The evidence synthesis group brings together researchers and academics to collaborate, share expertise and generate high quality systematic reviews and meta-analyses relating to dementia, its prevention or delay.

“We are keen to ensure that our work translates into clinical practice where possible”

So far we have published several highly cited reviews in key areas including smoking, cholesterol and alcohol.

Knowledge translation

We are keen to ensure that our work translates into clinical practice where possible and always raises new questions, highlights gaps in the evidence base and signposts the key directions for future research.

Our reviews have been cited by expert consensus documents and guidelines including the 2014 World Alzheimer report, World Health Organisation knowledge summaries, the literature used as a basis for the UK government endorsed Blackfriars consensus, public facing health messages and a BMJ best practice guide.

Evidence Synthesis and Collaboration
  • Impact on research
  • Knowledge translation
Over 20 systematic reviews published
  • Highly cited in the scientific literature
  • Cited in clinical guidelines and public and patient facing information sources
For example
  • Systematic reviews on smoking and dementia risk
  • Included in expert consensus by the World Health Organization

Our systematic reviews and meta-analyses relate to multiple risk factors for incident dementia, potential interventions and methodologies used for cognitive assessment.
