New research from the University of Duisburg-Essen is highlighting a significant link between influenza infection and an increased risk of stroke. Scientists at the Faculty of Medicine and University Hospital Essen have published findings indicating that acute influenza, in particular, can exacerbate brain damage and neurological deficits.
The study was initiated by observations noting a higher incidence of stroke cases during the COVID-19 pandemic amongst individuals infected with SARS-CoV-2, a trend reminiscent of those seen with severe influenza A virus infections. Researchers investigated the underlying mechanisms and discovered that viral infection appears to impact blood coagulation, increasing the likelihood of clot formation and potentially leading to vascular blockages.
The team emphasizes the importance of preventative measures, especially for vulnerable patient populations. Early influenza vaccination is strongly recommended. Should infection occur, individuals are urged to be vigilant for neurological warning signs, such as numbness and paralysis and to seek immediate medical attention if symptoms suggestive of a stroke develop. Furthermore, the researchers suggest that pharmaceuticals like acetylsalicylic acid (ASA) and antiviral therapies may play a role in mitigating progressive brain damage in the treatment of influenza-related complications.
