Research confirms link between sleep apnea and Alzheimer’s disease
New research has confirmed long-suspected links between sleep apnea and Alzheimer’s disease, finding identical signs of brain damage in both conditions. While the cause of Alzheimer’s disease remains a mystery, amyloid plaques that are toxic to brain cells are known indicators of the disease. The new research showed these plaques start in the same place […]

A Genetic Variant That Protects Against Alzheimer’s Promotes Immune Cell Functions
A new study conducted by researchers at the University of Eastern Finland found that the PLCG2-P522R genetic variant, which protects against Alzheimer’s disease, enhances several key functions of immune cells. The results obtained in the study highlight the importance of immune cells as a target of future development of new therapies for Alzheimer’s disease.

Stem cells can repair Parkinson’s-damaged circuits in mouse brains
The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson’s. Stem cells, which are endlessly adaptable, have offered the promise of better neural repair. But the brain’s precisely tuned complexity has stymied the development of clinical treatments.

160 genes linked to brain shrinkage
A new study implicates 160 genes in brain shrinkage seen on MRIs of 45,000 healthy adults. The shrinkage is in the cortex, the dimply outer layer of the brain that gives rise to thinking, awareness and action, and largely consists of gray matter.

Insomnia, sleeping less than six hours may increase risk of cognitive impairment
New research from Penn State College of Medicine may help health care professionals understand which patients who report insomnia are at increased risk for developing dementia. Middle-aged adults who report symptoms on insomnia and sleep less than six hours of asleep a night may be at increased risk of cognitive impairment.

Fructose Made in the Brain Could be a Mechanism Driving Alzheimer’s Disease
New research released from the University of Colorado Anschutz Medical Campus proposes that Alzheimer’s disease may be driven by the over activation of fructose made in the brain. The study was published in the Frontiers of Aging Neuroscience and outlined the hypothesis that Alzheimer’s disease is driven largely by Western culture that has resulted in […]

Metformin treatment linked to slowed cognitive decline
A six-year study of older Australians with type 2 diabetes has uncovered a link between metformin use, slower cognitive decline and lower dementia rates.

Middle-Aged Americans report more pain than the elderly
As people age, they tend to report more acute or chronic pain — a common sign of getting older. Yet, in the United States, middle-aged adults are now reporting more pain than the elderly, according to a paper published in the Proceedings of the National Academy of Sciences (PNAS).

PARKINSON’S DISEASE IS NOT ONE, BUT TWO DIFFERENT DISEASES
Disparate symptoms and varying disease rates in many Parkinson’s patients have puzzled researchers around the world. Now a comprehensive study from Aarhus University maps that there are actually two types of the disease, which should also be treated differently.

Beyond Plaques and Tangles: Genetic Variation May Increase Risk of Cognitive Decline
A genetic variation in some people may be associated with cognitive decline that can’t be explained by deposits of two key proteins associated with Alzheimer’s disease, amyloid ß and tau, according to a study published in the September 16, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. The genetic […]
