Balance and Dizziness After a Concussion: Why Vestibular Symptoms Deserve Their Own Evaluation

Balance problems and dizziness are among the most common symptoms after a concussion or mild traumatic brain injury (mTBI), but they're frequently overshadowed by headache and cognitive complaints in how patients describe their own injury. A patient might mention feeling "off" or "not quite steady" almost in passing, long after they've already brought up headache, fatigue, or trouble concentrating. Our physician team treats vestibular symptoms, dizziness, imbalance, motion sensitivity, as a distinct part of the concussion picture that warrants its own evaluation, not a footnote to the rest of the workup.

How Common These Symptoms Actually Are

According to PubMed, a retrospective study of 84 military service members with chronic mTBI found that 71.4% reported at least one vestibular symptom: dizziness in 40.5%, imbalance in 23.8%, visual motion hypersensitivity in 13.1%, and motion sickness in 17.9% (Hu et al., 2026, Military Medicine, DOI). A separate clinical review notes that vestibular symptoms are common after sports-related concussion specifically, and that they carry real prognostic weight, predicting slower recovery and delayed return to play when they aren't identified and addressed early (Israel & Steenerson, 2026, Neurologic Clinics, DOI).

One Specific, Treatable Cause: Post-Traumatic BPPV

Not all post-injury dizziness has the same source, and one cause in particular is both common and directly treatable. According to PubMed, a prospective cohort study of 156 patients presenting to an emergency department with mild TBI found that 20 of them, 12.8% (95% CI 7.7–17.9%), had trauma-related benign paroxysmal positional vertigo (t-BPPV), diagnosed using standard Dix-Hallpike and supine roll testing. Female sex (odds ratio 4.66) and high-energy trauma (odds ratio 3.80) were both significant risk factors (Dao et al., 2026, Journal of International Advanced Otology, DOI). A separate review describes how post-traumatic BPPV differs meaningfully from the idiopathic form most people associate with the condition, more often involving multiple or horizontal canals and more frequently requiring repeated canalith repositioning treatment, and proposes a structured pathway for recognizing and managing it early (Kong & Seo, 2026, Frontiers in Neurology, DOI).

It's Rarely Just One System

Dizziness after a concussion doesn't usually trace back to a single, isolated cause. A recent review describes post-concussive vestibular dysfunction as emerging from complex interactions between the peripheral vestibular system, the central nervous system, and the cervical spine, often worsened by impaired sensory reweighting, the brain's ability to correctly combine visual, vestibular, and body-position signals (Shin et al., 2026, Korean Journal of Neurotrauma, DOI). The visual system is frequently part of that picture too: in the military cohort referenced above, 54.8% of participants had a measurable vertical vergence imbalance between the eyes, and a higher vestibular symptom count was significantly correlated with the degree of that imbalance (Hu et al., 2026, Military Medicine, DOI). That overlap is part of why a thorough evaluation looks at vestibular, visual, and cervical function together rather than assuming a single explanation.

Vestibular Rehabilitation Has Randomized Trial Evidence Behind It

Unlike some post-concussion symptoms, vestibular dysfunction has a treatment approach with real clinical trial support. According to PubMed, a randomized clinical trial of 120 adults with mTBI-related vestibular impairment assigned participants to home exercise programs at different intensities and frequencies over four weeks. Across all participants, the mean improvement on the Dizziness Handicap Inventory from baseline to four weeks was 16 points (95% CI 13–19, P < .0001), and most secondary outcome measures also improved significantly, with the trial's authors concluding that the exercise dose can be individualized to a patient's goals and symptom burden rather than following one fixed protocol (Sparto et al., 2026, Journal of Neurologic Physical Therapy, DOI). A companion review describes the broader shift toward mechanism-based, individualized vestibular rehabilitation therapy, distinguishing conditions like cervicogenic dizziness and persistent postural-perceptual dizziness from structural inner-ear problems, since each points toward a different treatment path (Shin et al., 2026, Korean Journal of Neurotrauma, DOI).

When It's Worth Raising With a Physician

Dizziness or unsteadiness that shows up after a head injury, whether it's a brief spinning sensation with certain head movements, a general sense of imbalance, or discomfort in busy visual environments like grocery stores or traffic, is worth describing to a physician directly rather than waiting to see if it resolves on its own. Because vestibular symptoms overlap with headache, visual strain, and neck-related pain, our physician team evaluates them as part of the full post-concussion picture rather than as an isolated complaint.

Getting Evaluated

If balance problems or dizziness have followed a head injury and haven't settled the way you'd expect, it's worth bringing up directly at your next visit. Learn more about concussion care at NeuroLUX, or schedule an evaluation with the physician team.
