Researchers find that chronic dizziness may be caused by psychiatric and neurologic illnesses

Approximately 9 million to 15 million people in the U.S. suffer from recurrent bouts of dizziness and 3 million experience symptoms of dizziness nearly every day. According to a paper that appears in the February issue of Archives of Otolaryngology–Head & Neck Surgery, researchers at the University of Pennsylvania School of Medicine found that chronic subjective dizziness (CSD) may have several common causes, including anxiety disorders, migraine, mild traumatic brain injuries, and neurally mediated dysautonomias – disorders in the autonomic nervous system, which controls involuntary actions.
