Senescent swallowing: impact, strategies, and interventions

Area of Science:

• Gerontology
• Clinical Nutrition
• Speech-Language Pathology

Background:

• Oropharyngeal swallowing (dysphagia) risk significantly rises with age due to natural aging processes and increased disease prevalence.
• Age-related anatomical, physiological, and neural changes, termed presbyphagia, reduce functional reserve, increasing dysphagia susceptibility.
• Dysphagia is a common comorbidity in older adults, exacerbated by sensory changes, medications, sarcopenia, and age-related diseases.

Purpose of the Study:

• To review the impact of aging on swallowing function and associated health complications.
• To discuss nutritional considerations, screening methods, and interventions for dysphagia in older adults.
• To evaluate the efficacy of rehabilitation strategies as alternatives to tube feeding.

Main Methods:

• Literature review of age-related swallowing changes, dysphagia comorbidities, and nutritional aspects.
• Analysis of dysphagia screening tools and the implications of tube feeding.
• Examination of intervention strategies, including compensatory techniques and exercise-based rehabilitation.

Main Results:

• Age-related changes and increased disease burden contribute to dysphagia in older populations.
• Nutritional assessment and fluid intake are critical for managing dysphagia.
• Active rehabilitation, focusing on head and neck muscle strengthening, demonstrates compelling evidence for improved swallowing and eating outcomes.

Conclusions:

• While dysphagia poses life-threatening risks, traditional alternatives like tube feeding also carry significant risks for frail elders.
• Behavioral, dietary, and environmental modifications are compassionate and promising alternatives to tube feeding.
• Further research is needed, but current evidence supports active rehabilitation and supportive strategies for managing dysphagia in older adults.
