Millions of acupuncture needles are due for a major upgrade and signs of Alzheimers disease may show up years before diagnosis.
People with a strong family history of Alzheimer's disease may show signs of the disease on brain scans decades before symptoms appear. That's according to a new study from NYU school of Medicine. Researchers found patients who had two parents with Alzheimer's had more brain plaques and abnormal brain volume.
 
Kids who take medication to treat attention deficit hyperactivity disorder are "not" at increased risk for stroke. A study of two and a half million children presented at the American Stroke Association found no link between ADHD medication and strokes.
 
And researchers say the quality of acupuncture needles needs to improve. Australian scientists found surface irregularities and bent tips in some needles which they say could cause skin reactions or pain. An estimated 1.4-billion needles are used in acupuncture worldwide each year with most manufactured in China, Japan, and Korea.
