Westman neuroimaging group
Our research is focused on the most common forms of dementia including Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), vascular dementia (VaD), frontotemporal lobar degeneration (FTD) and dementia in Parkinson’s disease (PDD).
Structural and functional neuroimaging play an important role in understanding the underlying mechanisms of different dementia disorders, potentially contributing to their management and diagnosis. We have a strong focus in different magnetic resonance imaging (MRI) techniques, such as structural MRI, magnetic resonance spectroscopy (MRS), functional MRI, diffusion tensor imaging (DTI), arterial spin labeling (ASL) and susceptibility weighted imaging (SWI). In addition to MRI, we work with other imaging modalities, such as positron emission tomography (PET) and computed tomography (CT).
We work with advanced tools to analysis neuroimaging data such as multivariate methods, machine learning and graph theory. Currently, a large part of the research within the group is focused on unraveling the heterogeneity in AD and to understand the substantial overlap between the different disorders. We believe it is important to work with the latest neuroimaging techniques to obtain a better understanding of the underlying mechanisms of the different diseases, to improve early diagnosis and differential diagnosis.

ProfessorCollaborations
We have several collaborations within our own department (NVS), with other departments at KI and with other universities in Sweden (Uppsala, Lund, Gothenburg and KTH). We also have strong collaborations with several foreign universities such as the University of Eastern Finland, University of Perugia, University of Stavanger, LaLaguna in Spain, the Mayo Clinic in Rochester and King's College London.
