Running head: AUTISM 1 AUTISM 3 Autism Author Note Autism Introduction Etiology involves the study of the causes of diseases, the cause or origin of a disease. Also involves the study of causation and any causes, caution, or causality. The etiologic classification of a disease based on the cause, when known. This classification is important and useful in the consideration of biotic disease. The disease is classified as staphylococcal, rickettsial, or fungal. This condition affects specific cells in the body because they aim at a single point. Pathogenesis is the mechanism through which the cause operates to produce the pathological and clinical manifestations. Autism spectrum disorder (ASD) refers to a group of complex neurodevelopment disorders characterized by repetitive and characteristic patterns of behavior and difficulties with social communication and interaction. The symptoms are present from early childhood and affect daily functioning. Autism is a lifelong development disability that affects how a person communicates with, and relates to, other people. Also affects how they make sense of the world around them. The term “spectrum” refers to the wide range of symptoms, skills, and levels of disability in functioning that can occur in people with ASD. Some children and adults with ASD are fully able to perform all activities of daily living while others require substantial support to perform basic activities. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5, published in 2013) includes Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorders not otherwise specified (PDD-NOS) as part of ASD rather than as separate disorders. A diagnosis of ASD includes an assessment of intellectual disability and language impairment. It is a spectrum condition; all people with autism share certain difficulties that affect them in different ways. Some people with autism lead an independent life and many have accompanying difficulties.

These cell lines have been accepted to be the tool of examining the consequences of the genetic mutations. The cells are affected hence the blood circulation in the brain is widely hindered. This process leads to the development of disorders hence affecting the flow of blood in the body efficiently. This largely affects the brain since the cells are available in the brain. The pathologic condition hence creates the disorder in the brain hampering its function and proper operation of the brain. It therefore adversely affects the brain and the overall flow of blood. This leads to the development of deficiency in the brain because of lack of proper operation (Fiala et al., 2002). Organ system function affected by Autism Autism affects the social interaction and verbal communic ...
