Researchers at the University of Duisburg-Essen have published findings indicating a significant increase in stroke risk associated with influenza infection. The study, conducted by researchers from the Medical Faculty and the University Hospital Essen, suggests that acute influenza, in particular, can exacerbate brain damage and neurological deficits.
The research stemmed from observations during the COVID-19 pandemic, where a noticeable rise in strokes was observed in individuals infected with SARS-CoV-2, mirroring trends seen with severe influenza A virus infections. To investigate, researchers utilized a preclinical animal model to examine the underlying mechanisms. Results demonstrated that viral infection influences blood clotting processes, increasing the likelihood of thrombus formation and subsequent vascular occlusion.
As a preventative measure, the researchers strongly recommend early influenza vaccination, especially for individuals considered vulnerable. Should infection occur, heightened awareness of neurological warning signs-such as numbness or paralysis-is advised. Prompt medical attention and intervention are crucial in cases potentially exhibiting stroke symptoms. Furthermore, the research suggests that medications such as acetylsalicylic acid (ASA) and antiviral therapies may prove beneficial in reducing progressive brain damage during treatment.
