Chronic Insomnia Is Getting Service Members Separated Early — and the Data Proves It

For years, military disability attorneys have watched a troubling pattern: service members diagnosed with chronic insomnia disorder — a condition that is both real and debilitating — are being pushed out of uniform at rates that don't reflect the condition's treatability or the member's overall fitness for duty. Now, the data backs it up.

A study reported by U.S. Medicine found that service members with chronic insomnia disorder face a significantly increased risk of early separation from military service. Read the full report here.

This is not a minor finding. It has direct implications for every service member currently in — or approaching — the Medical Evaluation Board and Physical Evaluation Board process with a sleep disorder diagnosis.

The study's core finding is straightforward: chronic insomnia disorder is associated with a meaningfully elevated risk of early separation from military service. Service members with this diagnosis are leaving the military sooner than their peers — and in many cases, before they have had a full and fair opportunity to have their condition evaluated through the disability system.

That matters because early separation — particularly administrative separation — can strip a service member of the disability benefits they would otherwise be entitled to receive. A service member who is administratively separated for performance or conduct reasons, even when an underlying sleep disorder is the root cause of those performance issues, may lose access to medical retirement, VA disability compensation, and TRICARE coverage.

Chronic insomnia disorder occupies an awkward position in the military disability framework. It is a recognized medical diagnosis under DSM-5 criteria. But it is frequently undervalued, mischaracterized, or dismissed at the MEB stage — particularly when it appears as a secondary condition alongside a primary diagnosis.

Several dynamics make this condition especially risky for service members navigating the disability system:

1. It is often treated as a symptom rather than a standalone condition.

When chronic insomnia accompanies PTSD, TBI, or another primary diagnosis, Medical Evaluation Boards frequently fold it into the primary condition rather than evaluating it separately. This can result in a lower combined disability rating and, in some cases, a finding of fit for duty that would not have occurred if the insomnia had been properly evaluated on its own merits.

2. Performance consequences are real — and they can trigger administrative action.

Chronic insomnia impairs cognitive function, reaction time, emotional regulation, and physical performance. These are exactly the metrics the military uses to evaluate fitness for duty and career progression. A service member who is struggling with chronic insomnia may accumulate negative performance evaluations, fail physical fitness assessments, or exhibit behavioral changes that lead to administrative separation proceedings — all before the disability system has had a chance to evaluate whether the underlying condition is unfitting.

3. The administrative separation pipeline moves faster than the disability pipeline.

This is a structural problem in the military disability system that the insomnia research highlights in sharp relief. Administrative separation for performance or conduct can proceed quickly. The IDES/MEB/PEB process is slower. When a service member's insomnia is driving both the performance problems and the disability case simultaneously, there is a real risk that the administrative action concludes first — cutting off disability protections before they can attach.

To receive military disability retirement, a condition must be found unfitting — meaning it prevents the service member from performing the duties of their office, grade, rank, or rating. For chronic insomnia, this determination is highly fact-specific and often contested.

A service member with chronic insomnia that causes severe daytime impairment, cognitive dysfunction, and inability to maintain military readiness standards has a strong argument that the condition is unfitting. But that argument has to be made — clearly, with supporting medical evidence, and ideally with the assistance of an attorney who understands how Physical Evaluation Boards evaluate sleep disorders.

The MEB narrative summary (NARSUM) is the critical document. If the NARSUM understates the functional impact of the insomnia — or if it characterizes the condition as controlled or manageable when the service member's lived experience says otherwise — the PEB will likely follow that characterization. Rebutting a deficient NARSUM is one of the most important things a service member can do to protect their disability case.

Each branch handles the MEB and PEB process differently. If you are currently in the disability evaluation system, the branch-specific guides below explain how the process works for your service:

Chronic insomnia rarely exists in isolation. It is strongly associated with PTSD, major depressive disorder, generalized anxiety disorder, and traumatic brain injury — all conditions that are common in the military population and all conditions that carry their own disability rating implications.

When insomnia is comorbid with a mental health condition, the disability evaluation becomes more complex. The question is not just whether the insomnia is unfitting, but how it interacts with the primary mental health diagnosis, whether both conditions should be separately rated, and whether the combined picture supports a higher overall disability rating. Use our VA disability rating calculator to estimate how combined ratings — including a sleep disorder alongside a mental health condition — could affect your overall percentage and monthly compensation.

This is exactly the kind of analysis that requires legal and medical expertise. A service member navigating this alone — without an attorney and without an independent medical opinion — is at a significant disadvantage.

If you have been diagnosed with chronic insomnia disorder and you are facing either administrative separation or entry into the MEB/PEB process, there are several steps you should take immediately:

Get your medical records and review them carefully. Look at how your insomnia is documented. Is it characterized as a standalone diagnosis or as a symptom of something else? Is the functional impact — the daytime impairment, the cognitive effects, the impact on your military duties — clearly documented? Our MEB rebuttal guide walks through how to identify and challenge deficiencies in your NARSUM.

Do not accept a fit-for-duty finding without understanding your options. If the MEB finds you fit for duty despite a chronic insomnia diagnosis that is genuinely impairing your ability to serve, you have the right to rebut that finding and to request a formal PEB hearing.

Understand the difference between administrative separation and disability separation. If your command is pursuing administrative action at the same time your disability case is pending, the interaction between those two processes is legally significant. In some circumstances, the disability process should take priority. An attorney can help you understand your rights and protect your case.

Seek legal representation early. The earlier in the process you have an attorney, the more options you have. By the time a PEB has issued findings, some of the most important opportunities to shape the outcome have already passed.

The research on chronic insomnia and early military separation is a data point in a larger story about how the military disability system handles conditions that are real, serious, and often invisible. Sleep disorders don't show up on an X-ray. They don't produce the kind of objective findings that make a disability case straightforward. They require careful documentation, credible medical evidence, and an advocate who understands how to present that evidence to a Physical Evaluation Board.

Service members with chronic insomnia deserve the same fair evaluation as those with orthopedic injuries or other more visible conditions. The research confirms that they are not always getting it. That is a problem this firm takes seriously.
