Street Shadows and Neural Scars for Brain Plasticity: Neurological and Behavioral Consequences of Trauma and Drug Abuse in Street-Connected Children Wired for Survival

Abstract: Background: Street-connected children in India face chronic adversity, often compounded by trauma and substance abuse. These factors are known to affect cognitive development and emotional regulation, yet there is limited empirical research examining their combined impact on brain-related functioning in this high-risk population. This study aimed to explore how trauma and drug use influence neurocognitive and behavioral outcomes among on- and off-street children in urban India. Materials and Method: The sample consisted of 106 street-connected children (64 males, 42 females), aged 8 to 16 years (M = 12.4, SD = 2.3), drawn from urban cities: Allahabad, Kanpur, and Banaras. Standardized instruments were used to assess trauma exposure (CTQ), substance use severity (DUSI-R), cognitive functioning (Trail Making Test A & B, Digit Span), behavioral problems (CBCL), and neurological soft signs. Group comparisons and multiple regression analyses were conducted. Results: On-street children reported significantly higher trauma (M = 68.9) and substance use severity (M = 11.2) than off-street peers (M = 55.4 and M = 7.4, respectively). Cognitive assessments revealed lower working memory scores (Digit Span M = 7.2, SD = 2.1) and slower executive functioning (TMT-B M = 93.6 seconds). Behavioral problems were elevated, with mean CBCL externalizing scores reaching M = 66.7 (SD = 14.3. Although the regression model did not yield statistically significant predictors (R² = 0.011, p = .771), descriptive trends suggested a link between trauma, drug use, and neurobehavioral impairments. Conclusion: Findings highlight the neurodevelopmental impact of trauma and drug abuse among street-connected youth, particularly those with greater exposure to environmental instability. Interventions must extend beyond basic services to include trauma-informed, brain-based rehabilitation approaches. Policy reform is needed to recognize these children as neurologically at-risk and deserving of specialized, long-term support.
