The COVID-19 pandemic brought illness and death worldwide, but its impact went beyond just physical health. To control the virus’s spread, governments imposed strict measures like stay-at-home orders, social distancing, and school closures. These restrictions disrupted everyday life for billions, including work and education, and significantly affected mental health, especially among adolescents. Research reveals teen brains aged during Covid lockdowns. Girls were hit harder than boys.
Adolescence is a crucial time for emotional, social, and behavioural development. Teens gain independence, form their identities, and develop self-confidence during this period. However, it’s also when many mental health issues, like anxiety and depression, can emerge. Since females are generally more prone to these disorders, the pandemic’s stress likely had a more significant impact on them.
The lockdowns led to reduced peer interactions and increased isolation, worsening mental health for many teens. Reports show rises in anxiety, depression, and stress post-lockdown, with girls experiencing these issues more intensely than boys. Studies indicate that girls faced more internalizing symptoms, such as anxiety and depression, while boys had more attention problems and lower life satisfaction.
During adolescence, the brain undergoes significant changes. It is highly adaptable and remodels based on experiences. This period sees a decrease in cortical thickness and ongoing processes like myelination and synaptic pruning.
Few studies have looked into how the pandemic affected brain development in teens. Initial findings suggest accelerated brain maturation due to pandemic-related changes. Research shows reduced cortical thickness and increased volumes in certain brain areas for those affected by lockdowns.

This study aims to explore whether COVID-19 lockdowns caused accelerated brain aging, particularly if this impact is more pronounced in girls. Researchers used a statistical method called normative modeling to compare brain development before and after the pandemic. This approach helps identify deviations from typical brain development patterns caused by external factors like the pandemic.
