Introduction
Neurological diseases of diverse central and peripheral origins have a profound impact on swallowing. Among them, particular emphasis is placed on those caused by secondary effects and most frequently observed during the human aging process.
Although dysphagic conditions arise from distinct factors, they share common clinical characteristics that tend to result in dysphagia, with aging representing a fertile ground for its development.[1]
Malnutrition, dehydration, and aspiration pneumonia negatively affect the health of individuals with oropharyngeal dysphagia, exerting a deleterious impact on their quality of life. Moreover, medical complications resulting from dysphagia may increase healthcare costs and length of hospital stay.[2] [3] [4]
In this context, this editorial aims to highlight the neurodegenerative causes of dysphagia, emphasizing aspects already described in the literature that should be considered in Alzheimer's disease (AD), Parkinson's disease (PD), Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS), Dementia with Lewy Bodies (DLB), and Huntington's disease (HD). The objective is to draw attention to and contribute to improvements in the swallowing process and, consequently, to the quality of life of individuals affected by these conditions, in pursuit of excellence in human health.
