This was tested in people. That is the most reliable kind of research we share.
This was a small report on 6 patients who were already treated, not a trial of a new treatment.
The short version
In 6 people, dizziness that seemed to be a common inner ear problem turned out to start in the brain, and a brain MRI found the real cause.
What was studied. Doctors reported on 6 patients whose dizziness came on when they changed position. There were 3 men and 3 women, aged 18 to 85. All had been sent to physiotherapy for a presumed inner ear problem called BPPV.
What they found. A careful exam showed warning signs in these patients, so they were sent for a brain scan. Brain MRI found the true cause in all of the cases. The causes included tumors in the cerebellum, a stroke in the midbrain, migraine with changes seen on the scan, a blood vessel pressing on a nerve, and shrinking of the cerebellum. In every case the scan corrected the first diagnosis and stopped head-positioning treatments that were not right for them.
What this means, and what it doesn't
What it could mean: Dizziness that starts when you move your head usually comes from the inner ear. Sometimes it does not. If certain warning signs show up in the exam, a brain MRI can find a cause inside the brain. Some of the causes found here were brain tumors. Finding the right cause can lead to the right care sooner.
What it doesn't mean: This does not mean that dizziness usually means a brain tumor. Most positional dizziness still comes from the inner ear. This was a small report on 6 patients that doctors had already seen. It was not a trial, and it did not test any new treatment. It does not prove that scanning everyone helps, and it is not a cure for anything. It is mainly a reminder for doctors to look closer when warning signs are there.
