval therapy is a potentially effective intervention for reducing mealtime difficulties in older adults with dementia.
• The findings suggest that this method can positively influence nutritional outcomes.
• Further large-scale, multicenter trials are recommended to validate these results across diverse populations.
