Autism Spectrum Disorder is a developmental condition characterized by persistent deficits in social communication and restricted, repetitive patterns of behaviour and interest.
The word ‘spectrum’ is used as individuals on the autism spectrum show varying levels of autism-related behaviours and abilities.
Signs of autism can be noticed in children from as young as 12 months old. Autism-related differences or difficulties often persist in adulthood, although these can change as a child grows and improves.
Children on the autism spectrum can be very different in their cognitive abilities and everyday living skills for independence and group learning. Whilst some children with autism have learning difficulties and intellectual challenges, there are others with normal or exceptional cognitive abilities.
Even so, children on the autism spectrum have their unique strengths. They can learn, thrive, and grow up to be happy, healthy, and achieving adults.
Signs of Autism
For very young children between 1 and 3 years old, signs of autism include:
For older children and children with more fluent speech, they may show any of the above signs as well as the following:
There is no known way of preventing autism.
In most cases, no cause may be identified. Genetics play an important role, as autism is more common in some genetic conditions and in families who already have one child with autism. Autism is also more common in children born before 35 weeks’ gestation or who weighed under 2.5 kg at birth. Parents over 40 years old are also more likely to have a child with autism. Importantly, parenting styles and vaccines do NOT cause autism.
Screening for Early Signs of Autism in Children
The Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F; Robins, Fein, & Barton, 2009) is a parent-report autism screening tool to assess the likelihood of autism in 16- to 30-month-old toddlers. The results will indicate whether further evaluation may be needed. You may use the results from this screener for discussion with your child’s doctor.

If the M-CHAT-R/F screen is negative but you still have concerns that your child may have autism, please continue to seek professional advice from your child’s doctor.
Some groups of children are at higher likelihood of having autism. As such, screening for autism is recommended for the following:
There is no known cure for autism. However, with appropriate education and early intervention, children on the autism spectrum can maximise their communication and interaction skills. Due to the wide spectrum of abilities and support needs, some autistic children may be able to integrate into mainstream schools whereas others may need the specialised support offered by special education (SPED) schools.
Medication is only used in autism to manage associated conditions such as attention-deficit/hyperactivity disorder (ADHD), epilepsy or irritability, but many autistic children may not have these associated conditions at all. There is no evidence that special diets or supplements can improve autism symptoms – in fact, it is more important that autistic children eat a healthy, balanced diet.
How Can I Seek Help?
If you have concerns that your child may be on the autism spectrum or notice some of the signs listed above, you are encouraged to speak to a polyclinic or private general practitioner (GP), or your child’s paediatrician. A referral may be made to one of the following specialist services for further evaluation and support.
For preschool children (6 years and below or not yet in Primary One), they may be referred to:
For school-age children (i.e., Primary One and above), they may be referred to:
