Every parent strives to foster their child’s physical and mental well-being. Autism spectrum disorder (ASD) is a particular mental disorder parents should be aware of. It is a common developmental disability resulting in impaired cognitive, behavioral, affective, and social functioning. Thankfully, a timely diagnosis and expert intervention can help control its symptoms. In children, the early signs of autism appear between 12 to 18 months of age and sometimes prior. Repetitive movements Repetitive movements, including hand flapping, rocking, twirling, and turning switches on and off, can indicate the onset of autism. Some studies suggest that such repetitive behavior displayed by patients is associated with an imbalance of corticostriatal connectivity. Echolalia While repeating words and phrases is a natural part of child development, kids with autism often engage in excessive verbal repetitions, known as echolalia. Such repetitive speech tends to persist beyond three years of age and is particularly prominent among children with autism who are grappling with delayed speech development. Lack of eye contact Researchers believe that a lack of eye contact is one of the primary indicators of the disorder. Since this lack of eye contact stems from the child’s inability to communicate and interact with others, it is typically accompanied by the inability to partake in and sustain social interactions and engage in non-verbal communication.
