Alzheimer's alarm over anesthetics
10-25-2006 · EurekAlert!Giving elderly patients certain general anesthetics could increase their risk of developing Alzheimer's disease and other memory and attention problems. This is according to recent test tube and animal studies which are beginning to show that certain anesthetics reduce the rate at which brain cells are born and develop.

- Common anesthetic may induce cell death, generation of Alzheimer's-associated protein
02-06-2007 · EurekAlert!
A new study has found how one of the most commonly used anesthetics may produce Alzheimer's-like changes in the brain. Researchers from Massachusetts General Hospital and colleagues describe the mechanism by which the anesthetic isoflurane may induce both the cell-death process known as apoptosis and the generation of amyloid-beta protein in cultured neural cells.

- Role of anesthetics in Alzheimer's disease: Molecular details revealed
01-25-2007 · EurekAlert!
Inhaled anesthetics commonly used in surgery are more likely to cause the aggregation of Alzheimer percents disease-related plaques in the brain than intravenous anesthetics say University of Pittsburgh School of Medicine researchers in a journal article published in the Jan. 23 issue of Biochemistry. This is the first report using state-of-the-art nuclear magnetic resonance (NMR) spectroscopic technique to explain the detailed molecular mechanism behind the aggregation of amyloid β (Aβ) peptide due to various anesthetics.

03-09-2007 · EurekAlert!
Researchers at the University of Pennsylvania's School of Medicine have discovered that common inhaled anesthetics increase the number of amyloid plaques in the brains of animals, which might accelerate the onset of neurodegenerative diseases like Alzheimer's. Roderic Eckenhoff, MD, vice chair of Research in the University of Pennsylvania's Department of Anesthesia and Critical Care, and his co-authors, report their findings in the March 7 online edition of Neurobiology of Aging.

- Learning slows physical progression of Alzheimer's disease
01-23-2007 · EurekAlert!
Learning appears to slow the development of two brain lesions that are the hallmarks of Alzheimer's disease, scientists at UC Irvine have discovered. The finding suggests that the elderly, by keeping their minds active, can help delay the onset of this degenerative disease.
