The results of a new study conducted by experts at the University Hospital of Geneva, the University of Lausanne and the Department of Population Epidemiology at the University of Geneva were published in The Journal of Neuroscience.
The sample size was 751 individuals and their ages ranged from 50 to 91 years. In addition, factors such as age, gender, education level, presence of depressive and anxiety disorders, cardiovascular system pathologies and family income were also taken into account.
Experts have found that the white matter in the brains of people living in low-income households shows signs of advanced aging. They also had higher mean diffusivity and lower myelin or neurite density, which is associated with poorer thinking abilities. However, participants from more affluent families had good cognitive function despite higher average diffusivity and lower myelination or neurite density.
