Active clinical trials for "Psychotic Disorders"

Withania somnifera (WSE; Ashwagandha in Ayurveda) extracts have been used as an adaptogen or to build resistance to stress or diseases in indigenous medical systems in India for centuries. Modern scientific data for WSE indicate several bioactive molecules (withanolides, withanosides, indosides, withaferin-A, others) with significant immunomodulatory, anti-inflammatory and stress reducing properties. This study will examine whether a standardized extract of Withania Somnifera (WSE; Sensoril®) will improve total, positive, negative symptoms, and stress in patients with schizophrenia. The study will examine whether WSE reduces PANSS positive and negative symptoms and stress scores in subjects, and whether these improvements are mediated by changes in inflammatory immune indices. An additional aim will determine if patients receiving WSE will have fewer adjustments to their psychotropic medications that those assigned to placebo. The study will examine whether WSE will re-balance Th1/Th2 ratios (cytokine measures) and mediate a reduction of elevated hs-CRP levels. It is hypothesized that those subjects whose Th1/Th2 ratios normalize will likely have a greater magnitude of clinical improvement versus those subjects whose immune ratios remain unbalanced. The proposal is a 12-week, double-blind, placebo-controlled RCT of WSE added to antipsychotic medications in approximately 60 or more patients with schizophrenia with an exacerbation of symptoms. If efficacy is affirmed, this low cost extract could be studied further, and used quite readily across low, middle and high income countries.

Rater blinded trial of six weeks of Kuvan vs. multivitamin in 60 outpatients with schizophrenia or schizoaffective disorder. The aims are to evaluate an anticipated clinical response to Kuvan treatment including negative symptom and cognitive deficits, evaluate safety of Kuvan treatment for schizophrenic patients and evaluate the relationship of changes in plasma Kuvan levels and efficacy outcomes.

The purpose of this study is to investigate the short- and long-term effects of a 10-week walking program, based on the self-determination theory, in people with mental disorders. The investigators expect positive effects on: Physical fitness Physical activity Well-being (less feelings of anxiety, less feelings of depression) The investigators also expect underlying psychosocial processes to influence these effects.

The proposed pilot study is a randomized controlled study to assess effectiveness of transcranial direct current stimulation (tDCS) to enhance cognitive remediation therapy in patients with psychotic disorders. tDCS. Patients will be randomized into two arms: active tDCS vs. sham tDCS. The active tDCS will be applied at a current of 1-2 mA (milliamperes) via two saline soaked electrode sponges (3 cm x 4.5 cm) applied to the side of the head. The investigators hypothesis is that the use of tDCS will enhance the improvement seen with cognitive remediation therapy.

This study is to assess the bioavailability of LY03004 compared to Risperdal Consta as well as the evaluate the safety and tolerability and preliminary efficacy of LY03004 with repeat injections

The investigators propose to test whether curcumin nanoparticles will improve behavioral measures and biomarkers of cognition and neuroplasticity in patients with schizophrenia who are already receiving a stable dose of antipsychotic.

The purpose of this study is to evaluate the efficacy and safety of A-prexa compared to Zyprexa in patients with schizophrenia, schizophreniform disorder and schizoaffective disorder.

Investigating the effects of non-invasive transcranial current stimulation as a treatment for auditory hallucinations in patients with schizophrenia.

The purpose of the present study is to examine whether cognitive behavior therapy will reduce depressive symptoms and increase self-esteem for patients with a first episode psychosis.

Auditory verbal hallucinations (AVH) are a characterising symptom of schizophrenia. In the majority of patients, these AVH respond well to antipsychotic medication. Yet, a significant minority continues to experience frequent AVH despite optimal pharmacotherapy. The number of alternative treatment options for this medication resistant group is currently low and most of them focus on coping with the hallucinations. Transcranial magnetic stimulation (TMS), in contrast, is a non-invasive technique of influencing cortical excitability. This technique has the potential to actually decrease the frequency and severity of medication resistant hallucinations. Several previous studies have assessed efficacy of low frequency rTMS, with contradicting results. A previous large study by the investigators group could not demonstrate efficacy of low frequency rTMS. A new stimulation protocol using theta burst rTMS (TBS) could provide a more effective therapeutic option. Objective: The present study aims to examine the efficacy of TBS on the severity of AVH. Study design: The objectives are tested in a randomized double blind placebo-controlled trail. Study population: 60 patients with the diagnosis of schizophrenia, schizoaffective disorder, schizophreniform disorder or psychosis not otherwise specified with frequent auditory verbal hallucinations will be included. Intervention: The participant will receive either 10 TBS treatments or 10 placebo treatments consisting of 900 pulses each with a 30 minute interval on the left temporoparietal area, distributed over 5 treatment days. Stimulation will be at 80% of the motor threshold. Main study parameters/endpoints: the main study parameter is the change in the severity of the AVH. The secondary study parameter is the number and severity of adverse events.
