Effectiveness

How Seroquel Xr Affects Patients

Quetiapine works by affecting certain brain chemicals (like serotonin and dopamine) to improve the symptoms of schizophrenia, depression, and bipolar disorder. However, this drug has been linked to suicidal thoughts or behavior in children and adolescents and should not be given to those under 10 years old. It is important to be aware of any signs of suicidal behavior when taking this drug. Also, it is not recommended for treating psychosis related to dementia in elderly patients as it can increase their risk of death.

How Seroquel Xr works in the body

Quetiapine targets several receptors in the body to treat different conditions. For schizophrenia, it inhibits dopamine and serotonin receptors. In depression, it binds to the norepinephrine transporter. Other effects, such as drowsiness, low blood pressure, and dry mouth are caused by blocking H1, adrenergic alpha-1, and muscarinic M1 receptors respectively.

Seroquel Xr Reviews: What are patients saying about Seroquel Xr?

Patient Review

Seroquel Xr for Additional Medications to Treat Depression

I took Seroquel XR in conjunction with Amitriptyline for approximately 20 years to address my depression. This combination worked well for me until last year when my nurse practitioner increased my dosage of Seroquel XR to 400 mg and took me off amitriptyline. I've had great results with this new treatment plan, except for issues with night sweats and constipation. For the latter problem, I take magnesium supplements.

Seroquel Xr for Bipolar Depression

This medication has been a life-changer for me. It helps with my anxiety without making me feel sedated or dumb. I feel calm and my social anxiety goes away. It's a miracle drug and, in my opinion, one of the best medications out there.

Seroquel Xr for Bipolar Depression

I'm pretty content with this drug. No real negative side effects that I've notices, though it doesn't quite treat my depression entirely. Additionally, it can make me a bit groggy in the morning if I haven't had enough sleep, but that's manageable. All things considered, I would recommend this to others in a similar situation to myself.

Seroquel Xr for Bipolar Depression

This medication has been great for me. I only had one depressive episode in the year that I've been taking it, and was able to work through it without help from my psychiatrist. Additionally, there have been no side effects like weight gain or sedation.

Seroquel Xr for Mania associated with Bipolar Disorder

I took this medication for seven years before quitting cold turkey. Unfortunately, that led to some pretty severe manic episodes that landed me in jail. Since then, I've been more careful about monitoring my mental health and taking other medications as needed. If you're considering stopping this medication, please be very cautious and aware of potential changes in your behavior.

Seroquel Xr for Schizophrenia

I've been taking Seroquel XR 800mg for over a decade now. It's done wonders for my thought process and sleeping patterns. However, I have experienced hives as a side effect, which requires me to take additional medication. Additionally, I've noticed male gynecomastia developing.

Seroquel Xr for Manic-Depression

I would only recommend this drug to someone who is terminally ill, because the withdrawal effects are absolutely nightmarish. I would advise anyone considering taking this drug to do their research and read about Seroquel withdrawal – it’s not worth it.

Seroquel Xr for Bipolar I Disorder with Most Recent Episode Mixed

I've been taking this medication for a while now, and it's honestly made my quality of life worse. I'm constantly exhausted, to the point where even getting out of bed is a challenge. This has put a strain on all my relationships. Thankfully, I'm switching to a different medication that hopefully won't be so debilitating.

Seroquel Xr for Additional Medications to Treat Depression

I was really exhausted when I took this drug, and it made me gain weight- I'm the heaviest I've ever been. Additionally, it caused sleepwalking; at one point, I woke up in the backyard. Overall, not a great experience for me.

Seroquel Xr for Mania associated with Bipolar Disorder

Ten minutes after taking just one pill of this medication, I completely lost control of my body and mind. I was screaming and shaking uncontrollably, according to witnesses, and have no memory of the event. The doctors insist that this isn't a side effect of the drug, but I beg to differ.

[18F]MK-0947 for Parkinson's Disease

18 - 80
All Sexes
New Haven, CT

This clinical study is being conducted to learn more about a new imaging drug called \[18F\]MK-0947, which is designed to help doctors see changes in the brain related to Parkinson's disease (PD). PD is a condition that affects movement, balance, and thinking. The drug works with a type of scan called PET (Positron Emission Tomography) to show areas of the brain where a protein called α-synuclein builds up. This buildup is linked to PD and other brain disorders. The main goal of this study is to find out if \[18F\]MK-0947 is safe for people and if it works well to show α-synuclein in the brain. The study will also look at how the drug moves through the body and how much radiation it gives off. Researchers hope this information will help develop better tools for diagnosing PD and tracking how it changes over time. Who can join? Adults who have PD or who are healthy may be able to take part. Participants will have screening tests to make sure they qualify. What does participation involve? People in the study will have PET scans, blood tests, and other safety checks. Some participants will also have an MRI scan. The study is divided into two parts: Part 1 looks at how the drug works in the brain of PD patients and healthy elderly participants, and Part 2 measures radiation levels in healthy participants. Why is this important? There is currently no cure for PD, and better imaging tools could help researchers develop new treatments. By joining this study, participants will help advance research that may improve care for people with PD and similar conditions in the future.

