Neurological Sciences, Год журнала: 2025, Номер unknown

Опубликована: Апрель 8, 2025

Abstract In the present study, we investigated differences in cerebrospinal fluid (CSF) orexin-A levels among patients with different neurocognitive disorders, such as mild or moderate to severe Alzheimer’s disease (AD; mAD, msAD, respectively), behavioral variants of frontotemporal dementia (bv-FTD), non-fluent primary aphasia (NFPA), and idiopathic normal pressure hydrocephalus (iNPH). A total 214 participants were evaluated (mAD, 45; 31; bv-FTD, 12; NFPA, 22; iNPH, 13; non-demented elderly controls, 91). The highest CSF found iNPH (263.31 ± 56.89 pg/mL). Patients affected by NFPA (210.86 61.99 pg/mL), msAD (173.04 19.76 pg/mL) showed higher concentrations than controls (145.18 27.01pg/mL) ( p < 0.001).

Summary Insomnia disorder may affect mental health, increasing suicidal risk. Targeting insomnia is crucial in the clinical practice. Sixty‐six consecutive patients with according DSM‐5‐TR criteria were treated dual orexin receptor antagonist, daridorexant 50 mg. Baseline (T0), 1 month (T1) and 3 (T2) evaluations performed. severity (Insomnia Severity Index), mood, anxiety symptoms risk (Beck Depression Inventory‐II, Young Mania Rating Scale, Self‐Reported Anxiety Suicidal Ideation Scale), dysfunctional insomnia‐cognitive factors pre‐sleep arousal (Dysfunctional Beliefs About Sleep, Pre‐Sleep Arousal Scale) evaluated. The final sample included 66 ( n = 36, 54% females, mean age 60 ± 13.6 years). Most of them, 64%, suffered from comorbid unipolar/bipolar depression, disorders substance use disorders. Repeated ANOVA analyses showed that Index, Dysfunctional Sleep Scale total score decreased across time F 68.818, p < 0.001; 47.561, 28.142, 0.001, respectively).

The potential use of daridorexant in eating disorders: beyond the treatment of insomnia?

International Clinical Psychopharmacology, Год журнала: 2024, Номер unknown

Опубликована: Май 9, 2024

A strong interplay exists between sleep and dietary habits, disturbances have been repeatedly documented in individuals with eating disorders (EDs). The orexin system - implicated regulation, energy homeostasis, food reward may represent a mechanist link alterations disordered behaviors. Daridorexant is dual receptor antagonist (DORA) recently approved for the treatment of insomnia, demonstrated efficacy tolerability. Owing to its action on neurons, compound represents an intriguing option addressing both sleep-related core symptoms EDs. By inhibiting motor hyperactivity, daridorexant reduce excessive physical exercise anorexia nervosa (AN) restricting type. Additionally, exert anti-binge effects, suggesting broad applicability binge ED, bulimia nervosa, binge/purging AN. In this framework, emerges as promising therapeutic option, offering multifaceted approach improving circadian rhythms, balance, overall quality life diverse ED subtypes.

Early life stress and hormonal status influence orexin‐1 receptor expression in structures regulating cardiorespiratory responses to CO₂

Abstract Excessive cardiorespiratory responses to CO 2 are a hallmark of panic disorder (PD). Female sex and exposure early life stress risk factors for PD. Neonatal maternal separation (NMS; 3 h/day, postnatal days 3–12) augments the ventilatory response by ∼35% relative controls; this effect is most notable during pro‐oestrus but not observed in males. Orexin‐1 receptor (OX1‐R) antagonism attenuates NMS females. In limbic system, ovarian hormones influence OX1‐R expression, impact these on OX1‐Rs regions regulating unknown. Here, we hypothesised that determine expression structures response; used situ hybridisation quantify OX‐1R mRNA brains adult control rats. Brains were harvested from females either (high hormones) or weeks post ovariectomy (OVX; low hormones); males included comparison. Hormonal status influenced intensity signal medial amygdala, raphe obscurus (RObs) A5 area, direction changes (increase vs. decrease) was structure‐specific.

A Preliminary Report on the Effects of Daridorexant in Patients with Comorbid Insomnia and Substance Use Disorders

Pharmaceuticals, Год журнала: 2025, Номер 18(3), С. 378 - 378

Опубликована: Март 6, 2025

Background. Sleep disturbances are frequent in patients with substance use disorders (SUDs) and associated craving addiction relapses, leading to increased clinical severity detrimental outcomes. Daridorexant, a selective dual orexin receptor antagonist, has been approved for persistent insomnia disorder (ID), but specific insights on SUDs lacking. Methods. This observational, retrospective study investigated the effects of three-month treatment daridorexant (50 mg/day) 41 outpatients comorbid IDs SUDs. Improvement subjective sleep measures, assessed Insomnia Severity Index (ISI) total time, was primary outcome measure. Changes anxiety depression symptoms, quality life, global severity, were also through following: Hamilton Anxiety Depression Rating Scale; Five-item World Health Organization Well-Being Index; Clinical Global Impression Visual Analog Scale Craving. Results. All outcomes significantly improved throughout treatment, which generally safe well tolerated, mild transient drowsiness sluggishness reported 21.1% patients. Similar improvements observed psychopathology, craving, positive correlations found among ISI scores anxiety/depression symptoms craving. An abstinence rate (i.e., absence any use, regardless amount, treatment) 65.8% detected at endpoint. Conclusions. These preliminary findings suggest that might represent promising tool treating Identifying interventions effectively targeting good safety/tolerability profile is crucial achieve remission full functional recovery.

Nanoparticles targeting the central circadian clock: Potential applications for neurological disorders

Advanced Drug Delivery Reviews, Год журнала: 2025, Номер unknown, С. 115561 - 115561

Опубликована: Март 1, 2025

Circadian rhythms and their involvement with various human diseases, including neurological disorders, have become an intense area of research for the development new pharmacological treatments. The location circadian clock machinery in central nervous system makes it challenging to reach molecular targets at therapeutic concentrations. In addition, a timely administration agents is necessary efficiently modulate clock. Thus, use nanoparticles dysfunctions may accelerate clinical translation by addressing these two key challenges: enhancing brain penetration and/or enabling formulation chronodelivery systems. This review describes implications pathologies, reviews potential modulators suggests how nanoparticle-based formulations could improve success. Finally, integration into chronopharmaceutical drug delivery systems will be described.
