Beta Amyloid

Marker for Alzheimer’s disease may affect mental function even in healthy adults

High levels of the protein beta-amyloid in the brain that is associated with Alzheimer’s disease may affect brain performance even in healthy adults, according to a study published in the February 1, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“In our study, we observed that even in… Marker for Alzheimer’s disease may affect mental function even in healthy adults   



A new test might facilitate diagnosis and drug development for Alzheimer’s disease

An international team of researchers have developed a new method for measurement of aggregated beta-amyloid -  a protein complex believed to cause major nerve cell damage and dysfunction in Alzheimer’s disease. The new method might facilitate diagnosis and detection as well as development of drugs directed against aggregated beta-amyloid.

Alzheimer’s disease (AD) is the… A new test might facilitate diagnosis and drug development for Alzheimer’s disease   



Omega-3s may help lower risk of Alzheimer’s disease

Eating foods such as chicken, fish and nuts may help lower blood levels of a protein strongly associated with Alzheimer’s disease and memory problems, according to new research.

In the Columbia University study, people who consumed diets rich in omega-3 fatty acids had significantly lower levels of a protein called beta-amyloid in their blood… Omega-3s may help lower risk of Alzheimer’s disease   



Immune system may protect against Alzheimer’s changes

Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer’s-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

Researchers at the Peninsula College of Medicine and Dentistry, University of Exeter with colleagues in the National Institute on… Immune system may protect against Alzheimer’s changes   



Biomarkers in cerebrospinal fluid can identify patients with Alzheimer’s disease

Analysis of specific biomarkers in a cerebrospinal fluid sample can differentiate patients with Alzheimer’s disease from those with other types of dementia. The method, which is being studied by researchers at Sahlgrenska Academy, may eventually permit earlier detection of Alzheimer’s disease.

Due to the similarity of the symptoms, differentiating patients with Alzheimer’s from those… Biomarkers in cerebrospinal fluid can identify patients with Alzheimer’s disease   



Team Unravels Central Mystery of Alzheimer’s

Scientists at The Scripps Research Institute (TSRI) have shed light on one of the major toxic mechanisms of Alzheimer’s disease. The discoveries could lead to a much better understanding of the Alzheimer’s process and how to prevent it.

The findings, reported in the April 10, 2013 issue of the journal Neuron, show that brain… Team Unravels Central Mystery of Alzheimer’s   



Alzheimer’s disease: are we close to finding a cure?

First described in 1906 by Dr. Alois Alzheimer, Alzheimer’s disease is the most common form of dementia, accounting for around 60-80% of cases. It is characterized by problems with memory, thinking and behavior.

Onset is most common in individuals aged 65 and over, although people in their 40s and 50s can develop what… Alzheimer’s disease: are we close to finding a cure?   



Poor sleep linked to toxic buildup of Alzheimer’s protein, memory loss

Sleep may be a missing piece in the Alzheimer’s disease puzzle.

Scientists at the University of California, Berkeley, have found compelling evidence that poor sleep - particularly a deficit of the deep, restorative slumber needed to hit the save button on memories - is a channel through which the beta-amyloid protein believed to trigger… Poor sleep linked to toxic buildup of Alzheimer’s protein, memory loss
