Fields: Neurobiology • Neuropsychology • Trauma Studies • Somatics • Relational Intelligence • Sexual Wellness • Social Function • Human Systems
Abstract
Post-Traumatic Stress Disorder (PTSD) and Complex Post-Traumatic Stress Disorder (CPTSD) are commonly understood through psychiatric and psychological diagnostic frameworks. However, trauma can also produce persistent changes in attention, perception, memory, emotional regulation, autonomic arousal, sensory processing, bodily awareness, relationships, sexuality, identity, energy regulation, and everyday functioning.
This EyeHeart Intelligence paper proposes Acquired Neurodivergency™ as a conceptual framework for examining these persistent trauma-associated differences in neurological and behavioral functioning.
The term does not propose that PTSD or CPTSD should automatically be classified as neurodevelopmental neurodivergences such as autism or ADHD. Rather, it proposes that substantial trauma may produce enduring adaptations in how a person processes information, detects threat, regulates arousal, experiences the body, relates to others, and navigates environments.
The framework therefore asks a different question:
What if some behaviors traditionally interpreted solely as dysfunction are also adaptations of a nervous system attempting to survive, predict, protect, regulate, and recover?
PTSD diagnostic criteria include intrusion/re-experiencing, avoidance, negative changes in cognition and mood, and alterations in arousal and reactivity.
CPTSD adds disturbances in self-organization, particularly affect regulation, self-concept, and relationships.
EyeHeart Intelligence proposes that these domains can be studied within a broader Trauma Adaptation Spectrum encompassing neurological, psychological, somatic, relational, sexual, energetic, occupational, and social functioning.
I. Core Definition
Acquired Neurodivergency™
Acquired Neurodivergency™ is an EyeHeart Intelligence conceptual term describing persistent differences in neurological, psychological, somatic, sensory, emotional, relational, behavioral, or functional processing that emerge or substantially change following significant environmental exposure, trauma, chronic stress, injury, illness, deprivation, or other life experiences.
The term is intentionally broader than PTSD.
It does not mean:
"Trauma makes someone defective."
It proposes:
Trauma can change the way a nervous system predicts, perceives, protects, responds, remembers, connects, and regulates.
The resulting pattern may be adaptive in the environment in which it developed but become burdensome when the environment changes.
II. PTSD and CPTSD: Clinical Foundation
PTSD commonly involves four broad DSM-5 symptom domains:
- Intrusion/re-experiencing
- Avoidance
- Negative alterations in cognition and mood
- Alterations in arousal and reactivity
Symptoms must cause clinically significant distress or impairment and persist beyond the required duration for diagnosis.
ICD-11 takes a narrower approach to PTSD, emphasizing:
- re-experiencing in the present
- avoidance
- persistent sense of threat
CPTSD incorporates those PTSD features plus disturbances in self-organization involving:
- affect regulation
- negative self-concept
- relationship functioning.
III. The EyeHeart Trauma Adaptation Model
EyeHeart Intelligence proposes seven interacting domains:
1. Neurobiological
Brain and nervous-system adaptation.
2. Neuropsychological
Attention, memory, executive functioning, perception and cognition.
3. Somatic
Body sensations, autonomic responses, pain, tension, fatigue and physiological regulation.
4. Emotional
Affect intensity, emotional numbing, shame, anger, fear and regulation.
5. Relational
Attachment, trust, intimacy, boundaries and interpersonal safety.
6. Sexual
Desire, arousal, avoidance, compulsivity, intimacy, embodiment and sexual safety.
7. Functional
Work, education, finances, self-care, organization, communication, sleep and daily living.
These domains can interact recursively.
TRAUMA → THREAT DETECTION → PHYSIOLOGICAL ACTIVATION → COGNITIVE/EMOTIONAL ADAPTATION → BEHAVIOR → RELATIONAL CONSEQUENCES → ENVIRONMENTAL FEEDBACK → FURTHER ADAPTATION
IV. Comprehensive Trauma-Associated Symptom and Functional Spectrum
The following is a comprehensive functional inventory, not a diagnostic checklist. A person may experience some, many, or none of these features.
