A nationwide survey of patients in Japan with spinocerebellar degenerations (SCD), including SDS and SND, was conducted from 1988 to 1989. The survey consisted of two parts. The first revealed that the estimated total number of patients with SCD in Japan was 5,050 (range: 4,100-6,000) with an estimated prevalence of 4.53 per 100,000 in 1987. The second part investigated the neurological and functional status of patients with SCD. The percentages of those belonging to each subtype of SCD were: OPCA; 34.4%, LCCA; 15.2%, MHCA; 12.6%, HHCA; 7.5%, SDS; 7.0%, HSP; 3.9%, DRPLA; 2.5%, FA; 2.4%, MJD; 2.0% and SND; 1.5%. Compared with European epidemiological studies Japan had a higher proportion of non-hereditary types of SCD. Various clinical features of SCD subtypes were compared grouped by pathological lesion and heredity. HHCA and LCCA: cerebellar ataxia predominated in all stages, and neurological signs other than cerebellar ataxia were rare. MHCA, DRPLA and MJD: in the early phase ataxia was the most common symptom in MHCA, the AC form of DRPLA and MJD, but ataxia was less common and chorea or epilepsy were often observed in ME and PH forms of DRPLA. Other frequently observed clinical features were parkinsonian rigidity in MHCA, abnormal movements and posture in DRPLA and MJD, and disturbances of eye movements in MHCA, the AC form of DRPLA and MJD. OPCA, SDS and SND: dominant clinical features were cerebellar ataxia in OPCA, autonomic disturbance in SDS, and parkinsonian rigidity in SND. FA and HSP: both were rare in Japan. Clinical features related to supra-supinal lesions were frequently observed in FA. Functional status of SCD: the severity of illness was significantly associated with the level of independence in each item of ADL. Activities not requiring dynamic balance were performed independently for a longer period than those requiring dynamic balance. Among SCD subtypes, functional prognosis was poorest in non-hereditary, multi-systemic types (OPCA, SDS and SND) followed by hereditary multi-systemic types (MHCA, DRPLA and MJD), and better in spinal types (FA and HSP) and cerebellar types (HHCA and LCCA).

A nationwide epidemiological study on spinocerebellar degeneration (SCD) including multiple system atrophy was performed in Japan from 1988 to 1989. The national prevalence rate of SCD was estimated to be 4.53/100,000 in 1987. The percentage of patients with each subtype of SCD was; olivopontocerebellar atrophy (OPCA) 34.4%, Menzel type of hereditary cerebellar ataxia (MHCA) 12.6%, Holmes type of hereditary cerebellar ataxia (HHCA) 7.5%, Shy-Drager syndrome (SDS) 7.0%, hereditary spastic paraplegia (HSP) 3.9%, dentatorubro-pallidoluysian atrophy (DRPLA) 2.5%, Friedreich ataxia (FA) 2.4%, Joseph disease (JD) 2.0%, and striatonigral degeneration (SND) 1.5% in decreasing order. In Japan, compared to European countries, non-hereditary types seemed to be commoner than hereditary types. OPCA was the most common disorder, but FA which is the most common disorder in European countries was found to be rare in Japan. We grouped the SCD on the basis of common pathological lesions, and compared the clinical features in the same group according to the severity stages. Similarity and differences in non-hereditary cerebellar form (LCCA, HHCA), multiple system atrophy (OPCA, SDS, SND), hereditary cerebello-brainstem form (MHCA, JD, DRPLA), and hereditary spinal from (FA, HSP) were elucidated. As to the functional status in SCD, there was a significant association between the severity of illness and the level of independence in each item of ADL, and also between poorer functional prognosis and presence of extrapyramidal and autonomic signs.

Cerebellar ataxia (hereinafter referred to as CA) designate a group of neurodegenerative disorders. CA is distinguished into a group of hereditary and non-hereditary disorders. CA shows clinically progressive features and accompanies various neurological abnormalities. However, there are very few studies and case reports in Korean patients. To estimate the prevalence rate and current status of the CA patients in Korea, we used data from the Health Insurance Review and Assessment Service (HIRAS) and from the National Health Insurance Corporation. To evaluate the functional status of CA patient in Korea, we conducted a simple random sampling among the 500 members of Korea Ataxia Society registered on its homepage. We evaluated the functional status and degree of disturbance to their everyday life with modified Rankin scales and Barthel ADL index. Using the data from HIRAS, we could estimate the prevalence rate of CA patients in Korea as 8.29 patients/100,000 persons. The prevalence rate of hereditary and non-hereditary cerebellar ataxia was 4.99 patients/100,000 persons and 3.30 patients/100,000 persons, respectively. Data on rare intractable diseases reported by the Korean Centers for Disease Control and Prevention in 2006 suggested that the number of CA patients who have visited medical institutes was almost doubled for the 2-year period. The medical expense and hospital stay also increased 4.5- and 3-fold, respectively. After severity evaluation with modified Rankin scales and Barthel ADL index, we found that most CA patients in Korea have ataxia-related difficulties in their everyday life.

