 PDF Supplementary Material
- Anxiety, depression, or other psychiatric symptoms can be the primary cause of dizziness and the secondary complication of dizziness. Regardless of precedence or consequence, dizziness is closely associated with the psychiatric problem. On this ground, this chapter reviews the association between dizziness and anxiety and the treatment for dizziness with psychiatric symptoms.

Abstract
PDF
- Central vertigo is the common symptom resulting from abnormalities in the central nervous system, caused by various diseases, which include neurodegenerative, vascular, inflammation, infection, tumor, paraneoplastic, toxic, or metabolic disorders. Since the treatment of central vertigo depends on the causes, an accurate diagnosis should be preceded the treatment through a detailed neurotologic examination and laboratory evaluation. Also, it is important to identify and document the neurologic findings accompanied by central vertigo, because some medication focuses on the ocular motor abnormalities as nystagmus or saccadic intrusion. Here, we will review the medical treatment for central vertigo.

Abstract

- Objectives
To survey the satisfaction of customized vestibular exercise using virtual reality system with mobile head-mounted display (HMD) in the elderly patients with chronic unilateral vestibulopathy, we analyzed questionnaires before and after exercise.
Methods
Sixteen patients (male, 6; median age, 69 years [interquartile range, 65–75 years]) with chronic unilateral vestibulopathy were prospectively enrolled from March 1 to December 31 in 2018. They exercised once a week for 20 to 25 minutes for 4 weeks using the HMD inserted the virtual reality exercise program. Dizziness visual analogue scale (DAS), Korean vestibular disorders activities of daily living scale (ADL), and visual vertigo analogue scale (VVAS) were performed before and after the exercise. After all of the program, the patients were surveyed to measure the satisfaction for the tool and effect of exercise.
Results
DAS, ADL, and VVAS were significantly improved after the vestibular exercise. No one answered unsatisfactory, and at least 62.5% of the patients satisfied the used tool and exercise program. The patients of 50% answered that they satisfied or very satisfied to the efficacy of exercise program. The patients who recovered VVAS more after the exercise were more satisfied to our tools and efficacy of exercise program.
Conclusions
Customized vestibular exercise using virtual reality system with HMD can not only improve dizziness and quality of life, but also made more satisfied to the elderly patients with chronic unilateral vestibulopathy.

Abstract
PDF
- Anti-GQ1b antibody syndrome, including Miller Fisher syndrome, Guillain-Barré syndrome with ophthalmoplegia, Bickerstaff’s brainstem encephalitis, and acute ophthalmoplegia without ataxia, has overlapped clinical symptoms and mostly associated with anti-GQ1b immunoglobulin (Ig) G antibody. We report two cases of anti-GQ1b antibody syndrome mainly presenting with a severe headache. The 60-year-old man was admitted for severe headache and gait disturbance. Neurological examination revealed limb and truncal ataxia, areflexia, nystagmus, and ophthalmoplegia. Serum IgG anti-GQ1b antibody was positive. He recovered after intravenous (IV) immunoglobulin and steroid. The 23-year-old man suffered from severe headache (visual analogue scale=10) within the periorbital area. Ophthalmoplegia with gaze-evoked nystagmus were revealed. Serum IgG anti-GQ1b and anti-GT1a antibodies were positive. Headache was improved by IV immunoglobulin and steroid. The pathophysiology of headache in anti-GQ1b antibody syndrome is largely unknown. The affected nerve or structures in the brainstem including the trigeminovascular system may induce intractable severe headache.

Abstract

- Objectives
Bilateral vestibulopathy is characterized with unsteadiness and oscillopsia when walking or standing, worsening in darkness and/or on uneven ground. To establish the effect of customized vestibular rehabilitation in bilateral vestibulopathy, we analyzed the questionnaires and functional status before and after treatment.
Methods
Among 53 patients with customized vestibular rehabilitation from January 1st to November 30th in 2018, 6 patients (3 males; median age, 71 years; range, 54–75 years) who regularly exercised with good compliance were retrospectively enrolled. They were educated and trained the customized vestibular rehabilitation once a month or two by a supervisor during 40 minutes, and then exercised at home for 30 minutes over 5 days in a week. Dizziness handicap inventory (DHI), Korean vestibular disorders activities of daily living scale (vADL), Beck’s depression index (BDI), test for dynamic visual acuity (DVA), and Timed Up and Go test (TUG) were performed before and after the customized vestibular rehabilitation.
Results
The patients exercised for median 5.5 months (range, 2–10 months) with the customized methods of vestibular rehabilitation, which included gaze and posture stabilization and gait control exercises. DHI score and TUG was improved after rehabilitation (DHI before vs. after rehabilitation=33 vs. 16, p=0.027, TUG before vs. after rehabilitation=12 vs. 10, p=0.026). BDI, DVA, and vADL scores did not differ between before and after treatment.
Conclusions
Customized vestibular rehabilitation can improve dizziness and balance state in bilateral vestibulopathy. The steady exercises adapted individual peculiarities is the most important for vestibular rehabilitation.

Abstract
- Abnormal eye movements in unconscious patients serve as crucial diagnostic instruments, offering insights into the function of the central nervous system. Understanding these movements can aid in diagnosing the cause of unconsciousness, localizing brain lesions, and predicting outcomes. We report a patient who presented with spontaneous horizontal nystagmus unaffected by light in delayed post-hypoxic encephalopathy. Video-oculography showed exponentially increasing slow phases, with an amplitude ranging from 3° to 9° and a frequency of 0.5 Hz. Based on the results of oculography and neuroimaging, persistent horizontal nystagmus in our patient may be ascribed to an unstable neural integrator, possibly caused by disrupted cerebellar feedback mechanisms for horizontal gaze holding.