A. Intrusion and Re-Experiencing
Possible experiences include:
- intrusive memories
- unwanted thoughts
- flashbacks
- emotional flashbacks
- trauma-related nightmares
- recurring dreams
- sensory memories
- trauma-associated smells
- trauma-associated sounds
- trauma-associated bodily sensations
- sudden emotional activation
- physiological reactions to reminders
- feeling temporarily transported back to the traumatic context
- involuntary mental imagery
- distress when encountering reminders
- anniversary reactions
- unexpected activation from seemingly unrelated stimuli
PTSD can involve re-experiencing through memories, dreams, flashbacks, thoughts, emotions, and physiological responses.
V. Hyperarousal and Threat Detection
Possible features include:
- hypervigilance
- scanning rooms
- monitoring exits
- sitting with one's back to a wall
- exaggerated startle response
- sensitivity to unexpected movement
- sensitivity to sudden sounds
- persistent sense of danger
- difficulty relaxing
- inability to "switch off"
- racing thoughts
- irritability
- anger
- aggressive impulses
- defensive reactions
- impatience
- restlessness
- muscular tension
- clenched jaw
- rapid heartbeat
- sweating
- trembling
- feeling constantly "on"
- difficulty sleeping
- difficulty staying asleep
- waking suddenly
- fragmented sleep
- nightmares
Hypervigilance, exaggerated startle, irritability, concentration problems and sleep disturbance are established PTSD-associated features.
VI. Hypoarousal, Shutdown and Dissociation
Trauma adaptation does not always look like hyperactivity.
Some people experience periods of:
- emotional numbness
- exhaustion
- shutdown
- withdrawal
- feeling disconnected
- depersonalization
- derealization
- feeling unreal
- feeling detached from one's body
- feeling like an observer
- reduced emotional responsiveness
- reduced motivation
- difficulty initiating tasks
- "blanking out"
- losing track of time
- memory gaps
- automatic behavior
- difficulty identifying emotions
- difficulty identifying bodily sensations
- inability to respond during conflict
- freezing
- collapse after prolonged stress
Dissociative experiences can occur with PTSD, although dissociation is not required for PTSD or CPTSD.
VII. Energy and Vitality
EyeHeart Intelligence proposes that trauma-related functioning should include energy regulation as an important functional domain.
Possible experiences include:
- persistent fatigue
- exhaustion after social interaction
- exhaustion after emotional conversations
- exhaustion after conflict
- exhaustion after sensory stimulation
- difficulty getting out of bed
- fluctuating energy
- sudden energy crashes
- "wired but tired" states
- inability to relax despite exhaustion
- needing unusually long recovery periods
- reduced stamina
- difficulty sustaining attention
- difficulty sustaining physical activity
- post-stress exhaustion
- daytime sleepiness
- disrupted sleep-wake rhythms
- periods of unusually high activity followed by depletion
- reduced motivation
- loss of vitality
- feeling chronically depleted
These experiences are not specific to PTSD and can have numerous medical, psychiatric, sleep-related, medication-related, and environmental causes. Trauma research nevertheless identifies substantial associations between trauma/PTSD and somatic and fatigue-related syndromes.
VIII. Cognitive and Neuropsychological Function
Possible changes include:
Attention
- distractibility
- difficulty sustaining attention
- excessive environmental monitoring
- attention captured by potential threats
- difficulty filtering background information
- difficulty switching attention
- hyperfocus on perceived danger
Memory
- intrusive memories

- fragmented memories
- difficulty retrieving information under stress
- ordinary forgetfulness
- working-memory difficulties
- losing one's train of thought
- difficulty remembering conversations
Executive Function
- procrastination
- task initiation problems
- organization difficulties
- planning difficulties
- prioritization difficulties
- decision paralysis
- difficulty transitioning between tasks
- difficulty completing tasks
- difficulty managing multiple demands
Cognitive Processing
- catastrophizing
- threat-oriented interpretation
- black-and-white thinking
- difficulty tolerating uncertainty
- persistent "what if?" thinking
- rumination
- intrusive analysis
- difficulty trusting one's judgment
- excessive checking
- difficulty processing information during stress
Concentration problems and trauma-related cognitive changes are recognized components of PTSD.
IX. Emotional Regulation
Possible manifestations include:
- intense fear
- anxiety
- panic
- anger
- rage
- irritability
- sadness
- grief
- shame
- guilt
- humiliation
- helplessness
- hopelessness
- emotional volatility
- rapid emotional shifts
- difficulty calming down
- emotional flooding
- emotional shutdown
- numbness
- difficulty identifying emotions
- difficulty expressing emotions
- feeling overwhelmed by ordinary emotions
- feeling unable to experience pleasure
- reduced positive affect
CPTSD specifically includes significant difficulties with affect regulation as part of disturbances in self-organization.
