Older adults with hearing loss appear more likely to develop dementia, and their risk increases as hearing loss becomes more severe, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals. By the year 2050, an estimated 100 million people or nearly one in 85 individuals worldwide will be affected by dementia, according to background information in the article. Interventions that could delay the onset of dementia by even one year could lead to a...

Older adults without dementia and with lower levels in plasma of the biomarkers beta-amyloid 42/40 (protein fragments) had an increased rate of cognitive decline over a period of 9 years, according to a study in the January 19 issue of JAMA. The researchers also found that this relationship was stronger among individuals with less education and lower levels of literacy. An estimated 36 million people currently have dementia, with the prevalence expected to double every 20 years, according to...

Watching the brain's "autopilot" network in real time may help determine the onset of cognitive decline and potentially aid in making an early diagnosis of Alzheimer's disease, according to researchers at Duke University Medical Center. While traditional MRI and imaging studies conducted in Alzheimer's disease have focused on the anatomy and function of individual regions of the brain, the Duke team conducted the first study to test how the integrity of an entire brain network relates to...

Participants included individuals who carry a high-risk gene Physical activity promotes changes in the brain that may protect high-risk individuals against cognitive decline, including development of Alzheimer's disease, according to a new study done at the University of Wisconsin-Milwaukee (UWM). J. Carson Smith, an assistant professor of health sciences, included in the study both people who carry a high-risk gene for Alzheimer's disease, and other healthy older adults without the gene....

No drug interventions are this dramatic, say investigators A Canadian science team has found more dramatic evidence that speaking two languages can help delay the onset of Alzheimer's symptoms by as much as five years. The latest study, led by Baycrest's Rotman Research Institute, examined the clinical records of more than 200 patients diagnosed with probable Alzheimer's disease and found that those who have spoken two or more languages consistently over many years experienced a delay in the...

Even healthy, active older people experience subtle deficits in mental functioning Older people who are leading active, healthy lifestyles often have silent vascular disease that can be seen on brain scans that affect their ability to think, according to a new study led by UC Davis researchers and published online today in the Archives of Neurology, one of the JAMA Archives journals. "This study shows that silent vascular disease is really common as we get older and it influences our thinking...

(Ivanhoe Newswire) -- Is vascular disease unavoidable? This study shows that even older people who lead active, healthy lifestyles usually have silent vascular disease that can be seen on a brain scan. The disease affects their ability to think. "This study shows that silent vascular disease is really common as we get older and it influences our thinking abilities," Charles DeCarli, professor of neurology in the School of Medicine at UC Davis and director of the UC Davis Alzheimer's Disease...

A new study shows that a mentally active lifestyle may protect against the memory and learning problems that often occur in multiple sclerosis (MS). The study is published in the June 15, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology. "Many people with MS struggle with learning and memory problems. This study shows that a mentally active lifestyle might reduce the harmful effects of brain damage on learning and memory. That is,...

No differences in decline among African American and white patients People with Alzheimer's disease experience a rate of cognitive decline four times greater than those with no cognitive impairment according to a new study by researchers at Rush University Medical Center in Chicago. The results of the study, which is only the second population-based study to quantify the rate of cognitive decline in Alzheimer's disease, are published in the March 23, 2010 issue of the journal Neurology, the...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
