Diagnosis / Prognosis - Medibio Depression Diagnostic Aid
Diagnosis / Prognosis - Mini International Neuropsychiatric Interview
Diagnosis / Prognosis - Hamilton Rating Scale for Depression - 17 Item

Depressed - Subjects currently experiencing a moderate-to-severe major depressive episode are clinically evaluated over approximately 2-week period. 24-hour ECG data recordings are collected during each of the two weeks. Subjects may continue on current treatment regimen.

Control - Subjects not currently experiencing a major depressive episode are clinically evaluated over approximately 2-week period. 24-hour ECG data recordings are collected during each of the two weeks. Subjects may continue on current treatment regimen.


Diagnosis / Prognosis: Medibio Depression Diagnostic Aid
The Medibio DDA processes the heart rate and actigraphy data from the third-party devices, characterizes these data in comparison to the benchmark patterns of persons currently experiencing a depressive episode.

Diagnosis / Prognosis: Mini International Neuropsychiatric Interview
The Mini International Neuropsychiatric Interview (M.I.N.I.) is a structured diagnostic interview that was developed as a simple tool to assist clinicians to conduct psychiatric diagnoses according to the DSM-IV and International Statistical Classification of Diseases and Related Health Problems tenth revision (ICD-10) criteria.

Diagnosis / Prognosis: Hamilton Rating Scale for Depression - 17 Item
The clinician-administered Hamilton Depression Rating Scale (also known as the HAM-D) is the most widely used depression assessment scale . The original version contains 17 items (HDRS17) pertaining to symptoms of depression experienced over the past week. There are numerous versions with varying lengths that include the HDRS21, HDRS24, and HDRS29. This study will utilize the HDRS17 (HAMD-17) version.
