The Role of Dysmyelination in Cognitive Impairment of Psychotic Spectrum Disorders

This is a single center study that uses both between-group comparisons and correlational analyses to establish biomarkers of dysmyelination and cognitive impairment in Psychotic Spectrum Disorders using imaging and neuropsychological assays.The study will provide non-invasive biomarkers of cognitive dysfunction in Psychotic Spectrum Disorder.

Phase N/A

Trajectories of Treatment Response as Window Into the Heterogeneity of Psychosis: a Longitudinal Multimodal Imaging Study

Schizophrenia is a heterogeneous disorder that likely involves multiple underlying pathological mechanisms, which has plagued attempts to identify rational therapeutic targets. All available antipsychotic drugs (APD) are dopamine receptor antagonists, but clinical response is variable, with a third of patients being partial responders, and a third non-responders. Arguably, those who ...

Phase N/A

Neural Oscillations as Genetic and Functional Biomarkers in Normal and Disease States

There are several studies and hypotheses to be tested. This project includes a cross-sectional study design measuring brain waves, clinical symptoms, cognitive and functional ability, and genetic information in schizophrenic patients and normal controls. Subjects are expected to do a brain wave recording (EEG/ERP), role-play test designed to measure functionality ...

Phase N/A

Dallas 2K: A Natural History Study of Depression

This is a non-randomized, natural history, non-treatment, longitudinal cohort study. Participants will be receiving standard of care treatment for depression and other comorbidities from their treating clinician and will be allowed to continue such treatments in this study. There are no experimental study procedures, other than methods used for data ...

Phase N/A

Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care

The purpose of this study is to characterize the PK ( Pharmacokinetics) of understudied drugs administered to children per standard of care as prescribed by their treating caregiver. This will be accomplished by the collection of biological samples during the time of drug administration per standard of care as prescribed ...

Phase N/A

Role Functioning Changes NOS

The early symptoms of major mental disorders, such as bipolar disorder and schizophrenia, can be non-specific, attenuated, or intermittent. These symptoms nevertheless frequently interfere with an individuals' ability to effectively carry-out multiple aspects of their everyday lives, including social, vocational, and educational functioning. Functional changes may in fact occur before ...

Phase N/A

Striatal Connectivity and Clinical Outcome in Psychosis

In this proposed study, the study will examine treatment-related effects on functional brain circuitry in first episode schizophrenia. Converging lines of evidence suggest a key role for striatal disconnectivity in the pathophysiology of psychosis. The proposed study will utilize resting state functional magnetic resonance imaging (rs-fMRI), as well as fMRI ...

Phase N/A

The Gut Microbiota of Bipolar and Depression

Background: MDD (Major Depressive disorder) and BD (Bipolar disorder), whose specific pathogenesis is still unclear, are both a multi-factorial disease being caused by biological, psychological and social factors. Accumulating evidence suggests that gut microbiota play an important role in brain functions and in the pathogenesis of neuropsychiatric diseases, such as ...

Phase N/A

Rostral Dorsal Cingulum Bundle Connectivity in Patients With Bipolar Disorder Type I

The overall goal of this study is to employ diffusion-weighted imaging (DWI) and tractography to investigate differences in connectivity in the rostral dorsal cingulum bundle (CB) in patients with bipolar disorder type I (BDI) compared to matched controls, and to utilize this information to determine if high-frequency deep brain stimulation ...

Phase N/A

Comparison of Aripiprazole Versus Risperidone on Brain Morphology Using MRI

The purpose of this study is to use a direct measure of brain volume and matter (by means of MRI) to determine if there is a differential effect between aripiprazole and risperidone on brain morphology in participants with first-episode psychosis. A secondary objective is to see if fasting metabolic indices ...
