Filter by:The purpose of this study is to determine anxiolytic effect of multiple doses of CVL-865 using an experimental medicine model of carbon dioxide (CO2) inhalation in healthy volunteers.
The present study aims to investigate a potential mechanism of successful CBT for panic disorder, i.e., the reduction of excessive anxious apprehension and fear responses to panic-related body symptoms in the context of CBT treatment. In the present non-randomized interventional study, effects of cognitive behavior therapy on reported symptoms and fear responses to panic-related body symptoms are investigated. It is expected that symptom improvement during CBT is associated with a decrease in the activation of the brain's fear network to panic-related body symptoms.
The aim of the present study is to a) determine the comparative efficacy of the brief capnometry-assisted respiratory therapy (CART) and standard cognitive behavioural therapy (CBT), and b) to determine moderators and mediators. With the data collected from the study, the investigators will test the following hypotheses: (a) CART will be as effective in treating PD/A as CBT, albeit in shorter time, b) patients with greater respiratory dysregulations, especially hyperventilation, at pretreatment will benefit more from CART, whereas patients with greater cognitive dysregulation will benefit more from CBT. CART, but not CBT, will result in reversal of hyperventilation.
To investigate the efficacy and mechanisms of change of an Internet-delivered transdiagnostic REBT intervention for adolescents with internalizing problems.
The aim of the present study is to investigate the effect of prefrontal transcranial Direct Current Stimulation (tDCS) on clinical severity, attentional bias and interoceptive accuracy in panic disorder (PD). The participants will be assigned to active and sham groups (1:1) and will receive 10 sessions of tDCS. The study will also examine if the effects may last for a month.
This study aims to specifically examine the in vivo electrophysiology and effects of direct stimulation of the human amygdala during conditioned and evoked fear. Investigators will also examine amygdala electrophysiology and the effects of stimulation during tasks to examine the effects of reward on fear memory. This study will recruit subjects with a history of temporal lobe epilepsy (TLE) who have undergone neurosurgical implantation with FDA-approved, NeuroPace RNS devices for treatment of seizures. These patients provide a unique cohort with (Responsive Neurostimulation) RNS devices capable of both recording and stimulating the amygdala during performance of fear-based, behavioral tasks.
Anxiety disorders affect over a quarter of the population, yet very little is known about the variables that predict treatment outcome. The planned study explores whether a patient's response to a physiological test involving inhalation of carbon dioxide predicts their response to exposure therapy.
After an initial phone screen process, approximately 50 participants will be enrolled and evaluated/screened in person after consenting to achieve 30 eligible participants with a principal diagnosis of GAD, panic disorder, or social anxiety disorder and high anxiety sensitivity (Anxiety Sensitivity Index score =20). Participants will be given a choice of either high intensity interval training (HIIT) or walking interventions, which will be completed over the course of 8 weeks. The goal of the study is to 1) obtain pilot data comparing the efficacy of HIIT vs. walking for effects on psychiatric, functioning and immune outcomes, 2) to identify adherence levels given the choice of exercise intensity, and 3) to identify proportion of individuals opting for each intervention. Results from this pilot study will be used to inform future grant applications including a K award.
Other psychiatric disorders, including anxiety, often co-occur with adult ADHD; with 85% of ADHD patients having at least one other psychiatric condition. The presence of a co-occurring anxiety disorder has been associated with additive clinical effects, leading to more global impairment, poorer outcome, greater resistance to treatment and increased costs of illness. Stimulants are effective first-line treatments for adult ADHD patients, however the literature has mostly examined these treatments in pure ADHD populations (i.e. without other psychiatric disorders). Thus, there is little information to guide physicians in making treatment decisions for patients with ADHD and a co-occurring condition. This trial aims to evaluate the efficacy and safety of methylphenidate hydrochloride controlled release capsules (Foquest) in treating adults aged 18-65 years with DSM-5 ADHD with and without a co-occurring anxiety disorder.The study uses a 14-week, randomized, placebo-controlled, cross-over design.
The primary goal of the present study is to identify mechanisms of therapeutic change of two theoretically contrasting therapeutic procedures: The first phase consists of comparing the outcome of the capnometry-assisted breathing therapy (BRT) with cognitive restructuring (CT). During the second phase participants of both interventions will undergo in-vivo exposure.
