Development of Magnetic Resonance Imaging Techniques for Studying Mood and Anxiety Disorders
Mood DisordersAnxiety DisordersThis study is intended to help develop new MRI imaging techniques for studying mood and anxiety disorders. Researchers believe that depression and anxiety disorders may cause structural and functional changes in the brain. This study will optimize the way MRI scans are collected to look at brain structure and examine how the brain behaves while subjects perform particular tasks. Healthy normal subjects between 18 and 50 years of age who have never had a major psychiatric disorder and who have no first-degree relatives with mood disorders may be eligible for this study. Candidates are screened by phone with questions about their psychiatric and medical history, current emotional state and sleep pattern, and family history of psychiatric disorders. Candidates who pass the preliminary screening then undergo additional screening interviews and laboratory tests. Participants undergo magnetic resonance imaging (MRI) and neuropsychological testing, as follows: "<TAB>MRI scans: Subjects are asked to participate in an MRI study on one of several scanners to measure blood flow in the brain, concentrations of certain chemicals in the brain, or magnetic properties of the brain. MRI uses a strong magnet and radio waves to obtain pictures of the brain. The subject lies still on a narrow bed with a metal coil close to the head. For this study, subjects may be asked to wear a special coil on the neck to help measure blood flow. They may be asked to watch a screen presenting images or to do a task in which they respond to pictures or sounds and may be asked to return for additional scans. "<TAB>Neuropsychological testing: Subjects may undergo tests of cognitive performance. Often, people with mood disorders have subtle changes in performance on these tests that allow researchers to pinpoint where brain abnormalities occur. Before the tests can be used in patients, they must be validated by using healthy subjects. These tests are presented either orally, in written form, or on a computer.
Clinical Validation of Samsung Smartwatch
Major Depressive DisorderMood Disorders1 moreObjective: Wearable technology holds promising potential for mental health monitoring and detection. Samsung has developed an algorithm that they believe can detect signs of depression and anxiety in smartwatch users. They have used this algorithm to create a "Mindfulness Index," which is an easily understood visual index of mental health. The primary aim of the study is to evaluate the performance of Samsung's Mindfulness Index in identifying those who have received a diagnosis of Major Depressive Disorder (MDD) from a clinician-administered semi-structured diagnostic interview. Research Procedures: The target sample size is 75 individuals diagnosed with current Major Depressive Disorder and 75 healthy controls. To meet this target, the recruitment target is set at 215 participants. Participants will be assigned to the MDD condition, or the healthy control condition based on their score on the Beck Depression Inventory. Each subject will be followed for 3 months. Participants will be provided with a Samsung smartphone and Samsung smartwatch. Participants will be asked to wear the smartwatch 24 hours per day, except while charging. This smartwatch will collect data on heartrate, sleep time, and step count. During the study, each day participants will receive texts prompting a link to a "daily diary." These surveys will ask about depression and anxiety symptoms. Additionally, during the first 3 weeks of the study, participants will participate in ecological momentary assessment; texts will be sent 5 times per day prompting participants to fill out a survey about how they currently feel in that moment. These extra surveys will stop after the first 3 weeks of the study, but the daily diary surveys will continue throughout the study. Furthermore, virtual clinician visits will occur at weeks 4, 8, and 12.
Evaluation of Patients With Mood and Anxiety Disorders and Healthy Volunteers
Mood DisordersAnxiety Disorders3 moreThe purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols....
Early Detection of Alzheimer's Disease and Affective Disorders by Automated Voice and Speech Analysis...
Neurocognitive DisordersPLATA aims to develop an algorithm to identify vocal biomarkers of Alzheimer's dementia. Using data collected as part of routine care, speech patterns will be compared to known biomarkers of Alzheimer's disease, such as amyloid 1-42 and p-Tau in CSF (cerebrospinal fluid). If biomarkers of speech can be identified in Alzheimer's disease, it is possible that patients and research participants will no longer need to undergo need to undergo the intensive and invasive baseline biomarker methods currently used, such as lumbar punctures and PET scans.
