Autism In AdultHood
Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are two neurodevelopmental conditions often associated with childhood.
However, as more research sheds light on the intricacies of these conditions, it becomes increasingly clear that they persist into adulthood, shaping the lives of those affected in very diverse and still undetected ways.
For adults navigating the complexities of ADHD and autism, life can feel like an unending series of puzzles where somehow everyone knows how to navigate except you.
The features of these conditions in adulthood are often misunderstood, underdiagnosed, or misdiagnosed, making awareness and understanding all the more critical..
The Overlapping Spectrum
One of the most fascinating aspects of ADHD and autism is the overlap in their characteristics, leading many to view them as part of a broader neurodivergent spectrum.
While each condition has distinct diagnostic criteria, their shared traits—such as difficulties with executive functioning, sensory sensitivities, and challenges in social interactions—often blur the lines. For instance, an adult with ADHD might struggle with impulsivity and restlessness, while someone with autism may experience rigidity in routines and heightened sensory perceptions. Yet, both individuals might find themselves overwhelmed in environments that demand sustained attention or rapid adaptability.
Scientific studies have revealed that approximately 20-50% of individuals with ADHD also meet the criteria for autism, and vice versa. This high rate of co-occurrence underscores the need for clinicians to adopt a more holistic approach when diagnosing and treating neurodivergent individuals. Misdiagnoses can lead to inadequate support, leaving adults to grapple with challenges they cannot fully articulate or address.
The interplay between genetics and environmental factors is a cornerstone of this discussion. Genes are not static; they can undergo mutations and repairs influenced by various environmental exposures, including sunlight. Ultraviolet (UV) radiation from the sun can cause DNA damage, leading to gene breakages. The body possesses mechanisms, such as nucleotide excision repair (NER), to correct this damage.
Interestingly, the efficiency of DNA repair processes is modulated by circadian rhythms—the body's internal clock. Research indicates that the time of day influences the skin's ability to repair UV-induced DNA damage, with repair activities peaking at certain times.
Exposure to sunlight also plays a pivotal role in regulating circadian rhythms. Morning sunlight, rich in blue light, helps synchronize the circadian clock, enhancing alertness and mood. Evening sunlight, with its reddish hues, signals the approach of night, promoting the release of melatonin—a hormone that facilitates sleep.
These DNA breakages contribute to the manifestation of ADHD/Autism in Individuals.
Dopamine Pathways and Their Role
The human brain is a symphony of chemical and electrical signals that govern behavior, thought, and emotion. Among the most significant players in this orchestra are neurotransmitters like dopamine and norepinephrine (noradrenaline). These chemicals are critical to attention, motivation, emotional regulation, and executive functioning—areas often affected in Attention-Deficit/Hyperactivity Disorder (ADHD).
The Role of Dopamine and Norepinephrine in ADHD.
Dopamine is a neurotransmitter central to reward, motivation, and pleasure, while norepinephrine is critical to focus, vigilance, and stress response.
Although the exact mechanisms of ADHD are not yet fully understood, reduced levels of dopamine and norepinephrine in certain brain regions are strongly implicated.
This deficiency affects pathways like:
Mesolimbic Dopamine Pathway: This pathway connects the ventral tegmental area (VTA) to the nucleus accumbens and is crucial for reward processing and motivation. A dysfunction here may explain why individuals with ADHD struggle with sustained attention or motivation for tasks that don’t provide immediate rewards.
Locus Coeruleus System: The locus coeruleus is the brain's primary source of norepinephrine. This system modulates stress responses and executive functions such as decision-making, impulse control, and working memory. Reduced norepinephrine activity here can contribute to difficulties in maintaining focus and regulating emotions.
Structural Brain Differences in ADHD
Brain imaging studies have revealed that certain regions of the brain are smaller or less active in individuals with ADHD, further shedding light on its underlying mechanisms:
Anterior Cingulate Cortex (ACC): This area plays a critical role in error detection, decision-making, and emotional regulation. A smaller ACC in individuals with ADHD may contribute to difficulties in assessing priorities and maintaining goal-directed behavior.
Dorsolateral Prefrontal Cortex (DLPFC): The DLPFC is involved in executive functions like planning, organization, and working memory. Deficits in this region can explain why individuals with ADHD often struggle to complete tasks, especially when they are not inherently engaging.
