In the article “Autism: Cause
Factors, Early Diagnosis, and Therapies” Shreya Bhat, U. Rajendra Acharya, Hojjat
Adeli, G. Muralidhar Bairy, and Amir Adeli discuss the different types of
autism and several possible causes of autism. Out of all of the disabilities,
autism is among the fastest growing, and according to the CDC, 1 in 68 are born
with autism (Bhat, Acharya, Adeli, Bairy, & Adeli, 2014). Autism cannot be
cured. However, there are many things that can be done to help those who have
autism. Bhat, Acharya, Adeli, Bairy, and Adeli (2014) discussed the three main
types of autism as autistic disorder (or classic autism), Asperger’s syndrome,
and pervasive developmental disorder.

have been many different studies and lots of research done to try to figure out
the causes of autism. The authors also gave five possible causes of autism in
the article: “genetic/chromosomal variations, over-connectivity between neural
assemblies, under-connectivity of functional brain regions, environmental factors,
and impairment in white matter connectivity and gray matter diffusivity” (Bhat,
Acharya, Adeli, Bairy, & Adeli, 2014, p. 4). Because not every case of
autism is diagnosed at the same time or age, it can be difficult to know all of
the causes of autism.

Autism spectrum disorder (ASD) is
defined as “a complex neurobiological disorder characterized by neurobiological
and behavioral deficits” (Bhat, Acharya, Adeli, Bairy, & Adeli, 2014, p.

1). CHD8 or “chromodomain helicase DNA binding protein 8” is a mutated gene
that has been found to be associated with autism (Bhat, Acharya, Adeli, Bairy, &
Adeli, 2014, p. 4). GABA is a gamma-aminobutyric acid and elevated levels of
this acid is thought to be a cause of autism. In individuals who have ASD, the neural
connectivity is increased, causing various musical abilities to be retained. These
variations are classified as symptoms of autism. Virtual reality is used to
help with early diagnoses of autism through helping to monitor eye gazes of


            One can see that, through this study
that there is constant research being done for people to learn more about the
causes of autism and what can be done to help individuals with autism live
their lives to their full potential. Many therapies and treatments have been
discovered to help these individuals. The authors agree that because autism is
a neurobiological disorder, it may be difficult to pinpoint one specific cause.

However, because of the modern technologies, it is now easier to detect at an
early time in an individual’s life.
