New research has found that common infections, such as urinary tract and respiratory infections, could lead to poorer cognitive performance in middle-aged and older adults. The study analyzed data from over 10,000 adults aged 45 to 65 years old, and found that those who reported having experienced infections in the past year also had worse cognitive scores than those who did not report any infections.

The study’s lead author, Dr. Rebecca Gottesman, stated that “while it has long been recognized that infections can impact cognitive function in acutely ill patients, this study highlights the potential long-term consequences of even mild infections, particularly in middle-aged and older adults.” The study suggests that reducing the risk of infections, through measures such as vaccination and good hygiene practices, may be a way to prevent cognitive decline in later life.

The findings add to the growing body of evidence linking inflammation and infection to cognitive decline and dementia. However, more research is needed to understand the mechanisms underlying this relationship and to determine the potential for interventions to prevent or mitigate cognitive decline.
