Nei 17-06 ((better)) ⟶ [ FAST ]

Using OCT angiography, the NEI 17-06 team discovered that suicidal participants had lower parafoveal capillary density and a larger foveal avascular zone (FAZ). This indicates chronic ischemia (reduced blood flow) in retinal tissues. Because the retina and brain share similar vascular autoregulation, this finding supports the “vascular depression” hypothesis and suggests that microvascular injury may be a mechanism linking severe depression to suicide.

While many clinical trials focus on drug efficacy or behavioral outcomes, NEI 17-06 stands apart. It asks a fundamentally different question: Can we predict and understand suicidal risk by looking at the retina and its connection to the brain? This article provides a comprehensive breakdown of NEI 17-06, its methodology, its implications for psychiatry, and why it matters for patients and clinicians alike. nei 17-06

The advantage of NEI 17-06 is that OCT devices are already present in thousands of clinics (optometry, ophthalmology, neurology). Thus, translation, if validated, would be faster than for any other biomarker. Using OCT angiography, the NEI 17-06 team discovered

In the high-stakes world of commercial nuclear power, safety is not merely a procedure; it is a culture. While rigorous engineering and redundant safety systems form the physical backbone of a nuclear facility, the human element remains the most variable factor. To manage this, the nuclear industry relies on a framework of guidelines known as Nuclear Enterprise Institute (NEI) documents. Among these, stands out as a pivotal document that redefined how the industry approaches the interaction between human behavior, leadership, and safety. While many clinical trials focus on drug efficacy

Although internal protocol numbers like NEI 17-06 are used within the NIH, the study is publicly registered. NEI 17-06 refers to Protocol 17-EN-0066, approved by the NIH Institutional Review Board (IRB). The study began enrolling participants in 2017 and has since produced a series of peer-reviewed findings.
