Non-motor manifestations in ALS patients with tracheostomy and invasive ventilation

Introduction: This study aimed to investigate non-motor manifestations in amyotrophic lateral sclerosis (ALS) patients with tracheostomy and invasive ventilation (TIV) and their relevance to disease progression. Methods: Sixty-seven ALS patients with TIV were enrolled, and followed-up prospectively. The patients were classified at the final evaluation into two subgroups according to the duration of TIV use or disease stage measured by communication impairment. We identified non-motor manifestations and investigated their frequencies and differences across the stages. Results: The non-motor manifestations were macroglossia (22.4%), unstable blood pressure (38.8%), hypothermia (26.9%), dysuria (50.7%), and hyperglycemia (12.1%). These manifestations occurred significantly more frequently in patients with TIV ≥5 years than in patients with TIV <5 years, and more in patients with severe communication impairment than in those with preserved communication ability. Discussion: Non-motor manifestations are observed at a high rate in ALS patients with TIV, and are possibly related to disease progression. This article is protected by copyright. All rights reserved.
