Men’s brain age faster than women, reveals a new study. According to researchers, men are more susceptible to faster brain damage, memory weakening, cognitive impairment and mental diseases like Alzheimer’s and Parkinson’s disease.
For the study, researchers from the Univeristy of Szeged researchers conducted tests over 103 participants including 53 men and 50 women with an average of 32 years. Study authors took the brain scans of every participant and found the difference in sub cortical brain structures between different sexes. Scientists already knew that grey matter (primarily associated with processing and cognition) present in the brain decreases as we age. However, researchers were astonished to note that grey matter decreased at a much faster rate in men when compared to women.
More importantly, the study highlighted that men lose more matter in the part of the brain that manages emotional processing and movement — the caudate nucleus and the putamen volume. Thus, it relates gender and depleting cognitive functioning with age especially abnormal emotional behaviour among old men. In addition, ageing also affects thalamus (brain’s main relay station for passing information around the brain) more in males.
According to researchers, the study will help in understanding the mental disorders at the older age and how to tackle these problems. It is to be noticed that researchers haven’t yet found any treatment for mental disorders like Alzheimer’s that kicks in at older age and the study might yield further insight in the course and prognosis of these disorders.
The study appeared in the journal Brain Imaging and Behaviour.
