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
Many autistic people experience relationship challenges—whether they’re romantic or platonic—in environments shaped around non-autistic social norms. Some unwritten rules and behaviors don’t necessarily come naturally to neurodivergent people.
Christal Castagnozzi, a clinical and school psychologist who received a late autism diagnosis, says that while she had friends growing up, there was an “underlying sense of being misunderstood.” She feels she “struggled to access deeper, more meaningful connections,” and ultimately believed she didn’t belong, even when her friends included her in their social activities.
Even in romantic relationships, Castagnozzi says she had difficulty “interpreting cues, flirting, [her partner’s] intentions, and emotional subtext.”
If any of these experiences sound familiar, you are not alone. But more importantly, the challenges of autism and relationships are not a personal failing. They are often due to differences in communication style, sensory processing, social expectations, and mutual misunderstanding between autistic and non-autistic people. Castagnozzi says what made a difference for her was forming relationships with neurodivergent individuals who provided “less pressure to mask and more space for directness and authenticity.”
In this article, we’ll examine how autism shapes all kinds of relationships, the roots of certain challenges, and practical strategies for effectively navigating relationships.
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.

Autism and Depression
Depression is one of the most common diagnoses to co-occur with autism spectrum disorder. As many as 40% of autistic individuals will have depression at some point during their lives. Researchers don’t have a definitive answer as to why––but many believe social stigma, mistreatment and insufficient support have to do with it.
Understanding the link between autism and depression can go a long way toward helping autistic individuals manage, or even move past, depression.

Mindfulness Practices for Autistic Adults: Enhancing Daily Life and Emotional Health
Mindfulness is the practice of being present and engaged with your thoughts, emotions and surroundings without judgment. For adults with autism spectrum disorder, mindfulness is a valuable tool for managing sensory overload, emotional regulation and stress. While mindfulness is often associated with a meditation practice, it doesn’t have to mean sitting in silence. The beauty of mindfulness is that it can be adapted to fit personal needs.
Autistic individuals often experience heightened sensory processing and deep focus on special interests, which can make mindfulness particularly beneficial but also challenging. Traditional mindfulness training that emphasizes bodily awareness or emotional exploration may not always be accessible due to alexithymia or co-occurring conditions. When adapted to suit neurodivergent needs, though, mindfulness can provide a structured way to manage anxiety, process emotions and create moments of calm.
Rather than prioritizing detachment, autistic-friendly mindfulness embraces deep focus, structured repetition and sensory engagement. Whether through stimming, mindful movement or focusing on sensory experiences, mindfulness is a powerful tool for self-care.
The key is finding what works best for you. After all, practicing mindfulness isn’t about changing who you are—it’s about creating space to feel grounded and present in a way that supports your autistic experience.

The Best Places to Live with Autism
Finding the right city to live in is a lofty task for everyone, especially autistic individuals. When considering where to plant roots, Autistic adults may want to consider things like extensive public transportation, inclusive communities, sensory-friendly environments and robust support networks. They should also think about proximity to family and friends, as well as consider any potential difficulties in coping with change before making a big move.
Thanks to inclusivity, public transportation, and advocacy groups, here are our picks for the best places for adults with autism spectrum disorder to call home.

Can Autism Be Cured? Why Acceptance Matters More
Autism is a natural variation in human neurodevelopment. Those on the autism spectrum often have unique ways of thinking, learning and interacting with the world. Autistic peoples’ brains are essentially wired differently––and many people want to find the cause of these differences and remove them. In fact, most money going toward autism research is going toward researching the treatment and prevention of autism.
However, studying the causes of autism with the intention of curing it is a controversial topic. Autism spectrum disorder is a neurodevelopmental disorder that cannot––and many argue, should not––be “cured.”

Understanding Adult Autism Statistics: What the Numbers Can (and Can't) Tell Us
Autism has gained much attention and coverage in the news recently, including reports of “rising rates” of the neurodevelopmental condition. This has caused noticeable public confusion and undue alarm about autism and what’s behind the supposed increase in diagnoses.
What’s essential to clarify is that there isn’t necessarily a sudden increase in the number of autistic people, but rather that a growing understanding of the neurotype is leading to more people getting diagnosed. And this is a good thing.
It’s also important to note that vaccination has nothing to do with the increase in autism diagnoses, as numerous studies have confirmed.
“What we mean by ‘autism’ has been evolving pretty fast in the last 30 years,” says Rachel Loftin, PhD, Chief Clinical Officer at Prosper Health. “Data from 1992 on autistic people may not fit who is autistic in 2026. Our definition has changed, more people are available to evaluate and diagnose, and the stigma has largely shifted, leading to more people seeking evaluation.”
There are a lot of autism statistics and facts out there, but they don’t all say the same thing. We also need to remember that new research is always coming out, and numbers are evolving in real time. That said, this article will walk you through what the most current numbers say, why they look the way they do, and what they mean for autistic adults.

PMDD and Autism: Understanding Their Intersection and Getting Support
No one loves getting their period––but for people with PMDD, periods can be debilitating. PMDD affects up to 10% of people who menstruate, and for autistic individuals, that rate is even higher. PMDD presents unique challenges for autistic people, but there are several options for treatment and support that can help them reduce and cope with PMDD symptoms.
