General public fails to recognise early signs of stroke
April 30, 2002The general public does not find it easy to recognise the early symptoms of stroke because they vary so much, and this often results in delay in seeking medical attention, finds a study in this week’s BMJ.
Thirty-five people took part in discussion groups and answered questionnaires about stroke: 11 from the general public, 14 people who had had a stroke, and 10 carers or partners.
Participants reported that recognising symptoms was not easy. Many patients who had had a stroke did not initially take their symptoms seriously because the symptoms were not the same as those they had read about.
They felt that none of the available written information about stroke successfully conveyed the importance of early presentation to hospital for anyone experiencing warning signs or symptoms. They stressed the need for simple, understandable information about stroke.
For maximum effect, treatment of acute stroke with anti-clotting drugs must be given within an early limited time, say the authors. Unless people know they are or might be having a stroke that opportunity will be missed, they conclude.

Stroke Current Events and Stroke News RSSSurgery not linked to memory problems in older patients
For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study from researchers at Washington University School of Medicine in St. Louis questions those assumptions.
Pushing the brain to find new pathways
Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities.
Night Beat, Overtime and a Disrupted Sleep Pattern Can Harm Officers' Health
A police officer who works the night shift, typically from 8 p.m. to 4 a.m., already is at a disadvantage when it comes to getting a good "night's" sleep.
Vitamin B niacin offers no extra benefit to statin therapy in seniors already diagnosed with CAD
The routine prescription of extended-release niacin, a B vitamin (1,500 milligrams daily), in combination with traditional cholesterol-lowering therapy offers no extra benefit in correcting arterial narrowing and diminishing plaque buildup in seniors who already have coronary artery disease, a new vascular imaging study from Johns Hopkins experts shows.
The benefits of exercise
Physical exercise is one of the most effective methods of preventing disease. The current issue of Deutsches Arzteblatt International is devoted to this important topic.
Heart and bone damage from low vitamin D tied to declines in sex hormones
Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone.
New study links vitamin D deficiency to cardiovascular disease and death
While mothers have known that feeding their kids milk builds strong bones, a new study by researchers at the Heart Institute at Intermountain Medical Center in Salt Lake City suggests that Vitamin D contributes to a strong and healthy heart as well - and that inadequate levels of the vitamin may significantly increase a person's risk of stroke, heart disease, and death, even among people who've never had heart disease.
Early end to key study on benefits of niacin, a B vitamin, in keeping arteries open was premature
Heart experts at Johns Hopkins are calling premature the early halt of a study by researchers at Walter Reed Army Medical Center and Washington Hospital Center on the benefits of combining extended-release niacin, a B vitamin, with cholesterol-lowering statin medications to prevent blood vessel narrowing.
Study finds many people with hemianopia have difficulty detecting pedestrians while driving, advocates for individual testing
Schepens Eye Research Institute scientists have found that--when tested in a driving simulator--patients with hemianopia (blindness in one half of the visual field in both eyes) have significantly more difficulty detecting pedestrians (on their blind side) than normally sighted people.
Texas Children's discharges first pediatric patient with implanted mechanical heart device
Texas Children's Hospital is the nation's first pediatric hospital to discharge a child while on an intracorporeal ventricular assist device (VAD), a feat previously accomplished only at adult institutions.

Is This It by The Strokes With all the media hype that dogged the Strokes before the release of their debut album, it's rather apt that they chose the title Is This It. On the strength of just five songs released on two singles, the Strokes were being hailed as everything from the saviors of rock & roll to the Savior himself. Surely, few bands could live up to the impossibly high standards set for this young five-piece, but the band needn't have worried: Is This It is one of the most exciting and energetic debut albums to spring from New York's long-dormant club scene. In fact, the Strokes are a New York City band through and through; like the Velvet Underground, these are a bunch of uptown artsy types elegantly slumming downtown to the tried and tested themes of sex, drugs, and rock & roll.

Room on Fire by The Strokes An acclaimed debut prompts one of two kinds of follow-ups: either the band strives to broaden their palate or they attempt to deepen the colors they splashed all over that heralded first effort. The Strokes' second outing falls in the latter camp. In the tradition of the Ramones' Leave Home and Oasis' (What's the Story) Morning Glory, the Strokes largely stay the course with their second full-length release, producing an album that won't cause the stir that its predecessor did, but has a sneaky appeal all its own. Thanks to the quintet's Lower East Side roots, Velvet Underground and Television references abound with these guys, but Boston new wavers the Cars, and in particular their hit-heavy second album, 1979's Candy-O, provide a more suitable point of reference for Room on Fire.

My Stroke of Insight: A Brain Scientist's Personal Journey by Ph.D., Jill Bolte Taylor (Author) The astonishing New York Times bestseller that chronicles how a brain scientist's own stroke led to enlightenment On December 10, 1996, Jill Bolte Taylor, a thirty-seven- year-old Harvard-trained brain scientist experienced a massive stroke in the left hemisphere of her brain. As she observed her mind deteriorate to the point that she could not walk, talk, read, write, or recall any of her life-all within four hours-Taylor alternated between the euphoria of the intuitive and kinesthetic right brain, in which she felt a sense of complete well-being and peace, and the logical, sequential left brain, which recognized she was having a stroke and enabled her to seek help before she was completely lost. It would take her eight years to fully recover. For Taylor, her stroke was a... |

First Impressions of Earth by The Strokes Their prospects dangerously over-inflated by pundits who often hailed their debut as nothing short of rock-messianic, New York City's Strokes got a lesson in cynical rock-press dynamics when their biz-troubled, if similarly toned, '03 follow-up was dutifully dismissed as the proverbial sophomore slump. A lesser band might have been chastened by the experience; this one responds with a third album that positively bristles with energetic challenges. Revolving around a loose concept that allows songwriter/frontman Julian Casablancas to adopt a viewpoint that's as detached as it is world-weary and bemused, it's a record that quickly trades the often precious production conceits of its forebears for a muscular confidence that's notable from the infectious, back-to-the-'80s opener "You Only... |
