The Hidden Autism That Parents Miss
Your child is bright, polite, and does well in school. They have friends. They seem fine. So when a teacher or relative suggests autism, it feels like it can't possibly be right. But here's what researchers are discovering: some of the most intelligent, socially skilled autistic children are the hardest to spot—because they're working incredibly hard to hide who they really are.
A recent study published in Frontiers in Child and Adolescent Psychiatry looked at 46 children and teenagers in Singapore and other regions who weren't diagnosed with autism until after age six. The researchers wanted to understand why—why did these children slip through the cracks for so long?
What the Research Found
The answers are eye-opening, especially for parents of girls. The study revealed that girls with autism are much more likely to mask their autistic traits than boys. This 'masking' or 'camouflaging' means they're consciously or unconsciously copying how their peers behave, suppressing their natural interests, and forcing themselves to make eye contact and small talk—even when it exhausts them.
Interestingly, many of these late-diagnosed children were actually quite gifted academically or had naturally easy-going temperaments. These strengths, while wonderful, actually made their autism harder to see. Their intelligence helped them figure out social 'rules.' Their calm nature meant fewer behavioral meltdowns to alert adults.
The study also found that many of these children had other conditions alongside autism, most commonly ADHD. Because clinicians and parents focused on the ADHD diagnosis—the hyperactivity, inattention, or impulsivity—the underlying autism remained invisible.
What This Means for Singapore Families
In Singapore's high-pressure academic environment, this research carries special weight. Our education system often rewards the very traits that help autistic children camouflage: sitting still, following rules precisely, academic achievement. A brilliant student who sits quietly and scores well may never be flagged for further assessment—even if they're struggling internally with sensory sensitivities, social anxiety, or repetitive thought patterns.
Singapore parents often see their child's success as evidence they're neurotypical. But late-diagnosed autism shows us that success and autism can coexist. The child who excels at math but has few friends, who becomes anxious at birthday parties, or who needs extreme routine and predictability—these are still signs worth investigating, regardless of grades.
Additionally, girls in Singapore's competitive environment may feel even more pressure to fit in and perform well academically, making their masking more intense and their diagnosis even later.
Three Things to Do Right Now
- Look beyond good grades and behavior. If your child is academically strong but struggles socially, seems anxious in unstructured settings, or has intense, narrow interests, don't assume all is well. Request an autism assessment even if your child 'seems fine.' Late diagnosis is common in gifted children.
- Pay special attention if you have a daughter. Girls mask autism more effectively than boys. Notice if your daughter is exhausted after school, has very few close friendships despite appearing socially capable, or seems 'too good to be true' at home. These can all be signs of significant masking.
- Consider the whole picture, not just one diagnosis. If your child has been diagnosed with ADHD, anxiety, or being 'highly sensitive,' ask your pediatrician about co-occurring autism. The two often go together, and treating autism specifically—rather than just ADHD symptoms—can be transformative.