Long-term Observation of Participants With Mood Disorders
DepressionSuicide RiskBackground: More than 12,000 people have taken part in research at the Experimental Therapeutics & Pathophysiology Branch at the National Institute of Mental Health Intramural Program. This has led to advances in the treatment of depression, bipolar disorder, and suicide risk. Researchers want to follow up with this group to see if they continue to have mental health symptoms and receive psychiatric treatments. Objective: To learn the long-term impact of depression, bipolar disorder, and suicide risk. Eligibility: Adults ages 18 and older who signed consent for Protocol 01-M-0254 over a year ago. Design: This study has 2 phases: an online phase and a telephone phase. It has no in-person or face-to-face contact. In Phase 1, participants will fill out online surveys. They will access the surveys through the study website. The questions will focus on their current thoughts and feelings. The surveys will also ask about their current treatments for their mental health symptoms. At the end of the surveys, they will be asked if they would like to take part in Phase 2. If so, they will mark yes. Phase 2 includes a phone interview. They will be contacted by email to schedule the interview. In Phase 2, participants will be asked more in-depth questions about how they are feeling. They will also be asked which psychiatric medicines and treatments they have used since they left NIH. In both phases, participants can skip any questions they do not want to answer. The online surveys will take 30 minutes to complete. The phone interview will last 1-4 hours. The information that participants give in this study may be linked to their other NIH research records.
Family Study of Affective and Anxiety Spectrum Disorders
Mood DisordersSleep Disorders1 moreThis study will examine how depression, anxiety, and migraine run in families. It will help in defining the risk factors for physical, mental, and health problems-as well as define ways that those problems may be prevented and treated. A broad range of ages among family members will be included to evaluate the patterns of how these disorders are expressed throughout people's lives. Children of all ages will be included, and those ages 8 to 17 will be interviewed directly. Assessments will be collected through criteria of the Diagnostic and Statistical Manual of Mental Disorders IV as well as the spectrum, or range, of mood disorders and co-existing conditions. A member of the study team will visit the participants at home or will do an interview by telephone. Participation will take approximately 3 to 4 hours. Children will complete questionnaires given by the research team as well as questionnaires that they will do by themselves. The questions will pertain to the children's health, including physical and mental health and medical history, social relationships, problems, skills, and ways of dealing with important or stressful issues in their lives. These questionnaires will take up to 1 hour to complete. Health history gathered from adult participants will pertain to height, weight, exercise, and general function. Women will be asked about the use of oral contraceptives, estrogen, and progesterone. In addition, there will be questionnaires on personality and temperamental traits, that is, behavior and impulsiveness. Questions will also involve social intuition, family and other environmental factors, general functioning, and basic demographics such as ethnicity, race, socioeconomic status, marital status, education level, and employment history. Families enrolled in this phase of the research will be invited to participate in the next phase. There would be follow-up to evaluate the development of mood disorders, subtypes, and syndromes across the lifespan.
Using 18F-FPEB PET to Identify mGLUR5 Availability in Affective Disorders
Major Depressive DisorderBipolar DisorderEvidence suggests that mGLUR5 availability may play a key role in the biology of mood disorders. This study aimed to investigate the changes in metabotropic glutamate receptor 5 (mGLUR5) availability and clinical symptoms in patients with MDD and bipolar disorder(BD) after two months of vortioxetine treatment. The investigators hypothesized that patients with MDD and BP have abnormal mGluR5 availability in certain brain regions, and baseline mGLUR5 availability can predict prognosis the prognosis of MDD and BD. fMRI and NODDI are also used to evaluate the function or neurite condition at baseline and 8 week
Peripheral Immune System in Individuals With Schizophrenia
SchizophreniaSchizo Affective Disorder1 moreThe investigators are seeking healthy volunteers and people with schizophrenia or schizoaffective disorder for a clinical study of the immune system in psychotic disorders. This is an observational study, to understand the ways in which the immune system may be contributing to the disease process.
Study of Premenstrual Syndrome and Premenstrual Dysphoria
Mood DisorderThe purpose of this study is to identify and describe the symptoms of premenstrual syndrome (PMS). Women who experience PMS symptoms will complete clinical interviews, self-rating scales, and evaluations of mood and endocrine function. A subgroup of women with severe PMS (Premenstrual Dysphoric Disorder or PMDD) will be offered additional research studies that focus on: 1) identifying the endocrine changes that may be responsible for changes in mood and behavior during the premenstrual period, 2) evaluating treatments for PMS symptoms, and/or 3) identifying genetic factors in women with and without PMS. Women with recurrent brief depression will also be recruited to serve as a comparison group.
The Place of Consultations Specializing in the Diagnosis of Mood Disorders in Strasbourg University...
Mood DisordersMood disorders (depressive disorders and bipolar disorders) are among the ten most worrying diseases of the 21st century according to the WHO. In order to support psychiatrists in their diagnostic reflection, structures have been created. Since 2009, the Psychiatry Service 2 within the Psychiatry, Mental Health and Addictology Pole of the University Hospitals of Strasbourg has offered specialized consultations in mood disorders. More than 10 years after the creation of these consultations, it seems interesting to study the profile of the users and to describe the nature of the reports of these in-depth evaluation consultations (diagnosis, therapeutic advice)
