Academic Interests

I am particularly interested in neuroscience and brain research with a focus on clinical application, and how illness or brain injury affects cognitive functions, thoughts and emotions in humans.

At the Department of Age Psychiatry my current focus is in the age-related mental illnesses, and how we can distinguish between aging and neurological and psychiatric disorders, as in dementia, depression, anxiety and cognitive impairment focusing on neuropsychological testing and imaging using functional Magnetic Resonance Imaging (fMRI).

fMRI is exciting and great progress has been made in recent years. It is now possible to understand how cognitive processes interact, and thus also relate differences in brain activation to cognitive processes. Completely clear connections are usually not found, but by putting together several pieces of the puzzle fMRI has the potential of becoming an integral part of the diagnostics Methods.
