EEG Microstate and Neuroinflammatory Biomarkers in Older Age Patients With Major Depressive Disorder Receiving ECT

This study aims to investigate the neurophysiological and inflammatory changes associated with electroconvulsive therapy (ECT) in older age patients diagnosed with Major Depressive Episode, Major Depression, and Bipolar Disorder, using microstate analysis derived from resting-state electroencephalography (EEG) recordings. Within this scope, EEG recordings obtained before and after ECT will be compared to determine the relationships between changes in microstate parameters and inflammatory marker levels, clinical variables, and psychometric scale scores reflecting clinical improvement. Peripheral blood samples collected from the same patient group will be analyzed for complete blood count parameters as well as levels of interleukin-1 alpha (IL-1α), interleukin-1 beta (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), soluble glycoprotein 130 (sgp-130), soluble interleukin-6 receptor (sIL-6R), interferon gamma-induced protein 10 kDa (IP-10), and C-reactive protein (CRP). In addition, inflammatory indices, including the Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Monocyte-to-Lymphocyte Ratio (MLR), will be calculated. The association between baseline levels of these biomarkers and treatment response will be evaluated. Moreover, changes in biomarker levels following ECT will be statistically examined in relation to clinical scale scores and EEG microstate parameters. Although microstate analysis and inflammatory biomarkers have each been extensively investigated in psychiatric disorders, studies evaluating these two biomarkers together, particularly with the inclusion of healthy control participants, in the older age population remain limited. In this regard, the present study aims to evaluate the effects of ECT on older age patients using objective neurophysiological indicators, contribute to the understanding of the pathophysiology of depression at the level of brain networks, and provide a scientific basis for the development of personalised treatment approaches in the future.

EPI-MINN: Targeting Cognition and Motivation - National

The purpose of this study is to perform a practice-based research project designed to assess whether cognition and motivated behavior in early psychosis can be addressed as key treatment goals within real-world settings by using a 12-week mobile intervention program. We will recruit participants who are receiving care for early psychosis from clinics across the United States. We will compare outcomes from participants who receive treatment at coordinated specialty care (CSC) early psychosis clinics to those that receive standard community care. A qualifying CSC program will provide comprehensive clinical services such as psychotherapy, medication management, psychoeducation, and work or education support. This study will be conducted remotely, and participants can participate at home with their own electronic devices. The aim of this study is to investigate a well-defined 12-week mobile intervention program specifically designed to target cognitive functioning and motivated behavior for individuals with early psychosis. Participants will complete a screening interview which will include diagnosis and symptom ratings, neurocognitive assessment, and self-reports of symptoms, behavior, and functioning. Then participants will be randomized to receive the 12-week mobile intervention, or an active control of treatment as usual. The investigators will test for differences in the clinical trajectories after training, and at two follow up appointments at 6 and 12 months post-training.
