Pandemic related isolation accelerated the brain maturation in adolescents, especially in girls
Brain maturation is measured by the thickness of the cortex. It is known that stress accelerates cortical thinning, which is associated with a higher risk of developing neuropsychiatric disorders. A study published in PNAS analyzes MRI data collected from 160 adolescents before COVID-19 and from 130 of them after the measures implemented during the pandemic. The comparison of brain structure before and after reveals accelerated cortical thinning which, measured in terms of equivalent years of brain development, was 4.2 years in girls and 1.4 years in boys.brain maturity
