BEIJING, Nov. 28 (Xinhuanet) -- Scientists in Canada have raised a prospect of reversing Alzheimer's disease by deep brain stimulation, according to media reports Monday.The technique here is known as deep brain stimulation -- applying electricity directly to regions of the brain. It has been used in tens of thousands of patients with Parkinson's as well as having an emerging role in Tourette's Syndrome and depression.The study at the University of Toronto took six patients with the condition. Deep brain stimulation was applied to the fornix -- a part of the brain which passes messages onto the hippocampus.Lead researcher Prof Andres Lozano said you would expect the hippocampus to shrink by five per cent on average in a year in patients with Alzheimer's.After 12 months of stimulation, he said one patient had a five per cent increase and another had an eight per cent increase.Prof Lozano told BBC: "This is the first time that brain stimulation in a human being has been shown to grow an area of your brain.""It was an amazing finding for us," he said.The findings were presented at the Society for Neuroscience conference in November but they have yet to be published in an academic journal.To test whether this is really working, rather than being a fluke result, the researchers are going to perform a larger trial.

BEIJING, Sept. 30 (Xinhuanet) -- Tobacco companies concealed the knowledge of radioactive substance in cigarettes from public for over four decades, a new study revealed.The revelation was made by a research team from the University of California, Los Angeles, published on Thursday in the online edition of the U.S. medical journal Nicotine and Tobacco Research.The researchers analyzed 27 timeworn documents and discovered that tobacco companies had knew the existence of polonium-210, a hazardous radioactive substance, in the tobacco since 1959.The companies studied polonium-210 throughout the 1960s, and concealed their findings about the carcinogenic potential of the radioactive substance.Hrayr Karagueuzian, the study's lead author, said the tobacco companies' deception surprised him.According to the revelation, the companies had knew the "cancerous growths" in the lungs of smokers, and even calculated how much radiation a regular smoker would inhale over 20 years.Karagueuzian and his team conducted again the study recorded in the tobacco documents and found that the radiation in cigarettes would cause up to 138 deaths for every 1,000 smokers over a period of 25 years.However, tobacco manufacturer denied that they had concealed the facts from the public.David Sutton, spokesman of Philip Morris, the largest U.S. tobacco company, said the polonium-210 was a "naturally occurring element in the air" and had been widely discussed by the public health community for years.

BEIJING, Sept. 30 (Xinhuanet) -- The number of children being prescribed stimulants to treat attention deficit hyperactivity disorder (ADHD) has been steadily rising in the U.S. since 1996, researchers found.The finding was contained in a report released Wednesday in the U.S. medical journal Psychiatry.About 7.8 percent of children aged 4 to 17 in 2003 were diagnosed with ADHD, compared to 9.5 percent in 2007, according to the data gathered from the Health Resources and Services Administration's National Survey of Children's Health.And compared to 0.6 percent in 1987, 2.9 percent of children under 19 in 2002 have been prescribed stimulants, the report said.The finding raises the researchers' concern as stimulants have side effects such as decreased appetite, leeplessness and even heart-related damage, the report warned."Stimulant medications work well to control ADHD symptoms, but they are only one method of treatment for the condition. Experts estimate that about 60 percent of children with ADHD are treated with medication." says researcher Benedetto Vitiello, MD, of the U.S. National Institute of Mental Health."There is ongoing concern that these drugs may not be used properly, especially when they are prescribed to college students or children in their late adolescence who are more in charge of their care and may not be using the medications as prescribed." he added.
