The role of age in intracerebral hemorrhages.
Review
Overview
abstract
We aimed to identify the role of age in intracerebral hemorrhage (ICH), as well as characterize the most commonly used age cut off points in the literature, with the hope of understanding and guiding treatment. Strokes are one of the leading causes of death in the USA, and ICH is the deadliest type. Age is a strong risk factor, but it also affects the body in numerous ways, including changes to the cardiovascular and central nervous systems that interplay with the multiple risk factors for ICH. Understanding the role of age in risk and outcomes of ICH can guide treatment and future clinical trials. A current review of the literature suggests that the age cut offs for increased rates of mortality and morbidity vary from 60-80 years of age, with the most common age cut offs being at 65 or 70 years of age. In addition to age as a determinant of ICH outcomes, age has its own effects on the maturing body in terms of changes in physiology, while also increasing the risk of multiple chronic health conditions and comorbidities, including hypertension, diabetes, and anticoagulant treatment for atrial fibrillation, all of which contribute to the pathology of ICH. The interaction of these chronic conditions, changes in physiology, age, and ICH is evident. However, the exact mechanism and extent of the impacts remains unclear. The ambiguity of these connections may be further obscured by individual patient preferences, and there are limitations in the literature which guides the current recommendations for aging patients.
