Characterizing Inflammatory Profiles and Suicidal Behavior in Adolescents
Despite increasing suicide rates in adolescents, there remains a paucity of approaches to use to prevent re-attempts. Any hope for breaking the code to prevent youth suicide lies in understanding biological factors that play a role. Evidence suggests that inflammation and immune system dysfunction may be linked to suicide. The investigators will develop immune profiles for adolescents with suicidal behavior and those at risk in order to develop tools that can be implemented for prevention efforts. This study involves blood draws, answering questions, and completing questionnaires - no treatment or intervention is provided as part of this study. Participants will be screened to see if they qualify for this study using questionnaires. Participants will be teens (ages 12-18 years) with recent suicidal behavior, teens at-risk for developing depression, and healthy control teens. Participants complete all study-related tasks four times over a period of 12 months. Electronic surveys will be sent to participants to complete monthly. Both the adolescent and if applicable, their parent (or legally authorized representatives, LARs), will answer questions regarding depression, anxiety, and suicidal thoughts/behaviors.

Inclusion Criteria Study participants must: 1. Be adolescents (aged 12-18 years); 2. Have the ability to speak, read, and understand English. The parent(s) or legal guardians of minors must also speak, read and understand English; 3. Be willing to provide consent/assent. Consent will be provided by parents/LAR/guardian for youth under age 18 or by young adult participant, aged 18. Youth, aged 8-17, must be willing to provide assent; 4. Have the ability to complete clinical evaluations and self-report measures; 5. Meet criteria for one of these three groups: 1. Adolescent with suicidal behaviors, defined as having a recent (within 3 months) suicide attempt or suicidal ideation warranting urgent evaluation; 2. Adolescents at risk for mood disorders, defined by either personal history of anxiety disorder or substance use disorder or a history of trauma, or a first degree relative with a history of a mood disorder or suicidal history; 3.

Resilience in Adolescent Development (RAD)
The RAD study is a longitudinal study to prospectively characterize the biological mechanisms of resilience in adolescents and young adults at risk for developing depression. The study will capture biomarkers from the domains of socio-demographic and clinical data, cognitive and psychological assessments, fluid-based biomarkers, neuroimaging and EEG. Such biomarkers will compose a human biosignature of resilience and identify risk factors for depression, contributing to effective treatment selection or may represent moderators of response or non-response to treatments in subjects with depression. A cohort of 1,500 participants, age 10-24 will be recruited over a 5 year period. Participants will be followed for 10 years following an initial baseline visit. Study visits are conducted 4 times per year.
10 Years to 24 Years old
• Adolescents and young adults aged 10-24, male and female of all races and ethnicity.
• Participants must be English-speaking (because several study assessments are only available in the English language), however the parent(s) or legal guardian may either speak English or Spanish as the consenting process can be conducted bilingually.
• Adults age 18 and older must be able to provide written informed consent; for youth younger than age 18, a parent or legal guardian must provide written informed consent, and the child or teen must provide written informed assent.
• Ability to complete clinical evaluations and neuropsychological testing.
• Individuals who are unable to provide informed consent.
• Participants who are non-English speaking.
• Individuals with any of the following psychotic features: MDD with psychotic features, schizophrenia, schizoaffective disorder, or other Axis I psychotic disorder.
• Individuals with a depression diagnosis or a history of depression diagnosis at the initial visit (participants who develop depression during the longitudinal follow-up will continue in the study).
• A PHQ-9 score of 10 or greater.
• Individuals who are unable to provide a permanent home address and contact information.
• Individuals with any condition for which, in the opinion of the investigator, study participation would not be in their best interest (e.g., compromise their well-being) or that could prevent, limit, or confound the protocol-specified assessments.

