Despite scores of studies documenting the effects of healthful plant nutrients called polyphenols in protecting nerves from damage, it would be "unwise" to assume that the same protective effects occur for Alzheimer's disease (AD) and other human disorders, a new report concludes.

Overactivation of proteins known as calpains, which are involved in memory formation, has been linked to Alzheimer disease.

Research in fruit flies has shown that enhancing the production of a protein called neprilysin can reduce the formation of plaques and neuron death associated with Alzheimer's, at the expense of reducing the flies' lifespan.

Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.

Brain destruction in Alzheimer's disease is caused by the build-up of a protein called amyloid beta in the brain, which triggers damaging inflammation and the destruction of nerve cells. Scientists had previously shown that preventing individual amyloid beta proteins from sticking to one another minimized brain lesions and protected nerve cells against damage.

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

A commonly recognized gene that places one at risk for Alzheimer's disease does not discriminate between blacks and whites, according to new research led by Florida State University.

Mount Sinai researchers have discovered that polyphenolics derived from red grape seeds may be useful agents to prevent or treat Alzheimer's disease (AD).

Researchers are actively cutting the time and cost it normally takes to develop radiopharmaceuticals by taking advantage of "Exploratory Investigational New Drug" (ExpIND), an FDA-sanctioned procedure that enhances post-discovery drug development while observing scientific and patient safety standards.

In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years.

Old muscle got a shot of youthful vigor in a stem cell experiment by bioengineers at the University of California, Berkeley, setting the path for research on new treatments for age-related degenerative conditions such as muscle atrophy or Alzheimer's and Parkinson's diseases.

Increases in total sleep time related to the treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) are associated with improvements in cognition in patients with Alzheimer disease, according to a research abstract that will be presented on Tuesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