X. Self-Concept and Identity
Possible features include:
- shame
- self-blame
- excessive responsibility
- feeling defective
- feeling permanently damaged
- feeling unworthy
- feeling powerless
- feeling contaminated
- feeling fundamentally unsafe
- chronic guilt
- survivor guilt
- identity confusion
- difficulty knowing one's own preferences
- difficulty knowing what one wants
- difficulty trusting one's perceptions
- persistent self-criticism
- perfectionism
- people-pleasing
- fear of disappointing others
- difficulty recognizing personal accomplishments
Negative self-concept is one of the three principal disturbances in self-organization used in the ICD-11 CPTSD framework.
XI. Relational and Attachment Function
Possible experiences include:
- difficulty trusting others
- fear of abandonment
- fear of betrayal
- fear of intimacy
- difficulty maintaining intimacy
- social withdrawal
- isolation
- difficulty asking for help
- difficulty receiving help
- difficulty expressing needs
- difficulty saying no
- excessive compliance
- people-pleasing
- difficulty establishing boundaries
- excessive boundaries
- emotional distancing
- attachment anxiety
- attachment avoidance
- alternating closeness and withdrawal
- fear of conflict
- excessive conflict
- difficulty repairing relationships
- difficulty forgiving
- difficulty receiving affection
- difficulty giving affection
- difficulty believing someone is safe
- difficulty tolerating vulnerability
- difficulty distinguishing intimacy from danger
- difficulty feeling emotionally present
CPTSD's relationship domain specifically concerns significant difficulties sustaining relationships and emotional intimacy.
XII. Sexuality and Sexual Function
Trauma can affect sexuality in multiple and sometimes opposite directions.
Possible experiences include:
Reduced Sexual Function
- reduced libido
- loss of sexual interest
- difficulty becoming aroused
- difficulty remaining aroused
- difficulty reaching orgasm
- reduced genital sensation
- difficulty with erection
- difficulty with lubrication
- pain during sexual activity
- difficulty relaxing during intimacy
- difficulty remaining mentally present
- avoidance of sex
- fear of sexual contact
- fear of vulnerability
- difficulty trusting a partner
- difficulty experiencing pleasure
Trauma-Associated Sexual Avoidance
- avoiding dating
- avoiding romantic relationships
- avoiding physical affection
- avoiding nudity
- avoiding sexual touch
- discomfort with being observed
- discomfort with bodily exposure
- fear of losing control
- fear of being trapped
- fear of being touched unexpectedly
Hypersexual or Compulsive Patterns
For some individuals, trauma-related sexual behavior may instead involve:
- increased sexual activity
- compulsive sexual behavior
- sexual behavior used to regulate emotions
- seeking validation through sexual attention
- difficulty distinguishing intimacy from validation
- risky sexual behavior
- using sexuality to avoid emotional pain
Research indicates that PTSD can be associated with sexual dysfunction and that sexual functioning may range from sexual avoidance to compulsive or risky sexual behavior.
Importantly:
There is no single "trauma sexuality."
Trauma can produce avoidance, hypersexuality, reduced desire, increased desire, dissociation during sex, difficulty with arousal, or combinations of these patterns.
XIII. Somatic and Body-Based Experiences
Possible experiences include:
- muscle tension
- headaches
- jaw tension
- gastrointestinal distress
- nausea
- altered appetite
- sweating
- trembling
- rapid heartbeat
- shortness of breath
- chest tightness
- dizziness
- fatigue
- sleep disturbance
- bodily numbness
- heightened bodily sensitivity
- pain
- unexplained physical discomfort
- feeling disconnected from the body
- difficulty identifying hunger
- difficulty identifying thirst
- altered temperature perception
- difficulty recognizing fatigue
- heightened awareness of internal sensations
Trauma exposure has been associated with functional somatic syndromes, although somatic symptoms have many possible causes and should not automatically be attributed to trauma.
