Childhood neglect and parental care perception in cocaine addicts: relation with psychiatric symptoms and biological correlates.
Childhood neglect and poor child-parent relationships have been reported to increase substance use disorders susceptibility. Stressful environmental factors, including emotional neglect, could affect individual personality traits and mental health, possibly inducing stable changes in hypothalamic-pituitary-adrenal (HPA) axis and brain mono-amine function, in turn involved in addictive behavior vulnerability. Therefore, we decided to investigate homovanillic (HVA) and prolactin (PRL) plasma levels, as expression of possible changes in dopamine function, ACTH and cortisol plasma levels, as measures of HPA axis function, and concomitant psychiatric symptoms profile in abstinent cocaine addicts, in relationship to their childhood history of neglect and poor parental care perception. ⋯ These findings suggest the possibility that childhood experience of neglect and poor parent-child attachment may partially contribute to a complex neurobiological derangement including HPA axis and dopamine system dysfunctions, playing a crucial role in addictive and affective disorders susceptibility.
