Alzheimer’s a greater risk for women

March 19th, 2008 by Richard Brassaw

As baby-boomers age their risks of developing dementia, Alzheimer’s disease, or heart disease increases. Stroke and dementia are the most widely feared age-related neurological diseases, and are also the only neurological disorders listed in the 10 leading causes of disease burden. Researchers from Boston University School of Medicine (BUSM) followed 2,794 participants of the Framingham [...]

Possible Alzheimer’s treatment

March 18th, 2008 by Richard Brassaw

Alzheimer’s disease creates an accumulation of amyloid plaque deposits, which is composed primarily of the neurotoxic beta-amyloid peptide. The amyloid peptides are “cut” out from a larger protein called amyloid precursor protein (APP), then bind together to form plaques in the memory area of the brain. Vivian Y.H. Hook, PhD, professor, Skaggs School of Pharmacy [...]

Alzheimer’s detected with infrared light

March 17th, 2008 by Richard Brassaw

Alzheimer’s disease claims tens of thousands of American lives each year. A positive diagnosis, of the disease, is a process of eliminating all other possible causes with an incorrect diagnosis estimated to occur 10% of the time. It is only after someone dies can a pathologists examine slices of the brain under a microscope to positively identify [...]

Alzheimer’s brains found to have high levels of iron

March 16th, 2008 by Richard Brassaw

A recent study found that Alzheimer’s patients have an elevated level of magnetic iron oxides in the area of the brain that is affected by the disease. Jon Dobson, professor, Keele University, Staffordshire, UK, looked at the brain tissue from 11 Alzheimer’s disease patients and 11 age-matched control subjects. For the first time it shows [...]

Is Alzheimer’s caused by normal brain process–stuck in reverse?

March 15th, 2008 by Richard Brassaw

Researchers suspect that Alzheimer’s disease (AD) might be caused by the same mechanism that helps a healthy mind from being mired by minutia–like remembering what you ate for lunch for the past 8 Tuesdays–but for Alzheimer’s patients the mechanism has gone into overdrive and with it stuck in reverse. In a normal brain there is a [...]

Alzheimer’s more likely when both parents have the disease

March 12th, 2008 by Richard Brassaw

The leading cause of cognitive impairment in the U.S. elderly is Alzheimer’s disease. Because it is so common it is not unusual for both parents to develop the disease and presumably their offspring would be more likely to carry any genes associated with Alzheimer’s disease. Suman Jayadev, MD, University of Washington, Seattle, and co-researchers, studied 111 [...]

Alzheimer’s detection improved along with other forms of dementia

March 7th, 2008 by Richard Brassaw

Today positron emission tomography (PET) imaging is commonly used to differentiate various forms of dementia. The limitation of PET scans is that it only looks at the surface of the brain, which reduces the accuracy in determining the type of dementia the patient has developed. Lisa Mosconi, PhD, assistant professor of psychiatry, New York University School [...]

Are Alzheimer’s patients better off knowing their diagnosis?

March 4th, 2008 by Richard Brassaw

Physicians often have to grapple with the question if their patients are better off knowing their diagnosis of a life-changing disease or should the information be kept from them so what time they have left will be lived as fully as possible. A 2004 review of research found about half of all physicians were reluctant [...]

Alzheimer’s may be related to cancer protein

February 29th, 2008 by Richard Brassaw

The tau protein is thought to poison nerve cells in the brain, which is one of the hallmarks of Alzheimer’s disease. Chad Dickey, PhD, assistant professor of molecular pharmacology and physiology, University of South Florida (USF), has found that cancer related protein Akt may influence the fate of the tau protein that leads to bundles [...]

Advanced dementia patients and antibiotic use

February 26th, 2008 by Richard Brassaw

At the end of the lives of the more than 5 million Americans with dementia approximately 70% of them will live in nursing homes. Common among these patients are recurrent infections and fever. Erika D’Agata, M.D., M.P.H., Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, studied 214 residents in 21 nursing homes with advanced [...]
