A study by the University of Pennsylvania in the United States identified different ways of doing things in the human brain It collapses over the years. To do this, they analyzed 50,000 brain scans. who revealed five different forms of brain atrophy linked to aging and the onset of neurodegenerative diseases.
He The human eye cannot see the subtle changes between the five patterns.identified them using machine learning technology, to do this they trained an algorithm to which they showed scans of 1,150 healthy people between the ages of 20 and 50 and 9,000 healthy people of that age with cognitive impairment.
Individual biological traits, such as being more prone to diabetes or other diseases, or patterns related to alcohol and tobacco consumption affect certain forms of aging. In addition, the condition of other organs affects brain aging.
The head of the group of scientists, Christos Davatzikos, warns that this would not allow us to “talk about treatments in the near future”. “This work helps us understanding the heterogeneity of brain aging in general, which is caused by several possible underlying pathologies, including Alzheimer’s disease and Parkinson’s disease, as well as factors related to cardiovascular and metabolic health,” explains the expert.
“For now, the most immediate benefit may be seen in clinical trials, which benefit from the recruitment of profiles with more homogeneous profileswhich allows us to detect more subtle treatment effects with smaller samples,” the researcher explains.
