Research conducted with rats shows
that one possible cause of autism is oxygen deprivation during birth.
Fabrizio Strata, a neuroscience
researcher at the University of California, San Francisco who is
co-author of the study shows a potential non-genetic occurrence of
autism. There is no data study of humans in this study, and if the
oxygen deprivation is the cause of the autism, it does not lead to any
easy treatment.
The study was conducted by depriving
oxygen level in rat pups for as long as 10 – 12 minutes during birth by
increasing the nitrogen in the air. As the rats grew older they had
symptoms similar to those found in autistic children. The rats that
were deprived took longer to respond to sounds and the region of the
brain that handles sound were disrupted.
Distinctive behaviors of
autistic children are difficulty with social interaction, have problems
with verbal and nonverbal communication, they have narrow obsessive
interests and also will do repetitive activities.
The thought behind this study is the
potential of oxygen deprivation during the birthing process caused by a
twisted umbilical cord for instance. The lack of oxygen could
potentially be one of the causes of autism, but the study was not able
to conclude that for certain. Possible further research data on births
of autistic children would help to define the potential of autism caused
during the birthing process.
