NCT ID: NCT03863925 Completed - Depression Clinical Trials

Comparison of Propofol Target-Controlled Infusion Anesthesia and Bolus Injection in Electroconvulsive Therapy

Start date: August 15, 2017
Phase: Phase 4
Study type: Interventional

Electroconvulsive therapy (ECT) serves as an effective adjuvant or alternative modality for major depressive disorder, schizophrenia, or bipolar affective disorder refractory to or contraindicated to psychopharmacological treatment. Anesthetics have been introduced into ECT sessions to alleviate ECT-inducing discomfort sensation, tachycardia, arrhythmia, hypertension, and anxiety. Propofol is highly lipid soluble and able to rapidly cross the blood-brain barrier (BBB), which leads to rapid onset of sedation and hypnosis. Meanwhile, propofol has hemodynamic depressant effect and attenuates hypertensive surge during ECT. Characteristics mentioned above make propofol one of widely used anesthetics for anesthetized ECT. Propofol can be administered with bolus injection or target-controlled infusion (TCI). Compared with bolus injection, TCI provides relatively constant concentration at site of interest based on computer simulation with input of pharmacokinetic parameters, such as age, body weight, body height, etc. However, propofol is also well known for anticonvulsant property, which may inevitably interfere with seizure propagation by electroconvulsive stimulus and diminish consequent efficacy. Thus, dosage of electrical stimulus may be increased to achieve ideal seizure quality in this setting, which also leads to higher risk of subsequent cognitive impairment. In our clinical practice, TCI system reduces total amount of propofol in comparison with bolus injection method. Therefore, we hypothesize that application of TCI system in anesthetized ECT relates to lower dosage of electrical stimulus and decreased incidence or severity of post-treatment cognitive impairment.

NCT ID: NCT03860597 Completed - Healthy Clinical Trials

Memantine Effects on Sensorimotor Gating and Neurocognition in Schizophrenia

Start date: April 1, 2018
Phase: Phase 4
Study type: Interventional

This application seeks to determine if neurophysiological metrics of memantine (MEM)-enhanced early auditory information processing (EAIP) in schizophrenia (SZ) mediate gains in auditory processing fidelity (APF) and auditory learning.

NCT ID: NCT03859973 Completed - Schizophrenia Clinical Trials

This Study Tests Whether BI 425809 Together With Brain Training Using a Computer Improves Mental Functioning in Patients With Schizophrenia

Start date: April 15, 2019
Phase: Phase 2
Study type: Interventional

This is a study in adults with schizophrenia. The study tests whether a medicine called BI 425809 together with brain training improves mental abilities. Participants take study medication once a day for 12 weeks. At the start of the study, the participants are put into 2 groups. It is decided by chance who gets into which group. One group gets BI 425809 tablets every day. The other group gets placebo tablets every day. Placebo tablets look like the BI 425809 tablets, but contain no medicine. During the study, all participants do brain training using a computer. The doctors regularly test mental abilities of the participants. The results of the mental ability tests are compared between the groups. The doctors also check the general health of the patients.

NCT ID: NCT03854409 Completed - Schizophrenia Clinical Trials

A Trial of Single- and Multiple-doses of Aripiprazole in Adult Subjects With Schizophrenia or Bipolar I Disorder

Start date: January 31, 2019
Phase: Phase 1
Study type: Interventional

The primary objective of this trial is to evaluate the pharmacokinetics (PK) of aripiprazole long-acting injectable (LAI) (420 mg) following deltoid or gluteal muscle administration in adult subjects with schizophrenia or bipolar I disorder.

NCT ID: NCT03848234 Completed - Schizophrenia Clinical Trials

Estradiol Patch as add-on to Antipsychotics in Patients With Schizophrenia, Schizoaffective or Schizophreniform Disorder

Start date: December 4, 2015
Phase: Phase 3
Study type: Interventional

To evaluate the effects of Estradiol patches vs placebo patches as add-on to antipsychotics on psychometric performance in patients with schizophrenia, schizoaffective or schizophreniform disorder

NCT ID: NCT03847753 Completed - Stroke Clinical Trials

Exploring the Comorbidity Between Mental Disorders and General Medical Conditions

COMO-GMC
Start date: January 1, 2000
Phase:
Study type: Observational [Patient Registry]

Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.

Effectiveness of Aripiprazole Long-acting Injection in Recent Onset and Chronic Schizophrenia Patients

Start date: June 1, 2018
Phase: Phase 4
Study type: Interventional

NCT ID: NCT03822416 Completed - Schizophrenia Clinical Trials

Treating Smokers With Mental Illness

Start date: March 1, 2019
Phase: Phase 2

This is a smoking cessation study that will enroll smokers who have been diagnosed with a severe mental illness. The study will use a combination of intensive tobacco treatment counseling and nicotine replacement therapy to assist smokers in cutting back on and quitting smoking over the course of six months.

NCT ID: NCT03820362 Completed - Schizophrenia Clinical Trials

The Role of Personal Identity in Psychotic Symptoms: a Study With the Repertory Grid Technique

Start date: February 2016
Phase:
Study type: Observational

Personal identity is being recently recognized as a core element for mental health disorders, with relevant clinical implications. However, scarcity of data exists on its role in schizophrenia and related disorders. The repertory grid (RGT), a technique derived from personal construct theory, has been used in different clinical and non-clinical contexts for the study of the construction perception of self and others, to appreciate aspects of interpersonal construing such as polarization and differentiation (unidimensional thinking) or self-construction.and Our study aims to explore the potential influence of the structure of personal identity and of other relevant cognitive factors (social cognition, metacognition, neurocognition) in positive and negative symptoms in people suffering schizophrenia and related disorders.

Impact of Inflammation on Reward Circuits, Motivational Deficits and Negative Symptoms in Schizophrenia

Start date: August 31, 2020
Phase: N/A
Study type: Interventional

This study will recruit persons with schizophrenia or schizoaffective disorder and will use an oral glucose tolerance test to test the hypothesis that insulin resistance drives inflammation.
