The inclusion of these also indicated that now more research hypotheses supported that the roots of autism were in genetics. For decades, throughout the s, many studies were done to specifically identify the genes that contribute to autism. Many genes found to be linked to the disorder, however, not one of them was exclusively related to autism.
That is why experts decided to make autism an umbrella diagnosis with a spectrum ranging from mild to severe. Around these times, clinicians did not have a consistent approach to diagnosis of autism. These characteristics both present in early childhood and each group includes specific behaviors.
Clinicians have to identify a certain number of these specific behaviors to make a diagnosis. Autism diagnosis has changed drastically over the years. Today, the DSM-5 describes the condition as autism spectrum disorder.
Here is a timeline of events that lead to this diagnosis. He later described their condition as early infantile autism. He reported cases where the patients were all boys and had high intelligence but had problems in social interactions. This theory has been debunked solidly. At this time, researchers did not consider the biology or genetics involved, but only looked at the impact of life experiences. To this end, it was differentiated from the diagnosis of childhood schizophrenia. The manual also included a checklist for diagnostic criteria in order to eliminate the lack of consistency between diagnoses made by clinicians.
Conclusion This article has focused on the origins and foundations of autism as a concept in Britain. Notes 1. References Anthony E. Anthony E. Baird G. Baron-Cohen S. Bartak L. Bender L. Bishop D.

That Howe would emerge as a thundering advocate for teaching children who were disabled would have stunned those who knew him only in his mischievous younger years.
Around the same time, his mother died; he returned to school a changed man. He graduated in , picked up a medical degree at Harvard in , and then embarked on a lifetime of high-minded challenges, always as a champion of the underdog.
He headed for Greece first, and the front lines of a war, serving as a battlefield doctor on the side of the Greek revolutionaries rising up against Turkish rule. After that, he raised funds for Polish patriots in their struggle to throw off czarist domination. He spent a month of the winter of in jail in Prussia, where he had been holding clandestine rendezvous with Polish contacts. Howe had a second reason for making that trip to Prussia. By then, on what seems like a whim, he had agreed to become the first director for the New England Asylum for the Blind.
He learned well. Within a decade and a half, Howe was a celebrated educator. His school, renamed after a financial benefactor, Thomas Handasyd Perkins, was a resounding success. Blind children were reading and writing, appreciating poetry, playing music and doing math. One student, Laura Bridgman, who was both deaf and blind, became a worldwide celebrity, especially after Charles Dickens published an account of spending time in her company in January of Some decades later, the Perkins School would enroll its most famous student—Helen Keller.
In November , the U. Centers for Disease Control and Prevention reported a new estimate of the prevalence of autism in children ages 3 to The figure, 1 in 45, is the highest ever announced by the CDC, up from 1 in in Though many news reports described the figure as an alarming jump in the number of people with the condition, in fact no study carried out to date can be said to tell us exactly how much autism exists in the population at any given moment.
Instead, there are estimates with wide margins of uncertainty. Secretin injections are used for diagnostic purposes for gastrointestinal problems such as ulcers or pancreatic disease, but are not FDA approved for any other use.
There is no reliable evidence to suggest secretin has any effect on improving any behavioral symptoms of autism spectrum disorder. In fact, the vast majority of research on the treatment has found no clinically significant differences between secretin treatments and a placebo. Despite the lack of evidence, however, secretin injections are continued to be used as a treatment for autism in children, with influential clinicians in the field continuing to advocate for its use.
Pharmaceutical treatments have had increasing success in diminishing some of the behavioral symptoms of autism spectrum disorders, such as aggression, irritability, and self-inflicting injurious behaviors. Additionally, by reducing these intrusive behaviors, pharmaceutical treatments can aid the efficacy of other behavioral therapies such as applied behavior analysis ABA , the most successful treatment for autism spectrum disorders.
Risperidone Risperdal was the first FDA-approved medication for treating symptoms associated with autism spectrum disorders in children. Known to act on dopamine receptors, multiple studies have shown risperidone has significant effects in reducing number of tantrums, aggressive behaviors, self-injury and other problematic behaviors among children with autism. The most common adverse effects of risperidone include dizziness, dry mouth, and increased appetite. Aripiprazole Abilify is another FDA-approved medication for children with autism, specifically used to reduce irritability associated with the disorder.
The exact mechanism of action is still unknown, but thought to be a partial agonist to both serotonin and dopamine receptors. Not only does evidence show that aripiprazole improves symptoms of irritability in children with autism, it also has been shown to significantly improve hyperactivity and quality of life.
Relatively common side effects of the drug include weight gain and sedation. Clozapine Clozaril, Clopine is an atypical second generation antipsychotic and was commonly used for the treatment of symptoms of autism before FDA approval for Risperidone and Aripiprazole.
Clozapine is extensively used for treatment of schizophrenia, including reducing suicidal behaviors and aggression. Clozapine as a medication for autism spectrum disorders has been found to significantly reduce the number of days with aggression in children, and reduce the amount of psychotropic medications necessary to treat adverse behaviors.
However, clozapine has significant side effects including excessive weight gain and metabolic syndrome and is infrequently used as a first-line treatment in children. In addition, several studies have should Haloperidol is effective in improving social withdrawal and hyperactivity symptoms of autism in children.
However, long-term administration of Haloperidol can have severe side effects of tardive dyskinesia involuntary muscle movements , and should only be used with careful observation by a physician. In , infantile autism in the DSM is replaced by a more expansive definition of autism that includes diagnostic criteria.
The Individuals with Disability Act IDEA was originally passed by congress in to ensure all children receive free and public education regardless of any disability. In , an amendment was passed requiring special education for individuals with disabilities that allows students to access the general education curriculum that other students have.
For the first time, this allowed children with autism spectrum disorders access to the same level of education as other children. Special education for children with autism allows children to succeed in an education setting amongst their peers.
These special education programs have been shown to greatly improve quality of life and allow children to succeed. The reconceptualization of autism changed the landscape of autism treatment in two important ways. First, the idea that autism is present from birth and thus in part a biological condition paved the way for psychopharmacological interventions, and second, autism is a social and emotional disorder distinct from other mental illnesses and should be treated as such. The Centers for Disease Control and Prevention estimates that autism spectrum disorders occur in approximately 1 out of every 68 children, and is more prevalent in boys than girls.
Although the most obvious symptoms of autism typically appear between 2 and 3 years of age, autism can be diagnosed as early as 18 months in children.
