[The influence of age on vestibular function].

Regular changes in vestibular responsitivity as a function of age are demonstrated with the maximum speed of the slow phase of caloric nystagmus. The clinical implication of this is that, when doing caloric tests, one should not switch for no reason from a once accepted temperature sequence, otherwise comparison with other tests becomes impossible. It rotation tests the best reactions are found in young people. The amplitude is a good parameter to detect age-factors in rotatory nystagmus.
