New Delhi: Autism Spectrum Disorder (ASD) is a developmental condition linked to differences in brain development that affects how children communicate, behave, and interact with others. Since symptoms can vary widely from child to child, early recognition plays a crucial role in ensuring proper support and development.

Some children show signs in infancy, while in others, symptoms may become noticeable only after they start school. Understanding age-specific indicators can help parents take timely action.

Early Signs in Infants and Toddlers

In younger children, autism often becomes noticeable through differences in social engagement and responsiveness:

• Doesn’t respond to their name: Unlike most children, they may not react when called.
• Limited eye contact: Avoiding or not maintaining eye contact during interaction.
• Reduced smiling or expression: Lack of response when smiled at.
• High sensory sensitivity: Strong reactions to sounds, smells, or textures.
• Repetitive movements: Hand-flapping, rocking, or repeated gestures.
• Delayed or limited speech: Speaking less than expected for their age-or not at all.
• Lack of pretend play: Little to no interest in imaginative games like playing with dolls or toy kitchens.

As children grow, social and communication challenges may become more evident:

• Difficulty understanding emotions: Trouble reading facial expressions or feelings.
• Unusual communication patterns: Repeating phrases or talking only about preferred topics.
• Strict adherence to routine: Becoming upset with even small changes in schedule.
• Highly focused interests: Deep attachment to specific objects or subjects.
• Social difficulties: Struggling to make friends or preferring to be alone.
• Literal understanding of language: Difficulty grasping sarcasm, idioms, or figurative speech.

Why Early Detection Matters

Recognizing these signs early can make a significant difference. With timely intervention, therapy, and support, children with autism can improve communication skills, social interaction, and overall quality of life.
