Abstract
The increasing comorbidity of alcohol use disorder (AUD) and post-traumatic stress disorder (PTSD) associated with traumatic brain injury (TBI) is a serious medical, economic, and social issue. However, the molecular toxicology and pathophysiological mechanisms of comorbid AUD and PTSD are not well understood and the identification of the comorbidity state markers is significantly challenging. This review summarizes the main characteristics of comorbidity between AUD and PTSD (AUD/PTSD) and highlights the significance of a comprehensive understanding of the molecular toxicology and pathophysiological mechanisms of AUD/PTSD, particularly following TBI, with a focus on the role of metabolomics, inflammation, neuroendocrine, signal transduction pathways, and genetic regulation. Instead of a separate disease state, a comprehensive examination of comorbid AUD and PTSD is emphasized by considering additive and synergistic interactions between the two diseases. Finally, we propose several hypotheses of molecular mechanisms for AUD/PTSD and discuss potential future research directions that may provide new insights and translational application opportunities.

Abstract
OBJECTIVE This study aimed to investigate ADHD in adult outpatients seeking treatment for a behavioral addiction and to identify the specificity of psychopathological features if the behavioral addiction cooccurs with adult ADHD. METHOD Sixty-five outpatients consulting for a behavioral addiction were assessed for ADHD (DIVA-5), addictive disorder (alcohol, tobacco, cannabis, gambling, gaming, food, and sex), impulsivity (UPPS-P), and emotion dysregulation (DERS-36). RESULTS In our sample of outpatients seeking treatment for a behavioral addiction, adult ADHD was independently associated with higher compulsive sexual behavior disorder severity, "sensation seeking," "positive urgency," difficulties in "goal-directed behavior," "impulse control," and use of "emotion regulation strategies" in the context of intense emotions. A 19% of the sample was diagnosed for adult ADHD. CONCLUSION The association of adult ADHD with specific dimensions of impulsivity and emotion dysregulation, pave the way for future clinical and research perspectives.
