Which is characterized by persistent dizziness, unsteadiness, and/or non-spinning vertigo. However, the exact mechanisms remain unclear. In recent years, FMRI studies have provided key insights into the pathogenesis of PPPD. This review summarized functional imaging studies of persistent postural dizziness and its predecessors in recent years and found changes in the activity and functional connectivity of important areas of visual processing, multisensory vestibular and spatial cognition in patients with PPPD. In addition, factors such as stimulation mode, personality traits, mental comorbidities and external vestibular lesions have important effects on brain functional activities and connectivity patterns, and further stratified studies on these factors are needed in the future to further clarify and draw exact conclusions on the pathological mechanism of PPPD.展开更多

Methods： A total of 33 PPPD patients were randomly divided into test group and control group. Two groups of patients were given psychological treatment. The test group was given XJP and the control group was given escitalopram. The course of treatment was 12 weeks. Before and after 4 weeks and 8 weeks and 12 weeks, the dizziness handicap inventory （DHI）, Hamilton anxiety scale （HAMA） and Hamilton Depression scale （HAMD） were used to evaluate the treatment effect. Results： The total scores of HAMA, HAMD, DHI and the respective factor scores of DHI significantly decreased in both groups after 4 weeks of treatment compared with those before the treatment （P 〈 0.01）. The DHI scores and the score of function, physiology at 8-week, 12-week, as well as the HAMA and HAMD scores at 4-week, 8-week, 12-week in the test group were significantly lower than those in the control group （P 〈 0.05）. The incidence of adverse reactions in the test group was significantly lower than the control group （P 〈 0.05）. Conclusion： XJP can improve the clinical symptoms of patients with PPPD. It can both improve the physical and functional symptoms of PPPD and reduce anxiety and depression. In the course of treatment, the adverse reaction of the prescription is less and mild. It has the advantages of high efficiency, safety, low price and easy access to materials.展开更多

Although the subject underwent several examinations to confirm the etiology of her symptoms, the root cause remained unknown. The symptoms were thought to be caused by electromagnetic wave hypersensitivity because the subject experienced uneasiness and dizziness when a cell phone was held close to her body. A cell phone was used to diagnose the collection of harmful electromagnetic waves, and an amalgam filling was determined to be the cause. The amalgam filling was removed under strict protection, and the subject’s symptoms completely disappeared soon after the filling was removed.展开更多

These electronic devices pro-vide many benefits to society. However, there have been a number of reports of electromagnetic hypersensitivity (EHS) related to the use of electronic devices. The symptoms of EHS may include headaches, fatigue, tinnitus, dizziness, memory loss, irregular heartbeat, and skin trouble. Since the pathogenic mechanism of such conditions is not yet clear, further research is required. This report shows how a subject’s dizziness and joint mobility disorder, caused by electromagnetic waves emitted by electronic devices, were cured by removing an onlay from the patient’s mouth and replacing it with a gold alloy onlay. The result indicates that the subject’s symptoms were caused by EHS. Although the symptoms were improved after the dental treatment, the underlying mechanism of the symptoms and the reason why this treatment is successful remain unclear. Further research is required to clarify these issues.展开更多

Most of inhabitants of Yakumo-cho engage in fishery and agriculture as work mainly. We perform questionary survey using an interview vote. The item is “having feeling of dizziness or not”,“quality of hearing” and “having tinnitus or not”. Furthermore, we go for the examination of stabilometry, too. We compared 2015, 2017 with 2005, 2007 among Yakumo-cho inhabitant examination data this time. As a result, participant with a feeling of conscious dizziness got a bad reputation of the hearing consciously. In addition, participant with a feeling of conscious dizziness had tinnitus consciously. Furthermore, the participant with a feeling of conscious dizziness had bad stabilometry result. As a result of having compared ten years later, we understood that stabilometry result worsened if 60s became in 70s with or without a feeling of dizziness consciously. When there is a feeling of conscious dizziness, it is necessary to perform an examination of stabilometry as routine work. In addition, it is necessary to inspect stabilometry if participants have the bad hearing or tinnitus with a feeling of dizziness in particularly.展开更多

