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:

 

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.

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?

Supporting Autistic People’s Unique Relationships with Food: Honoring Autonomy, Sensory Needs and Nourishment

Eating is a routine activity for most people, but for autistic individuals, it can be deeply tied to sensory experiences, autonomy and emotional well-being. Autistic people commonly face food-related challenges including sensory sensitivities, interoception differences and restricted diets.

Rather than focusing on compliance or normalizing food habits, supporting autistic people means respecting their individual relationships with food, embracing sensory needs and upholding autonomy. At the same time, it is important to consider any physical health impacts of dietary differences and discuss these with your physician in order to make an informed decision about whether you want to consider changes in order to maintain your health or prevent future health problems. You should always involve a doctor or nutritionist in any plans to make significant dietary changes, and any tips provided below have not been reviewed by a physician and are not intended to serve as medical advice.