These structural differences help explain why external motivation—such as a clear reward—often works better for individuals with ADHD. Finding activities that are intrinsically enjoyable can also be a powerful tool for maintaining focus and productivity.
Medications
The dopamine and norepinephrine systems act as highways of communication in the brain.
When these pathways are functioning optimally, signals flow smoothly, enabling focus, motivation, and emotional balance.
In ADHD, however, these highways are underutilized due to lower levels of these neurotransmitters. Medications like amphetamines and methylphenidate act as traffic controllers, either increasing the flow of signals or ensuring they linger longer in transit.
Amphetamines (e.g., Adderall)
Amphetamines stimulate the release of dopamine and norepinephrine from their storage vesicles in neurons.
This surge in neurotransmitter levels enhances signaling in brain regions responsible for attention, motivation, and impulse control.
By amplifying dopamine release, amphetamines provide the brain with more robust reinforcement signals, making tasks more engaging and rewarding.
Methylphenidate (e.g., Ritalin, Concerta)
Methylphenidate acts as a reuptake inhibitor for both dopamine and norepinephrine. This means it prevents the brain from reabsorbing these neurotransmitters too quickly, leaving more available in the synaptic cleft (the space between neurons).
This sustained presence of dopamine and norepinephrine improves the brain's ability to maintain focus, regulate emotions, and respond to tasks requiring sustained effort.
Motivation
For individuals with ADHD, deficits in dopamine and norepinephrine can make mundane tasks feel nearly impossible. However, the brain's reward system can still be leveraged by aligning tasks with personal interests or by finding intrinsic meaning in them.
Here’s why this matters:
Goal-Directed Behavior: The anterior cingulate cortex and dorsolateral prefrontal cortex deficits mean that external rewards or immediate gratification are often necessary to stay engaged. This explains why individuals with ADHD can focus intensely (a phenomenon called hyperfocus) on activities they genuinely enjoy.
Intrinsic Motivation: Activities that align with an individual’s passions can override the dopamine deficit, making tasks feel effortless and rewarding. Even if the activity isn’t meaningful to others, its personal significance can fuel engagement
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), categorizes ADHD into distinct presentations: Inattentive, Hyperactive/Impulsive, or Combined. These categorizations are based on observable patterns of behavior may be viewed from an evolutionary or functional perspective.
DSM-5
Inattentive Presentation
The DSM-5 defines inattentiveness as difficulty sustaining attention, making careless mistakes, not listening when spoken to directly, being easily distracted, and struggling with organization. While these traits are typically framed as deficits, they might also be seen as adaptive mechanisms.
Being "easily distracted" could be the brain’s way of staying alert to environmental changes, a crucial survival mechanism for early humans. Your mind’s tendency to wander might reflect a powerful ability to process multiple inputs simultaneously. This capacity for mental exploration allows you to see possibilities others might overlook.
When you lock in on something that genuinely engages you, the level of focus you achieve is unparalleled.
It’s also worth considering the context of what’s called inattentiveness. Often, it’s not that you’re incapable of paying attention—it’s that the material or environment isn’t stimulating enough to hold your focus. Your brain thrives on engagement and seeks meaningful challenges. In many ways, this is a sign of a powerful, evolved mind refusing to settle for monotony.
Hyperactive/Impulsive Presentation
Hyperactivity and impulsivity are often described as excessive movement, fidgeting, squirming, getting up frequently, or acting without thinking. From a societal perspective, these traits might seem disruptive, but when viewed through a different lens, they tell a story of energy, efficiency, and a brain wired for action.
Who wants to sit forever, anyway?
Getting up and moving around might not be a sign of a problem—it could be a clear indication that your brain craves stimulation. In adulthood, hyperactivity might manifest more subtly, like zoning out of conversations or mentally "skipping ahead" because you’ve already pieced together the conclusion. While this might frustrate others, it’s also an evolutionary mechanism: your brain optimizes for efficiency by jumping straight to the point.
Impulsivity, often seen as a liability, can also be a superpower.
The ability to shorten the gap between acquiring knowledge and executing it is nothing short of extraordinary. This immediacy enables you to translate ideas into actions before overthinking interferes. It’s a trait that can drive innovation and decisiveness. You’re wired to act, and that action can lead to remarkable results when channeled effectively.
