Risk and progression of Alzheimer’s disease differ by gender
The risk of developing Alzheimer's disease is increased, and progression more rapid in women due to larger brain-wide accumulation and acceleration in the spread of tau. ... Read More...
Tau
Sorting protein in neurons defends against neurodegenerative disease
VPS35 is a novel critical component of tau metabolism and the pathology of neurodegenerative diseases. ... Read More...
Indications why older people are more susceptible to Alzheimer’s disease
Using a gene vector, researchers channeled the blueprint of the human tau protein into different aged mice. After a period of twelve weeks, the tau protein spread twice as fast in older mice than the younger cohort. Findings shed light on why Alzheimer's is predominantly an age-related neurodegenerative disease.... Read More...
Disrupted sleep in one’s 50s, 60s raises risk of Alzheimer’s disease
Sleep disruptions during middle age may be a potential biomarker for developing Alzheimer's disease later in life. Researchers found those who experienced sleep problems in their 40s and 50s had more amyloid beta accumulation in their brains later in life. Those whose sleep problems started in their 50s and 60s had increased levels of tau. Additionally, higher levels of tau were discovered in the brains of those who lacked synchronized brain waves associated with a good night's sleep.... Read More...
Alzheimer’s missing link ID’d, answering what tips brain’s decline
Study in mice and humans reveals reinforcing the activity of microglia could slow, or potentially halt, the proliferation of Tau tangles in Alzheimer's disease.... Read More...
Alzheimer’s disease: Sex affects tau accumulation in the brain
Women with the ApoE e4 genetic risk factor for Alzheimer's are more susceptible to tau accumulation in the brain than men.... Read More...
Sleep history predicts late-life Alzheimer’s pathology
Your sleep history during middle age may predict Alzheimer's pathology later in life. A decrease in sleep quality between 50 and 70 years of age is associated with higher levels of tau and amyloid beta in the brain. Changes in brain activity and quality of sleep could be a biomarker for Alzheimer's disease.... Read More...
Antioxidant puts up fight, but loses battle against protein linked to Alzheimer’s disease
During early Alzheimer's disease, SOD1 initially weakens levels of Tau protein. However, as the disease progresses, the antioxidant becomes less effective at protecting the brain against neurodegeneration.... Read More...
Memory Preserver: Researchers Develop Vaccine That Could Protect Against Alzheimer’s
Researchers have engineered a vaccine using virus-like particles that target Tau tangles in mouse models of Alzheimer's disease. Following the administration of the vaccine, the mice developed antibodies that cleared tau proteins, with the response lasting for a month. The mice also showed improvements in memory based tests and had less brain shrinkage than their peers who did not receive the vaccine. This suggests the vaccine prevented apoptosis. Researchers hope to move the vaccine to human clinical trials in the future.... Read More...
Brain changes linked with Alzheimer’s up to 30 years before symptoms appear
Researchers have identified average levels of biological and anatomical brain changes associated with Alzheimer's disease over thirty years before symptoms appear. In those with genetic risk factors for Alzheimer's, researchers found changes in cognitive performance up to 15 years before becoming symptomatic. Changes in Tau levels in the cerebral spinal fluid appeared up to 34 years before dementia symptoms occurred, and physical changes to the medial temporal lobe were apparent up to 9 years before cognitive impairment was apparent....

Why visual stimulation may work in fight against Alzheimer’s: Mouse study
Inducing gamma oscillations with visual stimulation via a process known as gamma entrainment using sensory stimuli, or GENUS, was shown to reduce amyloid plaques and phosphorylated tau in mouse models of dementia. Providing GENUS daily during the early stages of neurodegeneration helps preserve neural and synaptic density across multiple brain areas and improves cognitive performance for learning and spatial memory tasks....

New early detection blood test for Alzheimer’s
A new two-tier diagnostic blood test which evaluates both amyloid beta and tau, can help detect Alzheimer's disease in presymptomatic patients. ... Read More...
