VIA Family - Family Based Early Intervention Versus Treatment as Usual

Start date: September 25, 2017
Phase: N/A
Study type: Interventional

This RCT aims to investigate the effect of an early family-based intervention (VIA Family) focusing on reducing risk and increasing resilience for children in families where at least one parent has a severe mental illness.The study is a randomized clinical trial including 100 children age 6-12 with familial high risk.The children and their parents will be assessed at baseline and thereafter randomized and allocated to either Treatment as Usual or VIA Family.

Combining rTMS With Varenicline to Prevent Smoking Lapse in Schizophrenia

Start date: July 1, 2018
Phase: Phase 2
Study type: Interventional

Tobacco smokers with schizophrenia are known to be resistant smokers, with high rates of smoking and inability to quit in the long-term, often related to smoking relapse. This may relate to problems with frontal lobe function associated with schizophrenia, which make these patients have great difficulty in dealing with smoking withdrawal, urges and cravings. The current study will develop a combination approach that takes advantage of brain stimulation of the frontal lobes (repetitive transcranial magnetic stimulation (rTMS), in combination with the anti-smoking drug varenicline, to prevent smoking lapse using a well-established human laboratory method. Results from this study may have important implications for developing novel treatment approaches for smokers with schizophrenia.

NCT ID: NCT03497013 Recruiting - Tardive Dyskinesia Clinical Trials

Effect of tDCS on Cognition, Symptoms in Chronic Schizophrenia Patients With Tardive Dyskinesia

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

The aim of the study was to evaluate the efficacy, safety, and cognitive function of transcranial direct current stimulation (tDCS) in chronic schizophrenia patients with tardive dyskinesia (TD).

Smoking Cessation With Varenicline in Schizophrenia: Antipsychotic-Induced Neurological Symptoms as Correlates

Start date: July 2018
Phase: Phase 4
Study type: Interventional

To test the feasibility of studying effects of smoking cessation with varenicline on antipsychotic drug-induced neurological side effects, we propose a 12 week pilot study of smoking cessation treatment with varenicline in 10 schizophrenia or schizoaffective disorder patients who are actively smoking and have pre-existing TD while receiving stable doses of antipsychotics. Subjects will be followed after a 2 week baseline period to assess changes in smoking status and neurological symptoms using standardized rating scales. The aim is to examine clinically significant effects on antipsychotic-induced neurological side effects that may warrant further investigation.

Substance Misuse To Psychosis for Stimulants

Start date: June 1, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

In Hong Kong, less than 5% of stimulants abusers were reported to misuse these substances via injection. Also, it is well known that patients with co-morbid substance abuse/dependence and psychosis or schizophrenia-related disorders are prone to earlier treatment discontinuation and high oral medication non-adherence, resulting in poorer overall outcomes. With the recent availabilities of the 4-weekly long-acting injectable form of aripiprazole, and the 4-weekly and the 3-monthly long-acting injectable form of paliperidone palmitate, on the background of the surging phenomenon of stimulant misuses in Hong Kong, it is a timely opportunity to conduct an early pharmacotherapy intervention study to offer an evidence-based strategy aiming to stop individuals with substance use disorders with psychosis to develop into a more chronic disabling dependence or co-morbid state.

NCT ID: NCT03485339 Not yet recruiting - Schizophrenia Clinical Trials

Substance Misuse To Psychosis for Ketamine (SToP-K)

Start date: May 2, 2018
Study type: Observational

Evidence suggests that repeated or chronic ketamine use, as compared to acute ketamine users, posed a higher clinical risk of developing psychotic disorders, potentially related to the underlying chronic N-methyl-D-aspartate receptor (NMDAR) dysfunction, and a higher risk of suffering from schizophrenia particularly in those genetically susceptible, or genetically predisposed ketamine abusers. With ketamine infusion rises as a emerging hope as an acute treatment for depression and suicidality under the shadow of unknown longer term psychotomimetic effects peculiarly amongst repeated or chronic use, the current case-control study aims to investigate: a) if repeated or chronic ketamine use is associated with an increased risk of psychosis by comparing those ketamine abusers with and without psychosis, and to those non-ketamine-using drug abusers with psychosis; and b) if genetic predisposition from single nucleotide polymorphisms are associated with risk of psychosis in ketamine abusers.

NCT ID: NCT03485131 Completed - Schizophrenia Clinical Trials

Transcranial Direct-current Stimulation (tDCS) in Treatment Refractory Auditory Hallucinations

Start date: April 2014
Phase: N/A
Study type: Interventional

This is a 4 week therapeutic pilot study with a 4 week follow-up period involving inpatients with treatment resistant DSM-IV schizophrenia or schizoaffective disorder diagnosis. Each eligible subject will receive either 20 minutes of active tDCS (transcranial direct-current stimulation) or sham stimulation twice a day on 5 consecutive weekdays for 4 weeks with a 4 week follow-up period.

NCT ID: NCT03483909 Recruiting - Clinical trials for Schizophrenia and Related Disorders

Transcranial Magnetic Stimulation to Improve Gesture Control

Start date: January 29, 2018
Phase: Phase 1/Phase 2
Study type: Interventional

The majority of schizophrenia patients is impaired in hand gesture performance, which contributes to poor functional outcome and poor communication skills. The left inferior frontal gyrus (IFG) and the left inferior parietal lobe (IPL) are key nodes of the gesture network, which is less active in patients with schizophrenia. Here, the investigators test single sessions of rTMS/TBS known to either enhance or inhibit local brain activity for app. 1 hour. The investigators aim to determine, which protocol may improve gesture performance in patients and healthy controls. This is a randomized, double-blind, cross-over, placebo-controlled single-center trial in 20 patients with schizophrenia spectrum disorders and 20 healthy controls. Gesture performance will be tested immediately after each TMS session, which are separated by 48 hours. Results of this study will inform larger interventional trials comparing 2 TMS protocols with repeated administration.

Thinking Skills at Work: Cognitive Remediation Therapy for Patients With Serious Mental Illness

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to help people with serious mental illness get and keep the job they want by improving their thinking skills, using cognitive remediation therapy. For people with serious mental illness, the Individual Placement and Support (IPS) Program is an effective approach to help people become employed. Despite its general success, still only 55% of clients find employment. Most of that success occurs in the first three months; after six months, the chances of finding competitive work are quite low. Among those who fail to find employment with IPS, cognitive dysfunction is often a significant problem. The proposed study will target IPS clients who have not found work after 3 months of employment-support services: our hypothesis is that, after three months with no success, the addition of cognitive remediation to IPS will improve employment rates (compared to those who continue to receive IPS alone). The proposed randomized controlled trial will use a single-blind study design, focused on IPS clients who are slow to (or may never) find employment success. Specifically, the proposed study will have two treatment arms: a) cognitive remediation added to continued IPS services, and b) continued IPS services alone. The study will collaborate with IPS workers at 11 Mental Health and Substance Use (MHSU) clinics to identify clients who are non-responders in the first 3 months, and seek their consent to participate in the study. They will be randomized to either TAU (continuation with IPS and other standard treatments), or TAU plus cognitive remediation. The CRT will consist of computerized cognitive exercise practice, strategy coaching, and teaching coping/compensatory strategies for 12 weeks. Clients will be assessed at 3-time points: prior to the start of cognitive remediation ("baseline"), end-point (3-month), and 6 months after the endpoint evaluation. Primary outcome measures will include success at gaining a competitive job, total hours of competitive employment, and neuropsychological measures of cognition.
