New Clues to Chronic Dizziness
Psychiatric, Neurological Problems May Cause Unexplained Dizziness, Study Shows
"The idea that dizziness is either medical or psychiatric is potentially
problematic because so often it is both," Staab says. "And typically
when it is both, the illness began as a medical condition."
For instance, he says, a chronically dizzy patient may tell his doctor he is
afraid to drive because of dizziness, and the doctor labels it as a psychiatric
But the patient may have forgotten to mention that an inner ear infection
initially made him dizzy and made him anxious about driving.
Patients with chronic dizziness need to be screened for headaches, brain
injuries, and other problems in addition to simply anxiety, Staab says.
Another Expert Weighs In
The new study builds on previous research, says Joseph Furman, MD, PhD, a
neurologist and professor of otolaryngology at the University of Pittsburgh and
a veteran researcher on the topic.
"If you take a close look at people who are dizzy without a diagnosis of
disease, the two main things you are going to come up with are anxiety and
migraine," he says, citing his own and others' research. "But it is
complicated. People with anxiety aren't immune to vestibular [inner ear]
That points to the wisdom, he says, of including both medical and
psychological assessments for chronic dizziness.
The study is published in the February issue of the Archives of
Otolaryngology Head and Neck Surgery.
