Research focus
The current research of the Dementia Research team is based on the Czech Brain Aging Study (CBAS) – a unique, national, multicentric and longitudinal prospective cohort study. The aim of CBAS is to study the early functional, metabolic, structural and genetic biomarkers of Alzheimer´s Disease and other dementias in blood, CSF and magnetic resonance imaging with a focus on synucleinopathies, tauopathies and TDP­-43-pathies. These studies are complemented by animal studies with emphasis on translational aspect of the used methodology. CBAS also explores the effects of lifestyle factors on the brain’s maintenance using questionnaires and nonpharmacological interventions. CBAS team consists of two core synchronized sites – Cognitive Centers at ICRC St. Anne´s University Hospital Brno and at Motol University Hospital, Prague.

Research objectives

  • Evaluation of neuropsychological and spatial navigation tests as an early markers of neurodegeneration.
  • Defining structural, metabolic and functional biomarkers on MRI and PET in humans.
  • Exploring epidemiological risk factors in primary and secondary prevention of dementia.
