Two of the world's leading Alzheimer's researchers have co-edited a book critically synthesizing the major new developments in the diagnosis and treatment of Alzheimer's disease. Building upon a 2007 Alzheimer's disease conference held in Chile, George Perry, dean of the College of Sciences at The University of Texas at San Antonio (UTSA) and Ricardo B. Maccioni, neurology professor at The University of Chile Medical School have edited "Current Hypotheses and Research Milestones in Alzheimer's Disease," a 254-page text written by academics and medical doctors. The book focuses on the most promising hypotheses that illuminate the path to more effective treatment.

Highlights include:
- new information about the biology of amyloid-ß, the main component in the amyloid plaques found in the brains of Alzheimer's disease patients, and where the field has concentrated its efforts for nearly 20 years

- the Tau Hypothesis, which suggests Alzheimer's disease is caused by abnormal chemical changes to tau proteins disrupting the normal cell biology of neurons

- the Oxidative Stress Hypothesis, which indicates neurons degenerate and die because the brains of patients with Alzheimer's disease have a disrupted oxidative metabolism leading to decreased neuronal energy supply and increased oxidative damage

- neuroimmunological hypotheses linking Alzheimer's disease to the chronic low level inflammation thought to underlie arthritis, coronary disease and other age-related conditions

- the development of biomarkers for early diagnosis

- new horizons for the development of anti-dementia drugs.

"Alzheimer's disease is the leading cause of dementia in senior citizens," said Perry, also a professor in UTSA's Department of Biology. "While the scientific community hasn't been able to pinpoint the cause of the disease, researchers around the world are advancing what we know about the disease and how we might be able to treat it in the future." ... http://www.medicalnewstoday.com
