Filter by:While treating depression, significant numbers respond poorly to anti-depressants; one cause is vitamin B12 deficiency. The investigators are conducting an open label randomized controlled trial to investigate difference in response to SSRI monotherapy alone versus SSRI and intramuscular B12 replacement in people with low-normal B12 levels. 300 participants will be allocated to each arm of intervention at out patient clinics of the department of Psychiatry at Aga Khan University Hospital, Karachi Pakistan. Baseline and 3 month measurement of depression will be on Hamilton Rating Scale for Depression (Urdu version) and response rates compared.
The purpose of the study is to examine the effects of a form of talk therapy called cognitive behavior therapy (CBT) in the treatment of major depression in individuals with Parkinson's disease (PD).
The aim of this study is to identify genetic, physical (brain) and psychological (cognitive) markers (or combinations of them) that predict specific response to a range of antidepressants treatment (Escitalopram, Venlafaxine, Sertraline) in patients diagnosed with major depressive disorder. This study is focused on outcomes which may impact on how "personalised medicine" is implemented in depression.
This study will evaluate changes in brain gamma-aminobutyric acid (GABA) levels due to treatment with escitalopram in people with major depressive disorder.
The purpose of this study is to test the safety, efficacy and mechanism of action of subgenual cingulate (Cg25) deep brain stimulation (DBS) for major depression in patients who have not responded to prior antidepressant treatments. Participation in the study will continue for ten years or until the device receives FDA approval for depression. Forty (40) patients will be enrolled in this study.
The purpose of this study is to evaluate the effectiveness, safety and tolerability of an escitalopram combination treatment compared to single treatments, and to placebo in patients with major depressive disorder.
The purpose of this study is to assess the safety and feasibility of concurrent treatment of nicotine dependence (cigarette smoking) and acute depression. Participants who meet DSM-IV criteria for both nicotine dependence and acute major depression will be given pharmacological treatment for both disorders at the same time, along with a brief behavioral intervention for smoking cessation.
The purpose of the study is to examine the effectiveness of mifepristone treatment in patients with refractory depression. Refractory depression is defined as clinical depression that is unimproved after treatment with at least 2 different antidepressants of adequate dose and time trial. Mifepristone will augment current medications.
