Medication-Induced Dysphagia in Vulnerable Populations

Risk Factors and Prevalence

Elderly patients with neurological conditions, such as stroke, Parkinson's disease, or dementia, taking multiple medications face compounded risk from both disease and iatrogenic factors, with the American Geriatrics Society recommending careful medication review 1, 2, 3
Advanced age and presbyphagia make elderly patients particularly vulnerable to medication effects, with 16% of independently living 70-79 year-olds and 33% of those over 80 having baseline dysphagia, according to the Journal of the American Geriatrics Society 2, 3
Neurological diseases, such as Parkinson's disease, stroke, dementia, or multiple sclerosis, already cause dysphagia in 30-50% of patients, and medications worsen this substantially, as reported in Clinical Nutrition 1, 2, 4

Failure to recognize medication-induced dysphagia leads to serious complications, including aspiration pneumonia, malnutrition, and increased mortality, highlighting the need for prompt diagnosis and intervention, as emphasized by Clinical Nutrition 1, 2, 4
The American Geriatrics Society suggests that do not assume dysphagia is solely due to underlying neurological disease in patients with Parkinson's disease, stroke, or dementia—medications may be contributing significantly and are modifiable 1, 2, 4
