Early autism signs often appear before age 3:Experts say timely diagnosis improves and helps children gain better communication skills

Early signs of autism can appear before the age of three, and experts say early diagnosis is key to better support. Autism, also known as Autism Spectrum Disorder (ASD), affects how a person communicates, builds relationships and understands the world. Health experts say that recognising these signs early can help families seek timely care and support. Early signs appear between one and three Doctors say the first signs of autism usually appear between the ages of one and three, although in some cases they can be noticed even earlier. One of the most common early indicators is a delay in speech or language development. Some children may not respond when their name is called, avoid eye contact, or not use gestures like pointing or waving. Social behaviour may feel slightly different Children with autism may prefer to play alone rather than with others. Experts explain that understanding facial expressions or emotions can be difficult for them, not due to lack of care, but because social cues do not come naturally. Activities such as back-and-forth play or copying others may also be limited. Repetitive behaviours and strong routines are common Health specialists highlight that repetitive behaviours are another key sign. These may include hand-flapping, rocking, or spinning. Many children also develop a strong attachment to routines and may become upset if there are small changes. Some may show intense interest in specific objects or topics. Sensitivity to sounds, lights, and textures may vary Sensory sensitivity is also common. A child may feel overwhelmed by sounds, lights, textures or smells. In contrast, some children may show very little reaction to sensory input, including pain, which can delay detection. Early diagnosis plays a crucial developmental role Experts emphasise that early diagnosis plays a crucial role in a child’s development. During the early years, the brain is more adaptable, making it an ideal time for intervention. Support such as speech therapy, occupational therapy and behavioural programmes can improve communication skills, social interaction and independence. Diagnosis helps parents understand the child’s needs better For parents, receiving a diagnosis can be challenging but often brings clarity. It helps them understand their child’s needs and access the right support systems, including therapies and school assistance. Many families say it replaces uncertainty with a clearer direction. Delayed diagnosis may impact a child development progress Health professionals warn that delayed diagnosis can lead to missed opportunities for early support. Without proper understanding, a child may be misunderstood or not receive the help needed for their growth and learning. Experts advise parents to seek help early Doctors advise parents and caregivers to trust their instincts. If something feels unusual in a child’s development, seeking professional advice early can make a significant difference. Early support, they say, can positively shape a child’s future. Autism is a spectrum condition The condition is called a spectrum because every individual experiences autism differently. What it looks like in one child may be very different in another. Dr Dinesh Chouksey, Consultant Neurologist at Kokilaben Dhirubhai Ambani Hospital in Indore, says understanding these differences is key for parents and caregivers.
