Objective: To review the contents of the nursing diagnosis of Impaired Verbal Communication in patients with Amyotrophic Lateral Sclerosis. Method: For the review of this diagnosis we used the integrative review. The 21 selected articles were submitted to a careful concept analysis for the definition of the diagnostic concept and review of its elements. Results: It is recommended, in addition to a new definition for the diagnosis of Impaired Verbal Communication, the incorporation of twelve Risk Factors, the maintenance of three others and the relocation of a Defining Characteristic for Risk Factor. It is also recommended the incorporation of nine Defining Characteristics and the modification of the nomenclature of the other three that already make up the NANDA-I. Conclusion: The content review process subsidized a clarification of the chosen concept, contributing to a future refinement and improvement of the study diagnosis and its components present in NANDA-I.
