Filter by:The current study is a placebo-controlled, double-blind, randomized controlled study using a cross-over design, including Healthy Controls (HC) and participants with Panic Disorder (PD). The primary aim of the study is to investigate the neural correlates and behavioral effects of caffeine (versus placebo), and its impact on emotional reactivity, decision-making, and interoception, and compare the effects in individuals with PD vs HCs. Subjective anxiety and the occurrence of panic attacks will also be measured. Multimodal neuroimaging methods, such as structural and functional MRI, will be used to address the aims of the study. Emotional reactivity, emotional decision-making and interoception will be measured with experimental tasks in a 7 Tesla (7T) magnetic resonance (MR) scanner, jointly with measures of skin conductance, heart rate, respiratory rate, and self-reported ratings of anxiety and interoception. Emotional reactivity will be assessed using emotional and neutral faces. Emotional decision-making will be assessed with an approach-avoidance conflict task. Changes in interoception (bodily sensation, such as pulse and respiration) will be explored using a task in which participants are asked to focus on their breathing or an external stimulus. Caffeine effects on brain resting-state activity will also be assessed. All tasks will be conducted while in the 7T MR scanner. A secondary aim of the study is to examine the impact of genetic variability in the adenosine A2A receptor (ADORA2A) genotype (e.g., rs5751876 T/T) on the effects of caffeine (vs placebo), as ADORA2A genotype has previously been associated with elevated caffeine-induced anxiety.
This study aims at developing an online system for the remote delivery of EMDR therapy in Pakistan. Moreover, this study will compare the efficacy of online EMDR therapy with face-to-face EMDR therapy.
The aim of this study is to evaluate the efficacy of hydroxyzine compared to treatment as usual (TAU) for patients with panic disorder. By conducting a pilot study, we hope to provide initial data on the feasibility and potential impact of hydroxyzine for this population. This will inform the design and power calculations of a larger, more comprehensive study in the future. Objectives: To assess the feasibility of conducting a randomized controlled trial (RCT) of hydroxyzine for panic disorder. To evaluate the effectiveness of hydroxyzine compared to TAU in reducing panic symptoms in patients with panic disorder. To explore the potential side effects and tolerability of hydroxyzine in this population. Methods: This will be a single-center, open-label, randomized pilot study. A total of 30 patients with a primary diagnosis of panic disorder will be recruited from a psychiatric outpatient clinic. Participants will be randomly assigned to receive either hydroxyzine or TAU for 8 weeks. The primary outcome measure will be the change in panic symptoms as assessed by the Panic Disorder Severity Scale (PDSS). Secondary outcome measures will include the Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impression-Severity (CGI-S) scale. Participants will be assessed at baseline, 4 weeks, and 8 weeks. Adverse events will be monitored throughout the study. Expected Results: This pilot study is expected to provide preliminary data on the feasibility and potential efficacy of hydroxyzine for panic disorder. The results will inform the design of a larger RCT to further evaluate the efficacy of hydroxyzine for this population. Significance: There is a need for effective and well-tolerated treatments for panic disorder. If found to be effective, hydroxyzine could provide a new option for patients with this condition, potentially improving their quality of life and functioning. The results of this pilot study will inform the design of future studies and contribute to the development of evidence-based treatments for panic disorder.
Background. Self-management support is a complementary approach to treatment that aims to educate participants on the nature of anxiety and to improve their strategies to manage symptoms and well-being, thus presenting the potential to enhance recovery, improve outcomes, reduce recurrence rates and lower health care costs. There is limited evidence to support the effectiveness of group self-management support for anxiety disorders in community-based care. Objectives. This study aims at examining the effectiveness of a virtual group self-management support program (SMS) for anxiety disorders as an add-on to treatment-as-usual (TAU) in community-based care settings. We will also assess the incremental cost/effectiveness ratio and the implementability of the intervention. Methods. The trial is a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment (4-month post-randomization), and follow-ups at 8, 12 and 24-months. Intervention. The experimental condition will consist of a 10-week SMS program for anxiety disorders in addition to TAU. The control condition will receive TAU without restrictions for anxiety disorders. Inclusion criteria will comprise being 18 years old or older, French-speaking, and meeting Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for anxiety disorders: Panic Disorder, Agoraphobia, Social Anxiety Disorder, Generalized Anxiety Disorder. Patients will be recruited within four regions in Quebec (Canada). Outcome measures: The primary outcome measure is the Beck Anxiety Inventory (BAI). The secondary outcome measures include self-reported instruments for anxiety and depressive symptoms, recovery, self-management, quality of life, and service utilisation. Statistical analysis: Intention-to-treat analysis. A mixed effects regression model will be used to account for between and within-subject variations in the analysis of the longitudinal effects of the intervention. Expected outcomes. The rigorous evaluation of the SMS intervention in the real world will provide information to decision makers, health care managers, clinicians and patients regarding the added value of group SMS for patients with anxiety disorders. Widespread implementation of this intervention could lead to more efficient mental health care services, to better long-term outcomes and to a significant reduction in the extensive social and economic burden of anxiety disorders.
