Anesthetic neuropharmacology and physiology

Our group study neuroinflammation and longterm neurocognitive decline after surgery or trauma.

Surgery is closely associated with longterm neurocognitive impairment, a condition also known as postoperative cognitive dysfunction (POCD).

Our translational project explore mechanisms, pathophysiology, prevention and long-term outcome of surgery-induced neuroinflammation with postoperative neurocognitive disorders and dementia. Using comprehensive clinical and experimental platforms in animals and cells, combined with translational studies in surgical patients and nationwide outcome studies, our group identify and describe key mechanisms and at-risk patients for postoperative neurocognitive decline or dementia.

We investigate surgery-induced immune activation, neuronal function in cognitive processing and immune activation in relation to long term brain dysfunction and systemic inflammation in animal and cell models. We translate experimental findings to humans by application of state-of-the-art brain PET-imaging, cerebrospinal fluid neurochemistry, cognitive test batteries with advanced pattern recognition analysis of systemic immune system in surgical patients to explore the association between trauma-induced changes in brain and systemic immune systems and later neurocognitive decline.

Clinical results are combined with nationwide outcome studies on the impact of surgery or trauma on later cognitive performance and dementia aiming to identify at-risk patients to define novel therapeutic strategies.
