Brain Size May Predict Risk For Early Alzheimer’s Disease

New research suggests that, in people who do not currently have memory problems, those with smaller regions of the brain’s cortex may be more likely to develop symptoms consistent with very early Alzheimer’s disease. The study is published in the December 21, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.

Cognitive Decline In Patients With Parkinson Disease Associated With Certain Patterns Of Brain Volume Decreases

Patients with Parkinson disease-related dementia appear to have increased brain atrophy in the hippocampal, temporal and parietal lobes and decreased prefrontal cortex volume compared to patients with Parkinson disease without dementia, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archivesjournals. The study was conducted by Daniel Weintraub, M.D., […]

Childhood Maltreatment Associated With Cerebral Gray Matter Reductions In Adolescents

od maltreatment is associated with reductions in cerebral gray matter volume, and even if adolescents reporting exposure to maltreatment do not have symptoms that meet full criteria for psychiatric disorders, they may have cerebral gray matter changes that place them at risk for behavioral difficulties, according to a report in the December issue of Archives […]

Boys With Regressive Autism, But Not Early Onset Autism, Have Larger Brains Than Age-Matched Healthy Counterparts

In the largest study of brain development in preschoolers with autism to date, a study by UC Davis MIND Institute researchers has found that 3-year-old boys with regressive autism, but not early onset autism, have larger brains than their healthy counterparts. The study is published online today in the Proceedings of the National Academy of […]

Brain Imaging Helps To Explain How The Brain Benefits From Meditation

Experienced meditators seem to be able switch off areas of the brain associated with daydreaming, as well as psychiatric disorders, such as autism and schizophrenia, according to a new brain imaging study by Yale researchers. Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. […]

New MRI Technique To Diagnose Or Rule Out Alzheimer’s Disease

On the quest for safe, reliable and accessible tools to accurately diagnose Alzheimer’s disease, researchers from the Perelman School of Medicine at the University of Pennsylvania found a new way of diagnosing and tracking Alzheimer’s disease, using an innovative magnetic resonance imaging (MRI) technique called Arterial spin labeling (ASL) to measure changes in brain function. […]

Computer Analysis Of Brain Scans May Predict Outcome Of Psychotic Episodes

Computer analysis of brain scans could help predict how severe the future illness course of a patient with psychosis will be, according to research funded by the Medical Research Council and the Wellcome Trust. The findings could allow doctors to make more accurate decisions about how best to treat patients. Psychosis is a condition that […]
