BPPV vs. Chronic Dizziness: What's the Difference and How Is Each Treated?

Two very different problems. Two very different solutions. Here's how to tell them apart.

Not all dizziness is the same — and treating it as though it is leads to months of frustration, ineffective interventions, and a lot of people in the Conejo Valley and surrounding communities being told "we can't find anything wrong."

At MBODY Physical Therapy and Wellness in Westlake Village, vestibular rehab is a clinical specialty, not a side service. Part of what makes our approach effective is starting with an accurate diagnosis. The two most common vestibular conditions we treat — BPPV and vestibular hypofunction — are frequently confused, respond to completely different treatments, and require a trained clinician to distinguish.

What Is BPPV?

Benign Paroxysmal Positional Vertigo is exactly what the name describes: benign (not dangerous), paroxysmal (comes in sudden bursts), positional (triggered by head position changes), and vertigo (a spinning sensation). BPPV happens when calcium carbonate crystals — otoconia — that normally sit in one part of the inner ear become dislodged and migrate into the semicircular canals, where they don't belong.

When your head moves, these crystals move with it and create a false signal of rotation. The result: brief but intense spinning, typically lasting seconds to a minute, triggered by rolling over in bed, looking up, bending down, or tipping your head.

BPPV is the most common cause of vertigo. It's also one of the most treatable conditions in all of medicine when diagnosed correctly — often resolving in 1–3 visits with the appropriate repositioning maneuver (the Epley, Semont, or others depending on which canal is involved).

What Is Vestibular Hypofunction?

Vestibular hypofunction is a reduction in the function of one or both vestibular organs — the parts of the inner ear that signal head movement to the brain. It most commonly follows a vestibular neuritis (viral inflammation of the vestibular nerve), labyrinthitis, or sometimes appears after head injury, illness, or certain medications.

The experience is different from BPPV. Instead of brief spinning episodes, people with vestibular hypofunction describe:

• Persistent unsteadiness or "rocking" sensation

• Visual disturbance with head movement — difficulty reading signs while moving, blurry vision when turning the head

• Fatigue and mental fog, particularly in busy visual environments

• Difficulty in low-light environments where vision can't compensate

• Anxiety in crowds or open spaces — because the brain is working overtime to stay oriented

Treatment for vestibular hypofunction is not a repositioning maneuver. It's a structured program of vestibular adaptation and substitution exercises — training the brain to recalibrate its balance processing using visual and proprioceptive input to compensate for the reduced inner ear signal. This typically takes 6–10 weeks with a specialized vestibular PT.

Why Does the Distinction Matter So Much?

Because the treatments are not interchangeable. Performing a repositioning maneuver on someone who doesn't have BPPV does nothing — or can temporarily worsen symptoms. Prescribing vestibular adaptation exercises to someone who actually has unresolved BPPV is similarly ineffective. The wrong intervention doesn't just waste time; it can erode confidence in treatment altogether.

Accurate differential diagnosis requires specific clinical training: knowing how to perform and interpret the Dix-Hallpike test, the roll test, the head impulse test, and oculomotor assessments. This is what separates a vestibular specialist from a general PT who occasionally treats dizziness.

Other Conditions in the Mix

BPPV and vestibular hypofunction are the most common, but not the only possibilities. Vestibular migraine, Persistent Postural-Perceptual Dizziness (PPPD), Meniere's disease, and post-concussion vestibular dysfunction each have distinct presentations and treatment approaches. Part of what a thorough vestibular evaluation does is work through these possibilities systematically — and refer out when imaging or further medical workup is warranted.

The Bottom Line

If you've been dizzy for weeks or months — whether it's episodic spinning or constant unsteadiness — and haven't had a formal vestibular evaluation, that's the starting point. MBODY serves patients from across the Conejo Valley, including Westlake Village, Thousand Oaks, Calabasas, and Agoura Hills. No referral is required to book an evaluation.
