Prefrontal cortex in the brain damaged by both alcoholism and chronic smoking

Alcoholism is commonly associated with chronic smoking, and both alcohol and nicotine are believed to act on the same brain region. Research builds upon previous research that identified four potential alcohol-sensitive genes in the prefrontal cortex, finding that smoking also influences the expression of these genes.

Doctors must listen when patients talk of a failing memory

A team at the Aging and Memory Research Center, Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles, has found that a higher self awareness of memory difficulties may be associated with brain function decline over time, particularly in older adults with a genetic risk for Alzheimer's disease.

Higher self awareness of memory difficulties may be associated with brain function decline over time

Published in the April issue of the Archives of General Psychiatry, the study offers a greater understanding of how different types and varying degrees of memory complaints may relate to brain function decline, a finding that may lead to early treatment interventions for people who could develop Alzheimer's disease.

Genetic clues to longevity

In a new study, Drs. Gil Atzmon and Nir Barzilai at the Albert Einstein College of Medicine of Yeshiva University have found that people harbor alleles--alternative forms of a gene--that confer the same sort of longevity advantage.

Ernst Mayr's theory illustrated in genetic epidemiology studies

The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors.

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

Research may help explain Alzheimer's memory loss

Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name.

Gene that increases risk for Alzheimer's disease

An international team of researchers, led by investigators at Washington University School of Medicine in St. Louis, are zeroing in on a gene that increases risk for Alzheimer's disease. They have identified a region of chromosome 10 that appears to be involved in risk for the disease that currently affects an estimated 4.5 million Americans.

Myelin breakdown appears to be key contributor to Alzheimer disease later in life

A new UCLA imaging study shows that age-related breakdown of myelin, the fatty insulation coating the brain's internal wiring, correlates strongly with the presence of a key genetic risk factor for Alzheimer disease.

Decaffeinated coffee may cause an increase in harmful LDL cholesterol

Decaffeinated -- not caffeinated -- coffee may cause an increase in harmful LDL cholesterol by increasing a specific type of blood fat linked to the metabolic syndrome, hints a new study presented at the American Heart Association's Scientific Sessions 2005.

HDLs provide human immunity to certain parasites

For years biomedical researchers have known that high density lipoproteins, commonly called HDLs or "good cholesterol," are responsible for protecting humans from certain parasites, but couldn't explain how.

Women with defects in lipoprotein metabolism may actually be able to bear children without complications

A group of Belgian researchers has determined that a pregnant woman's ability to metabolize fats is determined not only by her genes but by her baby's genes as well.

No increase in anxiety or depression when children of people with Alzheimer's get genetic testing

Adult children of people with Alzheimer’s disease were satisfied and unharmed by the experience of genetic risk assessment, even when results suggested they might be at risk, according to a new study presented at the first Alzheimer’s Association’s International Conference on the Prevention of Dementia.

Two common gene variations are associated with the risk for developing chronic kidney disease

Two common gene variations are associated with the risk for developing chronic kidney disease, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. One variant increases risk and the other decreases risk with a similar effect in whites, African-Americans, diabetic and non-diabetic individuals.

Muraglitazar lowers blood glucose and helps dyslipidemia seen in diabetes

A novel compound provides long-term lowering of blood glucose levels and improves plasma lipids (fats) that are often a problem in people with type 2 diabetes -- all in a once-daily pill, according to a report presented today at the American Diabetes Association's 65th Annual Scientific Sessions.

Researchers identify marker of heart disease in low-birthweight babies

Some low birth weight infants have large particles rich in apolipoprotein C-1, a blood protein that could put them at risk for heart disease later in life, according to a national study led by Johns Hopkins Children's Center researchers.

Neurologists may have foot in the door to preventing Alzheimer’s before it starts

A study led by Mayo Clinic shows for the first time that a drug appears to have a slowing effect -- though limited -- on the progression from mild cognitive impairment to Alzheimer's disease. The findings will be published online in the New England Journal of Medicine on April 14.

Clinical diagnosis of Alzheimer's may be delayed

In a study of people with mild cognitive impairment (MCI), those who took the drug donepezil were at reduced risk of progressing to a diagnosis of Alzheimer's disease (AD) during the first year of the trial, but by the end of the 3-year study there was no benefit from the drug. Vitamin E was also tested in the study and was found to have no effect at any time point in the study when compared with placebo.
