A Canadian study has confirmed what parents have long suspected: dating, sexual activity and substance use seem to make teens feel older than they really are. And, as adolescents get older, the gap between their chronological age and their self-perceived age widens.
Researchers in the United Kingdom have found that patients with COPD, or chronic obstructive pulmonary disease, have greater arterial stiffness. The researchers also found that those COPD patients with osteoporosis, a common complication of the respiratory disease, had even greater arterial stiffness. These premature signs of aging may explain why COPD patients are at greater risk for cardiovascular disease.
Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer’s disease, report researchers at the Salk Institute for Biological Studies.
Can a fitness program for your brain improve thinking and concentration the way lifting weights can increase muscle strength? Early results from a Wake Forest University Baptist Medical Center study suggest that attention training can change brain activity so older adults can block out distractions and improve concentration.
Mitch Dushay and colleagues at Uppsala University in Sweden report the publication of their paper, “Characterization of lamin Mutation Phenotypes in Drosophila and Comparison to Human Laminopathies,” in the June 13 issue of the online, open-access journal PLoS ONE.
Men and women with diabetes at age 50 and older appear not to live as long overall, or have as many years without cardiovascular disease, than individuals without diabetes, according to a report in the June 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
People who are easily distressed and have more negative emotions are more likely to develop memory problems than more easygoing people, according to a study published in the June 12, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.
The latest worldwide estimate of Alzheimer’s disease prevalence shows that 26.6 million people were living with the disease in 2006, according to research reported today at the 2nd Alzheimer’s Association International Conference on Prevention of Dementia in Washington, DC.
Look at the clock. In the next three minutes, 10 people in America will suffer a coronary event or stroke, and only six of them will survive. According to a recent report by the American Heart Association (AHA), coronary heart disease (CHD) affects more than 15 million Americans; over five million more are affected by stroke.
Alzheimer’s disease researchers may be able to reduce the time and expense associated with clinical trials, according to early results from the Alzheimer?s Disease Neuroimaging Initiative (ADNI), a public-private research partnership organized by the National Institutes of Health. Preliminary results from ADNI show how it might yield improved methods and uniform standards for imaging and biomarker analysis, so these techniques can be employed in the fight against Alzheimer?s disease.
