TL;DR: The positive predictive value (PPV) for all-cause dementia, Alzheimer’s disease and vascular dementia for each dataset alone and in combination, and algorithmic code combinations to improve PPV are calculated and three algorithms that balanced a high PPV with reasonable case ascertainment are identified.
Journal ArticleDOI
Identifying dementia cases with routinely collected health data: A systematic review.

TL;DR: This work evaluated the accuracy of data sets used for dementia case identification inspective, population‐based studies through linkage to routinely collected, coded health‐care data sets.
Journal ArticleDOI

TL;DR: It is concluded that it is reasonable to use administrative data to identify people with epilepsy (PWE) in epidemiological research, and the use of AEDs alone to identify PWE is cautioned against.

TL;DR: The Dementias Platform UK Data Portal is a data repository facilitating access to data for 3 370 929 individuals in 42 cohorts and projects are varied including multi-modal, machine learning, and Mendelian randomisation analyses.
Journal ArticleDOI
The diagnosis, burden and prognosis of dementia: A record-linkage cohort study in England.
Mar Pujades-Rodriguez,Valentina Assi,Arturo Gonzalez-Izquierdo,Tim Wilkinson,Christian Schnier,Catherine Sudlow,Harry Hemingway,William Whiteley +7 more
TL;DR: Most people with a record of dementia in linked UK EHR had some corroborating evidence for diagnosis and the estimated 10-year risk of dementia was higher than published population-based estimations, suggesting EHR are a promising source of data for dementia research.
