What Is Autism?

People with autism often have co-occurring conditions, including epilepsy, depression, anxiety and attention deficit hyperactivity disorder as well as challenging behaviours such as difficulty sleeping and self-injury. The level of intellectual functioning among autistic people varies widely, extending from profound impairment to superior levels. The abilities and needs of autistic people vary and can evolve over time. While some people with autism can live independently, others have severe disabilities and require life-long care and support.

Various DSP programs have been developed to explicitly deliver intervention systems through at-home parent implementation. Despite the recent development of parent training models, these interventions have demonstrated effectiveness in numerous studies, being evaluated as a probable efficacious mode of treatment. Early, intensive ABA therapy has demonstrated effectiveness in enhancing communication and adaptive functioning in preschool children; it is also well-established for improving the intellectual performance of that age group. Every child should receive well-child check-ups with a pediatrician or an early childhood health care provider.

Some have ignited controversy; others have increased the public’s general understanding of autism. At ARI, we hope that people will rely on evidence-based research to understand autism spectrum disorder better. When a person has more than two or more disorders, these conditions are known as comorbidities. The American Academy of Pediatrics encourages autism screening for all children at their 18 and 24-month well-child checkups. Parents and caregivers can also ask their pediatrician for an autism screening if they have concerns. In rare cases, individuals with autism reach adulthood before receiving a diagnosis. However, most individuals receive an autism diagnosis before the age of 8.

The earlier ASD is diagnosed, the sooner treatments and services can begin. Social-science scholars study those with autism in hopes to learn more about “autism as a culture, transcultural comparisons … and research on social movements.” Many autistic people have been successful in their fields.

In adults, some ASD symptoms can overlap with symptoms of other mental health disorders, such as anxiety disorder or attention-deficit/hyperactivity disorder . Caregivers and teachers are often the first to recognize ASD symptoms in older children and adolescents who attend school. The school’s special education team may perform an initial evaluation and then recommend that a child undergo additional evaluation with their primary health care provider or a health care provider who specialize in ASD. Considering caregivers’ experiences and concerns is an important part of the screening process for young children. The health care provider may ask questions about the child’s behaviors and evaluate those answers in combination with information from ASD screening tools and clinical observations of the child.

Some of these genes are known to modulate production of the GABA neurotransmitter, the nervous system’s main inhibitory neurotransmitter. These GABA-related genes are under-expressed in an ASD brain.
