The aim of the following pilot study is to examine boredom in a community sample of adolescents and a clinical sample of adolescents. This is important in order to examine differences among healthy adolescents and adolescents with mental illness.
This study will assess the effectiveness of a combination of buspirone and motivational interviewing therapy in the treatment of marijuana dependence.
The purpose is to study treatments of Seasonal Affective Disorder (SAD).
Comorbid depression has been consistently linked to worse outcomes for patients in substance abuse treatment programs. Practice guidelines recommend pharmacotherapy for comorbid depression if symptoms persist after a 4-week "wash-out" period for detoxification (e.g., Veterans Health Administration; American Psychiatric Association). Medications may be considered earlier if a patient has current symptoms and a history of major depressive disorder (MDD) during periods of sobriety. Current efficacy data suggest that antidepressant medication can improve both depression and substance use outcomes among comorbid patients Guideline-concordant use of antidepressant medication for persons with comorbid substance use and depressive disorders, however, is not routine in many VA substance abuse treatment settings.
The aim of this study is to examine whether resource-oriented music therapy helps psychiatric patients with low therapy motivation to improve negative symptoms and other health-related outcomes.
This study seeks to increase the understanding of dopamine receptor function in the brain during major depressive disorder and bipolar depression, as well as genetic changes that may be behind changes in those receptors' actions. Dopamine is a natural messenger in the brain, involved in reward, motivation, and mood. Volunteers aged 18 to 55 who have primary major depressive disorder and those who have bipolar depression (20 in each group), who are not HIV positive and do not have AIDS, and who are not pregnant or breastfeeding may be eligible for this study. A telephone interview will be held, for patients to answer standardized questions about psychiatric or medical symptoms they may have experienced during their lifetime. Those eligible for the study will undergo interviews and laboratory tests. A psychiatric interview and clinical assessment will collect various data. Patients will undergo the following procedures and tests: - A brief neurological examination - A one-minute electrocardiogram to measure electrical activity of the heart. - Laboratory tests measuring several substances in the blood and urine. - Pregnancy test. A magnetic resonance imaging (MRI) scan will be done to create an image of the volunteer's brain structure. The technique of MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. During the MRI scan, volunteers will lie still on a table that will slide into the scanner for 30 minutes and in some cases up to but no more than 90 minutes. Volunteers will be asked to lie as still as possible during the procedure. Then a PET system will create two images of brain blood flow-one of brain dopamine 1 receptor and one of dopamine 2/3 receptor binding. Volunteers will be given a radiotracer, a tiny amount of a drug that can be detected by a special camera in the PET scanner. A tiny flexible tube will be placed in the vein of one arm during each PET scan but during the MRI scan. Volunteers will be asked to lie still on the PET scanner table. A mask with large holes for eyes, ears, and mouth will be placed over the head, to keep the head from moving. After radiotracer injections are given, the PET scanner will create brain images. There may be two PET scanning sessions, each requiring about 3 hours of scanning. During only one of these there will be breaks. At the end of the scanning session, volunteers will be asked to drink several glasses of water and urinate immediately, to reduce radiation exposure to the bladder wall. Genetic screening will help to enhance researchers' understanding of the role of dopamine receptors in depression. A small blood sample, about 2 tablespoons, will be collected, to isolate DNA from blood cells. Some of the blood samples or DNA may be stored for future studies, but those samples will remain coded, so participants will not be identified. This study will not have a direct benefit for participants. However, the results may provide knowledge to help people in the future. This study does involve compensation.
