Understanding the Neurobiology of Trauma
A comprehensive research resource on the neurobiological impacts of childhood sexual abuse, exploitation, and trauma on developing brains.
Global Impact & Statistics

Reports of GAI-related CSAM in 2024-2025 (up from 6,835)
Missing children cases assisted by NCMEC in 2024 (91% recovered)
Cortisol Dysregulation
Excessive or prolonged stress from childhood sexual abuse dysregulates the HPA axis, the body's primary stress response system. Research demonstrates that children who develop PTSD following sexual abuse exhibit lower morning serum cortisol levels compared to non-PTSD victims, particularly in cases of multiple assaults.
- • Adaptive Response: Lower cortisol levels may reflect an adaptive process aimed at preventing damage to the frontal cortex and hippocampus from prolonged high cortisol exposure
- • Temporal Pattern: Cortisol levels decrease over time following abuse, suggesting ongoing neurobiological adjustment
- • Environmental Modulation: Children in institutional settings show attenuated stress reactivity compared to those in familial homes
Immune System Dysregulation
Alterations in inflammatory markers including interleukin-6 (IL-6) and other cytokines indicate systemic immune dysregulation following childhood sexual abuse. The stress response triggers chronic inflammatory responses that persist into adulthood.
Clinical Implications
Understanding HPA axis dysregulation is critical for developing targeted interventions. Trauma-informed care must address the underlying biological stress response system dysfunction, not merely psychological symptoms.
Digital Media Exposure & Neurodevelopmental Impact
Exposure to social media and sexualized material during childhood significantly affects neurodevelopment because the brain is still forming critical pathways for identity, attachment, impulse control, and emotional regulation. The developing brain exhibits high neuroplasticity and heightened sensitivity to repeated stimulation.
Reward System Dysregulation
Exposure to highly stimulating, adult-themed content prematurely activates reward systems, shaping expectations around relationships and distorting normal stages of emotional and sexual development. Frequent exposure to fast-paced digital media conditions the nervous system toward constant novelty and dopamine-driven engagement.
Attention & Impulse Control Deficits
Constant digital stimulation makes sustained attention, real-life connection, and delayed gratification more difficult. This contributes to attention difficulties, impulsivity, and reduced capacity for deep engagement.
Boundary & Consent Confusion
Sexualized content creates confusion around boundaries, consent, body image, and self-worth before children have cognitive maturity to process it safely. This contributes to distorted identity formation and vulnerability to exploitation.
Long-Term Consequences
Over time, early exposure may contribute to anxiety, compulsive behaviors, distorted identity formation, and vulnerability to exploitation. Protecting children's sensory and cognitive environments is essential for healthy neurodevelopment.
Documented Fatal Cases: Sextortion & Exploitation
Jordan DeMay (Michigan, 2022)
17-year-old died by suicide after being targeted in a financial sextortion scam. Attackers coerced explicit images and subsequently bombarded him with extortion demands, illustrating how online exploitation can rapidly escalate to fatal outcomes.
Gavin Guffey (South Carolina)
Teen died by suicide after being targeted in a sextortion scheme. His father, South Carolina lawmaker Brandon Guffey, has since become an advocate for sextortion awareness and prevention legislation.
West Virginia Teen (15 years old)
Died by suicide after sextortion attackers bombarded him with messages following coercion of illicit images. Case demonstrates the acute psychological distress and rapid escalation potential of sextortion schemes.
Kristen Galvan (15 years old)
Trafficked teen murdered after being groomed and exploited on social media. Case demonstrates how online exploitation can escalate to fatal violence through trafficking networks.
Kochi, India (6-year-old girl)
Autopsy revealed sexual abuse prior to death, underscoring how ongoing abuse can culminate in fatal outcomes. Case highlights the severe physical consequences of childhood sexual abuse.
Kerala, India (16-year-old girl)
Died by suicide after enduring repeated sexual assault. Case emphasizes the long-term psychological harm and suicidal risk associated with ongoing exploitation.
Global Trends & Epidemiology
Generative AI (GAI) Related CSAM
440,419
Reports in 2024-2025 (up from 6,835)
6,343% increase in one year
Total Missing Children Cases (2024)
29,568
91% recovery rate
Global Prevalence
1 in 4 girls experience CSA before age 18
1 in 13 boys experience CSA before age 18
South Asia Specific
12.5% of children reported rape or sexual assault before age 18
FBI and NCMEC report a "staggering" increase in financial sextortion targeting minors. Sextortion represents a form of image-based sexual abuse in which attackers coerce explicit images and subsequently extort victims through threats of exposure.
- • 3.5% of minors report sextortion victimization
- • 11% of minors report experiencing image-based sexual abuse
- • Sextortion intersects with CSAM production and distribution
NCMEC reports indicate that online child exploitation is escalating with "new and more extreme measures used to control victims." Children in every community are regularly being sexually exploited online.
Key Concern:
The convergence of AI-generated CSAM, sextortion, trafficking networks, and social media platforms creates unprecedented risk for minors.

Who Benefits
This program is grounded in neuroscience research on brain development, trauma recovery, and nervous system regulation. It complements the neurobiology research presented throughout this resource.
Our Approach
Begin Again International combines evidence-based neurodevelopment principles with practical, accessible tools. Rather than simply addressing symptoms, our programs focus on rebuilding the brain's sensory and processing foundations through neurodevelopment-informed strategies, creative expression, and faith-informed education. Each program provides tools that are easy to use, deeply empowering, and create measurable change in daily life.
Our customers include trauma survivors, returning citizens, veterans, caregivers, professionals, parents, and organizations seeking to understand how the brain and nervous system shape behavior and resilience.
Auditory Processing Evaluation
This comprehensive auditory processing test assesses your ability to process and recall number sequences. Trauma can affect auditory processing and memory. This evaluation helps you understand your current auditory capacity by requiring you to successfully process a number sequence 3 times without mistakes.
How It Works
- 1.Listen to a sequence of spoken numbers (0-9)
- 2.Click buttons to repeat the sequence you heard
- 3.Start with 3-digit sequences, progressing to longer ones
- 4.You have 3 attempts per level to get it correct
- 5.Test ends when you have used all 3 attempts
Note
Make sure your audio is turned on. Each number will be spoken with pauses between them.
