A study published in Nature Communications and conducted by researchers at the University of Nottingham analyzed brain scans from nearly 1,000 UK adults and found that the COVID-19 pandemic accelerated brain aging by an average of 5.5 months compared to pre-pandemic data. This accelerated aging was observed not only in individuals infected with SARS-CoV-2 but also in those who were never infected, indicating that factors such as stress, isolation, and loneliness during the pandemic contributed to this effect. The brain aging was more pronounced in men, older adults, and people from socioeconomically disadvantaged backgrounds. Additionally, among those infected with COVID-19, increased brain aging correlated with reduced cognitive performance. Further research highlighted disruptions in the blood-brain barrier and increased inflammation markers in long COVID patients, which may underlie neuropsychiatric symptoms. The findings emphasize the broader health impacts of the pandemic beyond direct viral infection, including mental health and neurological consequences linked to pandemic-related stress and social isolation.
