Filter by:Observational, short-term prospective, multicenter study to assess psychometric properties of the Spanish version of SWN-K scale in patients with schizophrenia.
The objective of the proposed study is to test if a single IV dose of ketamine (0.5 mg/kg) decreases symptoms of PTSD.
There is growing evidence that neuropeptides act as neuronal messengers in the brain and have diverse functions that may include the regulation of mood and behavior. For example, neuropeptide Y (NPY) is thought to play a role in the adaptive stress response. The therapeutic application of neuropeptides for psychiatric disorders has been limited by difficult and unreliable penetration of the blood-brain barrier (BBB). However, recent data suggest that intranasal administration may provide a means of effectively delivering some of these neuropeptides to the brain. Thus far it is unclear if this is the case for NPY. The aims of this project are: 1. To evaluate, in 15 healthy male volunteers aged 25-45, the effect of intranasal NPY administration (0, 50 and 100 nmol) on its levels in cerebrospinal fluid (CSF), measured by means of lumbar puncture using an intraspinal catheter between L4 and L5, and in plasma, measured using an intravenous catheter in the forearm. One of the three treatments will be administered to each participant in a double-blind fashion. The 0 nmol condition will serve as the placebo control. 2. To test the effect of intranasal NPY administration on mood and anxiety.
Almost 80% of panic disorder patients report difficulty sleeping. Sleep disturbances in turn may exacerbate underlying anxiety/panic attacks. Moreover, individuals with insomnia (sleep disturbance) are at higher risk of developing a new anxiety disorder. Therefore it is expected that improving sleep quality with medications along with other medications to treat anxiety component of panic disorder might be helpful. However, there is lack of pharmacological studies examining the effects of improving sleep disturbances with medications in panic disorder patients, which is a critical problem for providing optimal care to these patients. The objective of this proposal is to determine the effects of ramelteon (FDA approved for insomnia) on sleep disturbances in Panic disorder patients who are on escitalopram for underlying anxiety.
The purpose of this study is to evaluate the efficacy and safety of vortioxetine, once daily (QD), in adults with Generalized Anxiety Disorders.
Prazosin is an alpha-1 adrenergic receptor antagonist that has been used successfully in the treatment of trauma nightmares and sleep disturbance in combat veterans with PTSD, and alcohol dependence. The objective of this study is to evaluate the efficacy of prazosin (16mg) versus placebo in reducing alcohol consumption and decreasing symptoms of PTSD in patients with comorbid AD and PTSD.
This is an open label, randomised, parallel-group study to compare the efficacy and safety of quetiapine and valproate used as monotherapy in the treatment of mania in patients hospitalised for an acute manic episode. After given of informed consent and undergoing screening procedures, the patients will be randomised into quetiapine or valproate group on Day 1. The efficacy of study treatment on symptoms of mania will be assessed at Day 28. Patients will not permitted to use any psychoactive or antipsychotic medications throughout the study period other than those expressly permitted by the protocol. At each centre, the same individual will administer a specific psychiatric assessment for a patient at all study visits in order to reduce variability in rating scale scoring. Before the initiation of the study, a consistency assessment will be done among the investigators who conduct the scale assessment in each centre.
This study will examine whether interpersonal psychotherapy is as effective in treating post-traumatic stress disorder as the established therapies of prolonged exposure and relaxation.
The purpose of this study is to assess the impact of three different treatment modalities on panic symptoms, quality of life and use of health services among individuals consulting an emergency department for non cardiac chest pain and having Panic Disorder.
The purpose of this study is to assess the effectiveness of a cognitive-behavioral intervention for children aged 7 to 12 years with anxiety disorders who are referred to ordinary community clinics. The treatment will be conducted as individual therapy or group therapy.
