痴呆是脑血管病的常见后遗症,作者以往对缺血性卒中后3个月的患者随访时发现有26.3％表现为痴呆。而缺血性卒中后易发生痴呆的危险因素尚不明确。一般认为,引起脑缺血缺氧的疾病可加重痴呆,形成低灌注痴呆。作者通过前瞻性研究来确定缺血缺氧(HI)性疾病是否为卒中患者发生痴呆的独立因素。 Dementia is a common sequelae of cerebrovascular disease. In the past, 26.3% of the patients were followed up for 3 months after ischemic stroke, showing dementia. The risk factors for dementia prone to ischemic stroke are not yet clear. Is generally believed that the disease caused by cerebral ischemia and hypoxia may aggravate dementia, the formation of hypoperfusion dementia. The authors used prospective studies to determine if hypoxic-ischemic (HI) conditions are independent of dementia in stroke patients.
