Study details

- Human
Home sleep testing found obstructive sleep apnea in 48 of 74 patients with neuromuscular diseases evaluated at a public university hospital. The study included 11 people with amyotrophic lateral sclerosis (ALS), but it did not report a separate sleep-apnea rate for that group. About 41% of all participants had scores suggesting excessive daytime sleepiness.
Why this matters
The findings support checking for sleep-related breathing problems during respiratory evaluations of people with neuromuscular diseases, including ALS. However, this study does not show that testing improves outcomes or changes treatment for people with ALS.
Limitations and context
This was a prospective study from one hospital with 74 participants, including only 11 people with ALS. The reported sleep-apnea rate covered all neuromuscular diseases together, not ALS separately. The study did not aim to validate a model for early treatment decisions, and the source does not establish whether home testing improved outcomes or directly determined non-invasive ventilation use.
