What are the causes of Autism Spectrum Disorder?
There is no one knew about the causing agent of ASD. Most of the scientists agreed that gene is one of the most risk factors in autism spectrum disorder. Specific gene causes can only be identified in the low level of cases. These cases include specific genetic syndromes associated with ASD and rare changes in the genetic code, and it simply increases the risk of autism spectrum disorder. Environmental factors are playing a vital role in the causes of ASD t
A hat may be vaccination, maternal smoking, and most likely assisted reproductive technologies are unrelated to the risk of ASD. On the contrary, advanced parental age is associated with a higher risk of ASD. Birth complications are the major risk factor of neurological disorders. In contrast, other pregnancy-related factors such as maternal obesity, maternal diabetes, and cesarean section have shown a less intense (but significant) association with the risk of ASD.
Why is the screening of ASD important?
The diagnosis of ASD is essential, and it's also challenging because it may or may not vary from the normal one. A screening makes the diagnosis of ASD of evaluation. The evaluation should include standardized observations of the individual, assessments of their learning and cognitive abilities, behavior across multiple settings, and medical and developmental history.
Many children with autism spectrum disorder (ASD)show several developmental differences in childhood in social and language skills. Because they had typical milestones like sit, crawl, and walk on time, but they have less apparent differences in the development of behaviors. BeAutismAutism is a spectrum disorder; it can range from very mild to more severe depending on children's age groups. Some childrenAutismautism appear normal before age 1 or 2 and then suddenly changed and lose language and social skills they had previously gained. This is called the regressive tyAutismautism.
