Tauopathies are neurodegenerative diseases characterized by TAU protein–related pathology, including frontotemporal dementia and Alzheimer’s disease among others. Mutant TAU animal models are available, but none of them faithfully recapitulates human pathology and are not suitable for drug screening. To create a new in vitro tauopathy model, we generated a footprint-free triple Read & Research Alzheimer’s More

Molecular imaging techniques using 18F-fluorodeoxyglucose, amyloid tracers, and, more recently, tau ligands have taken dementia research by storm and undoubtedly improved our understanding of neurodegenerative diseases. The ability to image in vivo the pathological substrates of degenerative diseases and visualize their downstream impact has led to improved models of pathogenesis, better Read & Research Alzheimer’s More

Alzheimer’s disease (AD) symptoms reflect synaptic dysfunction and neuron death. Amyloid-β oligomers (AβOs) induce excess calcium entry into neurons via N-methyl-D-aspartate receptors (NMDARs), contributing to synaptic dysfunction. The study described here tested the hypothesis that AβO-stimulated calcium entry also drives neuronal cell cycle reentry (CCR), a prelude to neuron death Read & Research Alzheimer’s More

Consent is generally required for research and sharing rich individual-level data but presents additional ethical and legal challenges where participants have diminished decision-making capacity. We formed a multi-disciplinary team to develop best practices for consent in data-intensive dementia research. We recommend that consent processes for research and data sharing support Read & Research Alzheimer’s More

Although Congress has allocated substantial funding to accelerate dementia research, nearly all attempts to find effective preventions and treatments for dementia have failed. Current dementia therapies offer little hope. They provide only modest clinical benefits and have limited impact on the unrelenting progression of disease.

The body needs vitamin B-12 for many processes. People with a deficiency may have neurological symptoms and fatigue, while an excess may indicate liver disease or diabetes. Doctors can use a vitamin B-12 level test to determine how much B-12 is in the body. Find out more about the test Read & Research Alzheimer’s More

Early-onset Alzheimer’s disease is a form of dementia that begins before the age of 65. Recognizing the initial symptoms can help a person seek treatment earlier and slow the progression of the disease. In this article, learn about ten signs of early-onset Alzheimer’s. We also cover how to help a Read & Research Alzheimer’s More

Agitation is one of the most challenging neuropsychiatric symptoms to treat in Alzheimer’s disease and has significant implications for patient and caregiver. A major source of difficulty in identifying safe and effective treatments for agitation is the lack of validated biomarkers.

Cognitive function is an important end point of treatments in dementia clinical trials.
