An update on sleep disordered breathing in spinal cord injury

Sleep disordered breathing (SDB) is a direct consequence of tetraplegic spinal cord injury (SCI), is highly prevalent in both tetraplegia and paraplegia, and is associated with worse daytime functioning and reduced quality of life. Despite this, most people with SCI are undiagnosed and untreated for the disorder. This narrative review summarises research from the last 5 years on the epidemiology, pathophysiology, and consequences of SDB in SCI, as well as the current approaches to screening, diagnosis, and treatment of SDB in this population.

Previous research predominantly focussed on SDB in tetraplegia, however recent studies have established that people with paraplegia also experience substantially higher prevalence than the general population. SDB risk screening questionnaires are not helpful because SDB in SCI is so prevalent, and questionnaires alone cannot exclude true negative cases. Alternative treatments, such as mandibular advancement devices, are feasible and likely effective, and alternative care models may improve rates of diagnosis and access to treatments.

Recent research into SDB in SCI has identified novel, emergent themes, however researchers must collaborate more to achieve sample sizes that can deliver impact in this relatively rare population.
