Influenza, long COVID & co: What impact do infections have on our brain and how can we protect ourselves

In this episode of HZI InFact, Prof. Martin Korte, head of the
research group "Neuroinflammation and Neurodegeneration" at the
Helmholtz Centre for Infection Research (HZI), discusses the links
between infections, the immune system, and the brain. How do
viruses and bacteria affect our cognitive abilities? What role do
they play in neurodegenerative diseases like Alzheimer’s and
dementia? And how can we protect our brain in the long term?
Episode Topics: • Why some infections cause neurological long-term
effects • How viruses and bacteria can indirectly attack our brain
• The role of the blood-brain barrier in infections • Why the
immune system affects the brain longer than other organs • How
vaccinations can help prevent neurodegenerative processes • What
measures keep the brain fit and healthy Exclusive Insights: Prof.
Korte explains why the brain needs months to recover after an
infection, even if the illness is over, and why older individuals
are particularly at risk. He also shares practical tips on how
everyone can actively protect their brain from infections and aging
processes – from physical activity and healthy nutrition to
lifelong learning. Glossary: Blood-Brain Barrier: A protective
barrier between the bloodstream and the brain that shields the
nervous system from harmful substances – but is not completely
impenetrable. Microglial Cells: Specialized immune cells in the
brain responsible for its protection and regeneration, but also
involved in inflammatory responses. Sickness Behavior: A biological
phenomenon that causes fatigue, lack of motivation, and social
withdrawal during illness – an evolutionary defense mechanism of
the body. #Podcast #Science #Neurology #LongCovid
