A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer’s disease-like dementia. The findings, published in Alzheimer’s Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer’s, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.
Reports of neurological complications in COVID-19 patients and “long-hauler” patients whose symptoms persist after the infection clears are becoming more common, suggesting that SARS-CoV-2 (the virus that causes COVID-19) may have lasting effects on brain function. However, it is not yet well understood how the virus leads to neurological issues.
“While some studies suggest that SARS-CoV-2 infects brain cells directly, others found no evidence of the virus in the brain,” says Feixiong Cheng, Ph.D., assistant staff in…
