More vitamin D may improve memory but too much may slow reaction time
Taking higher doses of vitamin D supplements can help improve memory and learning, but negatively impacts reaction time in postmenopausal women with a higher BMI. Researchers suggest the slowed reaction times may contribute to an increased risk of falls in older people.... Read More...
Alzheimer’s-like Symptoms Reversed in Mice, USC Researchers Say
A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop symptoms of the disease.... Read More...
Data Sharing Uncovers Five New Risk Genes For Alzheimer’s
A new study of the genetic data from over 94,000 people with Alzheimer's has identified five new risk genes, as well as confirmed 20 other known genes in the disease.... Read More...
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.... Read More...
Study Finds Ethnoracial Differences in Alzheimer’s
A new study reveals Hispanic Americans diagnosed with Alzheimer's disease tend to survive significantly longer with the condition than people from other ethnoracial groups. ... Read More...
How Exercise May Protect Against Alzheimer’s
Researchers report irisin, a hormone released during physical exercise, may promote neurogenesis in the hippocampus. The study sheds new light on why exercise helps improve memory and could help to protect the brain against Alzheimer's disease.... Read More...
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.... Read More...
Gum Disease Bacteria Implicated in Alzheimer’s Disease
Researchers have implicated Porphyromonas gingivalis, a bacteria commonly associated with gum disease, in Alzheimer's pathology. The study reports oral Pg infections leads to a colonization and increased production of amyloid beta.... Read More...
Stroke Drug May Also Prevent Alzheimer’s
Researchers report a new drug being developed to treat stroke patients may also have neuroprotective properties against Alzheimer's disease. ... Read More...
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.... Read More...
Decades Old Question About Alzheimer’s Protein Answered
A new study reports amyloid precursor proteins modulate neural signal transmission by binding to a specific receptor. Researchers say modulating the receptor could help treat Alzheimer's disease.... Read More...
