Understanding Neurodivergent Conditions
Clear, validating explanations of ADHD, autism, SPD, ARFID, PDA, RPR, OCD, PTSD, and AUDHD. These are not disorders to be fixed—they're different ways of being that deserve understanding and support.
ADHD
Attention-Deficit/Hyperactivity Disorder
ADHD is a neurodevelopmental condition that affects executive function, attention regulation, and impulse control. It's not about 'trying harder'—it's about how your brain processes dopamine and regulates attention. ADHD brains are interest-based, not importance-based.
Key Insight
ADHD is not a deficit of attention—it's inconsistent attention regulation. You're not lazy or unmotivated; your brain needs different systems and strategies.
Common Signs & Experiences
- •Difficulty sustaining attention on tasks that aren't immediately rewarding
- •Time blindness (losing track of time, struggling with deadlines)
- •Executive dysfunction (trouble starting tasks, planning, organizing)
- •Emotional dysregulation (intense emotions, quick to frustration)
- •Hyperfocus on topics of interest
- •Forgetfulness, losing things frequently
- •Restlessness or constant need for movement (hyperactivity)
- •Impulsivity (interrupting, making quick decisions without thinking)
Often Co-Occurs With
Autism (ASD)
Autism Spectrum Disorder
Autism is a neurological difference that affects how you process information, communicate, and experience the world. Autistic brains are detail-oriented, pattern-seeking, and often highly sensitive to sensory input. Autism is a spectrum, meaning it presents differently in every person.
Key Insight
Autism is not a disorder to be fixed—it's a different operating system. Unmasking and accommodating your needs is not 'giving up'; it's self-preservation.
Common Signs & Experiences
- •Difficulty with social communication (reading social cues, small talk)
- •Preference for routine and predictability; distress with unexpected changes
- •Intense, focused interests (special interests or hyperfixations)
- •Sensory sensitivities (sounds, lights, textures, smells)
- •Stimming (repetitive movements like hand-flapping, rocking, fidgeting)
- •Masking (hiding autistic traits to 'fit in,' leading to burnout)
- •Literal thinking, difficulty with abstract language or sarcasm
- •Need for alone time to recharge after social interaction
Often Co-Occurs With
AUDHD
Autism + ADHD
AUDHD (also called AuDHD) is the co-occurrence of autism and ADHD. These two conditions can create internal contradictions—craving routine but also novelty, needing alone time but also stimulation. AUDHD brains are complex, and strategies need to honor both sides.
Key Insight
AUDHD is not 'mild autism' or 'mild ADHD'—it's both conditions fully present, creating unique challenges and strengths. You're not contradictory; you're complex.
Common Signs & Experiences
- •Need for routine AND novelty (the 'AUDHD paradox')
- •Hyperfocus on special interests but difficulty with executive function
- •Social exhaustion but also craving connection
- •Sensory sensitivities combined with impulsivity
- •Masking autistic traits while managing ADHD symptoms
- •Burnout from trying to meet conflicting needs
Often Co-Occurs With
SPD
Sensory Processing Disorder
SPD affects how the nervous system processes sensory information (touch, sound, sight, taste, smell, movement, body awareness). People with SPD may be over-responsive (sensory-sensitive), under-responsive (sensory-seeking), or a mix of both.
Key Insight
SPD is not 'being dramatic' or 'overreacting'—it's a real nervous system difference. Accommodations like noise-canceling headphones or weighted blankets aren't 'giving in'; they're necessary support.
Common Signs & Experiences
- •Over-responsiveness: Overwhelmed by loud noises, bright lights, certain textures, strong smells
- •Under-responsiveness: Seeking intense sensory input (spinning, crashing, chewing)
- •Difficulty with clothing tags, seams, certain fabrics
- •Avoidance of messy play, certain foods due to texture
- •Meltdowns or shutdowns in overstimulating environments
- •Poor body awareness (proprioception) or balance issues
Often Co-Occurs With
ARFID
Avoidant/Restrictive Food Intake Disorder
ARFID is an eating disorder characterized by extremely limited food intake due to sensory sensitivities, fear of aversive consequences (choking, vomiting), or lack of interest in eating. It's not 'picky eating'—it's a nervous system response.
Key Insight
ARFID is not 'just being picky' or 'seeking attention'—it's a real eating disorder rooted in sensory processing and anxiety. Forcing food makes it worse; gradual, low-pressure exposure helps.
