Introduction

Alzheimer’s Research UK is the UK’s leading dementia research charity, dedicated to finding preventions, treatments, and ultimately a cure for Alzheimer’s disease and other dementias^{1Alzheimer's Research UK Annual ReportOpen reference}. Founded in 1992 as the Alzheimer’s Research Trust, the organization has invested over £100 million in cutting-edge research across the UK and internationally. As the largest charitable funder of dementia research in the UK, the charity brings together scientists, clinicians, and people affected by dementia to accelerate progress^{2Alzheimer's disease2023 · Lancet · PMID 37241246Open reference}.

The organization funds research at universities and hospitals across the UK, focusing on understanding the diseases that cause dementia, developing new treatments, and improving diagnosis. Alzheimer’s Research UK also plays a crucial role in raising awareness and challenging stigma around dementia. The charity’s mission is to defeat dementia through world-class research, and its strategic vision encompasses all aspects of the research pipeline from basic science through to clinical translation.

The Global Challenge of Dementia

Epidemiological Context

Dementia represents one of the greatest global health challenges of the 21st century. According to recent estimates, over 55 million people worldwide are living with dementia, with nearly 10 million new cases diagnosed each year^{3Global prevalence of dementia2023 · Nat Rev Neurol · PMID 37231167Open reference}. In Europe alone, approximately 7 million people are affected, and the UK has one of the highest prevalence rates in the world with over 850,000 people living with dementia.

The economic impact is staggering, with dementia costing the UK economy over £34 billion annually—more than cancer, heart disease, and stroke combined. This includes direct healthcare costs, social care expenditure, and the enormous value of informal caregiving. Without effective treatments or prevention strategies, these costs are projected to rise dramatically as populations age.

The Science of Alzheimer’s Disease

Alzheimer’s disease is the most common cause of dementia, accounting for approximately 60-70% of all cases. The disease is characterized by two key pathological hallmarks^{4Amyloid and tau pathology in AD2023 · Nat Rev Neurosci · PMID 36859567Open reference}:

Amyloid plaques: Accumulation of amyloid-beta (Aβ) peptides in the brain, forming extracellular plaques that disrupt neuronal function. The amyloid hypothesis has dominated Alzheimer’s research for decades, though recent clinical trial results have complicated this narrative^{5The amyloid hypothesis of Alzheimer's disease2023 · Nat Rev Neurosci · PMID 36806789Open reference}.

Neurofibrillary tangles: Abnormal aggregation of tau protein inside neurons, leading to cell death. Tau pathology correlates more closely with cognitive decline than amyloid, making it an important therapeutic target.

Beyond these classical features, modern research has revealed the importance of^{6Inflammation in Alzheimer's disease2023 · Nat Rev Immunol · PMID 37165082Open reference}:

• Neuroinflammation and microglial activation

• Synaptic dysfunction and loss

• Vascular contributions to cognitive impairment

• Metabolic dysfunction in brain cells

• Proteostasis disruption and cellular stress

The NIA-AA research framework provides a biological definition of Alzheimer’s disease based on amyloid, tau, and neurodegeneration biomarkers, enabling more precise diagnosis and tracking of disease progression^{7NIA-AA research framework for Alzheimer's disease2023 · Alzheimers Dement · PMID 36996888Open reference}.

Research Programs

Research Priority Areas

Alzheimer’s Research UK funds research across multiple priority areas, reflecting the complexity of dementia and the need for multiple therapeutic approaches:

Cause and Risk Factors

Understanding why Alzheimer’s disease develops is fundamental to finding treatments. The charity funds research into^{8Genetics of Alzheimer's disease2023 · Curr Opin Genet Dev · PMID 37202345Open reference}:

Genetic Risk Factors: Genome-wide association studies have identified over 40 genetic loci associated with increased Alzheimer’s risk. The APOE gene remains the strongest genetic determinant, with the ε4 allele increasing risk approximately 3-4 fold^{9APOE and Alzheimer's disease2023 · Nat Rev Neurol · PMID 37225581Open reference}. Other important genes include TREM2, which plays a critical role in microglial function^{10TREM2 and Alzheimer's disease2023 · J Exp Med}, and variants in genes involved in immune function, lipid metabolism, and synaptic plasticity.

Molecular Mechanisms: Research into the fundamental biology of Alzheimer’s disease, including:

• Amyloid precursor protein (APP) processing and Aβ generation
