Filter by:The overarching goal of the project is to determine whether differences in stomach-brain coupling contribute to key symptoms of major depressive disorder (MDD) and whether transcutaneous non-invasive vagus nerve stimulation (tVNS) may serve as a non-invasive intervention to improve aberrant interoceptive signaling in participants suffering from MDD.
The purpose of this study is to decode different thinking states from the brain activation patterns and identify the neural circuits that disengage from these thinking patterns using functional magnetic resonance imaging (fMRI) measurement in individuals with major depressive disorder.
This is an open-label study, in which all participants receives an active treatment with repetitive transcranial magnetic stimulation (rTMS) according to clinical protocol. The aim with this pilotstudy is to investigate the feasibility to perform a trial of low-frequency rTMS on treatment-resistant depression in adolescents. The study includes adolescents 13-19 years old, with average to severe depression.
The purpose of the current study is to perform a unified, homogeneous data collection protocol that includes a large cohort of patients undergoing different treatment options for Major Depressive Disorder (MDD) as an avenue for investigating optimal biomarkers for depression treatments on an individual patient level.
The purpose of this research is to see if information from blood and data from smartwatches can be combined to help diagnose depression and determine if transitions between active depression and treated depression can be predicted.
This is a prospective clinical cohort study of depression. The study was intended to include 300 patients with depression and 100 healthy controls. The study consisted of two phases: the baseline period and the follow-up period, in which all subjects were comprehensively collected, and the follow-up period in which all subjects were followed up at least once a year and data were collected. For patients with major depressive disorder, the follow-up methods included fixed visit and planned visit, and the follow-up time point covered the whole course of depressive disease(baseline, 2nd weekend±7days, 6th weekend±14days, 8th weekend±14days, 12th weekend±14days, Week 14-104 Every 4 weekends ± 14 days). Based on standardized, multi-strategy follow-up system and mobile health technology, long-term follow-up of patients with major depressive disorder was realized, and key nodes of patients' disease fluctuations were captured in time. High quality multidimensional data were collected, including demographic, clinical, EEG and eye movement data. Finally, the objective index system of depression was constructed, and the diagnosis, efficacy/recurrence prediction and suicide warning models of depression were established.
This study apply a wearable visual device (HMD)-VR-based software medical device for patients with depressive disorder for 8 weeks. The investigator would like to confirm evaluate the safety and efficacy of the wearable visual device(HMD)-VR-based software medical device effect of improving depressive disorder in patients.
The perception of the environment through the study of sensory awareness is important to understand the adaptive or symptomatological behaviors (e.g., withdrawal, increased activity level, stimulation seeking, etc.). Sensory processing disorders, such as hypersensitivities or hyposensitivities, have been described in people with depression using the Adolescent Adult Sensory Profile scale. In a recent study, similar results consistent with extreme sensory profiles (hypersensitivity, hyposensitivity, sensation avoidance) in adults with a major depressive disorder were observed. The evolution over time of the sensory profile in people with a depressive disorder is not known. It is currently unknown whether these extreme sensory processing profiles are stable over time or whether they may evolve with the depressive symptomatology to normalize with clinical improvement. This knowledge could have an important impact both on the symptomatological expression of the disorder, its recognition, and also on the management of the patient. The investigators aim to study the evolution over time of the sensory profile of depressed subjects hospitalized using the ASSP. The behavioral responses of individuals with sensory processing disorder may be related to the coping strategies of these individuals with their living environment. In a second step, the investigators will study the second step the sensory profile of subjects with depression according to their coping strategies, their living environment and their clinical characteristics (anxiety (anxiety, psychomotor slowing, self-esteem, anhedonia).
The investigators are studying the feasibility, safety, and tolerability of administering accelerated repetitive Transcranial magnetic stimulation(a-rTMS) at frequencies other than standard 10 Hz for in-patient Subjects diagnosed with Major Depressive Disorder. Participants will be recruited from the Resnick Neuropsychiatric Hospital. This study will enroll 30 participants who will undergo up to three brain activity recordings, one MRI scan, one TMS procedure to determine the appropriate frequency and intensity for treatment, daily symptom assessments, and 25 TMS treatments. Participants will be asked to participate for up to 2 weeks.
Adult Psychiatry Clinic Medical University of Gdańsk (MUG) is a healthcare facility that provides ketamine treatment to adult patients suffering from mental health conditions. The Clinic especially treats individuals suffering from treatment-resistant disorders, like - mood disorders, anxiety disorders, obsessive-compulsive and related disorders, trauma and stressor-related disorders, somatic symptom and related disorders, and dissociative disorders. Herein, this naturalistic observation aims to look at the safety and tolerability of ketamine treatment to further develop the understanding of ketamine in the use of psychiatry.
