Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002. Higher levels of education were associated with better cognitive health. – Higher levels of health education improved cognitive health among older Americans. Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002.

Gene identified for hair loss in hypotrichosis simplex

New gene improves our understanding of hair growth and offers a path to effective therapies. Research findings will lead to new therapies that will work with various forms of hair loss. – A healthy individual loses around a hundred hairs a day. Nothing to worry about as long as they are constantly replaced and the losses occur evenly around the whole scalp. But when hair loss goes well beyond this level it can become quite a problem for those affected ? not only superficially in terms of looks but also psychologically.

Memory loss, less common in older Americans

Good news on gray matter: Memory loss and other cognitive impairment becoming less common in older Americans, U-M study finds; Better education, finances & cardiovascular care may be boosting brain health. – It appears that memory loss and thinking problems are becoming less common among older Americans. A new study shows a downward trend in the rate of “cognitive impairment” – the umbrella term for everything from significant memory loss to dementia and Alzheimer’s disease – among people aged 70 and older.

Cholesterol drug statins may reduce heart’s atrial fibrillation

Special issue of JACC features intriguing link between statins and Atrial Fibrillation (AF) prevention, tools to ensure the highest-quality AF care, and more. – When we’re young, a racing heart often means love is in the air. If you’re a “baby boomer,” it might mean you’ve just joined the 2.2 million Americans who have atrial fibrillation (AF), an irregularity in the heart’s rhythm that grows more common as we age and markedly increases the risk for stroke.

Do animals think like autistic savants?

Autism gives special insight into the inner workings of the animal mind. – When Temple Grandin argued that animals and autistic savants share cognitive similarities in her best-selling book Animals in Translation (2005), the idea gained steam outside the community of cognitive neuroscientists.

Music listening improves stroke patients’ recovery

Listening to music in the early stages after a stroke can improve patients’ recovery, according to new research published online in the medical journal Brain – Researchers from Finland found that if stroke patients listened to music for a couple of hours a day, their verbal memory and focused attention recovered better and they had a more positive mood than patients who did not listen to anything or who listened to audio books.

Stem cells may aid stroke recovery

Human embryonic stem cell-based therapies have the potential to help treat stroke disease. – Neural cells derived from human embryonic stem cells helped repair stroke-related damage in the brains of rats and led to improvements in their physical abilities, according to a new study by researchers at the Stanford University School of Medicine.

Herpes virus link to complications in pregnancy

Exposure to viral infection – especially viruses of the herpes group – may be associated with pregnancy-induced hypertensive disease (pre-eclampsia) and also with pre-term birth. – Viral infection with high blood pressure during pregnancy may lead to pre-term birth, revealed by researchers at Adelaide’s Women’s & Children’s Hospital and the University of Adelaide.
