Lecturer Shigeki Yamada of the Nagoya City University Institute of Medical and Pharmaceutical Sciences, Assistant Professor Hiroto Kono of the Shiga University School of Medicine, and other researchers from Nagoya City University, Shiga University of Medicine, the University of Tokyo, Osaka University, Tokyo Metropolitan University, Yamagata University, Tohoku University, and Kyoto City. A research group from Rakuwakai Otowa Hospital and Fuji Film found that women's cerebral blood flow is higher than men's, and this tendency is more pronounced in women under 40.
According to Nagoya City University, the research group used high-resolution MRI (magnetic resonance imaging) to image the heads of 22 healthy people between the ages of 92 and 129, and determined the amount of intracranial volume occupied by each brain region. We investigated the ratio, measurements of main arteries, gender differences, and age-related changes.
As a result, the total brain volume was larger in males because the intracranial volume was larger in males than in females, but no difference was observed between males and females in the proportion of intracranial volume.On the other hand, cerebral blood flow was higher in women than in men in all generations, and this tendency was particularly strong in women under 40, who have relatively large brain volumes.
The research group suspects that high cerebral blood flow may be associated with a greater risk of developing migraines and cerebral aneurysms in women under 40, and will continue their research.
It is known that the volume of the brain gradually decreases with age starting from the age of 20, and the required amount of blood flow also decreases.The research group aims to elucidate brain-related diseases such as stroke and dementia by simulating the natural aging of the human brain.
