PHOENIX — A smell test could someday be one of the tools to screen for people at risk of developing Parkinson’s disease, according to a new Mayo Clinic study.
Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while tremor may be the best-known sign of Parkinson's, the disorder also commonly causes stiffness and slowing of movement. Additionally, there are many non-movement problems, including constipation, loss of the sense of smell, sleep problems, lightheadedness, urinary difficulties, depression and anxiety. The non-movement symptoms can develop many years before movement disorders.
Although Parkinson's disease can't be cured, medications may markedly improve symptoms. Currently, there is no accurate diagnostic test for the disease; diagnosis is based on medical history, a review of signs and symptoms, a neurological and physical examination and by ruling out other conditions. Confirmation of the disease can only be made by performing an autopsy. Read the rest of this entry »

JACKSONVILLE, Fla. — Mayo Clinic’s stroke center in Jacksonville is the first center in Florida to receive national Comprehensive Stroke Center certification, joining an elite group of centers throughout the United States that are focused on providing advanced and complex stroke care.
Centers that achieve this distinction — awarded by The Joint Commission working with the American Heart Association and the American Stroke Association — are recognized as leaders that help set the national agenda in highly specialized stroke care. The Joint Commission is the nation's oldest and largest standards-setting and accrediting body in health care.

We have all experienced the annoying, relentless and throbbing pain associated with a headache. They can slow us down or even bring us to a complete stop. However, did you know that there are several different types of headaches, and knowing the type you've got can be the first step in effectively treating it?

PHOENIX — A new Mayo Clinic study suggests that the care and support family members give to elderly widows following the death of their spouse may be a factor in delaying dementia.
The study presented at the Alzheimer’s Association International Conference in Copenhagen, Denmark last week was designed to evaluate the effects of widowhood in people with mild cognitive impairment - a precursor of dementia. The thinking had been that widowhood would accelerate the development of dementia in people with MCI but the study showed the opposite.
Mayo Clinic researchers used data on more than 3,500 people from the National Alzheimer’s Coordinating Center database, which compiles information collected at various Alzheimer’s disease Centers in the U.S. The researchers found that of the 1,078 subjects who developed dementia, people who remained married developed dementia at a younger age than those who were widowed (83 years old versus 92 years).

A Third Protein Provides Clue
Since the time of Dr. Alois Alzheimer himself, two proteins (beta-amyloid (Aβ) and tau) have become tantamount to Alzheimer’s disease (AD). But a Mayo Clinic study challenges the perception that these are the only important proteins accounting for the clinical features of the devastating disease.
In a large clinico-imaging pathological study, Mayo Clinic researchers demonstrated that a third protein (TDP-43) plays a major role in AD pathology. In fact, people whose brain was TDP positive were 10 times more likely to be cognitively impaired at death compared to those who didn’t have the protein, showing that TDP-43 has the potential to overpower what has been termed resilient brain aging. The study was published in the journal Acta Neuropathologica.

PHOENIX — In response to growing concerns about concussions and head injuries in youth sports, Arizona Pop Warner Football and Cheer and Mayo Clinic have announced a groundbreaking collaboration that will provide intensive medical research about the effects of sports-related injuries. As part of the program, all participants ages 10 years and older in Arizona Pop Warner’s flag and tackle football programs, as well as all participants in the organization’s cheerleading programs, will be required to complete a comprehensive evaluation prior to play that will provide a baseline for future testing in the event of an injury. This baseline evaluation will provide immediate data when testing young athletes after an injury, helping physicians determine the nature and extent of the injury and helping to assess a timeline for return to competition.
David Dodick, M.D., a neurologist at Mayo Clinic in Arizona and an expert in concussion care and director of the Mayo Clinic Concussion Program, was invited to join President Barack Obama and other medical experts at the White House in late May. The effort between Arizona Pop Warner Football and Cheer and Mayo Clinic is one of the first of its kind since President Obama’s call-to-action on May 29 at the White House, assembling prominent athletic organizations, athletes and medical experts to join the Healthy Kids & Safe Sports Concussion Summit. The two organizations are working to get the concussion protocol executed before the start of the 2014 season.
