Research on causes of autism has revealed that environment and genetics play a vital role on its causes (National Institute of Neurological Disorders and Stroke). Studies have identified some genes associated with the autism. Close study conducted on people experiencing this condition reveals some irregularities in some parts of the human brain. The research suggests that people who suffer autism have above or below normal level of neurotransmitters or serotonin (Volkmar 14). Neurotransmitters are chemicals that are responsible for message relay in the human brain from one neuron to the next through synapses. Neurotransmitters are situated at motor neurons axon endings. Serotonin is a neurotransmitter, which are responsible psychological effects of the human beings. Scientists believe that serotonin influence the functions of approximately 40 million brain cells (Frith 56). Serotonin influence directly or indirectly brain cells, which influence mood, appetite and sleep, learning, and memory, social behavior among others conditions (Frith 56). Abnormal level of serotonin may affect brain development at early stages of leading to complexity in learning, social relation among others. Scientists allude that the abnormalities observed on people suffering from autism suggest a disruption on genes responsible for fetal brain development (Frith 56). Further, the environment influences the brain development in early stages of human life. Inheritance of genes from parents has led to research on the role it plays in causes of autism. Studies suggest that parents who suffered from autism may bear children who bear children who suffer from the same disorder. Autism has numerous effects of social interaction or behavior of a person. Studies reveal that at early infancy, children who suffer from this disorder may focus on one item for along period or may show lack of response to people. Disengagement to the social environment is a common effect of autism. A child that suffers from the disorder may show withdrawal from the social aspects of her or his environment. A child that suffers from autism has difficulty in responding to his name or may avoid eye contact. Interpretation of social conditions is a difficulty that children who suffer from autism face. Understanding social clues such as tonal variation or facial expression is usually a problem. Lack of empathy and failure to embrace appropriate behavior is another observable effect of autism. Children who experience autism face difficulties in learning. They show repetitive moments for example, twirling and rocking, self-abusive behavior for example banging the head or biting. Language ability of the child may be poor or the child may begin speaking after his age mates. Researchers have observed that children with autism not how to interactively play together (Frith 46). In the playground, these children would play in seclusion or prefer a single game contrary to the wish of fellow playmates. Vocal ability of some children with this disability is often poor without consideration of fellow playmates. In some cases, some children often narrow their favorite topics and would sing or repeat them. Another profound effect of autism is the co-occurring conditions such as fragile X, (Fragile X is responsible for mental retardation), epileptic seizures, tuberous sclerosis, learning disabilities, Tourette syndrome, and lack of attention.
