Title: Prevalence of all cause young onset dementia and time lived with dementia: analysis of primary care health records Summary – 2022 study designed to calculate the prevalence of young onset dementia using primary care electronic health records in England and to determine the length of time lived with dementia in relation to current age. The estimated prevalence figure for young onset in this analysis provides a truer estimate of people living with young onset dementia in England because it includes all people with this diagnosis irrespective of their current age Click here
Title: An integrative literature review on the nomenclature and definition of dementia at a young age Summary – 2021 literature review to explore operational definitions and define dementia at a young age. Despite relative consensus on the term young-onset dementia and an age at symptom onset being used as a cut-off criterion, much is still unclear concerning possible etiologies of dementia at a young age. In this study, controversies were detected for discussion in an international consensus study. Click here
Title: Provisional consensus on the nomenclature and operational definition of dementia at a young age, a Delphi study Summary – 2021 study was part of the Prevalence Recognition and Care pathways in young Onset Dementia (PRECODE) project on the prevalence, incidence, definition, and care pathways of dementia at a young age. The Delphi study was designed to reach agreement on which definitions are most appropriate for this group of people. Click here
Title: Global prevalence of young onset dementia. A systematic review and meta-analysis Summary – 2021 study designed to determine the global prevalence of young onset dementia. This systematic review and meta-analysis found an age-standardized prevalence of YOD of 119.0 per 100 000 population, although estimates of the prevalence in low-income countries and younger age ranges remain scarce. These results should help policy makers organise sufficient health care for this subgroup of individuals with dementia. Clickhere
Title: Post-current UK clinical practice in diagnosing dementia in younger adults: compliance with quality indicators in electronic health records from mental health trusts Summary – 2021 study designed to examine current UK practice in diagnosis of patients under 65 with young onset dementia, within 5 years of date of diagnosis, identified from electronic health records of 8 NHS mental health trusts. Findings confirmed variation in clinical practice and identified commonly missed items in examination and enquiry compared to expert consensus. Click here
Title: Post-diagnosis young-onset dementia care in the National Disability Insurance Scheme Summary – 2021 paper outlines the Australian experience of recognising the diagnosis of young onset dementia as a disability. The objective of this study was to examine experiences and satisfaction with disability services so far among people with young-onset dementia and their care partners and identify strategies for service and system improvement.

Title:New insights into atypical Alzheimer’s disease in the era of biomarkers Summary – 2021 review paper outlines how availability of cerebrospinal fluid (CSF) and radiological biomarkers of Alzheimer’s disease pathologies and incorporation of atypical forms of Alzheimer’s disease eg visual, language and behavioural variants) into new diagnostic criteria increasingly allows them to be more confidently diagnosed early in their illness. Increasing use of Alzheimer’s disease biomarkers in clinical practice and greater recognition of diverse subtypes can ensure early diagnosis, timely treatment, and appropriate support. Click here
Title: Imaging biomarkers in neurodegeneration: current and future practices Summary – 2020 review focusses on neuroimaging, specifically positron emission tomography (PET) and magnetic resonance imaging (MRI), giving an overview of the current established practices clinically and in research as well as new techniques being developed. We will also discuss the use of machine learning (ML) techniques within these fields to provide additional insights to early diagnosis and multimodal analysis. Particular types of biomarkers will be more valuable in diagnosing young onset dementia than in later onset dementia where the brain related changes caused by ageing limit their use. Click here
