Alzheimer

Alzheimer`s enzyme identified

COLUMBIA, MO, United States (UPI) -- U.S. scientists have identified an enzyme responsible for the deterioration of brain function experienced by people suffering from Alzheimer`s disease.

Researchers at the University of Missouri-Columbia focused on amyloid-beta peptide, a common neuron killing toxin found in the brains of Alzheimer`s patients and astrocytes, which supports neurons and is the major cell in the brain.

Mediterranean diet helps against Alzheimer's

Tue Oct 10, 2006

CHICAGO (Reuters) - A so-called Mediterranean diet centered on fruits, vegetables, olive oil and a paucity of red meat and dairy products may lower the risk of Alzheimer's disease, for reasons that are unclear, researchers said on Monday.

The finding from Columbia University Medical Center in New York was based on a look at 1,984 adults with an average age of about 76, of whom 194 already had the debilitating brain disease and 1,790 did not. What they ate during the preceding 12 months was analyzed for how well it matched the Mediterranean diet.

Nerve stimulation promising for Alzheimer's

By Will Boggs, MD

NEW YORK (Reuters Health) - Electrical stimulation of the vagus nerve, which originates in the brain and then branches widely throughout the neck, chest and abdomen, seems to help some people with Alzheimer's disease, according to a new study.

"The study primarily showed that VNS (vagus nerve stimulation) is well tolerated and safe in patients with Alzheimer's disease for up to 12 months," Dr. Magnus J. C. Sjögren from the Karolinska Institute in Sweden told Reuters Health.

Insulin receptor stops progression of Alzheimer's disease

Monday, September 25, 2006

Providence, RI – Stimulation of a receptor in the brain that controls insulin responses has been shown to halt or diminish the neurodegeneration of Alzheimer's disease, providing evidence that the disease can be treated in its early stages, according to a study by researchers at Rhode Island Hospital and Brown Medical School.

Juice Is Powerful Weapon Against Alzheimer’s - Study

Drinking fruit or vegetable juice several times a week could help stave off Alzheimer's disease. This is according to a 9 year study involving nearly 2,000 people.

Participants reported on their consumption of fruit and vegetable juice starting in 1992. Their mental function was tested every 2 years thereafter. The results showed that:

Drinking juiced fruit and veg 'cuts Alzheimer's risk by 76%'

By EMILY COOK

 1st September 2006

Drinking fruit and vegetable juices more than three times a week can dramatically cut the chances of developing Alzheimer's disease, a new study has found.

Researchers followed almost 2,000 volunteers for up to 10 years while monitoring their juice consumption and brain function.

They found the risk of Alzheimer's was 76 per cent lower for those who drank juices more than three times a week compared to those who drank them less than once a week.

Alzheimer mice memories restored

Friday, 25 August 2006

US scientists increased the activity of an enzyme called Uch-L1 which is involved in memory function.

They then tested the mice and found that they had regained the ability to form new memories.

Writing in the journal Cell, the team said the work was in its early stages, but could help the development of therapies for the debilitating disease.

The scientists used transgenic mice that had Alzheimer's disease.

Aging adds to toxicity of Alzheimer's

Last Updated Thu, 10 Aug 2006 16:12:20 EDT CBC News

Alzheimer's is a disease of aging because part of the brain's cleanup crew that clears away the toxic buildup becomes less efficient, scientists have found.

Alzheimer's disease is the most common form of dementia. About 290,000 Canadians over 65 have the disease, approximately one in 20 in that age group. The number rises to one in four in those over 85. It slowly robs people of their memories and leads to behavioural changes.

Antibodies offer hope for Alzheimer's patients

Treatment with antibodies naturally produced in the body appears to halt the memory-robbing progression of Alzheimer's disease, according to promising early research that scientists plan to expand over the next year.

Scientists from Weill Cornell Medical School in New York reported the findings Tuesday at the 10th International Conference on Alzheimer's Disease and Related Disorders in Madrid. The findings are similar to those from an earlier German study of five patients over six months.
