Most of patients with a neurodegenerative disease will develop swallowing impairments (dysphagia) during their disease progression (up to 80%- 100% in Parkinson disease and Amyotrophic Lateral Sclerosis).~Dysphagia is associated with serious clinical complications, particularly regarding loss of life quality, insufficient medication intake, malnutrition, dehydration, and aspiration with subsequent pneumonia, which is the leading cause of death in this population.~Early detection and measurement of dysphagia trough validated and standardized procedures plays a fundamental role in the clinical practice. Clinical assessment by a speech language pathologist (SLP) can provide early identification of dysphagia and its severity and direct clinical decision making.~The English version of the Clinical Assessment of Dysphagia in Neurodegeneration (CADN), represents a rapid and valid clinical assessment tool for dysphagia in neurodegenerative population.~Currently, there is no validated tool in Italian specific for the clinical assessment of dysphagia in neurodegenerative disease with strong psychometric characteristics.~The present study aims to translate and validate the Italian version of CADN in neurodegenerative population.~The study will be carried out in two phases:~Forward and back translation~Validation process
