Different ingredients in marijuana appear to affect regions of the brain differently during brain processing functions involving responses to certain visual stimuli and tasks, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. Sagnik Bhattacharyya, M.B.B.S., M.D., Ph.D, at the Institute of Psychiatry, King’s College in […]

Maltreated Children Show Same Pattern Of Brain Activity As Combat Soldiers
Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, new research has shown. In the first functional MRI brain scan study to investigate the impact of physical abuse and domestic violence on children, scientists at UCL in collaboration with the Anna Freud Centre, found that […]
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 […]
3D-TV Does Not Appear To Increase The Risk Of Seizures In Susceptible Children
Certain visual patterns and flashing images can provoke seizures in susceptible individuals, particularly among children and adolescents. Some media reports on the recent introduction of 3D-television sets suggest that this new technology may cause seizures in some viewers. Children who have epilepsy are somewhat more vulnerable to the provocative stimuli than their peers. But there […]
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 […]
Frequent “Heading” In Soccer Can Lead To Brain Injury And Cognitive Impairment
Using advanced imaging techniques and cognitive tests, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center, the University Hospital for Einstein, have shown that repeatedly heading a soccer ball increases the risk for brain injury and cognitive impairment. The imaging portion of the findings was presented today at the annual […]
