Education Staves Off Alzheimer's

But seems to speed progress of disease once it sets in

(Newser) - Higher levels of education help delay the onset of Alzheimer's, but once the disease takes hold, mental decline is faster among those with more schooling, researchers have found. Each year of  education is linked to a 2.5 month delay in accelerated memory loss, according to the study in Neurology....

'Conscientious' Folks Face Lower Risk of Alzheimer's

Dependability appears to reduce threat: study

(Newser) - "Conscientious" people appear to be less likely to get Alzheimer's, researchers have found. Participants whose personality tests pegged them as extremely self-disciplined, goal-oriented and dependable were 89% less likely to get Alzheimer's than those at the opposite end of the diligence spectrum, according to a new study in the...

Critical childhood exposure bodes ill for baby boomers

(Newser) - Women heavily exposed to DDT during childhood are five times more likely to develop breast cancer, according to a new study. Those born between the years 1945 and 1965— when the pesticide was used routinely in the US to kill mosquitoes—likely suffered the greatest exposure, reports the Los Angeles ...

Missing Link in Pneumonia Deaths Found

Antibiotics useless against toxin causing lung infection

(Newser) - Many pneumonia patients die despite receiving treatment, and a new study finds that an infectious toxin unaffected by antibiotics can cause the deaths. One of the researchers involved in the study, published in the journal Immunity, tells Reuters that scientists are working to find a treatment for sometimes-fatal bleeding in...

MRIs Beat Mammograms at Spotting Earliest Breast Cancer

Researchers urge switch to save lives

(Newser) - MRIs significantly outperform mammograms in detecting pockets of abnormal cells that can lead to full-blown breast cancer, and the costly scans should be used routinely to save more women's lives, researchers say. A new study out today says MRIs detected 92% of the early lesions, called ductal carcinoma in situ,...

Scientists Find Fever Trigger in Mice

Discovery of hormone receptor in brain could lead to targeted treatment

(Newser) - Researchers have discovered a fever trigger in lab mice and succeeded in switching it off by removing specific hormone receptors in a tiny spot in the brain. The study is likely to lead to the development of  drugs efficiently targeted to controlling fever, Reuters reports. The trigger is one of...

Electric Stimulation Revives Man in Near-Coma

Case brings hope, raises questions

(Newser) - Electric stimulation may help improve the brain function of patients in a minimally conscious state, a case study reported in Nature reveals. A 38-year-old man who was mute and barely conscious for nearly 6 years is able to name objects, perform precise movements, and eat without the aid of a...

With Parent Away at War, Child Abuse Increases

Stressed women more likely to mistreat kids

(Newser) - Incidents of child abuse and neglect rise significantly when the Army's deployment of one spouse to war leaves the other worried at home, a study finds. An Army-funded report found female spouses four times more likely than males to mistreat their children; the Army has beefed up family-support services to...

Magic bullet hits mutations that prompt 1,800 genetic diseases

(Newser) - A magic bullet that could treat cystic fibrosis, muscular dystrophy, hemophilia and more than 1,800 other genetic disorders could be available by 2009. Lee Sweeney of UPenn, leader of the team developing the drug, tells the Times of London: “It doesn’t just target one mutation that causes...

Bacteria Battle Depression

Research shows brain produces serotonin as an immune response

(Newser) - Clinical depression may be treatable with bacteria, doctors at Bristol University posit. They got the idea when they observed lung cancer patients inoculated with harmless Mycobacterium vaccae who showed reduced symptoms and improved mental health. The brain produces serotonin as an immune response, the docs hypothesized, raising the low serotonin...

Implant Tricks Brain To Lower Blood Pressure

Implant delivers shocks to lower blood pressure

(Newser) - A pacemaker-like implant that relies on small electrical shocks may cut the risk of heart attack and stroke in half for patients with drug-resistant hypertension, a new study shows. The device, which sends electrical shocks through the neck's carotid arteries, tricks the brain into thinking blood pressure is even higher...
