Treatment Summary

Haloperidol is a medication used to reduce symptoms of psychotic disorders, such as schizophrenia. It blocks the dopamine receptors in the brain, particularly in the mesolimbic and mesocortical systems, which helps to reduce psychotic symptoms. Haloperidol is also used off-label to treat Huntington’s disease and intractable hiccups. It has been found to be effective in reducing hallucinations, aggression/hostility, disorganized speech, psychomotor agitation and other psychotic symptoms. However, it can cause movement disorders, sedation, weight gain, and prolactin changes. Haloperidol may

How Haloperidol Affects Patients

Haloperidol is an antipsychotic drug that is effective in managing the positive symptoms of schizophrenia, such as hallucinations, hearing voices, and agitated behavior. However, it can cause movement problems, tiredness, weight gain, and other side effects.Haloperidol is generally better at causing fewer side effects than the lower potency first-generation antipsychotics, but it is more likely to cause movement problems. Taking too much haloperidol can cause an irregular heartbeat and even sudden death. In some cases, a serious condition called Neuroleptic Malignant Syndrome (NMS) can also occur. Symptoms of NMS include

How Haloperidol works in the body

Haloperidol works by blocking dopamine receptors in the brain, which can help reduce the symptoms of psychosis. It mainly blocks D2 dopamine receptors, but also has some effect on other receptors. It's believed that this blocking stops the overproduction of dopamine, which is thought to cause schizophrenia. Haloperidol also blocks receptors in the brainstem, which makes it an effective antiemetic. However, it has a strong binding to the D2 receptor, which can lead to unpleasant and long-lasting side effects known as extrapyramidal symptoms. For this reason, newer antipsychotic medications have been developed which have a lower

Transauricular Vagus Nerve Stimulation for Delirium

18+
All Sexes
Stony Brook, NY

The goal of this clinical trial is to test whether a non-invasive device called transauricular vagus nerve stimulation (taVNS) is safe, practical, and potentially helpful for patients in the hospital who develop delirium. Delirium is a state of confusion that often happens to people in the hospital who are sick or hurt. It can cause agitation, trouble paying attention and difficulty understanding what is happening. Delirium may slow overall recovery. This study will focus on feasibility and safety. Researchers want to learn whether taVNS can be given safely to critically-ill patients, whether patients and staff can tolerate the treatments, and whether the device produces measurable changes in brain activity and brain oxygen levels. The main questions this study aims to answer are: * Is it possible to deliver taVNS safely and consistently to patients in the ICU who have delirium? * Do patients tolerate the device without significant side effects or complications? * Does taVNS cause short-term changes in brain signals and oxygen levels that may suggest effects on brain function? This is an early feasibility study and there is no randomization or placebo group. All patients enrolled will receive taVNS in addition to their usual hospital care for delirium. What participants will do: * Be identified by their hospital care team and have a confirmed diagnosis of delirium. * Provide consent (or have a legally authorized representative provide consent if the patient cannot.) * Undergo brief assessments of thinking and attention (for example, the CAM-ICU test.) * Receive taVNS treatment using a small clip electrode placed on the ear. * The device sends gentle electrical pulses to the nerve in the ear. * Each session lasts about 30 minutes, given twice per day (morning and evening, with at least 6 hours between sessions). * Treatment can continue for up to 7 days while the patient is in the ICU. * Be monitored during and after each session. The study team will check vital signs, examine the ear for irritation, and ask about any discomfort. * On the first day, researchers will also record brain signals (EEG) and brain oxygen levels before and during stimulation using FDA-approved hospital monitoring devices. Possible risks and discomforts: * Mild side effects are possible, such as tingling, a tickling or pricking feeling in the ear, or temporary skin redness where the clip is placed. * Serious side effects are not expected, but all patients will be closely monitored during and after each session to ensure safety. Possible benefits: • Patients may or may not experience personal benefit. The main benefit is helping researchers learn whether this treatment approach is safe and practical. In the future, taVNS could potentially become a new tool to help treat or prevent delirium in hospitalized patients. Study size and duration: * The study will enroll a limited number of ICU patients with delirium at Stony Brook University Hospital. * Patients may take part for up to 7 days while hospitalized. Who can join: * Right-handed, adult patients in the ICU who are diagnosed with delirium. * People with certain medical conditions (such as brain bleeds, new strokes, pacemakers or other contraindications) may not be able to participate, for safety reasons.

Stepped Care Treatment for Anxiety

7 - 17
All Sexes
Houston, TX

Childhood anxiety disorders (CAD) are common and impairing. Family based cognitive behavioral therapy (CBT) is efficacious in treating CAD. Yet, many children do not receive care due to barriers such as limited provider availably, high treatment costs, and constrained family resources (e.g., time). To combat these barriers, other treatment methods have been developed. The stepped care treatment models maximize resources by providing low-intensity, low-cost interventions as a first time treatment, while stepping up care for those needing more intensive treatment. Specifically, a stepped care model for CAD that begins with a parent-focus intervention has great promise to deliver efficacious and cost-effective treatment without having to engage the child. While stepped care approaches show promise in treating CAD with comparable efficacy to standard CBT, there remains a large research-to-practice gap. The stepped care model for CAD that begins with a parent-focused intervention has yet been explored, and very little is known about intervention mediators that explain mechanisms of change. This research is being done to improve the reach and quality of services using a stepped care model, offering an affordable and practical solution to the widespread gap in youth mental health care.

Multimodal Intervention for Bipolar Disorder

18 - 35
All Sexes
Hamilton, Canada

People with bipolar disorder (BD) are at high risk of relapse following hospital discharge, partly due to a lack of BD-specific expertise and resources within community services required for comprehensive treatment. Although clinical guidelines recommend combining medication and psychosocial support, and research shows that early intervention is associated with improved outcomes, no structured care programs currently exist for individuals in the early stages of BD, contributing to chronic illness progression and preventable hospitalizations. This open-label pilot trial will assess the feasibility, acceptability, and preliminary effectiveness of a structured care pathway to support the transition from hospital to community care. The intervention includes group-based psychoeducation, individual peer support, and personalized support for community healthcare providers to improve illness insight, treatment adherence, and symptom management.

Brain Stimulation for Cannabis Craving in Schizophrenia

18 - 65
All Sexes
Nashville, TN

The central hypothesis is this: Brain circuits most relevant to cannabis use in schizophrenia are distinct from pathways identified in healthy controls who use cannabis. This study seeks to provide evidence that targeted stimulation of the DMN leads to both altered network activity and a concomitant behavioral change in cue-induced craving and cognitive performance in individuals with schizophrenia and schizoaffective disorder, while targeted stimulation of the L DLPFC leads to these changes in healthy controls who use cannabis. This study will test a model that integrates brain network pathophysiology and cognition to 1) explain the prevalence of cannabis use in schizophrenia and 2) identify a target for engagement in schizophrenia. This study seeks to establish a neuroscientific framework to guide future treatment-oriented studies aimed at reducing craving and improving cognitive performance in individuals with schizophrenia and schizoaffective disorder. This is a study of the effect of 2 rTMS interventions on functional connectivity and craving in individuals with schizophrenia or schizoaffective disorder and healthy controls who use cannabis. Aim 1: Target Engagement: Determine if rTMS manipulates functional connectivity of each target (DMN, L DLPFC) (n=100). Aim 2: Clinical Efficacy: Determine if rTMS affects cue-induced craving and if craving change correlates with change in functional connectivity (n=100). As an exploratory analysis, the factors that explain individual variance in rTMS-induced connectivity change will also be explored.
