What is Autism or Autism Spectrum Disorder?

Definition of Autism

Autism is a lifelong complex neurobehavioral condition where how people perceive the world and interact with others is affected. All people suffering from autism share common difficulties in speech and in non-verbal communications and have learning disabilities. Repetitive behaviour and difficulty with social skills are some of difficulties faced by autistic people. Due to the broad spectrum of disabilities and impairments associated with the disease, autism is usually referred to as 'Autism spectrum Disease’.

What Is Autism Spectrum Disorder?

Autism Spectrum disorder (ASD) is a wide range of group of neurological and developmental disorders which may affect a child at early stages and can last for lifetime as there is no such treatment available which can treat this disorder completely. ASD is the name given to various groups of developmental disorders including Asperger’s Syndrome and many other neurological disorders.

ASD affects the communication, social and learning skills of a person. It is estimated that boys are more prone to ASD as compared to girls. Almost 1 in every 1000 people in the UK has ASD.

Autism Spectrum Disorder definition refers it as “Spectrum” disorder because it includes a wide range of symptoms among the population suffering from ASD. The symptoms may vary from low to mild to highly autistic depending upon a person’s age and circumstances and also based on whether a person is diagnosed in the earlier ages or later on. If a child is diagnosed with ASD in early ages, there may be possibilities to control many of the symptoms like delayed communication, learning disability or difficulty in verbal and non-verbal communication, social communication and repetitive behaviours. A child with ASD may often find himself lost in his own world, unable to make eye contact, face difficulty in reading words and phrases, and has limited interests and routine obsessions. The symptoms may vary from person to person. Autism is an incurable disease. However, the symptoms can be controlled by early detection and starting the therapies as early as possible.

Initially, in 1943, when Dr.Leo Kanner first described autism, people thought that Autism was an early form of Schizophrenia. This thought created a belief that Autism was a result of bad parenting. However, researchers later on confirmed that autism was not caused because of bad parenting.
