Our research group focuses on addressing highly relevant topics in the field of ischemic stroke with a particular focus on imaging. For example, we aim to identify imaging parameters on routine clinical MRI as well as CT that can not only help us predict long-term outcome post-stroke (i.e. response to thrombolysis, recurrent vascular events, and post-stroke dementia), but can also aid in accurately identifying stroke etiology and guide secondary prevention strategies. In collaboration with the Neuroradiology Department (Research Group Fiebach), we also explore the potential diagnostic and prognostic value of emerging, novel imaging techniques translated directly from pre-clinical findings. We recently launched a large-scale project that will pool the clinical and imaging data of several prospective ischemic stroke cohorts and will use a method called "lesion network mapping" to predict complex post-stroke symptoms including aphasia, acute disturbances of vigilance, as well as highly relevant long-term outcomes including post-stroke dementia and chronic depression.

The increased availability of magnetic resonance imaging (MRI) in the clinical routine has made it even more important for us to better understand and make use of the plethora of information each MR-image provides us. Our research group strives to identify imaging-parameters that not only help us clinicians make more personalized, patient-specific treatment decisions – but also help us understand the underlying pathophysiology of the stroke at hand and take us closer to understanding the intricacies of systemic human brain itself.
Most Important Projects
Cerebral small vessel disease
- Assessment of how selected cerebrovascular risk profiles (i.e. arterial hypertension, diabetes mellitus) affect distribution pattern of imaging biomarkers of cerebral small vessel disease
- Assessment of how imaging biomarkers of small vessel disease – in particular white matter lesions – can help predict long-term vascular risk and cognitive decline
Structural and functional connectivity
- Use of "lesion-network mapping" via the so-called human connectome to identify a potential network dysfunction associated with long-term post-stroke symptoms including dementia and chronic depression
- To identify structural and functional networks associated with early motor function recovery in acute phase post-stroke (<7 days) as potential targets for future intervention studies (i.e. rTMS)
- Identification of structural and functional networks associated with acute post-stroke symptoms (aphasia, sensory loss, dysphagia) to enhance our understanding of clinical neurology
