The Causes Of Autism Spectrum Disorder

Several environmental factors have also been suspected of attributing to the cause of autism such as: exposure to infectious disease, heavy metals, phthalates and phenols, pesticides, alcohol, illicit drugs, advanced maternal age, maternal bleeding during pregnancy, maternal medications used during pregnancy and maternal stress (Glasson et al., 2004). The research conducted by Glasson et al., (2004) shows that individuals who were later diagnosed with autism were more likely to have experienced obstetric difficulties during pregnancy, labor, delivery and neonatal period. Advanced maternal age was the strongest finding in that study.

“Independent of the genome screens, evidence suggests that the region on chromosome 15q11-13 contains a gene or genes relevant to Autism.” (Dr. David Pauls 2003). Basically, there are suggestions that the chromosome 15q11-13 is somehow mutated, deleted, or duplicated, causing this disorder to transpire. In addition to genetics, environmental factors can influence Autism; though they are not greatly supported ideas, they can’t be entirely ruled out. In the UK there have been reports of the measles vaccine having a part in causing this disorder. (Dr. David Pauls 2003). Newer studies have even shown that prenatal care before a woman even conceives reduces the risk extensively. “Woman who did not take a daily multivitamin in the three months before conception and during the first month of pregnancy were almost twice as likely to give birth to a child with ASD as a woman who had taken a daily multivitamin.” (The Harvard Mental Health Letter 2011). Multivitamins contain a lot of helpful vitamins to maintain a healthy pregnancy, but researchers suggest that the folic acid is the most significant influence that reduces the risk of a child born with ASD. (The Harvard Mental Health Letter

Autism Spectrum Disorder (ASD) is a group of conditions of the brain development. (Vries, 2015). The main characteristic of individuals with Autism Spectrum Disorder (ASD), is that they have difficulties to adapt and interact with other people. Also, individuals with Autism have problems with their development of verbal and nonverbal communication. They show a repetitive behavior that is usually recognized during the first three years of life. Approximately one of sixty eight children are affected with Autism Spectrum Disorder (ASD) in the United States. (Vries, 2015).

Autism Spectrum Disorder is a name that is used for a group of developmental disorders. Children with Autism have great difficulty with bonding emotionally with others, they find it hard to make eye contact with others, communicate their feelings and express themselves to the people who are closet to them. Autism effects the brain which inhibits these children to interact, communicate, and concentrate. A child with Autism will display behavior such as, repetitive behavior, rocking, flapping hands, repetition of words, and will want to always arrange objects.

Autism is one of the most common disorders among children in the United States. Autism affects 1 in 68 children (Center for Disease Control, 2014). By comparison, this is more children than are affected by diabetes, AIDS, cancer, cerebral palsy, cystic fibrosis, muscular dystrophy or Down syndrome – combined (Autism Speaks, 2012). Boys are four times more likely to have autism than girls. This disorder typically appears during the first three years of life.

Autism is a spectrum disorder that refers to a range of conditions characterized by challenges with social skill impairment, repetitive behaviors, speech and nonverbal communication, as well as unique strengths and differences.

Autism is described as a neurodevelopmental disorder that inhibits characteristics like impaired social interaction, difficulties in verbal and non-verbal communication, cognitive disorders and repetitive behavior.

Per the American Speech-Language-Hearing Association (ASHA), autism spectrum disorder or autism is defined as a complex neurodevelopmental disorder characterized by deficits in social communication and social interaction. It is characterized by difficulty communicating, forming relationships with people, using language correctly and comprehending abstract concepts. It has the presence of restricted, repetitive behaviors. Many challenges exist in the use of

There has been great discussion over the recent increase in Autism over the decades with no full explanation as to why. Scientists believe that both genetics and environment may play a role in Autism Spectrum Disorder. Studies suggest that ASD could be a result of disturbances in normal brain growth very early in development. These disruptions

Autism spectrum disorder is a developmental disability that can cause significant behavioral, social, and communication challenges (CDC, 2015).

What is Autism Spectrum Disorder? Autism is a neurodevelopment mental diagnosis presented from early childhood. The expression spectrum is viewed by the level of functioning and skills that’s occurs in individuals with this diagnosis. (www.autismspeaks.org). Those who are high on the spectrum can sometimes function on their own with little assistance and there are the low functioning who require more assistance or hands on. Autism is categorized by challenges with socialization, repetitive conducts of behavior, impaired speech and verbal and nonverbal communication. Autism is characterized by numerous things such as difficulty in communicating and forming relationships with other people.

Autism is a spectrum of neurodevelopmental disorders characterized by a decrease in social interaction and communication. People with autism have limited behavior (not varied) and repetitive.

Just as there is no duplicate case of autism, there is no one cause. Alternatively, there is a list of causes. Some of the most common include genetic mutation and predisposition as well as environmental factors. Some research shows that women can reduce the chance of their children being autistic by increasing folic acid intake before and following conception. Other research shows that “advanced paternal age can affect the child’s risk” of being

Autism is a disorder characterized by significant problems in communication and social functioning. Autism is actually called Autism Spectrum Disorder and encompasses a broad range disabilities such as Asperger syndrome, Rett’s Syndrome, and Pervavasive Development Disorder (Dunlap & Fox, n.d.). There are also varying degrees of the disorder from low-functioning (no communication and no social interaction) to

According to Shangraw (2012), there is no concrete etiology of autism because it is not diagnosed by its cause but on observed behaviors. The Autism-Society (n.d.) stated that a possibility for the cause of autism is the abnormalities in the brain structure or function. In an MRI research study by Piven et al. (1995), they found that an individual with autism spectrum disorder had a higher total brain volume and tissue compared to a person who is not on the autism spectrum disorder. Genetic problems and environmental factors can be a cause of autism spectrum disorder, according to the Mayo Clinic (2014). In genetic problems such as fragile X syndrome or Rett Syndrome, it can be associated with autism spectrum disorder. There is ongoing research regarding environmental factors and exploring ideas such as viral infections, pregnancy complications, and / or air pollutants to determine if they are active factors of autism spectrum disorder.
