Various studies have been conducted so far in order to conduct a longitudinal population-based autism cohort, the main aim of this is to ensure that the people are able to form the idea about the early symptoms of the retarded or disorders in the mindset and understand how these disorders keep on aggravating with every passing age. Therefore, what matters the most in such situations is to ensure that the people are provided with the best models to understand the specific needs of these kinds of people who try to exhibit different symptoms of autism during the different phases of their lives. These studies have been able to show how different kinds of people have been able to produce the different levels of intelligence quotient as they progress in their age from 12 to 24. However, despite that the aggregate score of their autism has remained somewhat similar to each other. Therefore, what matters the most in such situations is to ensure that people are able to get the care they require to maintain an efficient life. This shows that the people who are the victims of autism are able to get awareness with the passing age, however, this is highly unlikely to assure that the autism symptoms will decrease. Therefore, it was observed that all the people with the population limit of 23 years with autism across teh adolescent period was linked with improving sumtoms and there were robust scores observed.
