Dissecting Immunological and Autoimmune Mechanisms of Neuropsychiatric Diseases (DIAMOND)
The goal of this observational cohort study is to investigate the role of immune system in neuropsychiatric symptoms (NPS) and to identify immunological biomarkers that may improve the diagnosis, prognosis, and future treatment of immune-related neuropsychiatric disorders in individuals aged 16-100 years with suspected immune-mediated neuropsychiatric symptoms and matched control participants without neuropsychiatric symptoms.
The main questions it aims to answer are what immunological mechanisms are associated with neuropsychiatric symptoms across a range of neurological, psychiatric, autoimmune, infectious, and inflammatory conditions. Also, if immunological biomarkers can be identified that may support the diagnosis, prognosis, and future treatment of neuropsychiatric disorders in which the immune system may play a role.
Participants will provide a blood sample for immunological analysis and may optionally provide a cerebrospinal fluid (CSF) sample if a suitable previously collected sample is not available. Researchers may also analyse existing clinical and biological samples where available. Participants will provide demographic and clinical information, allow access to relevant medical record data, and may optionally provide additional blood samples, up to four times within one year, for further biomarker and immunological analyses.