Youth Depression and Suicide Research Network (YDSRN)
The objective of this study is to build the Texas Youth Depression and Suicide Research Network to support the development of a Network Participant Registry and characterization of systems and interventions to examine statewide population health outcomes. All 12-13 sites represented in the Texas Child Mental Health Care Consortium (https://www.utsystem.edu/pophealth/tcmhcc/) have been invited to participate in the Texas Youth Depression and Suicide Research Network as "Nodes." 12 Nodes have been selected for this project. Each Node has obtained support of senior institutional leadership including the department chair. Leadership from each Node provided input and edits in the study design process by committee, with a focus on the inclusion of the "end user" in design decisions. Nodes will work closely with the Network Hub leadership to recruit, monitor, and retain participants. This will require active engagement and sustained relationships with clinics within the academic medical center as well as clinics in the community (i.e., psychiatry, psychology, counselling).
8 Years to 20 Years old
Inclusion Criteria:1. Be 8 to 20 years of age; 2. Have a positive screen for depression (e.g., based on PHQ-2 (score ≥3) and/or PHQ-A of 10 or greater, OR positive for suicidal ideation or behavior (e.g., based on CHRT-SR or PHQ-A item 9); OR be in treatment for depression; 3. Be willing to provide consent/assent (parents/LAR/guardian or young adult participant, aged 18-20, must be willing to provide consent; youth, aged 8-17, must be willing to provide assent); 4. Be able to speak English or Spanish sufficiently to understand the study procedures and provide written informed consent to participate in the study; 5. Be willing to dedicate appropriate time to complete scheduled study assessments and measures (both parent/LAR/guardian and youth). 6. Be able to provide a reliable means of contact.
Exclusion Criteria:1. Have an acute medical or psychological condition(s) that that would, in the judgment of the study medical clinician, make participation difficult or unsafe; 2. Have an acute medical or psychological condition(s) that would result in an inability to accurately complete study requirements (e.g., neurological conditions or significant neurodevelopmental concerns); 3. Have active psychotic symptoms resulting in altered mental status and inability to provide assent or requiring immediate attention and/or higher level of intervention; 4. Have a parent/LAR/guardian who is deemed cognitively unable to provide consent (if youth participant, aged 8-17).

Aging and Disease Course: Contributions to Lifespan Neurobiology of Schizophrenia
The 2020 NIMH Strategic Plan for Research calls for investigations targeting neurobiology of mental illness across the lifespan. Growing evidence suggests that lifespan neurobiology of schizophrenia (SZ) incorporates two distinct dimensions: aging and disease course. However, their clinical correlates, associated biomarker trajectories, and implications for treatment are unknown. This study will investigate differential aspects of SZ neurobiology captured by aging and disease course, in order to develop specific biomarkers which may offer actionable targets for SZ stage-dependent intervention. The study is predicated on a novel mechanistic Model of SZ Trajectories across the Adult Lifespan, positing distinct biological fingerprints within the anterior limbic system for aging and disease course in SZ: (1) alterations in the circuit's function and structure that occur earlier in the lifespan and are larger in magnitude than the alterations expected with normal aging (accelerated aging dimension); and (2) regionally-specific anterior limbic "hyperactivity" in early SZ, with a subsequent transformation into "hypoactivity" in advanced SZ (disease course dimension). In a sample of SZ and matched healthy controls (n=168, 84/group) aged 18-75 years the investigators will ascertain a broad panel of biomarkers [via multimodal brain imaging: optimized 1H-MRS, high-resolution task-based fMRI, perfusion (Vascular Space Occupancy) and structural MRI], along with comprehensive cognitive and clinical assessments. All measures will be acquired at baseline and repeated at 2-year longitudinal follow-up. Using cutting-edge computational approaches, the study will examine (i) effects of aging and SZ course on anterior limbic system biomarkers; (ii) lifespan trajectories for different biomarkers; (iii) patterns of limbic system biomarkers in age- and SZ course-based subgroups (e.g., Younger vs. Older, Early-Course vs. Advanced SZ), as well as in data-driven subgroups (e.g., those with vs. without accelerated aging profiles); and (iv) associations between biomarkers and cognitive and clinical outcomes. This research will advance the field by providing novel biomarkers that capture unique neurobiological contributions of aging and disease course in SZ, and will motivate future studies on SZ mechanisms across the lifespan and development of precision treatments.
