BACKGROUND: Insomnia is highly prevalent in adults with Attention-Deficit/Hyperactivity Disorder (ADHD), worsening core symptoms, mood, and cognition. Despite its impact, pharmacological options remain limited. Dual orexin receptor antagonists, such as daridorexant, are a promising yet untested approach in this population. METHODS: In a naturalistic one-month study, 24 adults with ADHD and comorbid insomnia disorder received daridorexant 50 mg nightly. Sleep outcomes were assessed with the Insomnia Severity Index (ISI), Sleep Condition Indicator (SCI), and actigraphy-based measures. Secondary measures included ADHD symptoms (Barkley Adult ADHD Rating Scale-IV, BAARS-IV), cognitive performance (Conners’ Continuous Performance Test-3, CPT-3), and mood and anxiety (Symptoms of Depression Questionnaire, SDQ). RESULTS: ISI and SCI scores improved significantly (both p < .001). Actigraphy confirmed longer total sleep time, higher sleep efficiency, and shorter sleep onset latency; after correction, ISI/SCI improvement and longer total sleep time remained significant. Clinically, 62.5% achieved meaningful improvement (≥7-point ISI reduction), 25% partial-to-minimal, and 12.5% no change or worsening; nearly two-thirds reached non-clinical insomnia levels. CPT-3 revealed enhanced sustained attention and response consistency, with further gains in selective attention and reduced impulsivity among responders. BAARS-IV showed overall improvement, with the sluggish cognitive tempo subscale reaching significance. Mood and anxiety improved, and the SDQ appetite/weight subscale decreased significantly even after correction, suggesting reduced perceived appetite or weight. Daridorexant was well tolerated; two participants reported daytime sleepiness or sedation, and one discontinued due to persistent sedation. CONCLUSIONS: In this preliminary sample, daridorexant was associated with improvements in sleep, attention, mood and anxiety in adults with ADHD and insomnia, supporting further controlled trials.

3. Romo L, Getin C, Therribout N, Icick R, Fouques D, Zerhouni O. Perceived stress and addiction severity in adults with ADHD: A multi-domain analysis. Psychiatry Res. 2026; 362: 117189.
BACKGROUND: Attention deficit/hyperactivity disorder (ADHD) is associated with an increased risk of addiction. However, few studies have compared multiple addiction domains within the same analytic framework using harmonized metrics. This study examined the predictors of addiction severity across alcohol, tobacco, cannabis, internet gaming, and gambling in adults with ADHD symptoms. METHODS: Adults reporting ADHD symptoms completed an online survey. Z-standardized severity scores were analyzed via linear mixed-effects models (N = 847 observations from 394 participants) alongside demographics, stress (PSS-10), and ADHD symptoms. An exploratory logistic regression (N = 82) predicted gambling problems. RESULTS: Mixed-effects models revealed no significant main effect of addiction type (all p > .650), indicating that relative severity was comparable across domains. Perceived stress was a significant positive predictor of severity. Current and retrospective ADHD symptoms were not significantly associated with addiction severity. Binary logistic regression identified internet gaming severity as a significant risk factor for the presence of gambling problems (OR = 1.09, p = .037). Alcohol use was not a significant predictor. CONCLUSIONS: Internet gaming severity was associated with the presence of gambling problems. However, general addiction severity appears to be driven more by perceived stress than by ADHD symptoms themselves. Furthermore, internet gaming may represent a risk factor for gambling problems, though this preliminary finding requires replication.
