NHS data shows autism diagnoses have increased by 52% since last year, with more than 23,000 recorded across the UK. This rise reflects an evolving understanding of neurodevelopmental conditions, improvements in diagnosis, and decreasing stigma.
Online search behaviour mirrors this trend. Data from Benenden Health reveals that searches for “resources for autism” and “autism test for adults” increased by 300% and 100%, respectively, over the last three months.
Despite the increase in adult assessments, misconceptions create unnecessary challenges for those with an Autism Spectrum Condition (ASC) diagnosis. Kelly Fisher, Health and Well-Being Nurse at Benenden Health, emphasised why challenging these ideas matters: “Autism stereotypes like ‘everyone is on the autism spectrum’ can cause confusion about symptoms and what autism truly is, devaluing the experiences of autistic individuals. These stereotypes can also perpetuate stigma, making it difficult for those who need it to receive the right care.”
“If you or a loved one is showing signs of autism, always speak to a healthcare professional to better understand the diagnosis process, as well as receive advice and support on how to manage current and/or potential symptoms.”
To assist, Fisher addresses five common misconceptions.
Myth 1: Vaccines cause autism
There is no scientific evidence that vaccines, including the MMR vaccine, cause autism.
While the exact causes of autism remain unclear, research indicates that it involves differences in brain development and wiring. Genetics play an important role in the development of autism, although autism is not caused by a single genetic factor.
Myth 2: People can outgrow autism
Autism is a lifelong neurodevelopmental condition that can be diagnosed in both children and adults through a complex, multi-professional assessment process.
Females can face diagnostic delays because autistic traits may present differently, and some may consciously or unconsciously “mask” their traits to fit social expectations. However, there is no single typical age at which autistic females are diagnosed. Support should be tailored to the individual’s needs and can help reduce difficulties in daily life at any age.
Myth 3: All autistic people possess exceptional intelligence
Media depictions often reinforce stereotypes that autistic people are exceptionally intelligent. However, intelligence varies widely among autistic people, just as it does across the wider population, and an autism diagnosis does not determine a person’s intellectual ability.
If you want to retain the specific 45% and 32% figures, I would recommend checking the original source first, as IQ distributions can vary considerably between studies and samples.
Myth 4: Everyone is on the spectrum
A 2020 UK government study estimated that around 1 in 100 people in the UK are autistic, although autism remains under-recognised. The term “spectrum” reflects the wide range of traits and support needs among autistic people, from relatively limited support to substantial daily assistance. It does not mean that everyone is autistic.
Because some behaviours associated with autism can overlap with conditions such as ADHD or emotional dysregulation, accurate identification may require a multidisciplinary assessment.
Myth 5: Autism is a mental health disorder
Autism is a neurodevelopmental condition, not a mental health disorder, although navigating a world where autism is often misunderstood or stigmatised can affect mental well-being. Research indicates that around 8 in 10 autistic people experience conditions such as anxiety or depression.
Seeking advice from healthcare professionals, reputable online resources, local support groups, and personal networks can help individuals and caregivers manage stress and access appropriate support. Further information is available through the Benenden Health website.
