Introduction
Some early signs of autism may begin to appear around the time a child is 1 year old, such as lack of eye contact, delayed response to sounds, and dislike of being hugged. By age 18 months, if a child has not started using certain gestures, such as pointing, or by age 2 has not spoken any words, these may be potential warning signs.
Autism is usually detected in children between the ages of 1 and 3, although the exact timing may vary.
Some early signs of autism may begin to appear around the age of 1 year, such as lack of eye contact, delayed responses to sounds, and dislike of being hugged. By around 18 months, if a child has not started using gestures like pointing, or by age 2 has not spoken any words, these could be potential warning signs. Between ages 1 and 3, symptoms of autism become more apparent, primarily including impairments in social interaction, language difficulties, and abnormal interests and behaviors.
Children with autism may show little interest in interacting with others, avoid eye contact, and have difficulty understanding others' thoughts or emotions. They may experience delayed language development, impaired comprehension, and abnormalities in the form and content of their speech. Their range of interests may be narrow, their behaviors rigidly repetitive, and they may show little interest in new things or environments. Autism is generally diagnosed around age 3, although some cases are identified at earlier ages.
Parents should closely monitor their child's behavioral and developmental progress, and seek timely medical consultation with a specialist if concerns arise. Early identification and intervention can help improve the quality of life for children with autism.
