Person's inability to understand sarcasm and lies can be a warning sign of dementia

By asking a group of older adults to analyze videos of other people conversing -- some talking truthfully, some insincerely -- a group of scientists at the University of California, San Francisco has determined which areas of the brain govern a person's ability to detect sarcasm and lies.

Neural dysfunction underlying impulsive choice increases with AD severity: Study

Researchers already know that alcohol dependence is strongly associated with impaired impulse control or, more precisely, the inability to choose large, delayed rewards rather than smaller but more immediate rewards.

Study finds association between C-reactive protein and memory decline

High levels of a protein associated with chronic, low-grade inflammation in the brain correlate with aspects of memory decline in otherwise cognitively normal older adults, according to a study led by scientists at the University of California, San Francisco.

Brain starts shrinking in Alzheimer’s disease a decade earlier: Study

According to American researchers, brain scans of healthy people showed signs that the brain was shrinking in Alzheimer's-affected areas nearly a decade before the disease was diagnosed. This comes in the latest issue of the journal Neurology and it may offer a new way to detect the disease early, an advance that could help in the development of effective treatments for Alzheimer's, a brain-wasting disease that affects up to 26 million people globally.

New research: MRI can help detect early stage Alzheimer's disease

New research suggests that magnetic resonance imaging could help detect Alzheimer's disease at an early stage, before irreversible damage has occurred, according to a new study published online and in the June print edition of Radiology.

Alcohol binge-drinking in teen years could affect decision-making and related behaviors as adults

Adolescents represent the majority of people who binge drink. This may come as a surprise to some, but recent surveys indicate that episodes of heavy alcohol drinking within the previous two weeks are reported by 12 percent of 8th graders, 22 percent of 10th graders, 28 percent of 12th grade seniors and 44 percent of college students.

Food addicts appear to have high neural activity in brain

Persons with an addictive-like eating behavior appear to have greater neural activity in certain regions of the brain similar to substance dependence, including elevated activation in reward circuitry in response to food cues, according to a report posted online today that will appear in the August print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Scientists to develop new techniques for autism detection and treatment

To parents, learning that a child has been diagnosed with autism can be overwhelming. Children with the disorder can seem trapped in a world of their own, without friends or even a conception of friendship. Many prefer to play alone. Some lose the ability to speak more than a few words.

First MR images to show complete borders in human cerebral cortex

Understanding functional properties of the brain’s structural units is one of the main aims of brain research. Until now only fragmentary borders of brain areas could be identified in vivo since the resolution in MR images was not high enough.

Important updates on spondyloarthritis highlighted at 2010 SPARTAN meeting

Spondyloarthritis is a group of inflammatory conditions causing spine and joint pain and deformity, mostly in young men. Important updates on the epidemiology, diagnosis, and treatment of SpA are presented in the April issue of The American Journal of the Medical Sciences, official journal of the Southern Society for Clinical Investigation.

Amyloid plaques in normal older individuals may be early signs of Alzheimer's

Researchers using two brain-imaging technologies have found that apparently normal older individuals with brain deposits of amyloid beta - the primary constituent of the plaques found in the brains of Alzheimer's disease patients - also had changes in brain structure similar to those seen in Alzheimer's patients.
