Yes, intelligence masking autism is a phenomenon where highly intelligent individuals with autism may not show obvious signs of the condition during childhood, leading to a late diagnosis in adulthood. This can happen because their cognitive abilities may allow them to compensate for difficulties in social interactions, communication, and sensory processing, effectively masking the traits of autism. These individuals often go through life without realising their challenges are related to autism, sometimes only recognising them later when the coping mechanisms no longer suffice.

For many people, gifted traits can also mask autism, especially in those with high intellectual functioning. Their advanced abilities in certain areas can make them appear neurotypical, even if they experience difficulties in other areas of life. As they grow older and social or workplace expectations become more demanding, these hidden overlooked signs may become more apparent, prompting individuals to seek a diagnosis later in life.

Common Symptoms of Intelligence Masking Autism

The common symptoms of intelligence masking autism are as follows:

Difficulty with Social Nuance:

Highly intelligent adults may excel in academics or specific subjects but struggle to understand social cues or engage in casual conversations. Social skills training can help build communication strategies tailored to their unique challenges.

Overthinking and Perfectionism:

Individuals with autism may engage in intense focus on specific topics or perfectionistic tendencies, which can be mistaken for OCD. CBT can help individuals manage these tendencies and reduce stress associated with the need for perfection.

Emotional Sensitivity:

Autistic individuals with high intelligence might struggle with emotional regulation, misinterpreting or overreacting to situations. Emotional regulation therapy can help address these difficulties and improve coping skills.
