Matutinal vertigo, characterized by vertiginous attacks occurring in the morning, has been noted in a significant percentage of patients with vestibular disorders and is considered to be precipitated by the patient's movements preparatory to arising from bed. Chronobiological studies of the variations of positional nystagmus in 10 patients with acute vertigo revealed rhythms of circadian periodicities in eight. The acrophases (i.e. computed peak hour), of nearly 40% of the circadian rhythms were found between 02.00 and 07.00 hours. Chronobiological characteristics of the vestibular system are postulated to play a part in the development of this clinical phenomenon.