The Role of Energy and Engagement
At its core, ADHD can be seen from the perspective of energy management. Your brain is a power machine, constantly seeking input that excites and challenges it. When you provide it with engaging tasks, it rewards you with focus, creativity, and a sense of fulfillment. It thrives when you allow it to "tuffle"—to wrestle with complex problems and ideas.
When you stop fighting these tendencies and instead embrace them, you unlock a wellspring of productivity and satisfaction. It’s about learning to work with your brain instead of against it. For example, hyperfocus, often considered a hallmark of ADHD, allows you to dive deeply into topics you’re passionate about, achieving a level of mastery that others might find hard to replicate.
Masking
Many adults with ADHD or autism develop coping mechanisms to navigate societal expectations. This often takes the form of masking—a conscious or unconscious effort to hide symptoms and blend in with neurotypical peers. Masking can involve suppressing stimming behaviors, mimicking social norms, or overcompensating for perceived deficits. While masking can help individuals succeed in professional or social settings, it comes at a significant cost.
For adults, the toll of masking often manifests as burnout, anxiety, and depression. The energy required to maintain a facade of normalcy can be exhausting, leaving little room for authentic self-expression. Women, in particular, are more likely to engage in masking, contributing to their underdiagnosis in both ADHD and autism. Their symptoms often present differently than those in men, further complicating the diagnostic process. For instance, a woman with ADHD may be perceived as simply disorganized or emotional, while her autistic counterpart might be labeled as shy or overly meticulous.
The concept of 'normal' behavior is inherently fluid, shaped by cultural, societal, and evolutionary factors.
As humans evolve, so do our genetic makeups and behaviors. Epigenetics—the study of changes in gene expression without altering the DNA sequence—demonstrates that environmental factors can influence gene activity. Lifestyle choices, stress, and exposure to sunlight can lead to epigenetic modifications, resulting in diverse behavioral expressions.
Energy management emerges as a crucial aspect of navigating these behavioral expressions. Understanding one's unique neurobiological makeup allows for the development of personalized strategies to optimize daily functioning. For instance, individuals with ADHD or ASD might benefit from tailored routines that align with their circadian rhythms, incorporating morning sunlight exposure to enhance focus and evening routines that promote relaxation and sleep
Executive Functioning
At the heart of both ADHD and autism lies a shared struggle with executive functioning—the cognitive processes that enable planning, organization, and goal-directed behavior. For adults, this struggle can permeate every aspect of life, from managing finances to maintaining relationships. An adult with ADHD might find themselves perpetually late, misplacing important documents, or impulsively quitting jobs. On the other hand, an autistic adult may excel in certain structured environments but feel paralyzed when faced with unexpected changes or ambiguous tasks.
The challenges of executive dysfunction are compounded by societal expectations of independence and productivity. Adults are often expected to juggle multiple responsibilities seamlessly, yet for those with ADHD or autism, even seemingly simple tasks can feel insurmountable. Without adequate support, these individuals are at a higher risk of unemployment, financial instability, and social isolation.
Adaptive Abilities
How to Take Control of Your Adaptive Functioning Capacities
Adaptive functioning is your ability to manage daily life in a way that aligns with your goals, relationships, and well-being. To truly master it, you must start by exploring the root causes of recurring patterns in your life and learn to regulate both your inner world and your external environment.
How Are You Spending Your Free Time?
What occupies your moments of leisure? Are you doom-scrolling through endless social media feeds, chasing a dopamine hit that never truly satisfies? Or are you investing your energy in meaningless side-quests for others, driven by people-pleasing tendencies that leave you drained and unfulfilled?
This constant busyness—being busy doing nothing—may be a distraction from deeper truths. What are you avoiding? Take an hour a day to be still. Sit with your thoughts. Let them unfold, no matter how uncomfortable they may seem. In this stillness, patterns emerge: the same problems cropping up year after year, person after person, and business after business. These are the echoes of unresolved issues within you.
The wisdom of Abd Allah reminds us, "You do not have to leave your present place to get rid of a problem; in fact, if you do, you’ll find that the problem is the first one to greet you when you arrive at your journey’s end." This timeless truth points to the futility of external escape when the roots of your struggles are internal. The journey begins with you.
How Are You Caring for Yourself?
