Origins of autism: Abnormalities in sensory processing at six months
Quote:
Scientists used a type of magnetic resonance imaging (MRI), known as diffusion weighted imaging, to measure the brain connectivity in 260 infants at the ages of 6 and 12 months, who had either high or low risks of autism. The lengths and strengths of the connections between brain regions was used to estimate the network efficiency, a measure of how well each region is connected to other regions. A previous study with 24-month-old children found that network efficiency in autistic children was lower in regions of the brain involved in language and other behaviours related to autism. The goal of this new study was to establish how early these abnormalities occur.
Lead author John Lewis, a researcher at the Montreal Neurological Institute and Hospital of McGill University and the Ludmer Centre for Bioinformatics and Mental Health, found network inefficiencies had already been established in six-month-old infants who went on to be diagnosed with autism. Inefficiencies in the six-month-olds appeared in the auditory cortex. He also found the extent of the inefficiency at six months of age was positively related to the severity of autistic symptoms at 24 months. As the children aged, areas involved in processing of vision and touch, as well as a larger set of areas involved in sound and language, also showed such a relation between inefficiency and symptom severity.
Identifying the earliest signs of autism is important because it may allow for diagnosis before behavioural changes appear, leading to earlier intervention and better prospects for a positive outcome.
Bolding mine.
The bolded part kind of confirms what I have been trying to say. The constant push for finding autism earlier and earlier is to intercept the combination of genetics and environment wiring the brian autistic. That is the "positive outcome" desired. No need to find a cure if they can prevent autism from happening in the first place. They can not say that directly for a number of reasons. What intervention is used to intercept the autism is not their job although I am pretty sure it will be Applied Behavoiral Analysis. It would be very premature for them to make that direct of a statement. These findings need to be replicated. Many other areas of the brain need to be studied, interventions might not or only patially "work"
