Symptoms may be noticeable already in infancy, but become obvious in early childhood (from two to six years). There are five signs in a child’s behavior that can and should alert parents and make them consult a doctor. It is necessary to guard, if the child does not walk and does not speak up to 12 months,if he has a wandering gaze to one year, the absence of separate words to one and a half years, phrases from two or more words to two years, loss of speech and social skills at any age. The presence of one of the five signs does not mean that the child has a disease. To identify the presence and causes of autism, the baby is examined by a team of doctors: a neurologist, a psychologist, a pediatrician, a therapist, and other specialists. In fact, there are no specific tests that can identify autism. The final diagnosis can be made only when the child shows six or more of the 12 signs in the three listed areas: social interaction, communication and behavior.
