Special Interests and Autism
Most autistic individuals have one or more special interests. A special interest is an intense fixation that far exceeds a typical hobby or passion. An autistic person will typically have the desire to devote large portions of their time, and sometimes large portions of their money, to their special interests. Neurotypical people can and do experience fixations or passions, but having a special interest is a trait strongly associated with autism.
Here’s what you need to know about special interests, how they manifest, the benefits of encouraging them, and more.
What Are Signs of Autism in Adults? A Guide to Autistic Traits and Self-Discovery
When you picture someone with autism, there’s a good chance that a child comes to mind. Maybe your nephew or a member of your child’s class is diagnosed, so you’re familiar with some of the behaviors associated with the condition...or at least how they show up in children. But millions of autistic adults exist too, since autism is a distinct neurotype, not something you grow out of.
However, if the condition wasn’t assessed already in childhood, it can be harder to spot as an adult. In fact, the Centers for Disease Control and Prevention (CDC) estimates that one in 45 adults is autistic, and even more are likely undiagnosed.
Though there are many shared traits between the age groups, autism can present differently in adults than in children, which is something we'll discuss in depth within this article. But fundamentally, the signs of autism in adults include a range of characteristics like:
- Social interaction and communication differences
- Self-soothing and self-regulatory behaviors
- Sensory and processing differences
- Special interests and activities
- Emotional regulation and cognitive traits
If you suspect you may be autistic, you likely know the journey toward diagnosis isn’t so straightforward. It can be confusing and frustrating! Especially since no two people with autism are the same, and everyone has their own unique combination of strengths and challenges.
On top of that, many adults tend to mask their autistic behaviors to fit in with their neurotypical peers, oftentimes without even realizing it. Plus, thanks to gender and cultural bias and other stereotypes, countless autistic adults are overlooked due to their more subtle presentation of the condition.
That’s why Prosper Health is here to provide you with a clear, inclusive, neurodivergent-affirming breakdown of adult autism signs: what they are, why they’re often missed, and what to do if they resonate.
Understanding Autism and Relationships: Navigating Love, Family and Friendship
Autism can shape how individuals experience relationships, bringing unique strengths like honesty, loyalty, and focus. However, autism also creates challenges related to interpreting social cues or expressing emotions. These differences can easily lead to misunderstandings.
Autistic people thrive in relationships with clear communication and mutual understanding. For instance, they may prefer direct communication or need time to recharge after sensory overload. When these needs are respected, it fosters trust and support.
Autism Support Needs, Not Labels: A Guide to “Levels”
As an adult diagnosed first with autism as a child and again as an adult, I have witnessed firsthand the change in the way the DSM, or The Diagnostic and Statistical Manual of Mental Disorders, has changed to affirm autistic people. In 2013, the DSM updated its resources with an eye to supportive care.
Rather than labeling autistic people with misleading descriptors like high-functioning, low-functioning, or others, experts now categorize autistic individuals based on levels (one, two, or three). These levels indicate varying degrees of support needs, which are often fluid and can change over time.
Mental health professionals and patients can now navigate autism support without labels, a notable step forward in recognizing the individuality of care.
This DSM change also did away with the term pervasive developmental disorder, which encompassed disorders such as Aspergers and child disintegrative disorder. Instead, they were replaced by autism spectrum levels.
Kaila Hattis, MA, LMFT, founder and therapist of Pacific Coast Therapy, explains, “The change focuses less on what someone has to more on what someone needs, and changes the way families access services and disperse information on what their loved one needs."
While these three levels of autism don’t capture the full picture of autism spectrum disorder, they’re a move in the right direction to fuller, more nuanced autism treatment.

ADHD vs. Autism: Understanding the Differences and Overlaps
There is not a day that goes by that I don’t ask the question, “Is it ADHD or autism?”
As the parent of an AuDHD child—AuDHD being a colloquial term used to describe the dual diagnosis of both autism and ADHD—I still have difficulty differentiating between the two diagnoses. Is her stimming an autism or an ADHD trait? Which of her Individualized Education Plan (IEP) accommodations at school are tailored to her autism, and which ones are tailored to her ADHD? How is her ADHD medication affecting her autism traits?
My experience is with my 9-year-old daughter, but this dilemma is equally accurate for many adults. If you’re neurodivergent in any capacity, you’ve likely had moments where you’re comparing your characteristics, trying to determine if they could be a sign of autism, ADHD, or both.
AuDHD is becoming increasingly common among neurodivergent people, and those with both diagnoses deserve a clear understanding of autism and ADHD, and what it means when they co-occur.
That said, the two conditions are not the same! Many people will only get diagnosed with one condition or the other, so it's essential to understand how they differ.

Autistic Stimming: A Look Past the Stereotypes
Stimming, shorthand for self-stimulatory behavior, is a set of self-regulating behaviors commonly associated with autism spectrum disorder. Stimming can involve a wide variety of behaviors that stimulate one’s own senses, such as moving the body, playing with objects, or making vocalizations. Stimming, like many autistic behaviors, has been stigmatized, and often regarded as a symptom to be reduced by treatment. However, stimming is a normal, often harmless reality of autistic life, one that helps us regulate our senses and engage with the world more authentically.

Meltdowns in Autistic Adults: Why They Happen, What They’re Like, and How to Live with Them
“Meltdown” is not a term often associated with adult life, but for many autistic adults, meltdowns are a reality. For us, meltdowns are not what you might picture at first: an inconsolable child, acting out over not getting what they want; they’re more like the release valve on a neurobiological pressure cooker.

Neurotypical vs. Neurodivergent Experiences: Understanding Neurodiversity
Neurodivergence is a term coming into increasingly popular use—but what does it mean? With a growing number of people identifying as neurodivergent, it’s important to understand what neurodivergence is, how neurodiversity adds value to our institutions and communities, and the challenges a neurodivergent person often experiences in a neurotypical world.

Masking Autism: What It Is and Why It’s Exhausting
Imagine you’re hanging out with a group of friends. On the outside, this scenario looks like a typical get-together: Everyone is laughing, making eye contact, and visibly comfortable with one another.
But for some people, there is a very good chance that much of their behavior is the result of masking, or a concealment of their autistic traits. Sure, these people may come off socially at ease, but a debilitating dance is taking place behind their eyes.
“After I've been hanging out with people, I need to take a nap for one to two hours…my brain literally needs to shut off. I feel like a computer that needs to reboot,” says Aura Marquez, an author living with autism.
Marquez says she’s been masking since she was in late elementary school: “It’s gotten to the point where I can’t turn it off.”
Masking autism is how many neurodivergent people navigate a neurotypical world, so it’s important to understand the reasons behind this practice in order to minimize stigma. While masking may provide some benefits, it’s important to also remember the toll this behavior takes on one’s mental health.
That why learning how to also unmask, under the right conditions, is essential to helping autistic people feel comfortable in their own skin. This article will explore options for those who wish to stop masking, as well as support for those who do mask.

Understanding Neurodiversity Affirming Therapy: A Guide
Neurodiversity is a growing movement that celebrates neurodivergent perspectives and the many different ways people think and engage with the world. As the cultural conversation around neurodiversity has expanded, some institutions have begun evaluating ways to better include and uplift neurodivergent people. These changes are desperately needed, especially in mental health services. Neurodiversity-affirming therapy offers neurodivergent people mental health support that recognizes our value and embraces our inherent strengths.
