Sleep Problems Could Affect Your Memory
2012-02-15 04:59:40

The amount and quality of sleep you get at night may affect your memory later in life, according to research that was released this week and will be presented at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012. "Disrupted sleep appears to be associated with the build-up of amyloid plaques, a hallmark marker of Alzheimer's disease, in the brains of people without memory problems," said study author Yo-El Ju, MD, with Washington University...

New potential therapy that restores motor function being planned for clinical trial Medical researchers at the University of Alberta have discovered a promising new therapy for Huntington disease that restores lost motor skills and may delay or stop the progression of the disease based on lab model tests, says the lead researcher. Because the new therapy uses a molecule already being used in clinical trials for other diseases, it could be used in a clinical trial for Huntington disease...

Overeating Can Contribute To Memory Loss
2012-02-13 08:51:18

New research suggests that overeating may double the risk of memory loss, or mild cognitive impairment (MCI), in people age 70 and older. US scientists have shown that a high caloric intake can substantially increase the risk of developing MCI, which is the stage between normal memory loss that comes with aging and early Alzheimer´s disease. The findings were released today at aan.com and will be presented at the American Academy of Neurology´s 64th Annual Meeting in New...

Alzheimer’s Breakthrough: Drug Appeared To Reverse Symptoms In Mouse Trial
2012-02-10 10:23:41

Scientists, long searching for a cure for Alzheimer´s, a reporting a dramatic breakthrough: a drug that quickly reverses the pathological, cognitive and memory deficits in mice afflicted with the disease. The results point to the significant potential that the drug, bexarotene, could help the more than 5 million Americans suffering from the brain disease. However, they cautioned that the study was only used in mice, and that the research needs much more work to determine if the...

Researchers tease out toxic role of tau oligomers One of the most distinctive signs of the development of Alzheimer's disease is a change in the behavior of a protein that neuroscientists call tau. In normal brains, tau is present in individual units essential to neuron health. In the cells of Alzheimer's brains, by contrast, tau proteins aggregate into twisted structures known as "neurofibrillary tangles." These tangles are considered a hallmark of the disease, but their precise role in...

Findings open new opportunities for studying Alzheimer´s and testing potential therapies For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study by Columbia University Medical Center (CUMC) researchers strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
