1.6.2 Benign paroxysmal vertigo

A disorder characterized by recurrent brief attacks of vertigo, occurring without warning and resolving spontaneously, in otherwise healthy children.

Diagnostic criteria:
A. At least five attacks fulfilling criteria B and C
B. Vertigo1 occurring without warning, maximal at onset and resolving spontaneously after minutes to hours without loss of consciousness
C. At least one of the following associated symptoms or signs:

    1. nystagmus
    2. ataxia
    3. vomiting
    4. pallor
    5. fearfulness

D. Normal neurological examination and audiometric and vestibular functions between attacks
E. Not attributed to another disorder.

1. Young children with vertigo may not be able to describe vertiginous symptoms. Parental observation of episodic periods of unsteadiness may be interpreted as vertigo in young children.

Posterior fossa tumours, seizures and vestibular disorders must be excluded.

The relationship between 1.6.2 Benign paroxysmal vertigo and A1.6.6 Vestibular migraine (see Appendix) needs to be further examined.
