Can a Head Injury Cause Vertigo?
Understanding Post-Concussion Vertigo and BPPV: Causes, Symptoms, and Treatment
Experiencing a concussion can be a life-altering event, often accompanied by a range of symptoms that extend beyond the initial injury. One common and particularly disruptive symptom is vertigo, a sensation of spinning or dizziness. Post-concussion vertigo can significantly impact daily life, making it essential to understand its causes, symptoms, and available treatments. One specific type of vertigo frequently associated with concussions is Benign Paroxysmal Positional Vertigo (BPPV). Let’s delve deeper into this condition and explore effective strategies for managing it.
What is Post-Concussion Vertigo?
Vertigo is a condition where you feel like you or your surroundings are moving or spinning, even when everything is stationary. After a concussion, vertigo can occur due to disruptions in the brain’s ability to process spatial orientation and balance. This disruption can result from damage to the inner ear or the brain’s vestibular system, which is responsible for maintaining balance and spatial awareness.
Understanding BPPV
Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common types of vertigo and is frequently seen in individuals who have suffered a concussion. BPPV occurs when tiny calcium carbonate crystals (otoconia) in the inner ear become dislodged and move into the semicircular canals. These canals are fluid-filled structures that help detect head movement. When the crystals interfere with the fluid movement, it sends incorrect signals to the brain, causing the sensation of vertigo.
Symptoms of Post-Concussion BPPV
The symptoms of BPPV can be quite distressing and may include:
Dizziness: A sensation of spinning or moving.
Nausea: Feeling queasy or sick to your stomach.
Balance Problems: Difficulty maintaining balance, leading to unsteadiness or falls.
Nystagmus: Rapid, uncontrolled eye movements.
These symptoms are often triggered by specific head movements, such as rolling over in bed, looking up or down, or quickly turning the head.

Diagnosing BPPV
Diagnosing BPPV involves a thorough medical history and physical examination. A key diagnostic tool is the Dix-Hallpike test, where the patient is quickly moved from a sitting to a lying position with their head turned to one side. The healthcare provider observes for signs of nystagmus and asks about dizziness to determine if BPPV is present. Click here for video
Treating Post-Concussion BPPV
The good news is that BPPV can often be effectively treated with specific maneuvers designed to move the dislodged crystals out of the semicircular canals and back to their proper location. One of the most common treatments is the Epley maneuver.
The Epley Maneuver
The Epley maneuver involves a series of head and body movements performed by a healthcare provider or at home under professional guidance. Here’s a simplified version of how it’s done:
Start Sitting: Begin by sitting upright on a bed with your legs extended.
Head Turned: Turn your head 45 degrees to the affected side. (Side with worse symptoms)
Lie Back Quickly: Lie back quickly with your head hanging slightly off the edge of the bed and wait for 30 seconds.
Head Rotation: Turn your head 90 degrees to the opposite side and wait for another 30 seconds.
Body Turn: Turn your entire body to the same side your head is facing, wait 30 seconds.
Sit Up Slowly: Slowly sit up and remain in the sitting position for a few minutes.
These movements help guide the crystals back to their original location in the utricle, relieving the symptoms of vertigo.
Comprehensive Recovery
While maneuvers like the Epley maneuver can provide immediate relief, it’s crucial to address the underlying concussion to achieve a full recovery.