Common Signs & Experiences
- •Eating only a very limited range of 'safe foods' (often 5-15 foods)
- •Anxiety or distress when presented with new foods
- •Gagging, vomiting, or panic when trying unfamiliar textures or flavors
- •Avoidance of social eating situations
- •Nutritional deficiencies or weight loss due to restricted intake
- •Sensory-based food refusal (texture, smell, appearance)
Often Co-Occurs With
PDA
Pathological Demand Avoidance (Autism Profile)
PDA is a profile of autism characterized by extreme anxiety-driven avoidance of everyday demands. It's not defiance or willfulness—it's a nervous system response to perceived loss of control. Traditional parenting strategies (rewards, consequences, firm boundaries) often backfire with PDA.
Key Insight
PDA is not 'bad behavior'—it's an anxiety-driven nervous system response. Low-demand parenting, offering choices, and indirect language reduce anxiety and improve cooperation.
Common Signs & Experiences
- •Intense resistance to everyday requests (even preferred activities)
- •Anxiety escalates when demands are placed
- •Need for control and autonomy
- •Social masking (appearing 'fine' in public, melting down at home)
- •Difficulty with direct instructions; responds better to indirect approaches
- •Avoidance strategies (negotiating, distracting, refusing)
Often Co-Occurs With
RPR
Retained Primitive Reflexes
Primitive reflexes are automatic movement patterns present in infancy that should integrate (disappear) as the nervous system matures. When these reflexes are retained past early childhood, they can affect coordination, focus, emotional regulation, and learning.
Key Insight
RPR is often overlooked but can significantly impact development. OT-backed reflex integration exercises can improve coordination, focus, and emotional regulation.
Common Signs & Experiences
- •Poor balance and coordination
- •Difficulty with fine motor skills (handwriting, buttoning)
- •Trouble sitting still, constant fidgeting
- •Sensitivity to light, sound, or touch
- •Difficulty crossing the midline (using both sides of the body together)
- •Emotional dysregulation, anxiety, or impulsivity
- •Learning challenges (reading, writing, math)
Often Co-Occurs With
OCD
Obsessive-Compulsive Disorder
OCD is a mental health condition characterized by intrusive, unwanted thoughts (obsessions) and repetitive behaviors or mental rituals (compulsions) performed to reduce anxiety. It's not about being 'neat' or 'organized'—it's about being trapped in anxiety loops your brain can't escape.
Key Insight
OCD is not about being 'particular' or 'perfectionistic'—it's a real anxiety disorder. Exposure and Response Prevention (ERP) therapy and nervous system regulation strategies are key to managing OCD.
Common Signs & Experiences
- •Intrusive, distressing thoughts that won't go away
- •Compulsive behaviors (checking, counting, washing, arranging)
- •Mental rituals (repeating phrases, reassurance-seeking)
- •Extreme anxiety if rituals are interrupted
- •Fear of contamination, harm, or 'bad things' happening
- •Need for symmetry, order, or 'just right' feelings
- •Time-consuming rituals that interfere with daily life
Often Co-Occurs With
PTSD
Post-Traumatic Stress Disorder
PTSD is a mental health condition that develops after experiencing or witnessing a traumatic event. For neurodivergent individuals, PTSD can be particularly complex—trauma responses may be misattributed to autism or ADHD traits, and sensory sensitivities can intensify trauma symptoms. Many late-diagnosed adults experience trauma from years of masking, misunderstanding, and feeling 'wrong.'
Key Insight
PTSD in neurodivergent individuals is often overlooked or misdiagnosed. Trauma-informed care that honors your neurodivergence—not forcing eye contact, respecting sensory needs, understanding meltdowns vs. flashbacks—is essential for healing.
Common Signs & Experiences
- •Intrusive memories, flashbacks, or nightmares about the traumatic event
- •Hypervigilance (constantly scanning for danger, easily startled)
- •Avoidance of triggers (places, people, situations that remind you of trauma)
- •Emotional numbness or disconnection from feelings
- •Difficulty trusting others or feeling safe
- •Intense anxiety, panic attacks, or emotional dysregulation
- •Sleep disturbances, nightmares, or insomnia
- •Physical symptoms (racing heart, sweating, trembling) when triggered
