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.
How to Get Tested for Autism as an Adult: A Comprehensive Guide
Have you ever thought about getting tested for autism?
Perhaps because, as both a child and an adult, you’ve always felt misunderstood or out of sync with your peers. You could never quite put your finger on why you were different, but deep down, you knew there had to be an underlying reason. As our collective understanding of autism and diverse neurotypes grows, more and more people are realizing their autism might have been missed when they were kids and are now seeking a diagnosis in adulthood.
The day we received my daughter’s autism diagnosis, it felt like the world finally opened its doors to our family. But so many autistic individuals have lived their entire lives without knowing they are neurodivergent, and as a result, aren’t getting the support they need. Luckily, it’s never too late to get an autism diagnosis, but the process can feel intimidating. Where do you even start? Especially when autism testing options for adults, as well as data on autistic adults, are still relatively limited.
For example, the Centers for Disease Control estimates that 1 in 45 adults in the United States is autistic, but many are undiagnosed.
The good news is that there is growing recognition of the need for more accessible and respectful autism assessments and diagnoses. This has led to a push to improve the overall autism testing process for adults in recent years. According to a study published in JAMA Network Open, the rate of diagnosis in young adults (age range: 26-34) rose 450% between 2011 and 2022.
Getting yourself tested for autism can feel like an overwhelming task. That’s why Prosper Health is here to provide you with a step-by-step, supportive guide that will give you everything you need to know about the diagnostic process, from self-reflection to post-diagnosis support and resources.

Navigating Autism and Communication Differences in Adults: Strategies for Success
To be diagnosed with autism spectrum disorder, an individual must have social and communication differences compared to those without autism, and those differences must impact their daily life. The severity varies from one individual to the next. However, communication differences are a core characteristic of autism.
Common challenges faced by autistic people include:
- Difficulty interpreting or understanding body language
- Difficulty modulating tone, volume or speed of speech
- Trouble understanding idioms, figurative language or other instances of non-literal speech
- Uncertainty during social interaction
- Using more direct language or more formal and technical language, which is sometimes mistakenly interpreted as “bluntness” or “rudeness”
- Using repeated words or phrases (or echolalia)
- Having a flat affect or appearing uninterested during conversations, even if they are engaged
Differences in communication between autistic individuals and non autistic individuals often lead to difficulties for the autistic population. These difficulties include:
- Facing judgment during social situations or bullying from peers
- Finding it hard to make or maintain friendships
- Developing anxiety around social situations
- Feeling fatigued after a social interaction
- Increased risk of isolation or loneliness
- Low self-esteem or negative self-image
- Engaging in masking behaviors, which can lead to burnout
When communication style differences are judged instead of accommodated, it leads to negative outcomes for autistic individuals. Support and resources can help autistic individuals become more effective communicators, but that’s only one piece of the puzzle. It’s also important that we learn to not only understand autistic communication but also accept and embrace it.

Autism and Trauma: How They Intersect and How to Manage Trauma-Related Stress
For many people, fully understanding an autism diagnosis means unpacking their relationship to trauma. This was true for me after I was diagnosed with both autism spectrum disorder (ASD) and complex post-traumatic stress disorder (CPTSD) in my late twenties.
Many autistic people experience trauma, which can affect them in distinct ways compared to neurotypical peers. For these individuals, digging into the relationship between autism and trauma can make a profound difference in regulating their nervous systems and improving their mental health. For me, my autism and CPTSD diagnoses have been equally revelatory and often intertwined. Exploring the relationship between the two has helped me better understand myself and tangibly improve my quality of life.
Read on to learn about the link between autism and trauma-related disorders, as well as how to cope.

How to Manage PDA: A Guide for Autistic Adults
Does the thought of day-to-day chores make you feel paralyzed? Does your phone pile up with unread emails and unanswered texts you can’t make yourself respond to? There are many reasons why people might struggle to meet the demands of daily living, but for those who identify with the experiences associated with pathological demand avoidance, all demands can feel oppressive and anxiety-inducing.
Sometimes called pervasive drive for autonomy, PDA is a behavioral profile most commonly associated with autism spectrum disorder (ASD). PDA is said to be different from simply disliking certain tasks or being asked to do something. It’s natural for people to put off or avoid certain demands—however, some individuals experience a more intense and pervasive drive for agency and resistance to demands, which can impact their daily lives and mental health.
PDA was first proposed as a unique subtype of autism spectrum disorder, but is now most often understood as a possible profile of autism, meaning a pattern of behaviors and traits present in some autistic people. To date, researchers have yet to reach a consensus on how to categorize PDA or on its definition, characteristics and support strategies. PDA advocacy, however, has grown as a field, and advocates have advanced many recommendations for support based on PDA individuals’ lived experiences.
If the proposed PDA autism behavioral profile resonates with you, read on for tips to manage it.

Mastering ACCEPTS: A Guide for Autistic Adults to Dialectical Behavior Therapy Skills
Dialectical behavioral therapy (DBT) teaches practical tools for managing emotions and coping with distress. While it was originally developed to help those with borderline personality disorder (BPD), people who are neurodivergent or dealing with many mental health conditions can find DBT-based tools helpful.
For many adults with autism spectrum disorder, the DBT skill “ACCEPTS” is helpful during moments of sensory overload, executive functioning fatigue or emotional dysregulation. It offers simple ways to shift focus and make space to regulate before taking action.
Let’s take a closer look at what each part of ACCEPTS means and how you can make it work for you.

Navigating Autism and Anxiety: Understanding the Unique Challenges Faced by Autistic Adults
It’s normal to feel anxious sometimes—but what if anxiety gets in the way of your day-to-day life? For nearly half of autistic people, severe anxiety disorders are a reality. Anxiety disorders come with psychological and physical symptoms that can be distressing and even make it difficult to function every day. For an autistic person, they can make common stressors like sensory and social stress even harder to manage. Understanding the relationship between autism and anxiety can help an autistic adult better understand themself and get support that makes a difference.

Is There a Rise in Autism? Understanding the Trends and Implications
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by communication and social differences, strict adherence to routine and intense, narrow interests. No two autistic individuals are exactly alike, and autistic traits and severity vary from person to person.
Diagnosis of ASD is clinical, based on standardized criteria that require persistent differences in social communication and at least two types of restricted behaviors. No blood test or neurological imaging can detect or diagnose autism. Instead, developmental history and behavioral observations are part of the assessment.
ASD is usually identified in early childhood, but many autistic individuals aren’t diagnosed until adulthood. This doesn’t mean that autistic traits weren’t present during their childhood. Rather, it means they didn’t have access to the appropriate diagnostic care or didn’t fit in with outdated stereotypes of autistic behavior.
As our understanding of autism spectrum disorder changes and deepens, practitioners are getting better at accurately diagnosing those who would’ve previously gone undiagnosed or misdiagnosed in the past. As both knowledge and diagnostic criteria expand, the number of autistic individuals in the world naturally increases.
This increase has led to renewed conversations around autism. What causes it? Why is everyone autistic all of a sudden? How can we prevent it? (Although prevention should never be the goal.)
But, perhaps we’re asking the wrong questions. Maybe we should start here instead: Is there actually a rise in autism?
