At what age does autism manifest? [Answer from SLP]

Autism or autism spectrum disorder is a set of conditions that develop due to neurological or developmental disorders. It affects how the person interacts, behaves, communicates, and learns in several ways, thereby making them different from others.

The child faces delayed development in three major domains- social interaction, behavior and learning. The child can also present sensory issues (can be both hypersensitive or hyposensitive).

Being a neurodevelopmental disorder a child often presents with autism from a very young age itself, i.e., around 12 to 18 months. Few early signs autism are-

  • Lack of eye contact.

  • No reaction when their name is called.

  • Problems following other people's gestures

  • Difficulty using nonverbal modes of communication like pointing, etc.

Most children seem to develop normally till the age of 1 year and then go through a period of regression in development, when the symptoms of autism become more evident.

These symptoms are often overlooked as most parents aren't aware about the 'early' signs of autism. Hence, most children aren't diagnosed until the age of 3 years and ahead, when they start going school and there is an increase in social interaction.

Several researches have implicated the importance of early diagnosis and intervention in improving the quality of life of an autistic child. Early intervention often includes-

  • Family training

  • Speech therapy

  • Hearing impairment services

  • Physical therapy

  • Nutrition services
