A recent special study published in the journal “Geriatric Neurobiology†states that in the brains of 239 85-year-old Swedish elderly people (of which 2/3 are females, 104 have dementia and 135 have normal cognition) Examination of the size and status of dementia revealed that there was a close link between the size of the head and the prevalence of dementia. During the study, experts conducted CT scans of the total cranial cavity capacity of the elderly (an important indicator of the size of the brain). The results of the scan can also reveal the presence of white matter lesions, that is, synaptic damage to the brain associated with vascular dysfunction. The final results confirmed that the average intracerebral brain capacity of dementia patients is much smaller than that of normal cognitive patients, regardless of whether men or women. Experts analyzed that this is most likely due to the fact that larger brains have “standby†brain capacity that can delay the onset. In addition, in the event of an unfortunate illness, the smaller the brain volume, the more severe the symptoms of dementia. However, there was no significant difference in brain size between people with dementia-related gene mutations and those who did not. Researchers say this is the first time that a special study has been conducted on whether the brain size of the elderly is related to dementia.
