Filter by:The primary aims of this study are to: 1. Quantify serotonin transporter (5-HTT) binding potential (BP) in vivo in bipolar disorder patients (BPD) during a major depressive episode (MDE). 2. Assess the effect of lithium treatment of bipolar disorder on 5-HTT. 3. Assess the effect of lithium treatment of bipolar disorder on 5-HT1A BP. 4. Assess the effect of lamotrigine treatment of bipolar disorder on 5-HTT and 5-HT1A BP. 5. Assess the effect of lithium treatment of unipolar depression on 5-HTT BP.
The purpose of this study is to explore whether asking participants to visualise a secure attachment figure or a neutral event leads to differences in self-reported felt security or depressed mood. Furthermore, the investigators aim to explore whether it is possible to keep a secure prime activated over 3 days via text message visualisation tasks.
The aim is to investigate the effect of transcranial Direct Current Stimulation (tDCS) applied at the anodal left CDLPF of patients with resistant depression compared to patients treated with conventional therapy. The tDCS is used in add-on drug treatment in resistant depression stabilized for 4 weeks (antidepressant as SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonine-Norepinephrine Reuptake Inhibitors) for unipolar patients and lithium for bipolar patients). The delay of 4 weeks is a minimum to observe a non-response. Moreover, in term of ethical point of view, it's difficult to wait 6 to 8 weeks to observe the non-response to treatment. This is a randomized 2-arm parallel, double blind study comparing 2 groups of 60 patients (48 unipolar plus 12 bipolar patients per group. Patients will be selected in the psychiatric department of the University Hospital of different centers and the two groups are matched for age (+/- 5 years), gender and depression diagnosis (unipolar vs bipolar). After giving informed consent, patients will be evaluated by a psychiatrist using the Hamilton Depression Rating Scale (HDRS), Montgomery Asberg Depression Rating Scale (MADRS), the STAI and Beck Depression Inventory (BDI) and for bipolar patient only, by the Young Mania Rating Scale (YMRS). The complete assessment takes 50 minutes. A neuropsychologist assessment will be also realized during 20 minutes using the Crossing of Test (COT), the Trail Making Test (TMT), the Isaacs Set Test (IST) and the Cardebat fluency Task. After locating the left DLPFC, treatment with active tDCS with a current of 2 mA or sham will be directed by 30-minute session. A psychometric assessment will be conducted again at the end of treatment week and 4, 12 and finally 24 weeks after stopping treatment. The neuropsychologist assessment will be conducted again 4 weeks after the end of treatment. Scales of comfort and acceptability will also be proposed to the patient to determine whether any gene is caused by this treatment. These people will be recruited on a voluntary basis, after notification and consent in the 6 research centers. This study was conducted over a period of 36 months. This study was supporting by a grant from the French Hospital Program of Clinical Reseach (PHRC N/2011-60-2011-A01074-37)
A single center, open label study assessing the feasibility, safety and therapeutic effect of Minocycline in adult patients with diagnosis of unipolar depression. Up to 30 patients diagnosed with unipolar depression that are in a current depressive episode. The patients will be of all racial, ethnic and gender categories, ranging from 18 to 68 years of age, and have HDRS-21≥20. All subjects will continue to take their treatment with antidepressant medications for the duration of the study. All subjects are prescribed minocycline 200 mg/day orally (2X100 mg) for the first 3 days. than, all subjects are prescribed minocycline 400 mg/day orally (2X200 mg) from day 4 until termination visit (day 35). The primary objective of this study is to assess the therapeutic effect of Minocycline in unipolar depression. The secondary objectives of this study are to assess the therapeutic effect, the feasibility and safety of Minocycline in unipolar depression.
Transcranial direct current stimulation (tDCS) is a novel treatment approach for depression that has shown promising efficacy in four recent double-blind, randomized, sham-controlled trials (RCT) and a meta-analysis. This study is a RCT of tDCS in depressed patients, testing its efficacy in both unipolar and bipolar depression. Mood, cognitive test performance and biomarkers will be measured during the trial.
To demonstrate the efficacy of multiple applications of Low Field Magnetic Stimulation (LFMS) as an antidepressant treatment in subjects with mood disorders.
The purpose of the study is to investigate whether neurofeedback delivered via functional magnetic resonance imaging signals can be used to train depressed patients to self-regulate emotion networks and whether this improves clinical symptoms.
The investigators are adapting Interpersonal Psychotherapy (IPT-A) for adolescents who are referred to emergency services either for a suicide attempt or for being evaluated as high risk for suicidal behavior. The investigators will recruit 15 adolescents ages 12-19 years who present with a diagnosis of major depression, dysthymic disorder, depression disorder not otherwise specified who have a history of a suicide attempt in the past 2 months or a non-medically lethal attempt that may require psychiatric hospitalization, suicide attempt that is or report current suicidal ideation with a plan/intent, and treat them in an open clinical trial. The treatment will be conducted twice weekly for the first 8 weeks of treatment and then weekly for the remaining 12 weeks of the study. Using feedback from clinicians and participants, the investigators will make further modifications to the manual in preparation for conducting a larger controlled clinical trial.
The Clinically Useful Depression Outcome Scale (CUDOS) is a brief, self-administered instrument that not only evaluates depressive symptoms but also both functioning and quality of life. The assessment of patients´ perspective may provide valuable information that could be lost if relaying only on clinician evaluation. The purpose of this study is to achieve a psychometric validation into Spanish of the CUDOS scale in patients with major depression disorder in a primary care setting.
Background: - Medications to treat major depression act on a brain chemical called serotonin, which binds to receptors on brain cells. More research is needed on how serotonin receptors work in the brain, and imaging studies such as magnetic resonance imaging (MRI) can provide information on how these receptors function in the brains of individuals with depression and healthy volunteers. The experimental radioactive chemical [11C]CUMI has been designed to react with serotonin receptors, and researchers are interested in studying its effectiveness using positron emission tomography (PET) scanning to see how well it gets into the brain. Objectives: - To evaluate the effectiveness of the radiotracer [11C]CUMI in brain imaging studies of serotonin receptors. Eligibility: - Individuals between 18 and 55 years of age who either have been diagnosed with major depressive disorder or are healthy volunteers. Design: - Participants will be screened with a full medical history, physical and psychiatric examination, blood and urine tests, and questionnaires about mood. Participants will also have an electrocardiogram at this visit. - At the first study visit, participants will have a MRI scan of the brain to provide baseline data on brain function. - At the second study visit, participants will have a PET scan with the [11C]CUMI contrast agent. - No treatment will be provided as part of this protocol....
