National Geographic News (January 6, 2010): Cell Phone Use May Fight Alzheimer's, Mouse Study Says

Microwave radiation from cell phones may protect against and even reverse Alzheimer's-like symptoms, according to a new study involving genetically-tweaked mice.

The results were so surprising that study co-author Juan Sanchez-Ramos didn't believe them at first.

"It's such a dramatic and counterintuitive effect," said Sanchez-Ramos, a Unverisity of Florida neuroscientist.

"I joked that the animals must have been mislabeled or that the power wasn't switched on."

USA Today (December 30, 2009): Ginkgo Biloba has No Effect on Alzheimer's, dementia

The popular botanical ginkgo biloba does not improve memory nor does it prevent cognitive decline in older people, according to the largest and longest scientific study ever undertaken to look at the supplement.

An extract derived from the gingko tree, gingkgo biloba has been touted since the 1970s by the supplement industry and others as an aid to improving memory, cognitive decline, dementia and Alzheimer's disease. Ginkgo extract has been used in traditional Chinese medicine for more than 500 years, according to the American Botanical Council.

Science Daily (December 28, 2009): How Amyloid Beta Reduces Plasticity Related to Synaptic Signaling

The early stages of Alzheimer's disease are thought to occur at the synapse, since synapse loss is associated with memory dysfunction. Evidence suggests that amyloid beta (Aß) plays an important role in early synaptic failure, but little has been understood about Aß's effect on the plasticity of dendritic spines.

ABC News (December 23, 2009): Alzheimer's May Guard Against Cancer and Vice Versa

People with Alzheimer's disease may be less apt to get cancer and people with cancer may be less apt to get Alzheimer's disease, new research hints.

"Discovering the links between these two conditions may help us better understand both diseases and open up avenues for possible treatments," Dr. Catherine M. Roe of Washington University School of Medicine in St. Louis, noted in a written statement from the American Academy of Neurology.

Science Daily (December 18, 2009): Alzheimer's Detection: What's His Name Again? How Celebrity Monikers Can Help Us Remember

Famous mugs do more than prompt us into buying magazines, according to new Universite de Montreal research. In the December issue of the Canadian Journal on Aging, a team of scientists explain how the ability to name famous faces or access biographical knowledge about celebrities holds clues that could help in early Alzheimer's detection.

Science Daily (December 16, 2009); Researchers Find High Leptin Levels May Protect Against Alzheimer's Disease and Dementia

Publication Date: 
Wed, 12/16/2009

Researchers from Boston University School of  Medicine (BUSM) have found that higher leptin (a protein that controls weight and appetite) levels were associated with a lower incidence of Alzheimer's Disease (AD) and dementia. The study, which appears in the December 16th issue of the Journal of the American Medical Association, may open pathways for possible preventive and therapeutic interventions.

ABC News (December 14, 2009): Alzheimer's Protein May Be Early Risk Factor

Publication Date: 
Mon, 12/14/2009

Imaging tests may be able to detect the early signs of Alzheimer's disease long before it begins to affect memory, a finding that may lead to earlier, more effective treatments, US researchers said on Monday.

They said healthy people who have an abnormal buildup of a protein in the brain linked with Alzheimer's disease have a higher risk of developing the disease.

Time (December 8, 2009): Top 10 Medical Breakthroughs - No. 9: New Alzheimer's Genes

When it comes to understanding a disease as complex as Alzheimer's, the more the better - genes, that is. In September, 15 years since the last discovery of its kind, scientists finally identified a new set of genes that may contribute to the memory-robbing disorder. Two groups of researchers, working separately, homed in on three genes linked to the late-onset form of the disease, the type that hits people in their 60s or later and accounts for 90% of Alzheimer's cases in the US.

EurekAlert (December 10, 2009): Delaying the Aging Process Protects Against Alzheimer's Disease

Aging is the single greatest risk factor for Alzheimer's disease. In their latest study, researchers at the Salk Institute for Biological Studies found that simply slowing the aging process in mice prone to develop Alzheimer's disease prevented their brains from turning into a neuronal wasteland.

Science Daily (December 3, 2009): Strategies to Protect New Brain Cells Against Alzheimer's Disease

Stimulating the growth of new neurons to replace those lost in Alzheimer's Disease (AD) is an intriguing therapeutic possibility. But will the factors that cause AD allow the new neurons to thrive and function normally? Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that two main causes of AD amyloid-beta (aβ) peptides and apolipoprotein E4 (apoE4) impair the growth of new neurons born in adult brains.
