“…Specific (Hallpike-Dix positioning maneuver with or without Frenzel lenses [ICS Medical, USA]) (7,15) and nonspecific (Fukuda stepping) tests may help clarify a vestibular involvement without the use of special equipment (7,12,47). Peabody and OseretskyBruninks tests are also useful in clarifying the diagnosis.…”

“…First described by Barany in 1920 (14), BPPV is characterized by recurring acute attacks of vertigo of short duration, usually provoked by changes in head position. BPPV is known by a variety of names, such as 'positional nystagmus of the benign paroxysmal type' (15) and 'benign recurrent vertigo' (9). These names refer to the importance of sudden changes in head-onbody positioning that provoke episodic and reversible symptoms (16).…”

The aim of this study was to analyze the eVect of acute vestibular deWcit on the cerebral cortex and its correlation with clinical signs and symptoms. Eight righthanded patients aVected by vestibular neuritis, a purely peripheral vestibular lesion, underwent two brain single photon emission computed tomography (SPECT) in 1 month. The Wrst SPECT analysis revealed reduced blood Xow in the temporal frontal area of the right hemisphere in seven of eight patients, independent of the right/left location of the lesion. The alteration was present always in the right, non-dominant hemisphere and was reversible in some patients 1 month after the onset, together with attenuation of signs and symptoms. It may be hypothesized that the transient reduction of cortical blood Xow and subsequently of cortical activity in the non-dominant hemisphere, also the expression of cerebral plasticity, may serve as a defense mechanism aimed to attenuate the vertigo symptom.

“…The vestibular system integrates the information sent by the peripheral receptors -the eyes, the propioceptors and the labyrinths. Such information is directed towards the vestibular nuclei and from there it is sent to and processed by the central nervous system 3 . The proper functioning of this system depends on the perfect integration of all the information that come from peripheral receptors.…”

Introducti on: Impaired glucose metabolism is characterized by conditions of hypo and hyperglycemia. Aim: The objective of the present study was to asses whether or not there is a relationship between impaired glucose metabolism and dizziness. In the clinical laboratory settings, patients were examined using vectoelectronystagmography in association with glycemic levels. Methods: 33 patients were divided in 3 groups: diabetics; patients with dizziness and a control group. Results:65% of the patients with dizziness showed impaired glucose metabolism. 40% of the patients with dizziness had alterations in their vectoelectronystagmography results. Conclusion: Dizziness is a good indicator of glucose metabolism alterations and these may be a good indicator of alterations in vectoelectronystagmography responses. The study of glycemic levels after glucose overexposure is a good prognosis factor to evaluate dizziness and shows the same results as insulin level studies after glucose overexposure.
