In 2018, the Centers for Disease Control and Prevention (CDC) determined that approximately 1 in 59 children is diagnosed with Autism Spectrum Disorder (ASD). Boys are still four times more likely be diagnosed with ASD; however, research indicates that the diagnosis is often missed in girls, especially those who have average intelligence and “milder” forms of ASD. To understand why ASD is more often missed in girls, let’s explore the differences between boys and girls with ASD. This discussion will focus on children with average to above average intelligence (about 50% of all children diagnosed with ASD).
| Boys | Girls |
| Poor impulse control, more acting out | Likely to be quiet and withdrawn |
| Disruptive behaviors in the classroom setting | Tend to be reserved and cooperative at school |
| Frequent repetitive motor behaviors that are directly observable | Lower frequency of these motor behaviors |
| Lack of interest in imaginary play | Very much engaged in imaginary play |
| Restricted interests may seem unusual – e.g., train schedules, maps, windmills | Restricted interests may seem “age appropriate” – e.g., horses, unicorns, ballet |
| Trouble making friends | Might have a few friends |
| Likely to exhibit angry outbursts when frustrated/anxious | Likely to engage in self-harm or other behaviors that are not observed by others when frustrated/anxious |
| Lack of awareness of being different or not fitting in | More motivated to fit in and “hide” social difficulties – might try to imitate the behavior of a peer that is perceived as popular |
Due to these differences, the diagnosis of ASD is often missed in young girls. Adults might agree that a girl is “odd” or “quirky,” but dismiss these concerns because she has good eye contact, has some friends, and does not engage in hand flapping or other unusual behaviors. Unfortunately, other girls might be misdiagnosed, which could lead to ineffective or inappropriate treatment interventions. Most commonly, they might be misdiagnosed with ADHD or Anxiety Disorder.
In many cases, girls with ASD have increasing difficulties with social interactions as they get older and demands get higher. A young girl with ASD might be able to “get by” in social interactions but by the time she reaches adolescence, she is not able to navigate the intricacies of the social milieu. This can lead to social isolation and high risk of being bullied or rejected by peers.
Unfortunately, a missed diagnosis of ASD for a young girl can have long-reaching ramifications. She might experience depression, anxiety and/or low self-esteem, wondering why she doesn’t “fit in” and “feels different” from other girls. She might start to struggle in school or disconnect from activities that she used to enjoy. Moreover, missing the diagnosis in childhood means that she did not receive services to support her social and peer interaction skills during her formative years.
As always, when parents or other caregivers have concerns about a child’s development, it is important to seek an evaluation from a professional. And if the findings do not feel quite right, parents should never feel uncomfortable about seeking a second opinion.
