Dysphagia is a frequent and potentially life-threatening complication in patients with neurological disorders. Swallowing is a complex neurophysiological mechanism regulated by a widespread network of central nervous system regions. The control of swallowing functions requires the integrity of the central pattern generator located in the brainstem, the sensorimotor cortex, the basal ganglia, and the cerebellum, but also peripheral nerves and swallowing muscles. Neurological diseases affecting either central or peripheral components of this system commonly result in dysphagia. Despite its clinical relevance, the management of neurogenic dysphagia remains challenging. While rehabilitative strategies such as swallowing therapy currently represent the main treatment option, emerging evidence suggests that non-invasive central and peripheral neuromodulation techniques may provide adjunctive beneficial effects. Further research is warranted to better define their efficacy, optimal protocols, and long-term outcomes.
