Characteristics and causal theories of ASD

Autism Spectrum Disorder (ASP) is a wide range of disorders that affect the neurological development in children. Though there are many conditions that exhibit the development of the brain in children there is consensus that ASP largely include, pervasive development disorder, autistic disorder, asperger disorder and childhood disintegrative disorder. These conditions greatly inhibit in different ways the sociological and mental development of children through inadequate communication development and typically stereotyped or, repetitive behaviors and interests.

The characteristics of ASP are as varied as the conditions themselves. However, some characteristics cut across the board and children suffering from any ASP condition are more likely to exhibit them.

Individuals with ASD tend to have both verbal and non verbal communication challenges. While others may develop their language skills others have difficulties with making even a single word. For the ones with good speech, they might only understand the literal meaning and not the social meaning. Autism is also characterized by repetitive behavior, difficulties in learning, outstanding performance in some areas, inability to maintain eye contact, trouble controlling excitement and emotions and being uneasy in social places and events. The degree of ASD may vary from one individual to another but as indicated earlier, it mainly affects their social, behavioral and communication abilities. While the causes of ASD are still not well known, researchers have identified that genes and environmental factors play a major role. According to studies Boys are more likely to develop this condition as compared to girls. Various research findings have tried to consolidate different ASD characteristics to try and explain the causes.

Genetics is the most commonly cited cause of autism spectrum disorders (ASD). Some researchers have also identified a somewhat clear link between administration of some vaccines such as thimerosal and occurrence of autism spectrum disorder. According to Worth, genetic factors play a prominent role in the causes for ASD. This mainly occurs through DNA development and the absorption of nutrients by the cells forming a fetus in the womb. Worth further cites abnormal early brain development in infants as identifies through neuro-imaging may be another cause of ASD.

It is important to note that ASD, like many other medical conditions has not been exhaustively researched on. There is new information coming out occasionally regarding is causes, treatment and management.
