The brain is essential to growth and development in humans. During the critical period of development, how we experience the world plays a role in our brain development. In recent years, autism spectrum disorder (ASD) has become prevalent among disorders that affect brain development. Due to advancements in technology, the world is able to understand how important brain research is to the early detection of autism.
Leo Kanner is the first person to formally identified autism. In 1943, Kanner labeled autism as “autistic disturbance of affective contact”. Initially, there was a lot of confusion concerning Kanner’s description of autism because it was closely related to the characterization of other mental disorders (Blancher and Christensen 2011). In order to effectively study and understand the causes of disruption in the brain, researchers have done experiments to explore the differences between a normal brain and an autistic brain. Researchers have found that structural differences, such as size and composition, can have a significant impact on how the autistic brain processes information. Therefore, there is a variation between a normal person and one with autism. Structural differences cause an autistic person to have impaired social interaction and difficulty with communication, both verbal and nonverbal.
Early signs of ASD may appear in the reflexive/spontaneous phase (third fetal month to the first year of life). Autistic infants tend to avoid interactions with other humans. They tend to avoid eye contact and react adversely to touch. Additionally, autistic children do not develop as fast as normal children. A normal child will grasp an object or react to various body gestures given by others. On ...

It is widely accepted that it is caused by abnormalities in the brain structure or function. There is evidence from neuropathological studies that autism has its origins in abnormal brain development early in prenatal life which continues postnatally, showing acceleration in brain growth measured by head circumference (Zwaigenbaum, L., Bryson, S., Rogers, T., Roberts, W., Brian, J., & Szatmari, P., 2005). The disorder also seems to have a genetic basis, although researchers have yet to find the specific genes that link to the onset of autism. There could be a cluster of genes that have somehow interfered with normal brain development and function. Studies show that twins of children with autism were more likely to be autistic themselves than the regular population, demonstrating there is a heredity lin... ... middle of paper ... ..., Tager- Flusberg, H.,& Lainhart, J.

In one study, parenting styles between parents with autistic children and parents with non-autistic children differed greatly in responses (Strid, 2013). This conclusion leads to the fact that families who have autistic children react differently to certain scenarios. Having an autistic child within the family can lead to several different scenarios involving the child, such as having difficulty maintaining order in the household or arguments concerning the welfare of the child. However, these circumstances can also lead to the child’s family becoming much more understanding towards people with autism (Jahromi, 2012).
