Filter by:This study will assess the effectiveness of cognitive behavioral therapy (CBT) in treating seasonal affective disorder (SAD), commonly called the "winter blues."
A placebo controlled study evaluating the effectiveness of medication in preventing winter depressive episodes in patients with a history of Seasonal Affective Disorder
The purpose of this study is to evaluate the effectiveness of a Multifamily Psychoeducation Group for the families of children with mood disorders.
A Placebo Controlled Study Evaluating The Effectivess Of Medication In Preventing Seasonal Affective Disorder
This is a placebo controlled study evaluating the effectiveness of medication in preventing depressive episodes in subjects with a history of Seasonal Affective Disorder (SAD).
The purpose of this study is to determine the safety and efficacy of topiramate in adolescents with manic or mixed episodes of Bipolar I Disorder.
The purpose of this study is to evaluate the function of certain brain chemicals and receptors in patients with mood disorders. This study will also examine how the stress hormone cortisol affects brain function. Data suggest that serotonin 1A (5-HT1A) receptor function is abnormal in patients with mood disorders, such as major depressive disorder (MDD) and bipolar disorder (BP). However, these data are limited because they are based on small sample sizes. In this study, PET scans will be used to compare 5-HT1A receptor binding potential between mood disorder patients and healthy volunteers. All participants will have an initial medical and psychiatric evaluation. Depression severity, anxiety, negative thinking, level of functioning, intelligence, and cognitive functions will be measured. Urine, saliva, and blood will be collected. Women will have a pregnancy test and tests to determine menstrual phase and time of ovulation. Participants will undergo magnetic resonance imaging (MRI) and PET scans of the brain. Some participants will have other procedures such as a lumbar puncture. Participants with Cushing's disease will undergo imaging as a comparison group.
The purpose of this study is to use brain imaging technology to compare how the brains of adolescents and adults are activated during tasks that involve emotional responses. Evidence suggests that adolescents and adults experience activation in similar brain regions when they engage in tasks that involve the processing of emotional stimuli. However, the degree of task-associated activation may differ between adolescents and adults. This study will use functional magnetic resonance imaging (fMRI) to compare brain activation patterns in adolescents and adults. This study will also be used to develop emotion-evoking fMRI tasks to determine whether there are puberty and age-linked components of brain development.
The purpose of this study is to determine what dose of a new timed-release tablet of the drug propranolol will reduce secretion of the hormone melatonin in healthy volunteers. This study will also determine whether suppressing melatonin will improve depressive symptoms in people with seasonal affective disorder (SAD). SAD (sometimes referred to as winter depression) is a condition in which people experience depression as a result of seasonal variations in light. Human brains have a circadian pacemaker that regulates many body functions. As the seasons change and light duration varies, the circadian pacemaker regulates seasonal behavior by transmitting a signal of day length to the pineal gland, which secretes the hormone melatonin. Melatonin secretion increases in the winter as the duration of light decreases. Evidence suggests that the melatonin signal of seasonal change is present in people with SAD but not in healthy volunteers; thus there is a possibility that seasonal changes which influence the duration of melatonin secretion control the course of illness in individuals with SAD. This study will determine whether propranolol can shorten the duration of melatonin secretion and mimic the effect of summer days to improve symptoms of depression in people with SAD. Healthy volunteers will be admitted to the hospital for about 2 days. The volunteers will receive either propranolol or placebo (an inactive pill) before going to bed and upon awakening. Blood samples will be collected at various times throughout the study. Participants with SAD will be interviewed periodically on an outpatient basis to determine the onset of depression in the fall or winter. Two weeks after depressive symptoms arise, participants will begin treatment with either propranolol or placebo. At the beginning of the treatment, participants will be hospitalized for about 2 days and will have blood collected at various times. During the hospital stay, participants will continue treatment with either propranolol or placebo in the morning and at night; all participants will receive propranolol at some point during the study. Participants will be interviewed weekly for 4 weeks. Premenopausal women with or without SAD will keep a record of their menstrual cycles and will use a urine test kit to identify the time of ovulation during the month before and after admission to the hospital.
We are offering non-pharmacologic therapy for alleviation of symptoms associated with depressed mood that recurs annually in fall or winter. The treatments are self-administered at home by the patient, with close clinical supervision. Our trials use specially designed devices that replenish two different environmental elements, naturally occurring light and negative ions in the air. Both factors may be reduced in winter, bringing on depression.
