Causes Of Autism Spectrum Disorder

Autism spectrum disorder has now become a worldwide problem that affects a huge number of people around the globe. The causes for autism have been one of the most debatable topics in medical literature as well as latest research trying to figure out the roots of this disorder. Identifying the fundamental factors strongly linked with the emergence of autism spectrum disorder is critical for early detection, preventive interventions, and support. Although the exact causes for autism are still largely a mystery, many researchers believe that multiple risk factors contribute to the development of the disorder. Many researchers believe that the environment seems to play a considerable role too, because some specific genetic mutations have been linked with the chances of getting autism. Environmental factors, including the intake of certain chemicals during pregnancy, are also suspected to be important in this equation.

What is Autism?

Autism otherwise known as Autism Spectrum Disorder (ASD) is a condition that occurs due to the abnormal development of the nervous system and presents itself with difficulties in social communication and interactions as well as the loss of most repetitive behavior patterns. It is a spectrum disorder, in other words individuals may present with a mild to severe version of it. Autism is usually diagnosed in early childhood but sometimes the cases are not diagnosed until later in life. The early symptoms of autism may be presented with delayed speech development, lack of eye contact, repetitive movements or behaviors and trouble in social interactions. Individuals with autism continue to live with the disorder throughout their lifetime, but it is possible to detect and allow children to have fulfilling lives.

Prevalence and Statistics:

The autism spectrum disorder has been increasing so much in the past years that more and more people are being diagnosed. According to the Centers for Disease Control and Prevention (CDC), around one out of 150 children in the United States have been diagnosed with autism. It is evident that last year's figures achieved a huge jump in comparison to past years. The factors leading to the development of autism are not yet known to modern science. Some hold the view that greater awareness and improved diagnostic criteria are major contributors to the increasing number of cases reported. However, the researchers think that there might be some other factors mutually with the environment and genetic factor behind that.

Genetic Factors:

Genetic components had already been found to be an important factor in the development of autism spectrum disorders. It has been demonstrated in research that there is a direct link between specific gene mutations and chromosomal aberrations and the occurrence of autism. These types of genetic variations can interfere with the regular development of the brain and make this process more complicated for persons with autism spectrum disorder, which can also cause problems with the data and interaction with the surrounding world. It should be mentioned that not all the cases of autism can be explained by certain genetic mutations. Sometimes, both genetic and environmental factors may be involved. Research is ongoing that tries to figure out the complexity of genes and autism, which includes the search for the specific genes and genetic pathways that are involved.

Environmental Factors:

Additionally, researchers have been investigating the role of environmental factors in the formation of autism. It is still unclear what the exact environmental triggers but scientists suggest some of the risk factors. The effect of chemical exposure during the gestation period has also raised attention as a possible source of environmental factors in autism. These chemicals contain some air pollutants, pesticides, and certain medicines. However, we should point out that research in this field is still ongoing, and it is at this point not clear that environmental factors by themselves can cause autism.

Prenatal and Birth Factors:

The prenatal and birth factors have equally been considered as the suspects in the causation of autism. The occurrence of maternal infection during pregnancy, gestational diabetes, and obesity is related to an increased risk of autism. Apart from that, birth complications that include prematurity, low birth weight and lack of oxygen, increase the chances of autism development. These factors might well disturb the regular brain development and lead to autism symptoms.

Immunization Controversy:

Vaccines and autism have one of the more controversial connections and whether it exists at all is a widely discussed topic now. Yet, there is enough scientific evidence that proves that this idea is a fallacy. It is evident that many respectable academics found no causal relationship of autism and vaccinations. This myth has its roots back in a 1998 paper, which later had to be withdrawn. Wakefield, who performed research, showed the relationship between the MMR vaccination and autism. However, the flaws in the research methodology were found during the investigations which resulted in retracting of the study and disproving of the vaccine-autism link.

Neurological Differences:

Although autism is characterized by different neurological features in the brain, autism is highly different among the people who are diagnosed with the disorder. Researchers have used magnetic resonance imaging (MRI) technique to discover disrupted patterns of brain activity and connectivity from such people diagnosed with autism. These neurological differences can have an effect on the performance and integration of sensory information, social cognition, and communication abilities. The discovery of the neurobiological fundamentals of autism is fundamental for the development of evidence-based therapies and programs to meet the needs of the affected persons.

Co-occurring Conditions:

Cases with autism are generally included with disorders specifically mentioned above. These factors can thus make it more difficult to carry out the diagnosis and the therapy management of autism. For example, students with intellectual disabilities, ADHD, anxiety disorders, and epilepsy may have increased chances for comorbidities. Comorbid medical issues among persons with autism can present with a wide range, demonstrating a complex nature of the disorder. Individualized assessments and treatment plans are an essential part of the treatment process; they address specific needs of each person with the autism spectrum and the accompanying disorders.

Early Detection and Intervention:

Early detection and intervention are vital because they may be the main factor that substantially improves treatment efficacy for autistic patients. Research has demonstrated that early intervention can result in a very positive growth curve, in that children with autism tend to display increased levels of development, social skills, and adaptability. Diagnostic screening devices, like Modified Checklist for Autism in Toddlers (M-CHAT) can help to identify early signs of autism among the toddlers. Applied behavior analysis (ABA) and speech therapy programs that can be initiated early on are devised with the purpose of identifying the individual needs of autistic people and promoting skills as well as independence.

Conclusion:

In short, the causes of autism spectrum disorder are complex, and their interactions are yet not well understood. However, genetics, environmental, prenatal and birth factors have all been brought to the fore but the exact mechanisms underlying autism are as yet still unclear. It is vital to expose this myth that vaccines lead to autism because it contributes to wrong perceptions concerning vaccines and ultimately undermines public health. With the aid of ongoing research, the neurological mechanism of autism is being unraveled and such information is instrumental in designing target interventions and support programs for individuals with autism. EPSCC offers different kinds of support services for children with the autistic spectrum disorders, including individual and group training that is adapted to meet the needs of each family member. Creating awareness on autism that promotes empathy, inclusivity, and support for autistic individuals is fundamental. Through the knowledge of the causes and the nature of autism, we can establish an environment which is friendly and full of empathy where autistic individuals can thrive.
