Jayme Deerwester USA TODAY Published 3:19 PM EDT Sep 28, 2018 CNN founder Ted Turner has revealed that he is suffering from Lewy body dementia, the same form of dementia that Robin Williams battled in the last few years of his life. According to the website for the Lewy Body Dementia Association, LBD affects 1.5 million Americans. It is a progressive neurological disorder that affects a patient's memory, cognition (especially decision making), mood, behavior and balance and is often misdiagnosed as Parkinson's, as Williams' case was, or bipolar disorder, as Turner's was. In an interview with Ted Koppel set to air on "CBS Sunday Morning" this weekend (9 a.m. EDT/PDT), Turner, 79, likened his case to a "mild case of Alzheimer's ... but not nearly as bad ... Thank goodness, I don't have that." Displaying some of the memory problems characterized by LBD, he struggled to remember the name of his disorder, "I also have got, let's – the one … [Read more...] about Ted Turner has Lewy body dementia: What is the neurological disorder?
Smell test for dementia
Alzheimer's disease is difficult to diagnose before symptoms start showing up, because there is no single test that can definitively determine whether a person has the degenerative brain disease. Could a scoop of peanut butter and a ruler become that elusive test? That's what researchers at the University of Florida's McKnight Brain Institute Center for Smell and Taste are hoping. They found patients with early-stage Alzheimer's disease had more difficulty smelling peanut butter held at short distances from their nose than people without the disease. "At the moment, we can use this test to confirm diagnosis," graduate student Jennifer Stamps, who led the research, said in a statement. "But we plan to study patients with mild cognitive impairment to see if this test might be used to predict which patients are going to get Alzheimer's disease." About 5.2 million Americans have Alzheimer's or another form of dementia, according to the Alzheimer's Association, with about 13.8 million … [Read more...] about CBS News Logo Cheap Alzheimer’s test made from peanut butter and ruler, researchers report
New research suggests that a faltering sense of smell might signal the early stages of Alzheimer's disease, and that an inexpensive, low-tech smell test could spot who needs more extensive screening for dementia. In two different studies, the decreased ability to identify odors was associated with the loss of brain cell function and progression to Alzheimer's disease. "We're trying to be able to diagnose Alzheimer's earlier and theoretically deliver drugs to people sooner," said Matthew Growdon, lead author of one of the studies. "Think about cardiovascular disease as a paradigm; the idea is that we would find a way to control the risk factors [before the disease advances]." The ability to smell is associated with the first cranial nerve, and is often one of the first things to be affected by cognitive decline. Brain regions that process odors are particularly vulnerable to Alzheimer's early in the disease process, explained Growdon, who is a student at Harvard Medical School, in … [Read more...] about CBS News Logo Smell test may detect early stages of Alzheimer’s disease, studies show
People who have problems with their sense of smell may be at increased risk for dying sooner than those who don't have trouble smelling, a new study suggests. Researchers analyzed information from more than 1,100 adults in New York City whose average age was 80. The participants took a "scratch and sniff" test in which they attempted to identify 40 common odors. People who scored less than 18 points out of 40 were said to have anosmia, or an inability to smell. The study found that the people with scores in the low range (zero to 20 points) were nearly four times more likely to die over a four-year period than those with scores in the high range (31 to 40 points). About 45 percent of participants with scores in the low range died during the study period, compared with 18 percent of those with scores in the high range. [7 Ways the Mind and Body Change with Age] The results held even after the researchers took into account factors that could affect people's risk of death, such as age, … [Read more...] about CBS News Logo Losing sense of smell linked to earlier death
Last Updated Jul 26, 2016 11:41 AM EDT Memory loss may not always be the first warning sign that dementia is brewing -- changes in behavior or personality might be an early clue.Researchers on Sunday outlined a syndrome called "mild behavioral impairment" that may be a harbinger of Alzheimer's or other dementias, and proposed a checklist of symptoms to alert doctors and families, including:Losing interest in favorite activitiesGetting unusually anxious, aggressive or suspiciousSuddenly making crude comments in public"Historically, those symptoms have been written off as a psychiatric issue, or as just part of aging," said Dr. Zahinoor Ismail of the University of Calgary, who presented the checklist at the Alzheimer's Association International Conference in Toronto.Now, "when it comes to early detection, memory symptoms don't have the corner on the market anymore," he said.Alzheimer's, the most common form of dementia, affects more than 5 million people in the U.S., a number growing as … [Read more...] about CBS News Logo Memory loss is not necessarily the first sign of dementia
