Scientists from Harvard University have discovered the probable cause of autism. They were the first ones to connect a specific neurotransmitter in the human brain with the incidence of the disease. Due to this observation the spectrum of knowledge about autism, and thus the diagnostic and therapeutical possibilities regarding autism, would widen. The previous reports described the role of GABA signalling in the pathogenesis of the disease on animal models. The team of scientists under the lead of Caroline Robertson from Harvard Society of Fellows were the first ones to prove its vital role in the development of the disorder in people.
The researchers report that people suffering from autism spectrum (ASD) have no natural sniffling habit in response to pleasant stimuli such as perfumes. Children with autism react with sniffing in the same way regardless of whether the odor is pleasant or not. The study results were published on July 2 in the pages of The Cell Press Current Biology.

Autism is a neurodevelopmental disorder. It is the third most common developmental disability – it is even more common than Down’s Syndrome. It typically appears during the first three years of a child’s life and is characterized by social impairments, communication difficulties, showing no affection and stereotyped patterns of behavior. At the beginning of XXI century most recent reviews showed that the prevalence of autism is about 10 and 40 per 10,000 and it is four to five times more common among boys than girls.
Scientists from the University of California, San Diego Health Sciences and Allen Institute for Brain Science discovered that six layered structure of cortex is focally disrupted in autistic patients. Their results suggest that autism begins long before birth whereas environmental factors influence further disease development. Read full text »

Autism spectrum disorders (ASD) is used in medical terminology to describe developmental disorders which have characteristic symptoms: poor social interaction, communication difficulties and repetitive behaviours. Autism spectrum disorders include autism, Asperger syndrome, and pervasive developmental disorder not otherwise specified (PDD-NOS). It is estimated that the disease affects 1 per 1000 people and is four times more common among males than females. Currently, the disease is incurable and in order to mitigate its symptoms pharmacological and psychological treatment can be used.
For many years parents have been blamed for their ADHD children outrageous behavior. The disease had been thought to be of pure social origin and the parents have been living under pressure of their prejudiced neighbours and collegues.The recent UK study has been a great breakthrough and it predicts a big change in the approach to the issue.