Objectives: To assess the efficacy of isolated and combined drug therapy for treating metabolic dizziness and to determine the effect of multidrug treatment. Methodology: We analyzed 100 questionnaires of patients diagnosed with dizziness of metabolic origin. Results: The group treated with vestibular rehabilitation alone showed improvement with 9 months of therapy (p = 0.01). The group treated with vestibular rehabilitation and medication showed improvement with 45 days of therapy (p = 0.01). The group treated with a single type of drug did not show significant improvement. The group treated with several drugs showed improvement with 45 days of therapy (p = 0.03). Conclusion: Combined vestibular rehabilitation resulted in immediate improvement of symptoms without contributing to long-term compensation. Vestibular rehabilitation alone resulted in improve- ment of symptoms over time. Multidrug treatment was beneficial for immediate relief of dizziness.展开更多

However, previous studies have mainly focused on recovery of cerebral blood flow and perfusion in the posterior circulation after interventional therapy. This study examined the effects of functional recovery of local brain tissue on cerebellar function remodeling using blood oxygen level-dependent functional magnetic reso- nance imaging before and after interventional therapy. A total of 40 Chinese patients with severe unilateral vertebral artery orifice stenosis were enrolled in this study. Patients were equally and randomly assigned to intervention and control groups. The control group received drug treat- ment only. The intervention group received vertebral artery orifice angioplasty and stenting ＋ identical drug treatment to the control group. At 13 days after treatment, the Dizziness Handicap Inventory score was compared between the intervention and control groups. Cerebellar function remodeling was observed between the two groups using blood oxygen level-dependent functional magnetic resonance imaging. The improvement in dizziness handicap and cerebellar function was more obvious in the intervention group than in the control group. Interventional therapy for severe vertebral artery orifice stenosis may effectively promote cerebellar function remodeling and exert neuroprotective effects.展开更多

Results: The group treated with vestibular rehabilitation alone showed improvement with 9 months of therapy (p = 0.01). The group treated with vestibular rehabilitation and medication showed improvement with 45 days of therapy (p = 0.01). The group treated with a single type of drug did not show significant improvement. The group treated with several drugs showed improvement with 45 days of therapy (p = 0.03). Conclusion: Combined vestibular rehabilitation resulted in immediate improvement of symptoms without contributing to long-term compensation. Vestibular rehabilitation alone resulted in improve- ment of symptoms over time. Multidrug treatment was beneficial for immediate relief of dizziness.

文摘The theory of"all winds and dizziness belong to the liver"provides a basis for 1ater plysicians to study the etiologic and pathogenesis of vertigo diseases.This theory of pathogenesis suggests that vertigo diseases are most closely related to the liver,so the mechanism can be simply understood as liver and spleen damage.Water dampness is unfavourable for transportation and transformation as dampness gathers phlegm,and liver‘wind’carries phlegm to the ear orifice,causing dizziness,or the ear orifice can be attacked due to the deficiency of yin and hyperactivity of yang in liver and kidney,resulting in sudden dizziness.Based on the pathogenesis theory of liver and spleen damage,the treatment principles should be based on strengthening the spleen and dispelling dampness,eliminating phlegm and extinguishing‘wind’.For‘yang-type'hyperactive liver,nourishing yin and suppressing yang,and the clearing of yang in the ears should always be the standard.

文摘Vertebral artery orifice stenting may improve blood supply of the posterior circulation of the brain to regions such as the cerebellum and brainstem. However, previous studies have mainly focused on recovery of cerebral blood flow and perfusion in the posterior circulation after interventional therapy. This study examined the effects of functional recovery of local brain tissue on cerebellar function remodeling using blood oxygen level-dependent functional magnetic reso- nance imaging before and after interventional therapy. A total of 40 Chinese patients with severe unilateral vertebral artery orifice stenosis were enrolled in this study. Patients were equally and randomly assigned to intervention and control groups. The control group received drug treat- ment only. The intervention group received vertebral artery orifice angioplasty and stenting ＋ identical drug treatment to the control group. At 13 days after treatment, the Dizziness Handicap Inventory score was compared between the intervention and control groups. Cerebellar function remodeling was observed between the two groups using blood oxygen level-dependent functional magnetic resonance imaging. The improvement in dizziness handicap and cerebellar function was more obvious in the intervention group than in the control group. Interventional therapy for severe vertebral artery orifice stenosis may effectively promote cerebellar function remodeling and exert neuroprotective effects.
