Carriers of the Alzheimer's associated APOE4 gene have more than double the risk of developing severe COVID-19, a new study reports. Additionally, more microscopic hemorrhages were found in the brains of APOE4 carriers who contracted coronavirus. Researchers report those with the APOE4 gene also are more susceptible to developing long-term symptoms following COVID infection, including an increased risk of mental fatigue.
In fruit fly models, an ABCA1 agonist can restore specific alterations of neuroprotective mechanisms associated with a genetic predisposition to Alzheimer's disease.
A new framework reveals Alzheimer's disease is far more complex than previously believed. Rather than being a disease where the same causes produce the same outcomes, researchers found three different models for the disease, each with its own characterizations and dynamics.
Dasatinib, an FDA-approved drug for chronic myeloid leukemia, and an experimental drug for liver cancer reduced neuroinflammation, tau phosphorylation, and amyloid secretion in cell cultures of post-mortem brain samples of those with the APOE4 Alzheimer's associated gene.
Inhibiting the NHE6 gene abolished the formation of amyloid-beta plaques in mouse models of Alzheimer's disease.
Too much or too little sleep were both linked to increased risk of cognitive decline, researchers report.
Bumetanide, an FDA-approved potent diuretic used to treat fluid retention caused by heart, kidney, and liver disease may lower the risk of developing Alzheimer's disease for those with a genetic predisposition.
Stem cell study reveals astrocytes carrying the Alzheimer's associated APOE4 gene release more cholesterol than those carrying the APOE3 gene. Findings shed light on how different versions of the APOE gene in astrocytes influence amyloid-beta production and how the oversupply of cholesterol associated with APOE4 astrocytes may promote amyloid-beta formation in Alzheimer's patients.
Subtle changes in fractal motor activity regulation in cognitively healthy women may be a sign of preclinical Alzheimer's disease, researchers report.
Depressed middle-aged carriers of the APOEe4 Alzheimer's genetic variant are at risk of developing tau accumulations in brain areas associated with emotion and memory.
Adults over 80 who maintained a healthy lifestyle, including exercise and diet, had a lower risk of cognitive decline, even if they had genetic risk factors for dementia.
Retinal scans can help researchers detect Alzheimer's disease and track its progression in those with the APOE4 genetic risk factor for the neurodegenerative disorder. The scans can detect blood vessel deterioration linked to the genetic biomarker.