XIV. Sensory Processing
Potential trauma-associated sensory differences include:
- heightened sensitivity to sound
- heightened sensitivity to light
- sensitivity to touch
- sensitivity to smells
- sensitivity to crowds
- sensitivity to physical proximity
- discomfort with unexpected touch
- discomfort in enclosed spaces
- discomfort in chaotic environments
- heightened awareness of movement
- visual scanning
- auditory monitoring
- difficulty filtering competing stimuli
- sensory overload
- need for predictable environments
- need for controlled environments
EyeHeart Intelligence should emphasize that these experiences can overlap with neurodevelopmental neurodivergence, neurological conditions, migraine, anxiety, sleep disorders and other conditions and therefore should not automatically be attributed to trauma.
XV. Sleep
Potential effects include:
- insomnia
- difficulty falling asleep
- difficulty staying asleep
- early waking
- restless sleep
- nightmares
- trauma dreams
- waking in panic
- sleep avoidance
- fear of sleeping
- sleeping excessively
- irregular sleep schedules
- daytime fatigue
- difficulty waking
- non-restorative sleep
Sleep disturbance is a recognized PTSD symptom.
XVI. Behavior and Coping
Possible trauma-associated behaviors include:
- avoidance
- withdrawal
- isolation
- compulsive checking
- excessive preparation
- controlling environments
- perfectionism
- overworking
- procrastination
- emotional eating
- appetite changes
- substance use
- compulsive behaviors
- risk-taking
- self-sabotage
- difficulty resting
- excessive productivity
- excessive caretaking
- people-pleasing
- conflict avoidance
- conflict escalation
- fleeing situations
- freezing
- shutting down
Some behaviors may represent attempts to regulate overwhelming internal states rather than deliberate self-destructive choices.
XVII. General Functional Capacity
Trauma-associated symptoms can affect:

- testing
- executive functioning
- social engagement
Financial Function
- difficulty organizing bills
- avoidance of financial information
- impulsive spending
- difficulty planning
- difficulty maintaining employment
- financial anxiety
Social Function
- isolation
- difficulty maintaining friendships
- difficulty attending events
- avoidance of crowds
- difficulty trusting groups
- difficulty participating in community life
XVIII. Trauma and Time Perception
An underexamined dimension of trauma adaptation is the subjective experience of time.
Possible experiences include:
- feeling stuck in the past
- feeling that danger is always imminent
- difficulty imagining the future
- excessive anticipation
- living primarily in memories
- difficulty experiencing the present
- anniversary reactions
- distorted perception of how long stressful experiences lasted
- losing track of time during dissociation
- feeling that recovery is taking "forever"
This suggests an EyeHeart research question:
Does trauma alter not only what a person remembers, but how the person experiences past, present and future?
XIX. Safety Perception
One of the central concepts of the EyeHeart model should be:
The Safety-Detection System
A trauma-adapted nervous system may continuously ask:
Am I safe?
rather than:
What is happening?
This can produce:
Threat → attention → interpretation → physiological response → behavior → environmental response
A person may therefore experience ordinary circumstances through a threat-detection architecture shaped by previous experience.
The goal of trauma recovery is not necessarily to eliminate vigilance.
It may be to develop:
Flexible vigilance.
The ability to distinguish:
danger
from
uncertainty
from
discomfort
from
memory
from
actual present safety.
XX. Acquired Neurodivergency™ as an EyeHeart Concept
EyeHeart Intelligence proposes five broad categories:
A. Developmental Neurodivergency
Differences primarily associated with neurodevelopment.
B. Acquired Neurodivergency™
Persistent neurological or functional differences emerging after significant life experiences.
C. Trauma-Associated Neurodivergency
Acquired differences specifically associated with traumatic stress.
D. Injury-Associated Neurodivergency
Persistent functional differences following neurological or physical injury.
E. Environmental Neurodivergency
Functional differences produced or amplified by sustained environmental conditions.
These categories are conceptual rather than established diagnostic classifications.
XXI. Adaptation Rather Than Defect
EyeHeart Intelligence proposes replacing the simplistic question:
"What's wrong with this person?"
with:
"What happened, what did the nervous system learn, what function did the adaptation serve, and is that adaptation still necessary?"
For example:
Hypervigilance
may once have increased safety.
Avoidance
may once have reduced exposure to danger.
Emotional numbing
may once have reduced overwhelming emotional pain.
People-pleasing
may once have reduced interpersonal conflict.
Dissociation
may have helped a person psychologically distance themselves from overwhelming circumstances.
