Study shows how the pandemic may have affected teens’ brains

The pandemic’s effects on teenagers were profound — numerous studies have documented reports of issues with their mental health, social lives and more.

Now, a new study suggests those phenomena caused some adolescents’ brains to age much faster than they normally would — 4.2 years faster in girls and 1.4 years faster in boys on average, according to the study published Monday in the journal Proceedings of the National Academy of Sciences.

By being the first to contribute details on aging differences by sex, the study adds to the existing body of knowledge provided by two previous studies on the Covid-19 pandemic and accelerated brain aging among adolescents.

“The findings are an important wake-up call about the fragility of the teenage brain,” said senior study author Dr. Patricia K. Kuhl, the Bezos Family Foundation Endowed Chair in Early Childhood Learning and codirector of the Institute for Learning and Brain Sciences at the University of Washington in Seattle, via email. “Teens need our support now more than ever.”

Significant socioemotional development occurs during adolescence, along with substantial changes to brain structure and function. The thickness of the cerebral cortex naturally peaks during childhood, steadily decreases throughout adolescence and continues to decrease through one’s lifespan, the authors wrote.

The researchers originally intended to track ordinary adolescent brain development over time, starting with MRIs the authors conducted on participants’ brains in 2018. They planned to follow up with them for another scan in 2020.

The pandemic delayed the second MRI by three to four years — when the 130 participants based in Washington state were between ages 12 and 20. The authors excluded adolescents who had been diagnosed with a developmental or psychiatric disorder or who were taking psychotropic medications.

Remember when Lady Gaga ‘bled’ onstage during her shocking performance at the 2009 VMAs?

Singing about the perils of fame, being dragged out from beneath a fallen chandelier then bleeding to death in front of a roomful of celebrities: Lady Gaga was not shy about making her debut at the MTV Video Music Awards.

The year was 2009 — many will remember it as the year rapper Ye (formerly Kanye West) stage-crashed 19-year-old Taylor Swift and suggested her award for Best Female Video should have gone to Beyonce instead. But never one to be overshadowed, Lady Gaga, then 23, made some pop culture history of her own that night.

Her rendition of “Paparazzi” — lamenting both unrequited love and the sinister effects of hounding tabloids — has gone down in the mists of Gaga legend; not least because a lack of high-quality footage means fans must resort to watching grainy screen-recorded versions circulated on social media.
Over the limited number of pixels, Gaga can be seen at the start of the performance in an all-white ensemble: a bejeweled, asymmetric lace bodysuit and matching cape, thigh-high boots, a feathered Keko Hainswheeler headpiece and strings of glinting pearls. As she staggered back from her piano at the song’s crescendo, however, an audible gasp swept the room as thick blood suddenly appeared to be pouring from her abdomen.

“I’m your biggest fan, I’ll follow you until you love me,” Gaga wailed desperately, her once-pristine outfit now daubed in scarlet. She ended the number suspended above the stage, ‘dead,’ as more blood dripped from her eyes.

“(It) gives me chills every time I watch it,” Olivia Rodrigo told MTV in 2021. “I think Lady Gaga is the best performer of our generation.” The “Drivers License” singer appeared to take notes. At this year’s Grammy Awards, she began to ‘bleed’ from clenched fists while performing her hit “vampire,” spreading fake blood across her arms and neck as the song progressed.
