The original title of our proposal to the Chesshire Lehmann Fund was “Understanding the causal pathways connecting dementia and Alzheimer’s Disease with risk of excess winter mortality.”

We believe that this report has covered a great deal of ground in furthering that understanding.  It has done so largely through triangulation – a research technique by which a variety of different approaches, evidence sources, and people are brought to bear on a single issue. This report is, in every sense, triangulated.

The single issue of concern is to identify at least some possible explanations for recently published data from the UK’s Office for National Statistics, relating to a high rate of excess winter deaths among people who were living with Alzheimer’s Disease or related dementias.

The evidence base brought to bear on the issue includes analysis of mortality statistics in England, Scotland, Wales and Northern Ireland, reviews of relevant scientific publications, as well as insights gained from informal interviews with carers, both familial and professional.
