Transcranial direct current stimulation (tDCS) is a non-invasive form of neurostimulation with potential for development as self-administered intervention. It has shown promise safe and effective treatment obsessive compulsive disorder (OCD) in small number studies. The two most favourable targets appear to be the left orbitofrontal cortex (L-OFC) supplementary motor area (SMA). We report first study test these head-to-head within randomised sham-controlled trial. Our aim was inform design future clinical research studies, by focussing on acceptability safety intervention, feasibility recruitment, adherence tolerability tDCS, size any treatment-effect. FEATSOCS randomised, double-blind, sham-controlled, cross-over, multicentre study. Twenty adults DSM-5-defined OCD were treatment, comprising three courses clinic-based tDCS (SMA, L-OFC, Sham), randomly allocated delivered counterbalanced order.

Obsessive-compulsive disorder (OCD) is a chronic neuropsychiatric that often begins early in childhood. Patients with OCD are known to seek help late after onset, and therefore have long duration of untreated illness (DUI), which found correlate negative clinical outcomes. No meta-analysis has previously investigated this issue. Our protocol was pre-registered PROSPERO (CRD42020165226). We followed PRISMA-guidelines searched for relevant articles four electronic databases. Meta-analyses means based on random-effects (Der-Simonian-and-Laird-method) were used derive the pooled estimates.

Obsessive-compulsive disorder is one of the most common neuropsychiatric disorders with a higher lifetime prevalence than schizophrenia, often showing inadequate response to pharmacological and psychotherapeutic treatments. This study aimed examine efficacy adjunctive deep transcranial magnetic stimulation (dTMS) in randomized, sham-controlled set-up, addressing standard Forty-nine obsessive-compulsive patients were randomly allocated receive either high-frequency dTMS (20 Hz) or sham received 10 sessions treatment using H7 coil target dorsal anterior cingulate cortex medial prefrontal over period 2 weeks. Change Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores was primary outcome measure. Secondary measures changes Hamilton Anxiety Rating Depression rates as measured by Y-BOCS. The active group demonstrated significant reduction Y-BOCS compared (-10.4 vs -2.6 points; P < 0.001), an effect size 1.39. Full 75% versus 5% (P 0.001). depressive symptoms also improved significantly (Hamilton Scale: -9.1 -2.4 points, 0.001; -5.9 -1.8 Our that targeting obsessive-compulsive, anxiety, symptoms, faster fewer previous trials, suggesting may serve effective early intervention for wider range patients.

Effects of transcranial direct current stimulation (tDCS) at different cortical targets on cognition in obsessive-compulsive disorder (OCD): an exploratory analysis

International Clinical Psychopharmacology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 4, 2025

Transcranial direct current stimulation (tDCS) holds promise as a treatment for obsessive-compulsive disorder (OCD). Patients with OCD show impairment in specific domains of cognitive flexibility and response inhibition. We previously reported that tDCS produced positive clinical effect on symptoms. Here, we report secondary analysis neurocognitive data. In this randomized, double-blind, sham-controlled, crossover, multicenter feasibility study, adults diagnosis according to the diagnostic statistical manual mental disorders, fifth edition (DSM-5) received three courses clinic-based tDCS, targeting left orbitofrontal cortex (L-OFC), bilateral supplementary motor area (SMA), sham, randomly allocated delivered counterbalanced order. Cognitive assessments were conducted before 2-h after first each arm. Nineteen recruited. both L-OFC SMA significantly improved inflexibility, while sham did not (paired-sample t test, baseline vs. stimulation). No significant was found impulsivity (stop-signal reaction time) any arms. small sample patients OCD, single administration rapid improvement inflexibility but impulsivity. A definitive controlled trial OFC SMA, including markers, is indicated.

Clinical Oral Investigations, Год журнала: 2025, Номер 29(4)

Опубликована: Апрель 5, 2025

Abstract Objective This study investigates the frequency and characteristics of obsessive-compulsive (OC) symptoms Obsessive-Compulsive Personality Disorder (OCPD) in patients with Burning Mouth Syndrome (BMS). Background (OCD) is a chronic condition involving intrusive thoughts (obsessions) repetitive behaviors (compulsions), while personality disorder characterized by specific traits such as perfectionism, rigidity need for control. Both conditions frequently overlap, but their prevalence BMS has never been explored. Materials methods A total 151 were assessed using Inventory-Revised (OCI-R), Compulsive Assessment Scale (CPAS), Visual Analog (VAS), Short-Form McGill Pain Questionnaire (SF-MPQ), Hamilton Anxiety Depression scales (HAM-A, HAM-D), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness (ESS). Patients grouped based on OCI CPAS scores. Results n = 123 (81.6%) our sample females, mean age 63.19 ± 12.2 years. Clinically significant OC (OCI- R > 21) observed 41.7% sample, 37% met OCPD criteria; both present 24.5% patients. Conclusions show high traits, which should be taken into account clinicians considered therapeutic approach, given that they could complicate symptom management. Clinical relevance : By identifying these through OCI-R CPAS, may improve treatment strategies, perspective multidisciplinary tailored personalized approach.