Recurrent fall/winter major depression (known as Seasonal Affective Disorder (SAD)) is a prevalent and disruptive disorder whose pathophysiological basis is unknown, but several hypotheses attribute a causal role to the circadian timing system. Bright white light exposure via the retina has been shown to reverse the symptoms of SAD. Recent physiological studies demonstrated the existence of retinal ganglion cells capable of transducing light input to the retinohypothalamic tract, the primary circadian afferent in humans. This retinohypothalamic system appears to be maximally sensitive to light in the 446-477nm (violet/blue) range. Using light-emitting diode (LED) technology, light of narrow bandwidths now can be delivered from a safe, relatively inexpensive device. We propose to contrast in SAD patients the efficacy and tolerability of 468 nm LED light from a portable 11cm x 6cm commercially-available device (GoLITEÔ) to a broader 400-700 nm wavelength LED-generated light housed in an identical device. The broad wavelength (white) light from our LED device is similar to that from cool-white fluorescent 10,000 lux devices currently the standard for treatment of SAD (see e.g., Lam & Levitt, 1999). Twenty-four depressed SAD outpatients will be randomized to a 3-week trial of light therapy using either the narrow 468 nm LED source or the broader 400-700 nm LED source, each housed in a GoLITEÔ device. Subjects will be given devices and written instruction for administering daily treatments at home, 45min every (q) a.m. The devices will be described to subjects in terms of wavelength but not specifically described as "blue" or "white." Weekly depression ratings and assessments of adverse effects will be obtained by a trained rater blind to the treatment condition. Depressive symptoms will be rated weekly by the same trained clinician. The following hypotheses will be evaluated: - H1-- Depressed SAD patients will demonstrate greater antidepressant therapeutic benefit from the narrow-wavelength (blue) source than from the broad-wavelength (white) source. - H2-- Depressed SAD patients will manifest fewer adverse effects during treatment with the narrow-wavelength (blue) source than with the broad-wavelength (white) source.
The purpose of this study is to study the effects of nursing home visits in independently living elderly people on their functional performance and health-related quality of life. The general practitioner (GP) can refer elderly people to this intervention model after identification of a problem in cognition, mood, behavior, mobility, or nutrition. A specialist geriatric nurse visits the patients at home up to six times and coaches the patient in cooperation with the GP and geriatrician.
This study will explore possible hormonal causes of menstrual-related mood disorders (MRMD) by stopping the menstrual cycle with a drug called Lupron and then giving in sequence two menstrual cycle hormones, progesterone and estrogen. The study will first evaluate Lupron's effectiveness in treating MRMD and will then examine the effects of giving estrogen and progesterone on mood and behavior. In addition, positron emission tomography (PET) and magnetic resonance imaging (MRI) will be used to study serotonin receptors and transporters - molecules in the brain that are thought to play a major role in mood changes related to the menstrual cycle. Menstruating women between 18 and 50 years of age who are in good health, not pregnant, and not taking medications may be eligible for this study. Women with MRMD must have had at least moderately severe MRMD or behavioral disturbances for at least 6 months within 2 years of entering the study. Healthy controls must have no history of MRMD or behavioral disturbances. Candidates undergo physical and neurological examinations, chest x-ray, electrocardiogram, and blood and urine tests. Results of a recent Pap smear (no longer than 12 months before beginning the study) must be available. Participants undergo the following tests and procedures: - Drug treatment: Lupron is injected into a muscle once a month for 5 months. After the second month, participants receive estrogen or progesterone, or both, daily. Estrogen is delivered through a skin patch (20 micrograms per day) and the progesterone is taken as a rectal or vaginal suppository twice a day for the remaining 12 weeks of the study. Every day, all participants wear a skin patch and insert two suppositories, but at some point during the 12 weeks, active medication is replaced with placebo to allow the drugs to wash out of the body. - Physical examination and blood draw: A physical examination and blood tests are done at the start of the study and several times during the study to assess general health, evaluate liver and kidney function, and measure blood cell counts. - Response to treatment drugs: Responses to Lupron, estrogen, and progesterone are evaluated periodically with interviews and symptoms self-rating scales. Control subjects also take paper and pencil psychological tests. - PET imaging: A total of six PET scans are done at three time points during hormone treatment. PET uses small amounts of a radioactive chemical called a tracer that "labels" active areas of the brain. For the procedure, the subject lies on the scanner bed. A special mask is fitted to the head and attached to the bed to help keep the subject's head still during the scan so the images will be clear. A brief scan is done just before the radioactive tracer is injected to help in analyzing the PET data. After the tracer is injected through a catheter (plastic tube) placed in the arm, pictures are taken for about 2 hours, during which the subject lies still on the scanner bed. - MRI scan: MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the patient lies on a table that is moved into the scanner (a narrow cylinder) and wears earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure lasts about 1 hour.
