Description: This study will include clinical, cognitive, and neuroimaging data from older depressed subjects. The final dataset will include clinical information about subject psychiatric diagnoses, psychiatric and medical history, cognitive data, and response to L-dopa . The investigators will share data via the National Database for Clinical Trials related to Mental Illness (NDCT). NDCT provides a secure platform for data-sharing allowing for communication of research data, tools, and supporting documents. As required by NDCT, the investigators will obtain a Global Unique Identifier (GUID) for each participant. The investigators will additionally follow NDCT requirements to certify and review data, as well as timeline requirements for data submission and data sharing. Sharing of neuroimaging data will also be facilitated by an XNAT system (xnat.org). XNAT is an open-source informatics software platform that assists in the management and archiving of imaging data.
