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.

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.

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.

Alzheimer’s disease is a ‘double-prion disorder’

Self-propagating amyloid and tau act as prions in the pathology of Alzheimer's disease. Higher levels of the prions in human brain samples were strongly correlated with early onset of Alzheimer's and death at a younger age.

Experimental PET scan detects abnormal tau protein in brains of living former NFL players

PET imaging of former NFL players who exhibited cognitive decline and psychiatric symptoms linked to CTE showed higher levels of tau in areas of the brain associated with the neurodegenerative disease.

Hip Fractures May Be An Early Sign of Alzheimer’s in Older People

Researchers report they have identified biomarkers of Alzheimer's disease in spinal fluid samples of a significant number of older patients hospitalized as a result of hip fractures. The study suggests neural alterations that lead to poor balance in older people may signify an increased risk of falls that result in hip fractures, and Alzheimer's disease. Researchers suggest the hip fracture, therefore, may serve as an early sign of Alzheimer's in older patients.

Sleep Deprivation Accelerates Alzheimer’s Brain Damage

A new study reports sleep deprivation increases the levels of tau, and accelerates the spread of the protein, in the brain. The findings reveal a lack of sleep alone may help drive the development of Alzheimer's disease.

Epigenetics Contributes to Male and Female Differences in Fear Memories

A new mouse study reveals males recall fearful memories better than females. Researchers attribute the difference to the gene Cdk5, which has previously been implicated in creating fear memories and stress behaviors. The study reports Cdk5 is naturally activated in males, but not females.

Blood-Brain Barrier Breakdown an Early Driver of Dementia

A new study reports leaky capillaries in the brain may be an early sign of Alzheimer's disease as it can signal cognitive impairment prior to the buildup of proteins associated with the neurodegenerative disease.
