We undertake innovative research into the causes of dementia, helping to develop and test new biomarkers and treatments.  


    The Dementia Research Group studies the underlying causes of dementia and undertakes translational research for the ultimate benefit of people living with dementia. We are a group of scientists and clinicians who collaborate closely with experts in related fields within the University of Southampton and beyond. 

    Our main research areas include:

    • Inflammation in dementia
    • Clinical studies and biomarkers in dementia
    • Neuroimaging  

    Memory Assessment and Research Centre  

    Our group works closely with the Memory Assessment and Research Centre (MARC), an internationally renowned research centre for dementia research and treatment for over 30 years. MARC has conducted over 200 pharmaceutical trials, observational studies or basic science projects aimed at improving the diagnosis and treatment of memory disorders including Alzheimer's disease; Lewy body dementia, Vascular dementia and Mild cognitive impairment. 

    MARC was instrumental in the development of our current treatments for Alzheimer's disease and is at the cutting edge of new therapies. MARC believes everyone can contribute to dementia research by taking part in simple surveys or by taking part in complex drug studies. MARC also educates the lay public and healthcare professionals about dementia and its treatment, and gives academic support to trainees and students to develop the next generation of researchers.
