Sex, race and dementia may influence risk of mortality in patients with PD

Demographics and clinical factors appear to be associated with survival in patients with Parkinson disease (PD), and the presence of dementia is associated with a significant increase in mortality, according to a report in the January issue of Archives of Neurology, one of the JAMA/Archives journals.

CSF Aβ42 levels appear to be decreased before patients with MCI develop AD dementia

Cerebrospinal fluid levels of Aβ42 appear to be decreased at least five to 10 years before some patients with mild cognitive impairment develop Alzheimer disease (AD) dementia whereas other spinal fluid levels seem to be later markers of disease, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Glia cells also regulate learning and memory

Glia cells, named for the Greek word for "glue," hold the brain's neurons together and protect the cells that determine our thoughts and behaviors, but scientists have long puzzled over their prominence in the activities of the brain dedicated to learning and memory.

Prion protein uptake associated with development of Scrapie disease

Scrapie is a neurodegenerative disease which can function as a model for other diseases caused by an accumulation of proteins resulting in tissue malformations (proteinpathies), such as Alzheimer's and Parkinson's disease.

Healthy diet keeps the brain sharp

The study shows that elderly who followed this diet had less of the brain shrinkage linked with Alzheimer's disease and scored better on mental and thinking tests than those with poorer diets. Although previous studies have suggested that a heart-healthy diet is also good for the brain, the new study took a different approach by using blood tests to determine the participant’s diet and nutrient levels.

Silent strokes linked to memory loss in the elderly

New research links 'silent strokes,' or small spots of dead brain cells, found in about one out of four older adults to memory loss in the elderly. The study is published in the January 3, 2012, print issue of Neurology-, the medical journal of the American Academy of Neurology.

Seniors with higher levels of vitamins and omega 3 fatty acids perform better on mental acuity tests

New research has found that elderly people with higher levels of several vitamins and omega 3 fatty acids in their blood had better performance on mental acuity tests and less of the brain shrinkage typical of Alzheimer's disease - while "junk food" diets produced just the opposite result.

Diets high in vitamins or omega 3 fatty acids reduce brain shrinkage

People with diets high in several vitamins or in omega 3 fatty acids are less likely to have the brain shrinkage associated with Alzheimer's disease than people whose diets are not high in those nutrients, according to a new study published in the December 28, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Researchers decode and characterize DNA repair mechanism

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations in the DNA.

Transparency needed in clinical trial recruitment performance

Despite the importance of site investigators to the success of multicentre clinical trials, inadequate public information is available about their recruitment performance. In this week's PLoS Medicine, Rafael Dal-R- and colleagues argue that that sponsors should disclose the recruitment targets of all site investigators on ClinicalTrials.gov before a trial starts, as well as their final recruitment.

Early Alzheimer’s detection - cost effective and easy

Boston researchers have reported a new method for detecting subtle brain changes in people who have no memory problems but who may already be in the earliest stages of Alzheimer’s disease.

President Obama to provide federal funding for Alzheimer's programs

As the world's leading voluntary health organization advocating for Alzheimer's care, support and research, the Alzheimer's Association is pleased that Congress and President Obama have responded to calls by the Alzheimer's Association on behalf of people with Alzheimer's disease, caregivers, health professionals and researchers, to provide federal funding for several programs critical to the Alzheimer's community.

UVA outreach librarian receives national award

Whether helping cancer patients find accurate information or caregivers for Alzheimer's patients overcome a sense of isolation, Ann Duesing has spent 16 years connecting Southwest Virginia residents with information to help them live healthier lives.

Cleveland Clinic scientists named AAAS Fellows

Cleveland Clinic researchers Bruce Lamb, Ph.D., and Xiaoxia Li, Ph.D., were recently named Fellows of the American Association for the Advancement of Science.

Neuroscientists discover gene responsible for HDLS

A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids.

Researchers discover key interaction at heart of promising new treatment for Fabry disease

A research team led by biochemist Scott Garman at the University of Massachusetts Amherst has discovered a key interaction at the heart of a promising new treatment for a rare childhood metabolic disorder known as Fabry disease.

Radiology researchers discover that MS affects thalamus of the brain

Radiology researchers at The University of Texas Health Science Center at Houston (UTHealth) have found evidence that multiple sclerosis affects an area of the brain that controls cognitive, sensory and motor functioning apart from the disabling damage caused by the disease's visible lesions.
