Filter by:The purpose of this pilot study is to investigate and compare the effect of a mild inflammatory stimulus (typhoid vaccine) on immune response, mood and cognition in healthy volunteers compared to patients with history Major Depressive Disorder (MDD) (not currently depressed and no symptoms of depression in the past 6 months).
Among the major depressive disorder (MDD) patients in the follow-up group, 16 were administered with 50 mg of oral sertralin once daily with placebo, whereas 28 were treated with 100 mg of ketoprofen once daily as adjuvant treatment for MDD. Controls do not take any medicine.
Transcranial magnetic stimulation (rTMS) is an investigational and therapeutic modality that impacts the connection strength between neurons by delivering patterned energy. In response to this patterned energy neurons fire and adapt by changing their connection strengths. This change in connection strengths is believed to be the underlying mechanism whereby this intervention has therapeutic benefit for this intervention in conditions such as depression. The purpose of this study is to test a means of enhancing the effect of rTMS using a medication (cycloserine) that has been shown to augment and stabilize activity dependent neuronal changes. The investigators wish to use the motor system, where the associated muscle response to brain stimulation can be measured, to probe activity dependent changes in connection strength between neurons.
HYPOTHESIS: Pregnenolone administration will be associated with greater reduction in depressive symptom severity than placebo in women with current mMDD. STUDY AIMS: Primary Aim: Determine if pregnenolone is associated with greater reduction in depressive symptom severity than placebo in women with mMDD, as measured by MADRS. Secondary Aims: 1. Determine if pregnenolone is associated with greater reduction in anxiety symptom severity than placebo in women with mMDD. 2. Determine if pregnenolone is associated with greater improvement in cognition than placebo in women with mMDD. 3. Determine if pregnenolone is associated with greater improvement in quality of life than placebo in women with mMDD. 4. Determine if pregnenolone is associated with greater improvement in vasomotor symptoms of menopause than placebo. Mechanistic Aims: 1. Determine whether changes in neurosteroid levels with pregnenolone mediate clinical response. 2. Determine if baseline neurosteroid levels predict pregnenolone response. 3. Determine whether depressive symptoms, anxiety, sleep or vasomotor symptoms improve first. A crossed-lagged panel model will explore serial correlations between changes in outcome measures.
The objective of this study is to compare the rate and extent of absorption of paroxetine hydrochloride 20 mg tablets (test) and Paxil® (reference) administered as 20 mg tablet under fed conditions.
Major depressive disorder is the number one cause of disability worldwide. Evidence regarding the effectiveness of various treatments for patients with severe depression is still lacking. Although many patients achieve treatment response, only a minority of patients achieve full remission and even fewer sustain it. In fact, within one month 10% will be re-hospitalized and the rate climbs to 30% within a year. Further, remission from depressive symptoms is a surprisingly poor predictor of recovery of community functioning following discharge. It is clear that the traditional focus on diagnostic symptoms is insufficient for promoting a full return to everyday functioning. The present aim is to examine the efficacy and effectiveness of treating neurocognition, a symptom that explains persistent deficits in community functioning for those with depression. The study design that maps on to the contemporary clinical setting, in order to reflect the changing landscape of inpatient and community treatment.
The proposed study addresses a gap regarding the need for effective Major Depressive Disorder (MDD) treatments and the 40% of individuals treated with antidepressant medications that do not achieve full remission. This study tests a novel approach for treating MDD in a Randomized Control Trial (RTC) using yoga versus walking interventions to correct an imbalance in the Autonomic Nervous System; an over active Sympathetic Nervous System (fight or flight) an underactive Parasympathetic Nervous System (PNS) (rest, renewal and social engagement) and associated under activity in the neurotransmitter, gamma aminobutyric acid (GABA). This novel approach is complimentary to the use of antidepressant medications that primarily target the monoamine systems. Low activity in the PNS and GABA systems are also found in MDD, PTSD, and Alcohol Use Disorder, disorders representing a high healthcare burden in the Veteran population. This intervention has potential to provide relief for MDD and other disorders relevant the Veteran population
This study is a multicenter, randomized, double-blind, placebo-controlled trial designed to assess the efficacy and safety of brexpiprazole as adjunctive therapy in the treatment of Major Depressive Disorder. A total of approximately 1100 subjects will be enrolled into the single-blind treatment for 6 weeks, and 480 incomplete responders will be randomized to brexpiprazole (2~3 mg) or placebo in a 1:1 ratio (approximately 240 subjects in each group), for treatment of 6 weeks.
The investigators will evaluate the efficacy of a 2 various contingency management (CM) interventions (High-Magnitude CM, Shaping CM) for treating heavy drinking among individuals with serious mental illness and alcohol dependence who are seen within the context of a community mental health center setting. Participants will be 400 adults diagnosed with serious mental illness and alcohol dependence and those who demonstrate heavy drinking during the first 4 weeks will be randomized to receive treatment conditions.
This randomized trial with a crossover design will examine the efficacy of rTMS targeting the dorsomedial prefrontal cortex as a treatment for medication-resistant major depression in patients meeting diagnostic criteria for borderline personality disorder.
