The brains of U.S. teens have physically changed during the COVID-19 pandemic, aging faster than normal, a new study says.

The young study participants also reported more severe symptoms of anxiety, depression and what scientists call internalized problems -- meaning feelings of sadness, low self-esteem and fear and trouble regulating their emotions -- after the first year of the pandemic.

Dozens of studies have found that teens' and adolescents' mental health has suffered during the pandemic. They have been taken out of school, away from their friends and familiar support structures, and had to live with the uncertainty and fear that came with the coronavirus. Many parents lost jobs. Millions of children lost parents and grandparents to COVID-19.

The study, published Thursday in the journal Biological Psychiatry: Global Open Science, is one of the first to look at the physical changes in the brain brought by that the stress and anxiety.

....

The brains that had gone through the beginning of the pandemic had growth in the area that can help regulate fear and stress, called the amygdala, and in the hippocampus, the area of the brain that can controls access to memories. Tissues had thinned in the part of the brain that controls executive functioning, the cortex.

A child's brain changes naturally over time, but research has found that these physical changes can speed up when a person goes through significant adversity in childhood.

Studies have shown that people who are exposed to violence, neglect, poverty and family problems early in life have faster brain aging and can have problems with their mental health later on.
