Psychiatry Bibles Makeover

Psychiatry Bibles MakeoverThe American Psychiatric Association has released the fifth edition of its Diagnostic and Statistical Manual, known as DSM-5. At a cost of $25 million. the revision happens only once in a generation and comes after nearly two decades of debate, deliberation and change in clinical practice.

The manual is produced primarily as a diagnostic tool for American psychiatrists, helping them to diagnose and treat their patients – and bill them accordingly. The revision is based on new insights from research since the last version of the manual was published in 1990.

Hoarding, gambling and marijuana withdrawal are among the newly expanded disorders contained in the fifth revision of the 947-page reference book. However, many healthcare professionals argue that it’s time to start from scratch and create a new system for diagnosing mental illness based on biological data. Others say that the manual turns too many aspects of normal life, such as grief, into medical conditions :: Read the full article »»»»


New Research Predicts Autism Much Earlier

Posted: January 29th, 2012 | Author: | Filed under: Cankler Science News | Tags: , , , , | Comments Off on New Research Predicts Autism Much Earlier

New Research Predict Autism EarlierAutism, a disorder of neural development characterized by impaired social interaction, restricted and repetitive behavior. The signs of Autism all begin before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not yet well understood.

Signs of ASD are diagnosed in the first three years of a child’s life, generally between the second and third year, the signs develop gradually, in some cases however, autistic children first develop more normally, and then regress.

New research has shown that children who develop autism may show signs of different brain responses in their first year of life, researchers say the study may in the future help doctors diagnose the disorder much earlier :: Read the full article »»»»


Extra Brain Cells May Explain Autism

A new study suggests that Autism starts in the womb, researchers have found a remarkable 67 per cent increase in the total number of brain cells in the prefrontal cortex of new born babies with ASD.

Extra Brain Cells May Explain AutismChildren with autism appear to have too many cells in a key area of the brain needed for communication and emotional development, say US researchers. Their findings help explain why young children with autism often develop brains that are larger or heavier than normal. Dr Eric Courchesne says the finding of excess brain cells in the prefrontal cortex explains brain overgrowth in autism, and hints at why brain function in this area is disrupted. Courchesne, of the University of California San Diego Autism Center of Excellence, and colleagues, have also found dozens of genes that may raise the risk of autism. But genetic causes only explain 10 per cent to 20 per cent of cases, and recent studies have pointed to environmental factors, possibly in the womb, as a potential trigger. The team found excess brain cells in each child with autism they studied, says Courchesne. And the brains of the autistic children also weighed more than those of typically developing children of the same age.

Researchers searching for an early indicator of autism say they’ve discovered a promising possibility, an impairment in the ability of the brain’s right and left hemispheres to communicate with each other. The researchers did brain imaging scans – fMRIs – on 29 sleeping toddlers with autism, 30 typically developing kids and 13 children with significant language delays, but not autism. All were between 1 and 4 years old. The scans showed that the language areas of the left and right hemispheres of the autistic toddlers’ brains were less “in sync” than the hemispheres of the typical kids and the children with other language delays. The weaker the synchronization, the more severe the autistic child’s communication difficulties :: Read the full article »»»»
