Key Points: Hearing loss is strongly associated with cognitive decline and dementia in older adults, hinting that a general collapse of brain function accompanies deficits in its sensory architecture. Our hearing ability depends on sensory cells within our inner ear that change in length in response to sound, which surprisingly could be affected by cholesterol… Continue reading New Study Shows Plant-Derived Phytosterols Prevent Aging-Associated Hearing Loss

NAD⁺ Precursor Nicotinamide Enhances Nerve Insulation for Rapid Electrical Signal Propagation: Greek Study
Key Points Myelin is a layer of fat that wraps around axons — protrusions from neurons that propagate electrical signals in the nervous system, including within the brain. Evidence has shown that myelin loss — demyelination — occurs as we grow older and that it contributes to the pathology of age-related neurological conditions like Alzheimer’s… Continue reading NAD⁺ Precursor Nicotinamide Enhances Nerve Insulation for Rapid Electrical Signal Propagation: Greek Study
Intermittent Fasting Improves Memory and Rescues Brain Pathology in Alzheimer’s: UC San Diego Study
Key Points: A new study helps to confirm that intermittent fasting isn’t just a fad diet. Researchers from the University of California (UC) San Diego report in Cell Metabolism that TRF prevents memory loss and reduces amyloid plaques in AD mice. Whittaker and colleagues also show that TRF elevates blood ketones — the brain’s fat-derived… Continue reading Intermittent Fasting Improves Memory and Rescues Brain Pathology in Alzheimer’s: UC San Diego Study
Latest Study Shows Senolytic Therapy Protects the Brain from Injury and Preserves Memory
Key Points: Chronic brain inflammation is a primary affliction of TBI that scientists surmise inflicts neurodegeneration. Such inflammation may be caused by senescent cells, which contribute to driving the aging process. Now, researchers from Augusta University in Georgia show that senolytics — compounds that selectively destroy senescent cells — could benefit TBI patients by mitigating… Continue reading Latest Study Shows Senolytic Therapy Protects the Brain from Injury and Preserves Memory
UCI Study Shows Simple Fragrance Boosts Memory to Counter Brain Aging
Key Points: With age, our sense of smell begins to deteriorate, especially after the age of 70. Such olfactory deficits are associated with neurodegeneration, cognitive impairment, dementia, and all-cause mortality. This means our ability to smell is closely tied to brain aging and longevity. Now, scientists from the University of California Irvine (UCI) may have… Continue reading UCI Study Shows Simple Fragrance Boosts Memory to Counter Brain Aging
Stanford Researchers Reactivate Brain Stem Cells in Old Mice
Key Points: Scientists have discovered a way to reawaken dormant brain stem cells in older animals, which improves neuron production in their aging brains. Researchers from Stanford University discovered that as brain stem cells age, they lose their ability to migrate. This ability is crucial for the process of neurogenesis, which is the generation of… Continue reading Stanford Researchers Reactivate Brain Stem Cells in Old Mice
Breakthrough Alzheimer’s Treatment Achieves Historic FDA Stamp of Approval
Highlights: In the realm of neurodegenerative disorders, Alzheimer’s is arguably one of the most devastating diseases, afflicting more than 6.5 million people in the U.S. alone. And although no real cure exists, the available research suggests that compounds capable of extinguishing amyloid beta plaques are promising therapeutics to mitigate this deadly disease. Accordingly, preliminary clinical… Continue reading Breakthrough Alzheimer’s Treatment Achieves Historic FDA Stamp of Approval
Israeli Scientists Find Potential Breakthrough Drug for Alzheimer’s
Key Points: Someone develops Alzheimer’s disease (AD) every 66 seconds in the United States. However, we still don’t know what triggers this neurodegenerative disease. Now, researchers from the Ben-Gurion University of the Negev in Israel have clued in on a protein called VDAC1. VDAC1 is embedded within the walls of mitochondria and transports a multitude… Continue reading Israeli Scientists Find Potential Breakthrough Drug for Alzheimer’s
New Study Reveals Running Can Protect Against Brain Aging
Key Points: Running preserves the wiring of neurons involved in memory during aging in mice, according to new research. Long-term running significantly increases the input from newly formed neurons onto “old” adult-born neurons, preventing the loss of adult-born neurons in regions of the brain crucial for contextual and spatial memory. Researchers from Florida Atlantic University,… Continue reading New Study Reveals Running Can Protect Against Brain Aging
Consuming 500 mg of Cocoa a Day Recovers Memory Deficits: Large Columbia University Study
Key Points: Flavanols are food constituents in certain fruits and vegetables, including tea, apples, berries, grapes, and cocoa. Smaller studies have shown that consuming flavanols, which have an effect on new blood vessel formation, improves memory. Now, researchers from Columbia University have replicated similar results in a much larger study. As reported in PNAS, Brickman… Continue reading Consuming 500 mg of Cocoa a Day Recovers Memory Deficits: Large Columbia University Study
