Autism, in its shortest definition, is a neurodevelopmental disorder. Most individuals with autism have limited social interaction and communication skills. In addition to having difficulties in social interaction, individuals with autism experience communication deficits and have repetitive behaviors. Autism can occur as a result of genetic and environmental factors. 

Autism generally begins in the first 3 years of life and continues throughout life. It is a developmental disorder that can be expressed as the inability to establish appropriate verbal or non-verbal relationships with one's environment. Autism can be easily diagnosed with some simple tests. Early diagnosis and rehabilitation in cases of autism play a major and effective role in bringing these individuals to life. 

The cause of autism is not clearly known, but it is thought to be genetic. It is more common in boys than girls. Seventy percent of people with autism have mental retardation, while 10% have superior intelligence. Attention deficit, hyperactivity disorder, mood disorder and epilepsy can also be seen with autism.