Perfectionism
may have become an attempt to control unpredictable outcomes.
The adaptation can therefore be understood without romanticizing or endorsing the symptom.
XXII. The Double-Edged Adaptation Principle™
EyeHeart Intelligence proposes:
An adaptation can be simultaneously protective, understandable, costly and changeable.
This prevents two extremes:
Pathologization
"Your response is abnormal."
Romanticization
"Your trauma response is your superpower."
Instead:
Your response may have made sense. You deserve to understand it. And you deserve the opportunity to develop new choices.
XXIII. Functional Neurodiversity and Environmental Fit
EyeHeart Intelligence further proposes that impairment may arise from the interaction between:
PERSON × NERVOUS SYSTEM × ENVIRONMENT × EXPECTATIONS
A trauma-adapted person may function extremely well in one environment and poorly in another.
For example:
A high-alert nervous system may perform well in an emergency but become exhausted by a chaotic workplace.
A person who requires predictability may function well with clear expectations but struggle under constantly changing rules.
A person with strong threat detection may identify genuine danger rapidly but also experience false alarms.
This introduces the concept of:
Trauma-Environment Fit™
The question becomes not merely:
"Can this person function?"
but:
"Under what environmental conditions does this person's nervous system function best?"
XXIV. Recovery as Neuroadaptation
If trauma can produce persistent adaptation, recovery can involve developing new adaptation.
Potential goals include:
- increased nervous-system flexibility
- improved emotional regulation
- improved sleep
- restored bodily awareness
- increased sense of safety
- improved executive functioning
- improved relationships
- restored sexuality and intimacy
- healthier boundaries
- reduced avoidance
- increased capacity for pleasure
- improved self-concept
- greater ability to tolerate uncertainty
- increased ability to distinguish present safety from past danger
- expanded behavioral choice
Recovery should therefore not be conceptualized simply as:
"return to who you were."
It can also mean:
developing who you are after what happened.
XXV. Clinical and Scientific Guardrails
The EyeHeart Intelligence framework should explicitly acknowledge that:
- Acquired Neurodivergency™ is a proposed conceptual term, not an established medical diagnosis.
- PTSD is a recognized clinical diagnosis.
- CPTSD is recognized in ICD-11 but is not a separate DSM-5 diagnosis.
- Not every symptom listed in this paper is diagnostic of PTSD or CPTSD.
- Many symptoms have multiple possible causes.
- Physical symptoms should not automatically be attributed to trauma.
- Neurodevelopmental conditions and trauma-related conditions can coexist.
- Brain injury, neurological illness, endocrine disorders, sleep disorders, medication effects and substance use can produce overlapping symptoms.
- Sexual symptoms can have psychological, relational, physiological, hormonal, medication-related and other causes.
- A qualified clinician should make diagnostic determinations.

XXVII. The Central EyeHeart Proposition
Trauma is not merely something that happened to the mind.
It can affect the:
brain, nervous system, body, attention, memory, emotions, sensory processing, sexuality, relationships, identity, energy regulation, behavior and capacity to participate in ordinary life.
Accordingly:
A trauma-informed understanding of human behavior must examine the whole person rather than reducing the person to a diagnosis.
EyeHeart Intelligence calls this approach:
Whole-Person Trauma Intelligence™
Neurobiology + Neuropsychology + Somatics + Emotion + Relationship + Sexuality + Identity + Environment + Function
XXVIII. Closing Statement
PTSD and CPTSD should not be understood solely as collections of symptoms.
They can also be understood as complex patterns of adaptation involving a human nervous system attempting to navigate a world after experiences that altered its expectations of safety.
The concept of Acquired Neurodivergency™ provides EyeHeart Intelligence with a language for investigating those persistent differences without prematurely defining them as either pathology or identity.
The central question becomes:
How has experience changed the way this person processes the world—and what environments, relationships, knowledge, resources and interventions could help that person regain flexibility, agency, safety, dignity and connection?
This is the foundation of the EyeHeart Intelligence Trauma Adaptation Framework™.
See differently.
Understand deeply.
Respond intelligently.
Restore human possibility.
Research Note
This framework is intended for education, research, conceptual development and trauma-informed systems design. It is not a substitute for professional diagnosis or treatment. The symptom inventory intentionally extends beyond formal diagnostic criteria to capture functional domains that may be clinically relevant but are not themselves diagnostic requirements.
