[Adroddiad Gohebydd Guan Shuping / Taipei]Stanford University in the United States published a research report on the 1st, highlighting the fact that the comparison of adolescent brains before and during the outbreak of Wuhan pneumonia (new coronavirus disease, COVID-19), is true. Those who had experienced the global pandemic The brains of young people in the epidemic prevention and control barrier were found to show signs of premature aging.
The British “Guardian” reported on the 1st that the researchers studied 81 teenagers in the United States before the outbreak, November 2016 and November 2019, and 82 teenagers during the period of the outbreak between October 2020 and March 2022. Brain Magnetic Resonance Imaging (MRI) done by humans, comparing the brain scan images of 64 people with the same factors such as age and sex, that the physiological changes in the brain during puberty, such as thinning cortical and the growth of the hippocampus and amygdala, adolescence in the epidemic The group were all older than the pre-epidemic group, which means that the developmental stage of the brain of the former has accelerated, in other words, their brain has accelerated get old

“The differences in brain aging Around 3 years, given that the (anti-epidemic) lockdown was less than a year, we did not expect such a big increase.”
The research report highlighted the fact that the subject of the research analysis was a representative sample of young people in the California Bay Area, The intention was originally to study the impact of stress on mental health during adolescence, but later symptoms such as anxiety and worry were also assessed . . Epidemic groups self-reported experiencing more mental health problems, including more anxiety, worry, and internalizing.
Golib said the study’s findings echo some other studies that look at the impact of the pandemic on adolescent mental health.
However, it is not clear whether the poorer mental health seen in the study is due to faster brain ageing, or whether premature brain aging in adolescents is a good thing or a bad thing. “In older adults, these brain changes are often associated with cognitive decline, but it’s not clear what that means in adolescence,” Golib said. But he said it was the first time brain changes that appear to be related to stress had been shown to coincide with mental health problems during the pandemic.
Michael Thomas, a cognitive neuroscientist at Berbeck College, University of London, who was not involved in the study, pointed out that the Stanford study confirmed that young people suffer from increased anxiety and depression during the epidemic, but it still hard to understand the size. brain structure the effect of differences in behavior on current or future behaviour, and the effect is not necessarily negative.
