The nature of residual cognitive deficits after out of hospital cardiac arrest (OHCA) is incompletely described and has never been defined against a cardiac control (CC) group. The objective of this study is to examine neuropsychological outcomes 3 months after OHCA in patients in a “middle range” of acute severity. Thirty prospective OHCA admissions with coma >1 day and responsive but confused at 1 week, and 30 non-OHCA coronary care admissions were administered standard tests in five cognitive domains. OHCA subjects fell into two deficit profiles. One group (N = 20) had mild memory deficits and borderline psychomotor deficits compared to the CC group; 40% had returned to work. The other group (N = 10) had severe impairments in all domains. Coma duration was associated with group. Neither group had a high prevalence of depression. For most patients within the “middle range” of acute severity of OHCA, cognitive and functional outcomes at 3 months were encouraging. (JINS, 2011, 17, 364–368)
