Cerebrovascular diseases

The group has broad interest in atherosclerosis, inflammation and acute stroke, including multi-modal imaging methods such as MRI, PET and ultrasound.

We have several active projects, both on primary and secondary prevention, as well as pre-hospital and in-hospital treatment of acute stroke.

Our research aims to reduce incidences of stroke (biomarkers), reduce stroke severity (neuroprotection) and improve patient outcome (cognition and vascular dementia), and includes both clinical and translational studies.

Main research areas

  • Acute stroke, inflammation and the gut-brain axis. The main aim of this group is to study the role of inflammation in acute stroke, and the impact of gut microbiota on cerebrovascular disease. Subgroup leader is Karolina Skagen.
  • Pre-hospital and acute stroke. The focus of this group is to improve and implement prehospital diagnostics and treatment of acute stroke patients. Subgroup leader is Else Charlotte Sandset.
  • Acute stroke treatment and atrial fibrillation. The scientific research interest is acute stroke treatment, diagnostic workup in acute ischemic stroke and the relation between stroke and atrial fibrillation. Subgroup leader is Anne-Hege Aamodt.
  • Stroke and cognition. This group aims to quantify and measure levels of cognitive impairment after stroke and to identify biological and clinical markers associated with prognosis for cognitive disorders following incident stroke. Subgroup leader is Hege Ihle-Hansen.
