Strokes in young adults may be caused more often by migraines, other nontraditional factors

Strokes are typically caused by high blood pressure and other traditional risk factors. 但对于35岁以下中风的成年人, migraine headaches and other nontraditional risk factors may be more likely to blame, 新研究发现.

随着人们年龄的增长，这种高风险会降低 这项研究, published Tuesday in the 美国心脏协会 journal Circulation: Cardiovascular Quality and Outcomes.

"There have been many studies demonstrating the association between migraines and strokes, 但据我们所知, this study may be the first to demonstrate just how much stroke risk may be attributable to migraines,第一作者Dr. 米歇尔·勒珀特在一次采访中说 沙巴足球体育平台发布会上. Leppert is an assistant professor of neurology at the University of Colorado School of Medicine in Aurora.

Traditional risk factors for strokes include high blood pressure, 高胆固醇, 2型糖尿病, 吸烟, 肥胖, 缺乏身体活动, 酒精滥用和心脏病. 然而, previous research shows an increase in strokes among young adults who don't have these risk factors and that women under 45 have a higher stroke rate than men, even though they have a lower rate of traditional risk factors.

"We wanted to understand which risk factors were the top contributors to stroke risk among young adults,雷珀特说.

She and her colleagues analyzed health insurance claims data for more than 2,科罗拉多州有600人中风，超过7,800 people who didn't to determine which risk factors were most strongly associated with strokes. 该研究包括18至55岁的人. 大多数中风是缺血性的, which occur when a blood vessel to the brain is obstructed by a clot.

在45到55岁的人群中, nontraditional risk factors were responsible for 28% of strokes in women and 19% in men. 但在18到44岁的成年人中, nontraditional risk factors were significantly associated with the development of strokes, 这种联系在35岁以下的人群中最为明显. 非传统的风险因素包括偏头痛, 凝血障碍, 肾功能衰竭, 自身免疫性疾病和癌症.

35岁以下人群, nontraditional risk factors were associated with 43% of strokes in women and 31% in men. 偏头痛高居榜首, accounting for nearly 35% of strokes in women and 20% in men, 但它对中风风险的贡献随着年龄的增长而下降. Traditional risk factors among the under-35 group were linked to 33% of strokes in women and 25% in men.

Traditional risk factors among adults 35 to 44 contributed to 40% of strokes in women and 33% in men. High blood pressure was the most important traditional risk factor, 随着人们年龄的增长，它的重要性也在增加. Among adults 45 to 55, it was responsible for 27% of strokes in women and 28% in men.

The researchers were surprised to find that nontraditional risk factors, 特别是偏头痛, played such a big role in the development of strokes in young adults, Leppert说.

“他们中风时越年轻, the more likely their stroke is due to a nontraditional risk factor,她说. "We need to better understand the underlying mechanisms of these nontraditional risk factors to develop targeted interventions."
