Benign paroxysmal vertigo in children is characterized by sudden attacks of vertigo lasting seconds or minutes. During the attack, the child has nystagmus and is unable to stand without support. Initially, the attacks are frequent, later slowly disappearing. Nineteen children who were diagnosed in 1975-1981 participated in a follow-up study. Sixteen of them were examined with audiometry and electronystagmography. Age at onset was from 5 months to 8 years, and the symptoms disappeared after 3 months to 8 years. The follow-up was performed 13 to 20 years after diagnosis. Twenty-one percent developed migraine which is somewhat more than in a normal population of this age. Thirty-nine percent had a family history of migraine which is a figure considerably lower than in a migraine population. None still had vertigo or a balance disorder. Our conclusion is that benign paroxysmal vertigo has a favorable outcome, and it is not a general precursor of migraine.
