Blood-brain barrier (BBB) breakdown is observed in older versus younger adults and in late-onset Alzheimer’s disease versus age-matched controls, but its causes and consequences in aging are unclear. We tested the hypothesis that BBB breakdown is associated with cognitive decline and inflammation in nondemented elders. Read & Research Alzheimer’s More

The impact of prediabetes and diabetes on cognitive decline and the potential underlying mechanisms remain unclear. We investigated whether prediabetes and diabetes accelerate cognitive decline and brain aging, and the initial pathological changes linked to microvascular processes.

A minority of patients with sporadic early-onset Alzheimer’s disease (AD) exhibit de novo germ line mutations in the autosomal dominant genes such as APP, PSEN1, or PSEN2. We hypothesized that negatively screened patients may harbor somatic variants in these genes. Read & Research Alzheimer’s More

The new National Institute on Aging and the Alzheimer’s Association Research Framework for Alzheimer’s disease has been developed to accelerate drug discovery and offer a common structure and language to construct new Alzheimer’s disease conceptual models. However, as a “complex” disease, a model based on systems-level understanding is needed to Read & Research Alzheimer’s More

Several neurodegenerative brain proteinopathies, including Alzheimer’s disease (AD), are associated with cerebral deposition of insoluble aggregates of α-synuclein. Previous studies reported a trend toward increased cerebrospinal fluid (CSF) α-synuclein (α-syn) concentrations in AD compared with other neurodegenerative diseases and healthy controls.

Cerebrospinal fluid (CSF) protein analysis may facilitate detection and elucidate mechanisms of neurological consequences from repetitive head impacts (RHI), such as chronic traumatic encephalopathy. We examined CSF concentrations of total tau (t-tau), phosphorylated tau, and amyloid β1-42 and their association with RHI in former National Football League (NFL) players.

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
