PTSD and tinnitus often travel together because the same blasts and combat events can cause both: a 2026 study found tinnitus in 67.5% of treatment-seeking post-9/11 veterans, and tinnitus, PTSD and brain injury together in 35.6%.
Tinnitus and PTSD are both among the most common service-connected disabilities in the US. In VA's benefits report for fiscal year 2025, tinnitus was the most prevalent service-connected disability among veterans receiving compensation, at 3,583,295, and PTSD was fifth, at 1,760,497. They overlap constantly, and for a long time each was treated as though the other were background.
How much they overlap
A 2026 study in the European Journal of Psychotraumatology examined treatment-seeking post-9/11 veterans and found:
- Tinnitus in 67.5% of the sample.
- Substantial comorbidity between tinnitus, PTSD and traumatic brain injury in 35.6% — more than a third had all three.
Two thirds is not a subgroup. In this population tinnitus is closer to the default condition than to a complication, which is the first reason it should not be treated as a side note during mental health care.
The overlap is not a coincidence either. The events that cause blast injury and combat trauma are the same events that cause acoustic trauma and head injury. One exposure, several consequences.
Which PTSD symptoms track with tinnitus
A 2022 study in Health Psychology, examining veterans with post-traumatic headaches, looked at this more precisely. Roughly half of the participants with tinnitus showed severe impairment from it.
Four clusters of PTSD symptoms were each significantly related to tinnitus-related distress — to how intrusive it was, how loud it was perceived to be, how aware of it people were, and how annoying they found it:
- Reexperiencing
- Avoidance
- Negative emotions and cognitions
- Hyperarousal
And the relationship held in the other direction: participants with severe tinnitus scored significantly higher on reexperiencing, negative mood and cognitions, hyperarousal, and total PTSD severity than those with mild or moderate tinnitus.
The idea worth taking to an appointment
Here is what makes that study more than another comorbidity paper. Its authors raise the possibility that heightened psychological symptoms seemingly related to PTSD may be a function of tinnitus-related distress.
Read the overlap in the symptom lists and the point becomes obvious:
- Hypervigilance to sound is a PTSD symptom. It is also what a brain does when it is monitoring a sound it cannot switch off.
- Sleep disturbance belongs to both.
- Irritability, difficulty concentrating and emotional numbing belong to both.
So a veteran reporting those symptoms may be describing trauma, or tinnitus distress, or — most often — an inseparable mixture. Their recommendation is direct: trauma therapists should assess for the presence of tinnitus, in order to conceptualise the patient's problems properly rather than attributing everything to the trauma by default.
That cuts the other way too. An audiologist treating tinnitus in a veteran who has never been asked about trauma is working with half the picture.
What tinnitus adds on its own
The 2026 study tested whether tinnitus contributes anything beyond what PTSD and brain injury already explain, which is the harder and more useful question.
It does, and the honest description is "a little". After accounting for PTSD severity and the number of traumatic brain injuries, tinnitus explained an additional 1.9–3% of the variance in pain (β = 0.184) and functional impairment (β = 0.145), both significant after adjusting for multiple testing.
For scale, PTSD itself predicted every outcome far more strongly (βs ranging in size from 0.226 to 0.657 across the outcomes, including 0.500 for pain and 0.657 for functional impairment). So tinnitus is not the main driver of how these veterans are doing. It is a real, independent, modest addition to the load — which is a more defensible claim than the one usually made for it, and it survived the adjustment that most such claims do not.
One finding pointed the other way and belongs here for completeness: tinnitus was stable over time but did not predict later pain or functional impairment. A cross-sectional association that does not reproduce longitudinally is weaker evidence of a causal role, and the study reports it plainly.
What to do
Say both things in the same appointment. The single most useful thing this research supports is that these are assessed together. If you are in trauma treatment and have tinnitus, say so. If you are in tinnitus treatment and have a trauma history, say that.
Do not accept "it's just the PTSD" without the tinnitus being asked about — and equally, do not assume difficulty sleeping and concentrating is all tinnitus when trauma is in the picture.
CBT is the practical common ground. It is first-line for tinnitus distress and well-evidenced in trauma. But the two protocols are different courses of treatment aimed at different targets, and being offered one does not mean you have had the other.
If you are a US veteran, tinnitus and VA disability covers the claims side, and tinnitus disability claims covers the evidence that secondary conditions — which is what PTSD is often rated as alongside tinnitus — carry most of the compensation.
If any of this is acute right now, the crisis resources at the end of this page are the right first step, tinnitus and suicidal thoughts covers how to raise it with a doctor and how family can help, and tinnitus and depression sets out what the suicidality research actually says, including why the number is published rather than softened.
