Symptoms such as vertigo and unsteady gait occur in various diseases and are among the relatively common chief complaints. Even at present, the mechanisms underlying these disorders are unclear. We report a significant correlation between a prolonged period of resolution of benign paroxysmal positional vertigo (BPPV) and histories of lifestyle-related illnesses. We consider the possibility of c...

Retinomotor movements are morphological changes in the outer retina in response to changing light conditions. They can be separated into two components: Migration of pigment granules within the microvilli of the retinal pigment epithelium (RPE) and positional changes in photoreceptor cells. These positional changes optimize exposure of the cone and rod photoreceptors to light. The aim of this s...

The vestibular nervous system senses linear and angular acceleration upon the head during postural change generates nerve activity changes. autonomic regulates involuntary physiologic processes throughout peripheral central systems. systems interplay several brain regions to maintain homeostasis changes, called vestibulo-autonomic reflex. In this review, we first contemplated anatomic propertie...

It has become clear that foods crushing is performed in the circumscribed region between functional cusps, that is, at "the main occluding area". However, it is not established to evaluate this area objectively. The purpose of this study was to establish the positional evaluation of the main occluding area quantitatively and evaluate the positional change depending on the age with this method. ...

Migraine and vertigo are common disorders, affecting about 14% and 10%, respectively, of the general population. If migraine and vertigo were unrelated, the expected comorbidity would be 1%, whereas recent epidemiological studies indicate that 3.2% of the population have both migraine and vertigo. The excess comorbidity may be attributed to two factors: 1) vertigo syndromes (including Menière's...
