Delirium in stroke acute

Abstract

Background: The delirium is a serious neuropsychiatric disorder and one of the most frequent complications in the hospital. The incidence of delirium after stroke ischemic or hemorrhagic, has been reported in up to 48% Delirium may be the clinical presentation of a stroke, or may occur as a complication. Objective: Determine the presence, severity and correlation of delirium in patients with ischemic stroke acute. Material and methods: Prospective study of longitudinal cohort, studied 162 patients diagnosed with ischemic stroke, The diagnosis of delirium was conducted according to the criteria defined by DSM-V and Confusion Assessment Method for the intensive care unit (CAM-ICU). Results: A total of 162 patients were evaluated, the mean age was 74.94 (8.92) years, male with 50.31% (n = 82). Vascular risk factors were hypertension 79.75%, dyslipidemia 23.31%, diabetes 34.36%, previous stroke 25.77%, dementia 10.43%, and previous delirium 2.45%. The presence of delirium was 20.25% (n = 33). Compared patients with or without delirium, in hospital days was 9.21 (12.5) vs 4.22 (3) days, the mortality of 29.2% vs 12.8% (P < 0.0001) and functionality as measured by modified Rankin Scale 3.2 vs 2.9. Conclusion: Delirium is a frequent complication and is associated with increased mortality and hospital stay, but most statistical studies would be needed to clarify the incidence and precipitating and predisposing factors in delirium associated with stroke.
