Link Between COVID-19 and Alzheimer’s Risk Unveiled in Monkey Brain Study (Nachrichten)

New research suggests a potential connection between COVID-19 and Alzheimer’s disease, based on findings in aged monkeys. The study reveals a significant increase in spike protein in the brain when amyloid plaques, associated with Alzheimer’s, are present. The combination of COVID-19 and senile plaques amplifies neuroinflammation, leading to disruptions in the blood-brain barrier and increased vulnerability of the entorhinal cortex—a crucial brain region linked to memory processing. The study raises concerns about a potential future epidemic of early-onset dementia, especially among individuals with recurrent COVID-19 infections. The findings emphasize the importance of understanding the long-term neurological impacts of the virus.

Is #COVID19 a risk factor for Alzheimer's disease?

Most primates naturally develop senile plaques (beta-amyloid protein deposits), one of the misfolded proteins known to accumulate in the brain in normal aging and Alzheimer's Disease. Since monkeys can also catch #SARSCoV2 and… pic.twitter.com/g8CfpMs9Y2
