The specific aim of this study is to try to discover the diagnostic accuracy of SleepImage technology for detecting respiratory failure in patients with MND. Importantly, this research project is not about NIV, it is about what method can most efficiently decide when to start NIV.
To do this we'd like to collect data about you and your breathing from the SleepImage device when you come in for your routine overnight sleep study. We will compare this against the data that we would collect anyway.
Patients aged 18 and over with a Neurologist confirmed diagnosis of ALS
Patients with known respiratory disease
Unstable cardiac disease, stable hypertension or ischaemic heart disease
Current NIV use
Inability to give consent (expected ~15% due to frontotemporal dementia)
