Do You Read All Of Blogs?
Do you read all of the blogs published by medicineworld.org? Many of our bloggers are busy keeping you updated on the various health related topics. We publish the following blogs at this time.

Cancer blog: I manage the cancer blog with lots of help and support form other bloggers. Through this cancer blog my friends and I try to bring stories of hope for patients with cancer. The cancer blog often republishes important blog posts from other cancer related blogs at Medicineworld.org. If you are searching for a blog that covers wide variety of cancer topics, this may be the one for you.

Breast cancer blog: Breast cancer blog is run by Emily and other bloggers and they bring you the latest stories, news and events that are related to breast cancer. Increasing awareness about breast cancer among women and in the general population is the main goal of this breast cancer blog.

Lung cancer blog: Lung cancer blog is managed by Scott with the help of other bloggers. Through this blog Scott and his friends constantly remind the readers about the dangers of smoking. It's a never-ending struggle against this miserable disease with which a social stigma of smoking is associated.

Colon cancer blog: Colon cancer blog is run by Sue and other bloggers. Sue brings a personal touch to the colon cancer blog since her mother died of colon cancer few years ago. She writes about stories, research news and advances in treatment related to colon cancer.

Prostate cancer blog: Prostate cancer is the most common cancer among American men. American Cancer Society estimates that over 230,000 new cases of prostate cancer occur in the United state every year. This important blog about prostate cancer is run by Mark and other bloggers. This blog brings news, stories, and other personal observations related to prostate cancer.

Medicineworld.org publishes a diabetes watch blog and this blog is run by JoAnn other bloggers. This diabetes watch blog brings you the latest in the field of diabetes. This includes personal stories, advances in diagnosis and treatment, and other observations about diabetes. Improving awareness about diabetes is an important mission of this group.

Brain Imaging to Learn if Alzheimer's Can Be Detected Earlier


Brain Imaging to Learn if Alzheimer's Can Be Detected Earlier MRI of Brain
Scientists at Emory University have received a $330,000 grant from the National Institutes of Health (NIH) and other organizations to study the use of brain imaging to identify and treat Alzheimer's disease (AD) at an earlier stage. The multi-center research trial, called the Alzheimer's Disease Neuroimaging Initiative (ADNI), will focus on brain imaging studies (MRI and PET scans) and biomarker tests (tests to detect diseases), together with measurements of memory, thinking, and daily functioning among three different groups of volunteers.

"The goal of the study is to learn how brain imaging can be used most effectively to monitor changes in the brain in Alzheimer's disease," says Allan Levey, MD, PhD, professor and chair of neurology, Emory University School of Medicine and lead investigator of the ADNI study at Emory. "Most importantly, the study will determine if brain imaging can be used to predict which healthy elderly individuals will develop mild cognitive impairment (MCI), and which individuals with MCI will go on to develop AD."

In recent years, the field of aging and dementia has moved toward trying to identify the earliest clinical signs of the process that is likely to evolve into AD. MCI has come to represent this transitional zone between the cognitive changes of normal aging and very early AD. MCI is most usually described as a subtle but measurable memory disorder. A person with MCI has memory problems greater than normally expected with aging, but does not show other symptoms of dementia, such as impaired judgment or reasoning. Researchers are still working to understand MCI and its relationship to Alzheimer's disease.

To date, this ADNI study is the most comprehensive effort to identify neuroimaging measures and biomarkers associated with cognitive and functional changes in the healthy elderly and those with both MCI and AD.

During the five-year study, scientists at 60 plus sites in the U.S. and Canada will enroll participants in three different groups: a normal control group (200 elderly volunteers who are not having any memory problems); a mild cognitive impairment (MCI) group (400 volunteers with mild memory problems); and an Alzheimer's disease group (200 volunteers with mild Alzheimer's disease). They will be followed over a period of two (AD group) to three (healthy elderly and MCI groups) years.

At Emory, four elderly volunteers who do no have any memory problems will be enrolled; eight volunteers with MCI will be enrolled; and four volunteers with AD will be enrolled.

Since this is the first study of its kind testing MRI and PET for MCI and AD, scientists are interested in learning whether PET scans, 1.5T MRI or 3T MRI will be able to provide a more accurate picture of the brain to help in detecting a change in the structure and function of the brain over time.

Samples of blood and urine will be collected on all study participants. Twenty to 50 percent of the participants will be asked to have their cerebrospinal fluid drawn and tested for changes in brain chemicals. These tests will be studied for biomarkers that might aid in the early diagnosis and be able to track the disease progression of AD and MCI.

The National Institute on Aging, the National Institute of Biomedical Imaging and Bioengineering (both of the NIH), several pharmaceutical companies, the Alzheimer's Association, the Institute for Study of Aging, and the NIH Foundation are all funding this research study.

Men and women from ages 55 to 90 can participate in Alzheimer's Disease Neuroimaging Initiative Study. For more information, call the Emory Alzheimer's Disease Research Center at 404-728-6950.
