BEIJING, Nov. 15 (Xinhuanet) -- John Hopkins University
School of Medicine launched a study of the cause of autism and had made a step
forward.
A recent study
of brain tissue taken from affected patients has revealed that an immune
system reaction leading to swelling of the brain could lie behind the condition.
If confirmed, doctors believe they could develop a test for autism and possibly
a treatment to prevent it.
But scientists cannot
diagnose the condition at present until the first signs of problems in
communication appear, normally in the second year of life.
"These findings open new possibilities for
understanding the dynamic changes that occur in the brain of autistic patients
during childhood and adulthood. Although they may lend themselves to the
development of new medical treatments for autism, much more research would be
needed to establish the validity of this approach" Professor Carlos Pardo-Villamizar of John Hopkins University
School of Medicine, who led the study, was quoted by BBC News as saying.
Autism is an annoying brain
disorder that leaves sufferers with difficulties in social interaction. The
disease has been increasing rapidly in the last decade at a faster rate than
would be expected for a genetic disorder, suggesting some environmental
cause. Enditem
