July 6, 2009 - A new study found that the clinical criteria for mild cognitive impairment is better at predicting who will develop Alzheimers disease than a single memory test. This is one more piece of information to aid in the identification and early treatment of individuals most likely to develop Alzheimers disease.
The goal of this research is to try to predict who is going to develop Alzheimers disease in the future, says Ronald Petersen, M.D., Ph.D., a neurologist at Mayo Clinic and the lead author of this study. Ideally, we'd like to identify individuals before any damage is done in the brain. The sooner we intervene on this process with medications or other therapies, the greater impact we can have on lessening the number of people who will ultimately develop Alzheimers disease.
January 5, 2009 - Experts estimate that 20 percent of women experience excessive or prolonged menstrual bleeding at some time during their lives, particularly as they approach menopause. A new, less invasive procedure called global endometrial ablation (GEA) preserves the uterus, while decreasing menstrual bleeding and shortening patients' recovery time.
According to the Mayo researchers, identifying risk factors that affect treatment outcomes following GEA is an important advance in this field. This knowledge can help surgeons determine whether GEA is appropriate for a specific patient and help them provide patients with better guidance when choosing a treatment option, say researchers.
June 29, 2009 - Celiac disease, an immune system reaction to gluten in the diet, is at least four times as common today as it was 50 years ago, according to findings of a Mayo Clinic study published this month in the journal Gastroenterology. The study also found that subjects who unknowingly had celiac disease were nearly four times as likely as celiac-free subjects to have died during the 45 years of follow-up.
In the video and audio files linked in the article, Joseph Murray, M.D., the Mayo Clinic gastroenterologist who led the study, describes the study findings and provides background on the disease, its symptoms and treatment.
July 23, 2009 - Researchers have found that children exposed to anesthesia during Cesarean delivery are not at any higher risk for later learning disabilities than children not delivered by Cesarean. These findings are recently reported in the journal Anesthesiology.
We found that the incidence of learning disabilities was equal between children who were delivered vaginally and those who were delivered via Cesarean section but with general anesthesia, says Juraj Sprung, M.D., Ph.D., a Mayo Clinic anesthesiologist who led the study. Its reassuring that the anesthetics required for Cesarean delivery do not appear to cause long-term brain problems.
April 27, 2009 - Results of a new Mayo Clinic study support an association between anemia experienced early in life and the development of Parkinsons disease many years later. The findings were presented at the American Academy of Neurology Annual Meeting in Seattle on April 30.
"We were surprised to discover that chronic anemia or low levels of hemoglobin were linked to the risk of Parkinsons disease 20- to 30-years later", says Walter A. Rocca, M.D., an author of the study and a neurologist at the Mayo Clinic.
March 11, 2009 - Mayo Clinic researchers have found that children who require multiple surgeries under anesthesia during their first three years of life are at higher risk to develop learning disabilities later. Several studies have suggested that anesthetic drugs may cause abnormalities in the brains of young animals.
This is the first study in humans to suggest that exposure of children to anesthesia may have similar consequences. The finding is reported in the April 2009 issue of the journal Anesthesiology.
February 02, 2009 - Men who experience erectile dysfunction at a young age - from 40 to 49 - are two times more likely to develop heart disease compared to men without erectile dysfunction, according to a new Mayo Clinic study.
Overall, researchers found that men with erectile dysfunction have an 80 percent higher risk of heart disease compared to those without erectile dysfunction.
August 12, 2008 - A new Mayo Clinic study found that individuals with earlier onset, longer duration and greater severity of diabetes appear to be more likely to have mild cognitive impairment. Mild cognitive impairment (MCI) is a transitional stage between normal aging and the earliest features of Alzheimer's disease.
"There is an obesity epidemic in this country. Since obesity is a risk factor for diabetes, this study provides more evidence of the importance of reducing obesity," said Rosebud Roberts, M.D., a Mayo Clinic epidemiologist and author of this study.
