How Clozaril Affects Patients

Clozapine is a medication used to treat schizophrenia, and works by targeting serotonin, dopamine, adrenaline, and histamine receptors in the brain. It can cause side effects such as drowsiness, low blood pressure, and dry mouth. It also carries a risk of serious reactions, such as agranulocytosis (low white blood cell count) or myocarditis (inflammation of the heart muscle). Your doctor will monitor your white blood cell count and other lab values closely while taking this medication, and will also check for signs of myocarditis. If you experience any of these reactions, you should stop taking cl

How Clozaril works in the body

Clozapine works to treat psychosis by blocking certain receptors in the brain. It blocks dopamine receptors to reduce positive symptoms, and serotonin receptors to reduce negative symptoms.

Clozaril for Bipolar Disorder in Remission

Clozaril has been a life-saver for me. I've tried many other drugs with varying degrees of success, but the side effects were always too severe. With Clozaril, I finally found a medication that is effective without being overly debilitating.

Clozaril for Treatment-Resistant Schizophrenia

Weight gain was a bit extreme, but this drug really helped with my insomnia. I have to go for monthly bloodwork and appointments with the doctor, but it's worth it. The pain in my joints and muscles wasn't severe.

Clozaril for Schizophrenia

My brother has been on Clozaril for 12 years plus. He has been in and out of hospitals his whole life and this drug has enabled him to lead somewhat of a normal life. Now, we are unable to find a doctor who takes Medicare and will prescribe this medication. It has been devastating for our family.

Clozaril for Suicidal Behavior in Schizoaffective Disorder

So far, clozaril has been working great for me. I've only been taking it for a week, but I feel like I'm able to cope better already. I've tried other drugs in the past, but this one seems to be the best fit for me.

Clozaril for Treatment-Resistant Schizophrenia

I've been using this medication for a while now and it's starting to impact my memory. It's becoming difficult to keep a job or maintain relationships when I can't remember things. That said, it's still been helpful overall.

Clozaril for Schizophrenia

I've been on clozapine since 1995 and it's been effective for me. The weight gain is an issue, but I'm able to keep a full-time job because of the medication. I have been told that there may be a slight heart issue that is not caused by clozapine, but I would try everything else before starting this medication again.

Patient Review

Clozaril for Schizophrenia

After my diagnosis last year, I was hospitalized for four months. I was put on Cloazaril after trying three other atypical antipsychotics, and it has been a total game-changer. Within three months, I was back to work and happy again. The downside is that it can make you sleepy, and you have to get your blood drawn and weigh yourself every week.

Sleepio for Suicidal Thoughts

14 - 18
All Sexes
Piscataway, NJ

The purpose of this research study is to compare (vs. treatment as usual) a brief (6-session), empirically supported, and highly disseminable version of digital (i.e., smartphone or web-based) cognitive behavioral therapy for insomnia (dCBT-I), called SleepioTM, in suicidal adolescents with co-occurring insomnia during the high-risk post-hospitalization period. Suicide is the 2nd leading cause of death among adolescents. Sleep problems, such as insomnia symptoms-the most common sleep problem in youth-may be a particularly promising treatment target to reduce suicide risk in adolescents. The investigators propose to test the feasibility, acceptability, and effectiveness of dCBT-I in a two-site (Rutgers and Old Dominion University) pilot study trial. Adolescents, 14-18 years-old, recently hospitalized for suicide risk with co-occurring insomnia (n=80, 50% at each site), will receive either dCBT-I (six weekly, 20-minute sessions) plus post-hospitalization treatment-as-usual (TAU) or TAU alone. Adolescents will complete assessments pre-treatment, during the treatment phase including at the end of treatment, and 1-month follow-up post-treatment.

fMRI for Cognitive Flexibility

18 - 35
All Sexes
Iowa City, IA

The goal of this basic experimental research study is to examine how the human thalamus supports flexible thinking and behavior. Specifically, the research aims to elucidate how the mediodorsal (MD) thalamus encodes and updates "context"-the mental framework that determines which rules or actions are relevant in a given situation. This work may contribute to understanding why certain psychiatric conditions, such as schizophrenia and ADHD, involve difficulties with cognitive flexibility and control. The primary research questions are: Does the MD thalamus represent the context that organizes how working memory guides task selection? Does the MD thalamus signal when context needs to be updated after a change in task demands? Do these thalamic representations support generalization to new situations or rules? Participants will complete cognitive tasks while undergoing high-resolution brain imaging using 7-Tesla MRI. The investigators will combine behavioral data, computational modeling, and advanced neuroimaging analyses to examine how the thalamus interacts with the cortex during flexible decision-making.

Repetitive Transcranial Magnetic Stimulation for Schizophrenia

18 - 65
All Sexes
Nashville, TN

The central hypothesis is this: DMN connectivity can be modulated with inhibitory cTBS when delivered on an accelerated treatment schedule. This study seeks to provide evidence that accelerated, network-targeted inhibitory stimulation of the DMN leads to both altered network activity and a concomitant behavioral change in cognitive performance in individuals with schizophrenia and schizoaffective disorder. This study will also compare the effect of inhibitory cTBS in healthy individuals, as it may also lead to both altered network activity and a behavioral change in cognitive performance in individuals without schizophrenia or schizoaffective disorder. If successful, this study will have identified a safe, effective, and broadly applicable treatment for cognitive impairment in schizophrenia that has potential for translation into many other psychiatric and neurodevelopmental disorders, such as autism.

Schizophrenia is a common and severe psychiatric illness characterized by extreme disturbances of cognition and thought, affecting language, perception and sense of self. This study will assess adverse events, change in disease activity, and how oral emraclidine moves through the body in adult participants with schizophrenia Emraclidine is an investigational drug being developed for the treatment of schizophrenia. Participants are placed in one of two parts, Part A or Part B, where each group will receive a different treatment. Participants will receive either oral emraclidine or placebo. Approximately 258 participants will be enrolled across roughly 32 sites in the United States. Participants in Part A will be assigned to one of multiple ascending doses of emraclidine or placebo administered orally for 14 days or up to 21 days. Participants in Part B will receive Emraclidine or placebo administered orally for up to 42 days. Participants will be followed for 30 days after the last dose of the study drug. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

The purpose of this study is to evaluate the effectiveness of a psychosocial intervention called iTEST for people with psychotic disorders that targets introspective accuracy, or the ability to accurately gauge ones abilities. iTEST combines daily cognitive training on a mobile device with coaching that addresses recovery goals. In this trial, we will randomize people to one of two interventions conditions, iTEST or a control condition that receives coaching and cognitive training that does not emphasize introspective accuracy. Both interventions will take place over 12 weeks and participants will be asked to complete assessments at baseline, 6 weeks, 12 weeks, and 24 weeks. The primary outcome of the study is community functioning. Participants will be from three metropolitan areas: San Diego, Dallas, or Miami.
