The study, published in Stroke, examined the relationship between stress and the risk of subarachnoid hemorrhage, which occurs when the rupture of a vessel causes bleeding into the space surrounding the brain. Up to half of cases are fatal. It is common that people attributed to sudden stress health problems, such as a stroke, said Dr. Craig S. Anderson, George Institute for International Health and the University of Sydney, Australia.
In the case of a subarachnoid hemorrhage, told Reuters Health, it is possible that a sudden increase in pressure produces a rupture in an aneurysm, a weakened area in the wall of an artery. Sometimes this bleeding occurs by a sudden exertion, such as during exercise or sex, said Anderson. But whether stressful life events increase the risk of suffering a stroke.
Anderson’s team interviewed 388 survivors of subarachnoid hemorrhage who had undergone stressful experiences between one month and one year before the stroke. The survey focused on 12 types of situations, such as the death of a relative or friend, loss of job or have suffered a crime. The team then compared the responses with those of a control group of 473 people the same age who had never suffered a subarachnoid hemorrhage. And most of the situations was not related to the risk of bleeding.
But analyzing the experiences of the previous month, two types of stressors, financial or legal problems and “other significant events” – yes were associated with increased risk. 10 percent of the survivors said they had a financial or legal problem the month before the bleeding, as opposed to 4 percent in the control group.
But in considering factors such as hypertension, smoking and alcohol consumption, the relationship between these stressors and the bleeding was only “marginally” significant. There was also an association between the occurrence of subarachnoid hemorrhage have been the victim of a crime the previous year (4 percent of survivors and 1 percent of the control group).
On the other hand, the risk of bleeding decreased in those who had had a family member or friend very ill or had an accident the previous year.
That, according to the researchers, is that the study looked at 12 types of experiences, the few that were weakly associated with the risk of bleeding as they were by chance alone.
Stress, Anderson said, it is very difficult to measure for researchers. The study used an approach of analyzing the rates of the major events that often cause psychological stress. Are unknown real individual responses to these situations. Still, “we can say that ‘stressful experiences’ are not an important risk factor for subarachnoid hemorrhage.”
To prevent it, recommended that people focus on preventing or treating known risk factors of cerebral hemorrhage, which include smoking and hypertension.
