Prevalence of Neurological Disorders in a Japanese Town

Abstract

The prevalence of all neurological disorders in a Japanese town was calculated, with a result of 91.1 per 1,000 population. The prevalence of cerebrovascular disease was 28.8; myelopathy and/or radiculopathy caused by deformity of the spine or disc herniation, 23.9; neuralgia, 11.5; dementia, 10.4; peripheral nerve disturbance, 5.5; epilepsy, 4.4; Parkinson''s disease, 2.0; mental retardation, 2.9; brain/spinal tumor, 1.4; headache, 10.8, and vertigo/dizziness, 4.4. The prevalence of headache and vertigo/dizziness was also calculated from the results of the questionnaires sent to inhabitants: headache, 79.6, and vertigo/dizziness, 60.8. Neurological disorders are common in Japan and likely to continue to increase.

Epidemiology of dizziness in northern Poland – The first Polish neurootologic survey of the general population

“…Nakashima et al [2] conducted a postal survey in 1996 that reached 7,685 respondents, and concluded that dizziness affected 6.1% of them. Neuhauser et al [3] conducted a telephone survey in 2005 that reached 4,869 respondents, and concluded that 7.8% of the respondents suffered from dizziness.…”

“…It is difficult to define, impossible to measure, a challenge to diagnose and troublesome to treat. It is ranked among the most common complaints in primary care office practice, affecting approximately 6.1% -21% of the general population [1,2,3]. Its prevalence increases with age and may be as high as 30% in those over 65 years of age [4].…”

Epidemiology of Balance Symptoms and Disorders in the Community

“…Two studies inquired about dizziness in the last month with estimates of 15.8 (15) and 23% (1), with a figure of 10.9% experiencing dizziness severe enough to interfere with normal activities (1). The highest estimate of rate of dizziness is 85% over 18 months (16) and 59.2% over 12 months (17), and the lowest is 0.44% (18). However, this last study did not specify the time period over which respondents were required to report symptoms and so the figure is difficult to interpret meaningfully.…”

Review on Physical Therapy for Patients with Vestibular Disorder

“…12,13 In particular, number of patients with vestibular dysfunction reached 850,000, which mean 54% of increment from five years earlier(Previous studies reported that the prevalence of dizziness for 1 year ranged from 6.1% to 27%. 14,15 The prevalence or vestibular dysfunction has shown 35.4%…”
