Teenager Looking Through Window

Study shows that teens’ brains aged faster in the first year after the pandemic. Stress may also be to blame

A new study has shown that the brains of American teens have undergone a physical change during the Covid-19 epidemic, leading to accelerated aging.

After the first year of the pandemic, the young participants reported experiencing more severe anxiety and depression, as well as what scientists refer to as internalized problems. This is a term that means they felt sad, had low self-esteem, fear, and difficulty regulating their emotions.

Numerous studies have shown that the pandemic has hurt teens’ and teenagers’ mental health. They were removed from their school and away from their family and friends, and forced to deal with the fear and uncertainty that the coronavirus brought. Many parents lost their jobs. Covid-19 has caused the deaths of millions of grandparents and parents.

This study was published in the journal Biological Psychiatry Global Open Science on Thursday. It examines the changes in brain function that are caused by stress and anxiety.

This research is part of a larger study that sought to understand gender differences in depression in adolescents.

They set out eight years ago with a plan for MRI scans of 220 children ages 9-13 every two years. When the pandemic struck, the team had already completed two sets of scans. They were unable to begin scanning again until 2020.

The team realized that it would be fascinating to examine the impact of this stressful event on children’s brains after their research was stopped. They could make this comparison using pre-pandemic scans.

Researchers matched children from the same demographics, including gender, age, and exposure to stress, with their socioeconomic status.

They used MRI scans to calculate the average age of the brain and created a model that combines data from different scans.

Researchers compared the MRI scans from 128 children. During the pandemic, half of the scans were taken before it and the other half at its end in 2020.

The researchers discovered that children who survived the pandemic’s first year had brain ages higher than their chronological years.

The brains of those who had been affected by the pandemic experienced growth in the areas that regulate fear and stress. This is called the amygdala. It also grew in the hippocampus which controls memory access. The cortex, which controls executive function, had seen tissue shrinkage.

Although brain development happens naturally in children, research shows that physical changes can be accelerated when there is significant trauma during childhood.

Research has shown that those who have been exposed to violence and neglect early in their lives can experience faster brain aging.

Ian Gotlib, the lead author of this new study, stated that the research team expected to find problems with anxiety, depression, and internalized issues. Gotlib, a Stanford University psychology professor, said that the pandemic had not been kind to adolescents’ mental health.

They weren’t sure what they would find in the MRI scans.

Gotlib stated, “It’s always fascinating to do research such as this when you don’t know what’s going on.” These effects were fascinating and occurred very quickly.

He said that it was only a one-year shutdown and that we didn’t expect that the brain would feel the effects after such a short period of stress. It is in line with the mental health problems that we are seeing.

He said that it is not clear if the brain changes will have an effect later in life. To track brain development, the research team will scan the same children later. He said that there is a possibility that brain changes in these children could be an immediate reaction to stressors that will eventually normalize.

To see if there was a difference, the team will also examine the 10 children who had Covid-19. Gotlib stated that physical differences are “a little more prominent” in children who have had Covid.

Dr. Max Wiznitzer is the diversion chief for pediatric neurology at UH Rainbow Baby & Children’s Hospital. He said that the brain changes were fascinating, but it’s more important to know if mental health issues persist.

“The anatomy is irrelevant. Wiznitzer, who was not involved in the research, said that it’s the functionality that is important. “The clinical consequence is the functional effect, how the mental health condition functions clinically and how you deal.

Problems such as anxiety and depression can be managed with the right mental health interventions. Wiznitzer said that the brain is capable of reorganization or improvement.

Gotlib asks parents and guardians to remember that even though school and lockdown closures are over, mental health consequences could still be lingering.

If your teenager is experiencing depression, anxiety, or withdrawal, make sure they are receiving the help they need.
