Autism spectrum disorders, as they are known by today, or shortened autismare considered to be the most common developmental disabilities that appear at an early age and are a lifelong condition. Data also shows the alarming fact that the prevalence of autism is 1 in 150 children, meaning that every 21 minutes a child is born that will be diagnosed with autism spectrum disorder. Today autism spectrum disorder is labeled under the term pervasive developmental disorders, which are characterised by the pervasive impairment of a larger number of developmental areas, such as social interaction and communication or the appearance of stereotypical forms of behaviour, restricted interests and repetitive activities. Behaviour patterns such as these affect the ability to satisfy basic human needs and in consequence affect the very quality of life. The early recognition of the disorder and proper diagnosis are of immense importance, so that the child may start an apppropriate and continuous system of rehabilitation and education. The study was conducted with the parents of children aged 12 to 18 months. The M-CHAT questionnaire was the instrument used in the study to examine the indentifiers of pervasive disorders. The questionnaire was filled out via social networks, the main goal being to identify how many children in the questioned sample possess more than three risk factors for developing a developmental disorder, while the secondary objective was focused on whether the age of the parent and sex of the child was linked to the number of risk factors in developing a developmental disorder. 94 parents of children between the ages of 12 and 18 months participated in the study. The end results showed that 28,7% of children had more than three risk factors to develop a developmental disorder, furthermore there was no correlation between the age of the parents and the number of risk factors, as well as no correlation between the sex of the child and number of risk factors. Due to it's complexity autism spectrum disorder deserves more attention from specialists as well as more concern from the community. It is necessary to educate and increase awareness in the community about autism spectrum disorder and the need for early diagnosis and recognition of symptoms. Intensive early intervention in children enables better progress, acquiring basic skills, communication, comprehension and better acceptance of the diagnosis. The reforewhen a child shows the first signs of the disorder it should be integrated into individualized educational programmes.