Stanford, CA

The current study aims to test the feasibility of a new form of group therapy for women who have a history of interpersonal trauma and current suicidal ideation. The Building Empowerment and Resilience (BEAR) Therapeutic group has been adapted for women who have experienced trauma and have current suicidal ideation. It incorporates psychological skills, psychoeducation about trauma and gender-based violence, and physical self-defense training, all within a therapeutic process. It will be implemented with women who have experienced interpersonal trauma (physical, sexual, or emotional abuse/neglect) and experience various mental health difficulties, including suicidal ideation. We aim to assess the feasibility to recruit and implement the BEAR group. Our ultimate aim is to assess whether the program can effect self-efficacy and suicidal ideation.

Cognitive Remediation for PTSD

18 - 45
All Sexes
Montreal, Canada

The goal of this clinical trial is to evaluate whether computer-based brain training can help adults with post-traumatic stress disorder (PTSD). Individuals with PTSD often experience difficulties with memory, attention, concentration, and problem-solving, which can significantly affect their daily lives, work performance, and overall quality of life. These cognitive challenges can hinder trauma recovery and reduce the effectiveness of standard PTSD treatments. The main questions this study seeks to address are: Does specialized brain training improve PTSD symptoms compared to regular computer games? Does brain training enhance cognitive functions such as memory, attention, processing speed, and executive functioning? Does brain training improve quality of life and daily functioning? Do participants' self-efficacy and perceived social support influence treatment outcomes? Researchers will compare two approaches: a specialized cognitive training program (HAPPYneuron Pro) with strategy teachings and quality-of-life discussions, versus engaging computer games with quality-of-life discussions, to determine which is more effective for people with PTSD. Study Design Participants will be randomly assigned to one of two groups for an 8-week program: Cognitive remediation training group: Complete computerized cognitive exercises and strategy teachings specifically designed to strengthen memory, attention, and executive functions, combined with quality-of-life discussions. Control group: Complete engaging computer games combined with quality-of-life discussions. Schedule Both groups will follow the same schedule: One online session per week, in small and consistent groups of 6 participants. Each 60-minute session consists of 30 minutes of computer activities followed by 45 minutes of group discussion. One at-home individual homework exercise per week (30 minutes at home). Total time commitment: 1h45 per week for 8 weeks. Assessments All participants will complete three comprehensive assessment sessions: before treatment, immediately after the 8-week program, and 3 months later. Assessments include neuropsychological testing and questionnaires on PTSD symptoms, depression, anxiety, quality of life, satisfaction with life, social support, cognitive failures, and self-efficacy. Significance This research evaluates a new, accessible and remotely deliverable approach for PTSD treatment. Current evidence-based treatments often do not directly target the cognitive impairments experienced by many individuals with PTSD. Compensation Participants will receive $35 for each completed assessment (maximum $105). Control group participants will gain access to the cognitive remediation training program after completing their participation.

Atlanta, GA

The goal of this clinical trial is to investigate the efficacy of 3,4-methylenedioxy-methamphetamine hydrochloride (MDMA) combined with Massed Prolonged Exposure (PE) therapy for the treatment of posttraumatic stress disorder (PTSD) in adult participants diagnosed with PTSD. This randomized, placebo-controlled trial will enroll 95 participants. The main questions it aims to answer are: * Does the combination of PE + MDMA lead to greater reduction in PTSD symptom severity from pre-treatment to one-month follow-up compared to PE + placebo? * Does PE + MDMA improve response efficiency and durability of PTSD symptom improvement compared to PE + placebo? * Does MDMA + PE enhance extinction retention and reduce amygdala threat reactivity, and are these changes associated with improved PTSD outcomes? Participants will: * Receive 10 sessions of Massed Prolonged Exposure therapy over two weeks * Be administered either 100 mg of MDMA or a placebo at Visit 2 * Undergo blinded independent evaluator assessments using the Clinician-Administered PTSD Scale for DSM-5-R (CAPS-5-R) at the one-month posttreatment follow-up
