Filter by:Hallucinations or delusions that occur for the first time in older people with no acute medical problems or mood symptoms may be related to impending dementia. This study aims to confirm this hypothesis using novel blood biomarkers and Positron Emission Tomography (PET) imaging tracers, as well as non-invasive testing.
The goal of this clinical trial is to explore the potential of metformin in managing olanzapine-induced metabolic disturbance and hyperprolactinemia in patients with schizophrenia. The main questions it aims to answer are: 1. The effect of metformin on olanzapine-induced metabolic disturbance 2. The effect of metformin on olanzapine-induced hyperprolactinemia Participants will receive metformin 1500 mg/day for 8 weeks and assessments every 2 weeks.
The primary objective of the study is to characterize the pharmacokinetics of 3 formulations of olanzapine. A secondary objective is to evaluate the safety and tolerability of 3 formulations of olanzapine. Another secondary objective is to characterize the pharmacokinetics of ZYPREXA. The planned duration of the study for each participant is 19 weeks.
Schizophrenia (SZ) is a broad clinical entity characterized by different subjective symptoms,behavioural signs, and disease course. Research has pointed to numerous biological indicators tentatively associated with neurocognitive dysfunction, brain structural and neurochemical alterations. Cognitive deficits occur as early as the prodromal phase of the illness and significantly determine its outcome. Pathophysiologically, SZ is regarded as a disconnectome disorder in which frontal and temporal brain regions are functionally disconnected, which contributes substantially to the development of cognitive dysfunction. Impaired connectivity is related to synaptic (microconnectivity) and myelin (macroconnectivity) plasticity. With design-based stereology, a decreased number of oligodendrocytes (OLs) in the CA4 hippocampal subregion as the basis for disturbed myelination and impaired cognition, but also a decrease in the prefrontal cortex were observed. Animal studies demonstrated that clemastine enhances remyelination by increasing the differentiation of oligodendrocyte precursor cells (OPCs) and showed that aerobic exercise increases the rate of remyelination and proliferation of OPCs; this clinically meaningful effect of aerobic exercise is stronger in combination with clemastine. Furthermore, aerobic exercise improves everyday functioning, measured by the Global Assessment of Functioning (GAF) scale, and cognitive dysfunction in SZ and increases hippocampal volume, especially the volume in the hippocampal CA4 subregion. This regional volume change correlates negatively with global and cell-specific polygenic risk scores (PRSs), indicating that OPCs are involved in the genetic risk mechanisms and disturbed plasticity underlying SZ. In patients with multiple sclerosis, 90 days' administration of clemastine fumarate 10.72 mg/day, corresponding to clemastine 8 mg/day, significantly decreased the P100 latency delay of visual evoked potentials (VEPs) as a sign of myelin repair. In a bicentric, randomized, double-blind, controlled phase IIb clinical trial with a 2-arm parallel group design in patients with SZ, the study will compare the effects of aerobic exercise training plus clemastine vs. aerobic exercise training plus placebo over a period of 3 months on 1) everyday functioning and 2) working memory as primary outcomes.
The primary objective of the study is to evaluate the comparative bioavailability of TV-44749 administered subcutaneous (sc) to oral olanzapine (ZYPREXA®) at steady state in participants with schizophrenia. A secondary objective of this trial is to evaluate the safety and tolerability of multiple doses of TV-44749 administered sc in participants with schizophrenia. Another secondary objective of this trial is to compare additional pharmacokinetic parameters of TV-44749 administered sc with oral olanzapine (ZYPREXA®) at steady state in participants with schizophrenia. The total duration of participation in the trial for each participant is planned to be approximately 21 weeks.
This study aims to measure the effectiveness of the Music Therapy nursing intervention in reducing anxiety in outpatients diagnosed with severe mental illness (SMI) (bipolar disorder and schizophrenia). The intervention was structured over five weeks (ten 1-hour sessions, twice weekly). Objective measures (blood pressure, heart rate, and respiratory rate) and subjective measures (anxiety response and the subjective perception of relaxation) were taken before and after every session.
The study will compare standard high-intensity training with brief high-intensity training in people with schizophrenia-spectrum or bipolar disorder. The overall aim is to determine which of the two is superior in a long-term perspective.
To study the association between DISC1 RNA expression levels and cardiac function in patients with schizophrenia.
This study will determine the efficacy of hippotherapy (horseback-riding) program, as an adjuvant to standard psychiatric treatment, on the outcomes of patients with schizophrenia. A randomized controlled trial is conducted in a Community Mental Health Center. All participants are randomized into two groups (experimental and control groups) using blocked randomization. All participants received the standard psychiatric treatment, while the experimental group is additionally provided with a 16-session hippotherapy program for 8 weeks. All participants will be evaluated using the Positive and Negative Syndrome Scale, State-Trait Anxiety Inventory, Quality of Life Scale, UCLA Loneliness Scale at both baseline and after the intervention.
The study is to evaluate the safety, tolerability, and PK characteristics following single administration of HS-10509 in healthy adults, and multiple administrations of HS-10509 in patients with schizophrenia. Participants will have HS-10509 tablets or placebo once in the single ascending dose (SAD) part or once daily for 28 days in the multiple ascending dose (MAD) part.