The purpose of this study is to evaluate the feasibility of an evidence-based system to recommend core interventions, before the beginning of treatment, to psychotherapists treating low-income patients with depressive or anxiety disorders.
This study is a double-blind, randomized, placebo-controlled, clinical trial in parallel groups in patients with panic disorder.
Adults with high anxiety sensitivity (AS) and a mental health diagnosis of anxiety, depression, or posttraumatic stress will be recruited and will be randomly assigned to either transdiagnostic cognitive behavioural therapy (CBT) for AS or disorder-specific CBT for their primary mental health problem. The study outcomes - AS, anxiety, mood, and substance use symptoms, and functional impairment - will be assessed at pre-and post-treatment and 6 and 12 months post-treatment via standardized self-report measures completed by participants and a standardized diagnostic interview.
Animal and human fear conditioning studies have repeatedly shown that administering propranolol before or after retrieval of a previously acquired fear results in an elimination of the fear expression. This approach, known as disruption of fear memory reconsolidation, is a promising new avenue for treating anxiety disorders. The present study aims to test its efficacy in patients with panic disorder.
Anxiety disorders are characterized by exaggerated levels of fear that are not proportional to the actual level of threat. More specifically, anxiety patients have marked deficits in the downregulation of fear reactions during situations of objective safety. Pre-clinical research on Pavlovian fear conditioning and extinction has discovered that fear downregulation stems from areas in the prefrontal cortex (the ventro-medial prefrontal cortex, vmPFC) that recruit intercalated cells in the amygdala to inhibit its central nucleus, which is responsible for a variety of behavioral expressions of fear (Milad & Quirk, 2012). Accordingly, functional magnetic resonance imaging studies (fMRI) revealed reduced vmPFC activity coupled with increased fear reactions during situations of objective safety in anxiety patients (Milad et al., 2009). Another core symptom of anxiety disorders, though much less investigated, is the excessive avoidance of situations that trigger the fears. These 'safety behaviors' often interfere with daily life activities and valued goals in life, and they are thought to perpetuate the exaggerated levels of fear by precluding opportunities to learn that the feared situations are actually not dangerous. Surprisingly, experimental research on avoidance behaviors in anxiety patients is virtually non-existent. This experiment modifies the Pavlovian fear conditioning procedure to include avoidance, and explores the behavioral and neural processes of this type of fear regulation in anxiety patients (trans-diagnostically) and healthy individuals.
Hypotheses The investigators hypothesize that among individuals who suffer from panic disorder there is higher incidence of co-morbid balance impairment than in the healthy population. The investigators hypothesize that the treatment of panic disorder, through the treatment of co-morbid balance impairment using virtual reality (VR) exposure therapy environment, is more effective than the exposure to still pictures from the same scene in VR without balance challenge or comparing to standard cognitive behavioral therapy (CBT) for the treatment of panic disorder. Rationale This research relies on previous studies, which have shown mutuality between anxiety and balance impairment, even if only sub-clinical. The VR-based training environment enables multi-sensorial stimulus in a dynamic interactively changing setting. With the addition of a cognitive task (dual task distracting the fear), the investigators can add cognitive load and therefore challenge the control of balance even more. Individuals who suffer from balance impairment avoid their exposure to many balance-challenging situations - a fact that may increase their anxiety. The investigators assume that a considerable number of PD individuals also experience balance control impairments - mostly subclinical ones. Moreover, balance impairment accompanies other psychiatric disorders, though not enough literature exists on the subject.
