Diagnostic and statistical manual of mental disorders (DSM-5) defines autism spectrum disorder (ASD) as a neurodevelopmental disorder characterized by deficit in social communication and social interaction as well as limited, repetitive patterns of behavior, interests and activities (American Psychiatric Association, 2013.). Although ASD is most often diagnosed around the age of 4 (Center for disease control and prevention, 2012.), there is still a trend towards earlier recognition of signs that point to ASD and thus the importance of early intervention and its impact on the development of communication, language, and speech. In addition to the importance of early intervention itself, the importance of the child’s parents, who in cooperation with experts of different profiles, can greatly contribute to the future development of a child with an autism spectrum disorder, is also emphasized. This paper will try to show the features of autism spectrum disorder, its impact on the child, but also on the family as a system of support and help and the importance of early intervention by an adequate team of experts, with the aim for the best possible further development and progress of the child with this disorder.
