Research during the COVID-19 pandemic found that 10-30% of people experienced cognitive impairments like brain fog, which led to the discovery of a specific protein, Interleukin-1 beta , driving these changes. A study by Western and Washington University demonstrated that vaccination might reduce such cognitive symptoms by decreasing brain inflammation and IL-1β levels, showing promise for lessening memory loss impacts.
The research team, including Schulich School of Medicine & Dentistry professor Dr. Robyn Klein, who joined Western from Washington University used rodent models to better understand how COVID-19 impacts cognitive impairment. “We had previously shown that the virus could not be detected in human or hamster brains, and this study also showed that the virus was not invading the central nervous system,” said Klein. The finding means some other mechanism is leading to cognitive impairment.infection increased levels of brain Interleukin-1 beta , a cytokine protein that impacts the immune system.
