Filter by:Aripiprazole is a new antipsychotic agent which possesses unique capabilities compared to other antipsychotic agents, especially because of its partial dopaminergic agonistic activity. Moreover, like the other atypical agents, aripiprazole is an antagonist of the 5-HT2a receptor, and an agonist of the 5-HT1a receptor. These pharmacological properties should enable this molecule to provide antidepressant potentiating capabilities based on what has been observed with other compounds sharing similar pharmacological profiles. Aripiprazole is now well recognized for its capacity to potentiate antidepressants in the treatment of unipolar depression. However, two randomized controlled trials of aripiprazole in the treatment of bipolar depression were negative. This surprising result may stem from the fact that the doses of aripiprazole used in these studies were rather high (17.6 ± 8.3 mg/d in study 1 and 15.5 ± 7.5 mg/d in study 2) and could have contributed to inhibit dopaminergic activity in key brain areas involved in the modulation of rewards, motivation and concentration. Bipolar depression is indeed heavily loaded with general symptoms of psychomotor retardation including poor concentration, low energy level, hypersomnolence, and hyperphagia. All these functions are modulated by dopamine and strategies aimed at improving dopaminergic function are used frequently to resolve residual symptoms of bipolar depression. It is expected that aripiprazole used at a more adequate lower dose than in previous studies, should be efficacious in the treatment of bipolar type I depression.
The investigators propose to conduct a 20 week open pilot study of Interpersonal and Social Rhythm Therapy (IPSRT) to treat individuals (n=18) with subthreshold bipolar (BP) who are currently depressed. The investigators will conduct a preliminary evaluation of sleep-wake and social rhythm patterns in study participants using questionnaires and actigraphy. Primary aims of this study are to evaluate feasibility of this treatment and assessment approach. Exploratory aims are to examine 1) sleep-wake and social rhythm patterns in subthreshold BP, 2) impact of IPSRT on symptoms and functioning over time and 3) relationship between sleep-wake and social rhythm patterns and treatment outcomes.
The purpose of this study is to evaluate minocycline as a potential treatment for bipolar depression when added to a mood-stabilizing medication. Minocycline is an antibiotic that is approved for the treatment of infections and acne. Participation in this research study is expected to last 8 weeks, and includes five outpatient visits.
Childhood bipolar disorder- not otherwise specified (BP-NOS) was originally considered to be a milder version of bipolar disorder (BD). Research now indicates that BP-NOS is a highly impairing condition. No pharmacologic treatment guidelines exist for BP-NOS. Available evidence-based pharmacotherapy guidelines are for BP1; efficacious medications are, unfortunately, associated with significant risk for adverse events (Kowatch et al, 2005; 2009). Previous research on diet and nutrition suggests that omega-3 (Ω3) fatty acids have a beneficial effect on mood, which might provide either a primary or adjunctive treatment with a more favorable risk:benefit ratio for children suffering from BP-NOS than currently available pharmacologic interventions. Psychoeducational psychotherapy (PEP) also has shown promise in treating bipolar spectrum disorders in children aged 8-12 (Fristad, 2006; Fristad, Verducci, Walters, & Young, 2009); its efficacy in treating BP-NOS specifically has not been determined. The current study compares Ω3, PEP, and their combination to a placebo supplement and active monitoring (AM) in a 12-week trial of 60 children with BP-NOS (15 each with Ω3, Ω3 plus PEP, PEP, and placebo, all with active monitoring). Primary goals are to determine: 1) feasibility of a) recruiting 60 participants in 2 years; b) participant retention over a 12-week trial; and 2) placebo-controlled effect sizes for Ω3, PEP, and combination treatment on manic and depressive symptoms. Secondary goals are to explore response curves over time, mediators and moderators, treatment response across a broad array of outcome variables, adherence to treatment, impact on physiologic parameters often worsened by mood stabilizing medications, and experience of side-effects in participants receiving Ω3 and/or PEP. Comparisons of results to a parallel study of children with depression with identical design will maximize knowledge gained. This pilot study of Ω3, PEP, and combined treatment will provide evidence about whether a larger trial is feasible and justified.
The study aims to evaluate whether or not an EEG (a type of brain scan) is useful in diagnosing youth with either ADHD, BPD, ASD. Youth with ADHD, BPD, ASD, and healthy controls (without ADHD, BPD, and ASD) will undergo an EEG, and the results will be analyzed using brain activity flow pattern analysis (BAFPA). Twenty subjects with each disorder and twenty without any of the disorders under study (controls) will be evaluated. All subjects will be comprehensively assessed with structured diagnostic interviews and neuropsychological testing. All EEG analyses will be conducted under blind conditions. Conditional probability and receiver operating characteristic (ROC) analyses will examine the diagnostic utility of the EEG scan, using the clinical diagnosis of ASD as the gold standard.
The investigators plan to evaluate the efficacy and safety of intranasal Ketalar (ketamine hydrochloride) in the treatment of primary symptom manifestations of pediatric bipolar disorder; Fear of Harm (FOH) phenotype. This phenotype represents those children who are most resistant to traditional treatments and suffer repeated hospitalizations. Primary symptoms include fearfulness, aggression secondary to threat, mood and/or arousal instability, and psychosis. In addition to evaluation of efficacy and safety, the investigators will also analyze whether therapeutic response depends upon the degree to which the subject fits the FOH phenotype.
The present study aimed at identifying clinical risk factors for switch into (hypo)mania or mixed states, within 8 weeks after introduction of an antidepressant or after increasing its dosage.
Learning includes the ability to generalize to new situations and respond to similar, yet not identical stimuli. In previous work, focused on stimulus generalization in healthy volunteers, tones that were negatively reinforced induce wider generalization curves than tones that were positively reinforced, and these in turn induce wider curves than neutral memory (Schechtman et al, 2010). The current study aimed to evaluate those patterns in different clinical disorders (including Schizophrenia, Bipolar disorder, MDD, Anxiety disorders (Panic and GAD) and PTSD, and healthy subjects that would be used as a control), with consideration whether those patterns are unique to any specific disorder or state. The generalization patterns evaluation would conduct twice though enable to compare the stability of those patterns during the course of the illness (i.e during remission compared to acute state). The basic paradigm based on conditioning of a tone (sound) with unpleasant noise, and extinction of that conditioning afterword. During the 60 minutes of evaluation, the capability to discriminate between the original tone and similar but not identical tones, and the tendency to categorize similar tones as identical to the original tone. A neutral tone without conditioning will be used as reference. The clinical diagnosis will conduct by a senior psychiatrist, and the state would be evaluated using standard questionnaires
This study is designed to describe asenapine prescribing patterns in the United Kingdom (UK) during the post-approval period under conditions of usual practice. The use of asenapine in Bipolar Disorder and other indications will be described. To provide epidemiological and clinical perspective, use of aripiprazole and other comparator drugs will be described.
This study will assess asenapine (Sycrest®) use in participants with bipolar disorder; comparison will be made to the use of risperidone (RISPERDAL®CONSTA®) and olanzapine (Zyprexa®). The occurrence of identified and potential clinically important risks will also be assessed.
