Description
Summary:Abstract Introduction: Sleep apnea (SA) is a sleep disorder with serious health consequences. SA is more prevalent in acquired brain injury (ABI) patients than in the general population. Yet, there is limited research characterizing sleep architecture in ABI patients with comorbid SA during acute recovery. Methods: This was a retrospective analysis of ABI patients admitted for neurorehabilitation and referred for polysomnography (PSG). Of 197 patients referred, 138 received PSG, and 93 had valid results with >240 minutes of recorded sleep. ABI etiologies were traumatic (66.7%), stroke (23.7%), or other (9.7%). PSG parameters examined were: total sleep time (TST); % time in N1, N2, N3, and REM; and Arousal Index (AI). One-way ANOVAs were used to compare none/minimal SA (AHI
