Does less education mean less ability to recognize Alzheimer's disease onset?

Does less education mean a patient might not recognize the onset of Alzheimer's disease symptoms? A review of epidemiological data has found evidence that people who spend fewer years in school may experience a slight but statistically significant delay in the realization that they're having cognitive problems that could be Alzheimer's disease. more  

Driving proves potentially hazardous for people with early Alzheimer's

A new study by researchers at Rhode Island Hospital and Brown University finds that people with Alzheimer’s Disease (AD) experienced more accidents and performed more poorly on road tests compared to drivers without cognitive impairment. The study is published in the January 23 edition of Neurology, the medical journal of the American Academy of Neurology. more

Genetic difference predicts antidepressant response

Researchers have identified subtle genetic variations that predict the efficacy of two widely used antidepressant drugs. They found that certain variants in the gene for a protective transporter protein that pumps drugs and other substances out of the brain compromise the effectiveness of the antidepressants citalopram (trade name Celexa) and venlafaxine (Effexor). more  

Study raises questions about diagnosis, medical treatment of ADHD

A new UCLA study shows that only about half of children diagnosed with attention-deficit hyperactivity disorder, or ADHD, exhibit the cognitive defects commonly associated with the condition. more

Regular, long-term aspirin use reduces risk of colorectal cancer  

The use of regular, long-term aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) reduces the risk associated with colorectal cancer, according to a study published in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. However, the use of aspirin for chemoprevention of colorectal cancer may require using the drug at doses that are higher than recommended over a long period of time, which may cause serious side effects including gastrointestinal bleeding. more

Countering tobacco use among young adults: new approaches needed  

For the tobacco industry, a 22-year-old who isn't a smoker represents a challenge but also an opportunity. The reason: While most - but by no means all - smokers start as teenagers, only about one-third are fully addicted smokers by age 18. Young adulthood, typically defined as ages 18 to 25, is when many transition from light smokers to heavy smokers - or quit. If smoking hasn't taken root by age 25, studies show, chances are good it's not going to. more

Researchers uncover errors in immature brain cells in lab and animal studies that may promote the growth of some brain tumors

In experiments done in lab and animal studies, a breakdown in proper cell development has been shown to cause brain-specific stem cells to become starter seeds for aggressive brain tumors called glioblastoma multiforme, according to research from a team of researchers at the National Cancer Institute (NCI) and the National Institute of Neurological Disease and Stroke (NINDS), parts of the National Institutes of Health (NIH). more
