Alzheimer’s disease (AD) is the most common form of dementia, a neurologic disease characterized by loss of mental ability severe enough to interfere with normal activities of daily living, lasting at least six months, and not present from birth. AD usually occurs in old age, and is marked by a decline in cognitive functions such as remembering, reasoning, and planning.
Copper identified as culprit in Alzheimer’s disease – Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer’s disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain.
Older age at retirement is associated with reduced risk of dementia – Some research has suggested that intellectual stimulation and mental engagement throughout life may be protective against Alzheimer’s disease and other dementias. In a new study, researchers found that retirement at older age is associated with a reduced risk of dementia.
Stem cell transplant restores memory, learning in mice – A study at the University of Wisconsin-Madison is the first to show that human stem cells can successfully implant themselves in the brain and then heal neurological deficits, says senior author Su-Chun Zhang, a professor of neuroscience and neurology.
Cholesterol increases risk of Alzheimer’s and heart disease – High levels of blood cholesterol increase the risk of both Alzheimer’s disease and heart disease, but it has been unclear exactly how cholesterol damages the brain to promote Alzheimer’s disease and blood vessels to promote atherosclerosis.
NIH-supported study finds U.S. dementia care costs as high as $215 billion in 2010 — Formal and unpaid dementia care costs are tallied – The costs of caring for people with dementia in the United States in 2010 were between $159 billion to $215 billion, and those costs could rise dramatically with the increase in the numbers of older people in coming decades, according to estimates by researchers at RAND Corp. and the University of Michigan, Ann Arbor.
Barack Obama launched a plan to map the human brain, in an attempt to find vital clues for treating diseases such as Parkinson’s disease, Alzheimer’s disease and other brain disorders. – US President Barack Obama unveiled a bold new research initiative designed to revolutionize understanding of the human brain. Launched with approximately $100 million in the President’s Fiscal Year 2014 Budget, the BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative ultimately aims to help researchers find new ways to treat, cure, and even prevent brain disorders, such as Alzheimer’s disease, epilepsy, and traumatic brain injury.
Rush scientists identify buphenyl as a possible drug for Alzheimer’s disease – Buphenyl, an FDA-approved medication for hyperammonemia, may protect memory and prevent the progression of Alzheimer’s disease. Hyperammonemia is a life-threatening condition that can affect patients at any age. It is caused by abnormal, high levels of ammonia in the blood.
Anti-aging drug breakthrough — potential to prevent age-related diseases and extend lifespans – Drugs that combat ageing may be available within five years, following landmark work led by an Australian researcher. The study finally proves that a single anti-ageing enzyme in the body can be targeted, with the potential to prevent age-related diseases and extend lifespans.
Merck Initiates Phase II/III Study of Investigational BACE Inhibitor, MK-8931, for Treatment of Alzheimer’s Disease – Although several pharmaceutical companies in US have experienced setbacks with Alzheimer’s compounds, Merck & Co., Inc. hopes to defy the odds with plans to take a Alzheimer pill into a Phase II/III clinical study with patients who suffer from mild-to-moderate stages of the Alzheimer’s disease.
Caffeine may block inflammation linked to mild cognitive impairment – Recent studies have linked caffeine consumption to a reduced risk of Alzheimer’s disease, and a new University of Illinois study may be able to explain how this happens. Researchers have discovered a novel signal that activates the brain-based inflammation associated with neurodegenerative diseases, and caffeine appears to block its activity.
