This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands.
Early vestibular evoked potentials were recorded with an extratympanic electrode. The recording principle was adding responses phase locked to a recording frequency. The recording frequency was empirically determined to match harmonically an individual response frequency and thus allowing averaging. This new technique was evaluated in benign paroxysmal positioning vertigo. Normal data were obtained from 12 […]
In a randomized, double-blind clinical study, we evaluated the efficacy and tolerability of the fixed combination of cinnarizine, 20 mg, and dimenhydrinate, 40 mg (Arlevert [ARL]) in comparison to betahistine dimesylate (12 mg) in 82 patients suffering from Ménière’s disease for at least 3 months and showing the characteristic triad of symptoms (paroxysmal vertigo attacks, […]
33 patients (9 male and 24 female) aged 28-59 (average 43,2) with multiple sclerosis were tested on the base of electro/videonystagmography. The duration of the disease was from half a year to 26 years. The aim of this study was to estimate the frequency of the central and peripheral vestibular disturbances in multiple sclerosis due […]
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
The possible relationship between inner ear and vasopressin (AVP, ADH) has been hypothesized since twenty years ago About ten years ago, in anaesthetized guinea pigs, we demonstrated that changes in the inner ear pressure modify plasma AVP (pAVP) level and AVP secretion with consequent changes in urine flow rate and osmolality : our experiment was […]
Whiplash injuries induce abnormalities in head-trunk control due both direct impact on the neck and indirect involvement of the central vestibular system. It is usually difficult to document specific abnormalities due to whiplash injuries. We stated that examinations aimed to document head-trunk coordination involvement could be useful in the functional assessment of vestibular disorders in […]
The variety of suggested treatments of nystagmus probably reflect its multiple pathogenetic mechanisms. Basic studies have shown that several neurotransmitters are involved in the ocular motor control, including gamma-aminobutyrric acid (GABA), acetylcholine and glycine. Recently, Stahl et al. (1995 ) investigated the effects of gabapentine on acquired pendular nystagmus in two patients with multiple sclerosis. […]
THE FUNCTION OF THE VESTIBULO-OCULAR REFLEX (VOR) IS TO STABILIZE VISUAL IMAGES ON THE RETINA DURING HEAD MOVEMENTS, THEREBY ENSURING MAXIMAL VISUAL ACUITY. IT IS POSSIBLE TO OBTAIN RELIABLE AND QUANTITATIVE INFORMATION ON VESTIBULAR FUNCTION USING A MOTORISED CHAIR, WITH THE SUBJECT’S HEAD AND BODY FIXED. SUCH TESTING OF THE VOR HAS ENTAILED LOW-FREQUENCY ROTATION […]
