Recording people belting out an old Motown tune and then asking them to listen to their own singing without the accompanying music seems like an unusually cruel form of punishment. But for a team of scientists at the University of California, San Francisco and University of California, Berkeley, this exact Karaoke experiment has revealed what part of the brain is essential for embarrassment.
Using MRI, researchers may be able to predict which adults with mild cognitive impairment are more likely to progress to Alzheimer’s disease, according to the results of a study published online and in the June issue of Radiology. Mild cognitive impairment (MCI) is an intermediate stage between the decline in mental abilities that occurs in normal aging and the more pronounced deterioration associated with dementia, a group of brain disorders that includes Alzheimer’s disease (AD).
Results from a new study contribute to growing evidence that if one of your parents has Alzheimer’s disease, the chances of inheriting it from your mother are higher than from your father. The study is published in the March 1, 2011, print issue of Neurology, the medical journal of the American Academy of Neurology.
Nearly 16 million Americans will be diagnosed with Alzheimer’s disease or another type of dementia by 2050, according to the Alzheimer’s Association. Symptoms include mood and behavior changes, disorientation, memory loss, and difficulty walking and speaking. The effects of anti-dementia drugs on patients’ emotions and behaviors are inconsistent. Now, University of Missouri researchers have found that participation in TimeSlips, a drug-free, creative storytelling intervention, improves communication skills and positive affect in persons with dementia.
Quietmind Foundation, a not-for-profit clinical research, consultation, and training organization at the forefront of noninvasive, drug-free treatments for dementia and other neurocognitive impairments, is launching the first-ever clinical trial of its type to assess a new approach to improve mental functioning for sufferers of early-stage dementia. The researchers currently seek to enlist potential participants for this study. Relevant contact information is included at the end of this report for those who want to inquire about possible participation in this clinical trial.
A warning issued by the Food and Drug Administration regarding the use of atypical antipsychotics for the treatment of dementia was associated with a significant decline in the use of these medications for treating dementia symptoms in elderly patients, according to a report in the February issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Researchers from the University of Gothenburg and Sahlgrenska University Hospital are the first in the world to show that an operation can help patients with dementia caused by white matter changes and hydrocephalus (see definition below for more information). Presented in the American Journal of Neurosurgery, the results are based on the world’s first study to demonstrate the effects of a shunt operation using a placebo control.
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. The results are published in Neurology, the medical journal of the American Academy of Neurology.