Self-care is more than fleeting indulgences; it’s a foundation for adaptive functioning. Start with the basics:
Hygiene: Are you consistent with your dental, skin, and body care?
Health: Are your eyes and ears getting proper attention? How about your feet—those humble heroes that carry you through life?
Living Space: Is your environment clean and organized, a space that nurtures rather than drains you?
Finances: Are you managing your resources responsibly, or are they slipping through your fingers unnoticed?
Relationships: Are they nourishing, or do they leave you feeling depleted?
When your external world is in disarray, it often reflects inner chaos. Start small but be deliberate. Treat yourself with the kindness you’d offer a friend in need. Like yourself enough to take actions that align with self-respect.
How Are You Managing Your Emotions?
Emotional regulation is a cornerstone of adaptive functioning. For some, society is forgiving when they fail to manage their emotions, offering grace for their outbursts or disproportionate reactions. But for others, particularly those who do not fit societal norms, this grace is harder to come by.
This means you must take ownership of your emotional landscape.
The symptoms of emotional dysregulation often include:
Intense reactions that don’t align with the situation (e.g., tantrums or crying when others remain unaffected).
Feeling overwhelmed or frustrated by trivial tasks.
"Crashing out"—a total emotional or physical shutdown.
To navigate this, develop an emotional regulation toolkit:
Pause Before Reacting: When emotions surge, take a moment. Breathe deeply and assess the situation. Ask yourself, Is my response proportional?
Identify Triggers: Over time, notice patterns in what sets you off. Understanding these triggers allows you to address root causes rather than symptoms.
Healthy Outlets: Channel your emotions into creative or physical activities. Whether it’s writing, painting, running, or yoga, movement can help you process what words cannot.
Practice Self-Compassion: When you stumble, don’t berate yourself. Treat your setbacks as opportunities for growth, not evidence of failure.
Building a Life You Want to live is about creating a life that feels balanced and fulfilling. It is about learning to manage the gap between your internal world and external expectations.
Start by answering these questions honestly:
What patterns in my life are holding me back?
How can I care for myself better?
How can I harness my emotions rather than let them control me?
The answers to these questions will illuminate the path forward. As you walk this path, remember to be gentle with yourself. Growth is a process, not an event. Each small step you take builds the capacity to live a life that feels authentic, meaningful, and, most importantly, truly your own.
Sensory Sensitivity
Adults with autism often report heightened sensitivities to lights, sounds, textures, or smells, making everyday environments overwhelming. Meanwhile, adults with ADHD may seek out sensory stimulation, such as tapping their feet or listening to music while working, to maintain focus. These sensory needs can significantly impact an individual’s quality of life, influencing everything from clothing choices to career paths.
In professional settings, sensory challenges can be particularly debilitating. The hum of fluorescent lights, the chatter of coworkers, or even the texture of a uniform can become sources of constant discomfort. Unfortunately, these struggles are rarely visible to others, leading to misunderstandings and judgments about an individual’s capabilities or commitment.
Relationships and Social Dynamics
Navigating relationships is a complex endeavor for any adult, but for those with ADHD or autism, it can be especially challenging. Social communication differences are a core aspect of autism, often leading to misunderstandings, difficulty interpreting nonverbal cues, or challenges in forming and maintaining friendships. Adults with ADHD, meanwhile, may struggle with impulsivity, forgetfulness, or difficulty listening attentively, all of which can strain relationships.
Despite these challenges, many neurodivergent adults bring unique strengths to their relationships. Their honesty, loyalty, and deep passions can foster meaningful connections. However, societal norms and expectations often fail to accommodate the diverse ways in which neurodivergent individuals express themselves, leading to feelings of alienation or rejection.
While much of the discourse around ADHD and autism focuses on challenges, it is equally important to celebrate the strengths and contributions of neurodivergent individuals. Adults with ADHD are often highly creative, resilient, and resourceful, capable of thinking outside the box and tackling problems with unique perspectives. Similarly, autistic adults frequently possess exceptional attention to detail, deep expertise in their areas of interest, and unwavering dedication to their values.
These strengths are increasingly recognized in fields such as technology, arts, and sciences. Companies that embrace neurodiversity are finding that their employees’ unique approaches to problem-solving can drive innovation and success. For example, the tech industry has begun to actively recruit autistic individuals for roles in coding and data analysis, where their skills shine.
