(Thursday, may 5, HealthDay News) - taking birth control pills or hormone replacement therapy may protect against brain aneurysms women later in life, a new study suggests, although a mis neurologist cast doubt on the quality of the research.
Cerebral aneurysm to occur when a blood vessel in the brain weakens and balloons out, which can lead to a stroke hemorrhagic cerebral (or bleeding) if the ship explodes. These types of aneurysms are more frequent among women than men, possibly because the decrease in the female hormones after menopause plays a role in their development, said the authors of the study.
Brain aneurysms are more common after the age of 40 years and are more likely to burst when people are in their fifties.
In the study, Dr. Michael Chen of Rush Medical University Center and colleagues interviewed 60 women who have suffered brain aneurysms and asked about their use of oral contraceptives and estrogen hormone replacement therapy and their responses were compared to those of a group of almost 4 700 other women in the U.S. public.
Women who had brain aneurysms were significantly less likely to have taken oral contraceptives or received hormone therapy, and were also more likely to have entered menopause earlier, according to the report published online may 4 in the Journal of NeuroInterventional Surgery.
Previous research suggested that taking birth control pills decreases the risk of stroke (bleeding) haemorrhagic life. However, women who either start your rules at an early age, have children, or both, face a higher risk.
Because estrogen is important for the repair and maintenance of the walls of blood vessels, a decrease in the female hormone levels is supposed to be the reason for the increase in the risk of the structure of these ships, the authors of the study noted in general information about research.
However, commenting on the study, neurologist Dr. Cathy Sila said research is flawed and its conclusions exaggerated.
Other research is more reliable, noted Sila, Director of the Center stroke & stroke University hospitals case Medical Center in Cleveland. "Doctors are paid in better data," she said, adding that she hoped that the study convincing physicians to change how they prescribe birth control hormone replacement drugs.
Another expert called the finding "interesting", but it was a study.
"[This] deserves an additional investigation, in a large group of women" said the Dr. David j. Langer, Director of stroke research at the institutes of neuroscience Cushing, part of the North Shore-LIJ health system in Manhasset, New York, "no doubt"", women maintain a higher risk of cerebral aneurysm to men and the connection to hormone differences between men and women can be a contributing factor in this preference", he said.
"Whenever published studies such as this one must be careful in drawing general conclusions, but the results support more research in this area", said Langer. "One question, could be would it be that the incidence of hypertension and smoking was in this group of 60 women and how that compare with the greatest control group"?
In a press release of the editor of the journal, the authors of the study stated that, according to them, that their findings add to the understanding of how the brain aneurysms develop and progress and can stimulate new treatments for patients who have an aneurysm or are at risk of developing a. Current methods of treatment include the control of blood pressure, quitting smoking and possibly surgery to try to prevent future failure.
