                 The goal of this clinical trial is to learn how hormonal changes over the menstrual cycle affect mood symptoms in reproductive-aged women with depression that worsens during the premenstrual period. The main questions it aims to answer are: --How do fluctuations in estradiol and progesterone across the menstrual cycle affect the ability to experience pleasure and the neural sensitivity to reward in hormone-sensitive, depressed women? And consequently, how does stabilizing the luteal phase decline in estrogen and progesterone (using estradiol patches and progesterone pills) affect these changes? Participants will: - Receive hormones followed by placebo, or vice versa, for a total of four weeks across three menstrual cycles - Complete daily mood ratings - Collect home urine samples for hormone testing - Complete five biobehavioral testing sessions during which neural responses are recorded (via electroencephalography, or EEG) during an acute stress task and computer tasks Type: Interventional Start Date: Sep 2024 |

Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...

                 The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significant symptom reduction and functional improvement from baseline symptom measurements (Visit 3) to 1-week (Visit 7), 4-weeks (Visit 8), and 6-weeks (Visit 9) post dosing. The investigators will recruit individuals with mood, anxiety, trauma, addictive, or related symptomatology, and who have functional impairment associated with these symptoms. A DSM-5 diagnosis is not required (nor is it an exclusion). The investigators will allow for comorbidity and only exclude based on psychological and physiological safety considerations. Critically, this approach will allow us to assess the tolerability of our interventions in individuals who would typically be excluded from efficacy studies due to various comorbid DSM-5 conditions. The investigators will employ an open-label study where participants will be given one dose of oral psilocybin 25mg. The investigators will also have follow-up visits at 1, 4, and 6 weeks and an optional long-term follow-up at 3, 6, and 12 months. Type: Interventional Start Date: Oct 2024 |

                 The overall goal of this study is to map the spatiotemporal dynamics of social affective processing and to examine selective modulation of these dynamics in humans undergoing invasive intracranial monitoring for treatment-resistant epilepsy and depression. Pursuing this signal from a novel platform with invasive intracranial recording electrodes provides much-needed spatial and temporal resolution to characterize the neural dynamics of socio-affective processing. The investigators will leverage first-in-human intracranial neural recording opportunities created by a novel therapeutic platform termed "stereotactic electroencephalography-informed deep brain stimulation" (stereo-EEG-informed DBS), as well as the powerful platform of intracranial stereotactic recording and stimulation in patients undergoing epilepsy surgical evaluation at Baylor College of Medicine. The sEEG-informed DBS trial provides unique opportunities for intracranial recording of affect-relevant network regions in patients with treatment-resistant depression (TRD). Recordings in identical regions in epilepsy patients who themselves often demonstrate mild-moderate depressive symptoms will provide a wide dynamic range across the symptom spectrum. To provide critical data on the spatiotemporal dynamics of socio-affective processing the investigators will leverage these two human intracranial recording and stimulation cohorts to study the precise structural, functional, and causal properties of the affective salience network. Greater understanding of the social processing circuitry mediated by the affective salience network may be used to drive therapeutic innovation, pioneering a new paradigm that improves socio-emotional function across a wide variety of neuropsychiatric conditions. The results from this proposal have the potential to improve the lives of patients with dysfunction in social affective processing, with implications for a wide range of neuropsychiatric diseases.

Eligibility: Adults aged 25-64 with major depression that has not been relieved by current treatments. Design: Participants will be admitted to the NIH Clinical Center for 5 18 weeks over 2 3 treatment phases. Their medications may be adjusted. Participants will be interviewed about their depression, side effects, and other treatments they are receiving. They will complete questionnaires. They will give blood and urine samples. Their brain waves and heart rhythm will be recorded. They will take tests of memory, attention, mental functioning, and thinking. Participants will have magnetic resonance imaging (MRI) scans of the head and brain. They will lie on a table that slides in and out of the scanner. Pictures of brain chemicals will also be taken. They may complete tasks during the MRI. Participants will receive TEST and/or sham treatments. They may receive optional ECT. An intravenous catheter will be placed in an arm vein to receive general anesthesia. Two electrodes will be placed on the front of their head. An electric current will be passed from the ECT machine through the electrodes. For sham treatments, they will not receive the electric current. Their breathing, heart rate, brain function, blood pressure, and body movements will be measured. Participants will have 7 follow-up visits over 6 months. Visits can be done via telehealth. Participation will last for up to 42 weeks. Type: Interventional Start Date: Nov 2022 |

                 This research study seeks to find causes and treatments of depression in teenagers. The study goals are to increase our knowledge of treatments for depression and understand how the brain changes when teenagers have depression. The study will also compare teenagers with depression to those without mental health diagnoses. This outpatient study is recruiting participants ages 11-17 who are depressed. They must have a pediatrician or other medical provider, be medically healthy, and able to perform research tasks. They may not currently be hospitalized, psychotic or actively suicidal. Teenagers with depression are eligible even if they are taking medication. The study begins with an evaluation that includes clinical assessment, interviews, and questionnaires. - Visits may include paper-and-pencil and computer tests of mood, memory, and thinking; specialized computer games; and structural and brain imaging. If eligible, study participants may return several times a year for up to two years. This part of the study does not involve treatment. - Participants may be eligible for outpatient treatment for up to 25 weeks. This includes evidenced-based "talk" therapy. Participants may choose either Interpersonal Psychotherapy for Adolescents (IPT-A) or Cognitive Behavioral Therapy (CBT). If indicated, participants may opt to receive standard medication treatments along with psychotherapy. Research includes computer tasks and brain imaging. All clinical evaluations, research tasks and visits are free of cost. Participants are compensated for research activities. Parents and teenager must agree to the teenager s participation in research. The study is conducted at the NIH in Bethesda, Maryland and enrolls participants from the Washington DC Metro region within 50 miles of NIH. Transportation expenses are reimbursed by NIMH.
