The Working Mother Research Institute surveyed nearly 2,500 women, including more than 1,200 who have cared for a loved one with Alzheimer's, to get a clear picture of how the responsibility of caregiving affects their emotional, financial and work lives, as well as their families.
It seemed as if it would be a perfectly ordinary occasion, that hot August day in 1959. Three generations of a large Oklahoma family gathered at a studio in nearby Perryton, Tex., to have a photo taken of the elders, 14 siblings ranging in age from 29 to 52. Afterward, everyone went to a nearby park for a picnic.
Dementia is thought of as a scourge of the developed world, with its aging population, but it actually may occur at an even higher rate in developing countries, or so, at least, report researchers led by Martin Prince at King's College London U.K., in the May 23 Lancet. A shift in these countries' populations toward aging, combined with low education and undercounting, is blamed for the finding.
The Food and Drug Administration (FDA) approved on April 10th a brain imaging method for individuals who are being evaluated for Alzheimer's Disease (AD) or other causes of progressive cognitive impairment. The new method uses a drug called Amyvid (also known as Florbetapir or AV-45) along with Positron Emission Tomography (PET). MGH ADRC researchers were co-investigators for the clinical trial in which Amyvid was developed and have used this and other, similar PET methods for research purposes since 2005.
Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.
The Food and Drug Administration (FDA) has approved Amyvid (florbetapir F18 injection), Avid Pharmaceuticals/Eli Lilly and Company's positron emission tomography (PET) tracer, for A-Beta plaque imaging in cognitively impaired patients being clinically evaluated for Alzheimer's disease. The compound will be available for use in June, with the aim of helping researchers rule out - not diagnose - the disease.
Worldwide, nearly 35.6 million people live with dementia. This number is expected to double by 2030 (65.7 million) and more than triple by 2050 (115.4 million). Dementia affects people in all countries, with more than half (58%) living in low- and middle-income countries. BY 2050, this is likely to rise to more than 70%.
Treating and caring for people with dementia currently costs the world more than US$604 billion per year. This includes the cost of providing health and social care as well as the reduction or loss of income of people with dementia and their caregivers.
Under normal circumstances, the tau protein is a hard-working participant in memory and normal brain functioning. But as is becoming increasingly evident, in Alzheimer's disease and other neurodegenerative diseases, tau not only ceases to play a productive role in brain health, but actually undergoes a Jekyll-and-Hyde transformation to become a misshapen villain that destroys brain cells.
Two independent laboratories -- one at Columbia University; the other, at Harvard Medical School -- have devised a clever set of experiments to prove that the pathology that leads to tangle formation in Alzheimer disease (AD) spreads across the brain from neuron to neuron rather than selectively hitting vulnerable regions at different time points over the course of the disease.
The finding answers a pivotal question as to how AD progresses, and could open the door to novel treatments that could stop the disease from spreading and damaging key cognitive circuits.
Repression of certain gene activity in the brain appears to be an early event affecting people with Alzheimer's disease, a new study found. In mouse models of Alzheimer's disease, this blockage and its effet on memory were treatable.
Alzheimer's disease is the most common cause of dementia in older adults. It affects as many as 5.1 million Americans. A hallmark of the disease is the accumulation of a toxic protein fragment called beta-amyloid in brain nerve cells (neurons). Preventing the cognitive problems that result has been a major medical challenge.
