Autism experts are calling for changes in diagnostic testing, saying the current approach is failing to identify the true number of females with the disorder.
They say a massive imbalance in the number of autism diagnoses between the sexes could be attributed to more subtle symptoms in females that are either dismissed by clinicians, or undetected by current testing, which focuses on signs associated with male behaviour.
The challenge in diagnosing girls with autism is a focus of Dr Ernsperger, who is speaking at a conference in Melbourne.
She believes the diagnostic questionnaires doctors use for autism focus mainly on the male characteristics of the disorder and are yet to be adapted for girls :: Read the full article »»»»

Autism, 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 »»»»

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.
Children 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 »»»»

Ice baths are not as effective as an active warm down in soothing athletes’ muscles, Queensland researchers have found.
The researchers have thrown cold water on the use of ice baths to soothe the overworked muscles of athletes.
According to conventional thinking, ice baths reduce inflammation and damage. however a joint study by the University of Queensland and Queensland University of Technology has found an active warm down is more effective in building muscle mass and strength.
The University of Queensland’s School of Human Movement’s Dr Llion Roberts tracked the progress of 21 men who did strength training two days a week for three months.
Half of them did an active warm down and the rest had a 10 minute ice bath at 10 degrees :: Read the full article »»»»

The scientific community is stunned by research which backs an Australian Aboriginal legend on how coastal palm trees got to Central Australia. Tasmanian ecologist Professor David Bowman did DNA tests on palm seeds from the outback, and his conclusion is startling :: Read the full article »»»»
