Brain tissue loss in people with Alzheimer’s disease and mild cognitive impairment
People with Alzheimer's disease exhibit striking structural changes in the caudate nucleus, a brain structure typically associated with movement disorders such as Parkinson's disease, a new study has found.

Brain scans may help guide career choice
General aptitude tests and specific mental ability tests are important tools for vocational guidance. Researchers are now asking whether performance on such tests is based on differences in brain structure, and if so, can brain scans be helpful in choosing a career? In a first step, researchers have investigated how well eight tests used in vocational guidance correlate to gray matter in areas th

Reduced brain gray matter concentration found in patients with severe obstructive sleep apnea
In a study of 36 newly diagnosed men with severe obstructive sleep apnea and 31 healthy controls, significant gray matter concentration deficits were found in multiple brain areas of men with OSA, including limbic structures, prefrontal cortices and the cerebellum. These changes in brain structure may be related to problems such as memory impairment and executive dysfunction that are observed in

Alzheimer’s disease imaged long before symptoms appear
Researchers were able to predict a brain's progression to Alzheimer's by measuring subtle changes in brain structure over time, changes that occur long before the symptoms of AD can be seen. With an earlier diagnosis, earlier intervention would be possible.

Uniform method to interpret autism spectrum disorders
The main criterion defining autism spectrum disorders is difficulty in emotional-social behavior. Nevertheless, many people with ASD have some difficulties in three other domains -- memory, perception and motor behavior. In a new theoretical model, one researcher recommends a uniform way to think about these four types of difficulties, which she believes are linked by a common brain structure/bra

Colombian Guerrillas Help Scientists Locate Literacy In The Brain
A unique study of former guerrillas in Colombia has helped scientists redefine their understanding of the key regions of the brain involved in literacy. The study has enabled the researchers to see how brain structure changed after learning to read.

Brain Region Responsible For Our Sense Of Personal Space Discovered By Caltech Neuroscientists
In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space. The discovery, described in the August 30 issue of the journal Nature Neuroscience, could offer insight into autism and other disorders where social distance i

Common Variation In Gene Linked To Structural Changes In The Brain
An international group of researchers is the first to show that common variations in a gene previously shown to be associated with Retts Syndrome, autism, and mental retardation are associated with differences in brain structure in both healthy individuals and patients with neurological and psychiatric disorders. Their findings will be published in the early online edition of the Proceedings of t
