Insomnia is a sleep disorder characterized by persistent difficulty falling asleep, staying asleep, or achieving restorative sleep — despite having adequate opportunity for sleep. When insomnia is chronic and causes significant daytime impairment, it meets the clinical threshold for a diagnosable condition rather than a normal variation in sleep patterns.
Veterans experience insomnia at substantially higher rates than the general population. Studies consistently find that sleep disturbance is one of the most prevalent and functionally impactful complaints among veterans seeking mental health care.
How Insomnia Affects Functioning
Poor sleep is not simply an inconvenience. Chronic insomnia degrades cognitive performance, emotional regulation, physical health, and occupational functioning in measurable ways. Veterans living with chronic insomnia often report difficulty concentrating at work, increased irritability and interpersonal conflict, impaired reaction time, reduced motivation, and worsening of other mental and physical health conditions.
The Relationship Between Insomnia and Other Service-Connected Conditions
Insomnia is deeply intertwined with PTSD, depression, anxiety, TBI, and chronic pain — all conditions commonly found in the veteran population. Nightmares related to trauma, hyperarousal that prevents relaxation, pain that interrupts sleep, and the cognitive rumination associated with depression and anxiety all contribute to and sustain insomnia.
Importantly, insomnia can be claimed as a condition secondary to PTSD or another service-connected diagnosis, or it may be claimed as a primary condition directly related to military service.
VA Service Connection for Insomnia
The VA recognizes insomnia as a ratable condition. It may be rated under the diagnostic code for sleep apnea if a sleep study confirms that diagnosis, or it may be rated as a mental disorder if it is directly related to a psychiatric condition. In some cases, veterans are entitled to a separate rating for insomnia in addition to their PTSD or depression rating when the sleep disturbance causes distinct functional impairment beyond what those ratings already capture.
A comprehensive sleep and psychological evaluation can help clarify the diagnosis, document the functional impact, and support the most appropriate rating pathway for your specific situation.
Note: if you have been diagnosed with sleep apnea, it is much less likely that you will be diagnosed with what psychologists consider a “primary insomnia.” A primary insomnia is a sleep disorder that has its origins in a mental health condition, rather than being an outcome of a medical issue.