The ABC method is a basic and simplified form of behavioural modification therapy for use by nurses. ABC refers to the identification of Antecedent events, target Behaviours, and Consequent events. A single-case experimental AB design was used to evaluate the effects of the ABC method on a woman diagnosed with olivo-ponto-cerebellar ataxia. Target behaviour was verbal aggressive behaviour during ADL care, assessed at 9 time points immediately before implementation of the ABC method and at 36 time points after implementation. A randomisation test showed a significant treatment effect between the baseline and intervention phases (t = .58, p = .03; ES [Nonoverlap All Pairs] = .62). Visual analysis, however, showed that the target behaviour was still present after implementation of the method and that on some days the nurses even judged the behaviour to be more severe than at baseline. Although the target behaviour was still present after treatment, the ABC method seems to be a promising tool for decreasing problem behaviour in patients with acquired brain injury. It is worth investigating the effects of this method in future studies. When interpreting single-subject data, both visual inspection and statistical analysis are needed to determine whether treatment is effective and whether the effects lead to clinically desirable results.

A 63-year-old female who developed dizziness, diplopia and subsequent gait disturbance from September X-1 year was analyzed. The first neurological findings in May X year revealed cerebellar ataxia, weakness in the proximal limbs, decreased tendon reflexes, and autonomic symptoms (ADL:mRS 3). Furthermore, an incremental phenomenon was observed in the repetitive nerve stimulation test, and she was diagnosed with Lambert-Eaton myasthenic syndrome (LEMS) based on the serum P/Q-type calcium channel (VGCC) antibody positivity. In addition, small cell lung cancer was detected by chest CT and bronchoscopy, and her cerebellar ataxia was diagnosed as paraneoplastic cerebellar degeneration (PCD). Therefore, the patient underwent chemotherapy and radiotherapy from June in X year. Six months after initiation of treatment, her cerebellar ataxia had almost disappeared and she could walk without assistance (ADL:mRS 1). The P/Q-type VGCC antibodies were also negative at that time. Cases wherein cerebellar ataxia resolved almost completely in parallel with disappearance of the serum P/Q-type VGCC antibodies are of great interest. We conducted a systematic literature review of PCD-LEMS cases in Japan reported since P/Q-type calcium channel antibody measurement was reported in 1995. As a result, 13 cases (including our study) that concurrently displayed cerebellar ataxia and LEMS were selected. The average age of the 13 patients (10 males and 3 females) was 61.5 years. Small cell carcinoma was complicated in 11 patients (10 in the lung and 1 in the oropharynx); in the other 2 patients, cancer was not found at the time of reporting (the observation period was as short as 1-2 months). The time from onset to treatment ranged between 1 week and 10 months. While 1 of the 13 patients developed cerebellar ataxia during the subsequent course of the treatment, the remaining 12 had already developed cerebellar ataxia and LEMS symptoms, although their main neurologic finding was cerebellar ataxia and they were subsequently diagnosed with LEMS after electrophysiological testing and autoantibody detection. Small cell carcinoma was found in 11 patients. We define the pathology following such a certain clinical course as PCD-LEMS. The P/Q-type VGCC antibodies were positive in 11 of the 13 cases, although their antibody titers were not necessarily very high. Treatment for the associated small cell carcinoma might have improved the neurological findings in 9 of the 11 PCD-LEMS patients. The P/Q-type VGCC antibodies were measured before and after the treatment. The PCD-LEMS symptoms improved in all patients and their antibody titers decreased. These findings indicate that P/Q-type VGCC antibodies are involved in the pathology of PCD-LEMS. Appropriate and timely treatment, at least in PCD-LEMS patients in Japan, that actively treats any associated cancer can be expected to improve not only life prognosis but also cerebellar ataxia.
