Abstract PDF: Objective
The Scales for Outcomes in Parkinson’s Disease–Cognition (SCOPA-Cog) was developed to screen for cognition in PD. In this study, we aimed to evaluate the validity and reliability of the Korean version of the SCOPA-cog.
Methods
We recruited 129 PD patients from 31 clinics with movement disorders in South Korea. The original version of the SCOPA-cognition was translated into Korean using the translation-retranslation method. The test-rest method with an intraclass correlation coefficient (ICC) and Cronbach’s alpha coefficient were used to assess reliability. The Spearman’s Rank correlation analysis with Montreal Cognitive Assessment-Korean version (MOCA-K) and Korean Mini-Mental State Examination (K-MMSE) were used to assess concurrent validity.
Results
The Cronbach’s alpha coefficient was 0.797, and the ICC was 0.887. Spearman’s rank correlation analysis showed a significant correlation with the K-MMSE and MOCA-K scores (r = 0.546 and r = 0.683, respectively).
Conclusions
Our results demonstrate that K-SCOPA-Cog exhibits good reliability and validity.

Objective
Autonomic symptoms are commonly observed in patients with Parkinson’s disease (PD) and often limit the activities of daily living. The Scale for Outcomes in Parkinson’s disease-Autonomic (SCOPA-AUT) was developed to evaluate and quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in English, into Korean and to evaluate its reliability and validity for Korean PD patients.
Methods
For the translation, the following processes were performed: forward translation, backward translation, expert review, pretest of the pre-final version and development of the final Korean version of SCOPA-AUT (K-SCOPA-AUT). In total, 127 patients with PD from 31 movement disorder clinics of university-affiliated hospitals in Korea were enrolled in this study. All patients were assessed using the K-SCOPA-AUT and other motor, non-motor, and quality of life scores. Test-retest reliability for the K-SCOPA-AUT was assessed over a time interval of 10−14 days.
Results
The internal consistency and reliability of the K-SCOPA-AUT was 0.727 as measured by the mean Cronbach’s α-coefficient. The test-retest correlation reliability was 0.859 by the Guttman split-half coefficient. The total K-SCOPA-AUT score showed a positive correlation with other non-motor symptoms [the Korean version of non-motor symptom scale (K-NMSS)], activities of daily living (Unified Parkinson’s Disease Rating Scale part II) and quality of life [the Korean version of Parkinson’s Disease Quality of Life 39 (K-PDQ39)].
Conclusion
The K-SCOPA-AUT had good reliability and validity for the assessment of autonomic dysfunction in Korean PD patients. Autonomic symptom severities were associated with many other motor and non-motor impairments and influenced quality of life.

Abstract PDF

A decreased cardiac ¹²³I-metaiodobenzylguanidine (¹²³I-MIBG) uptake has been used as a powerful tool to identify Lewy body disease, such as idiopathic parkinson’s disease (IPD). We performed cardiac ¹²³I-MIBG scintigraphy in patient with autosomal recessive juvenile parkinsonism (ARJP) with parkin gene mutation (PARK2). The findings showed normal cardiac ¹²³I-MIBG uptake. Therefore, although the clinical features of ARJP are sometimes quite similar to those of late-onset IPD, cardiac ¹²³I-MIBG scintigraphy may be used as a valuable tool to identify patients with IPD and to distinguish them from patients with other parkinsonian syndromes.

We experienced a 50-year-old patient with ATM associated with Sjögren’s syndrome. Furthermore, the patients complained painful spasms and rigidity of left lower limb which begun after episode of ATM.

Abstract PDF: We report a 70-year-old man who manifested with hemidystonia associated with focal status epilepticus. The subsequent clinical symptoms and signs including rapid progressive dementia, and generalized myoclonus and the presence of 14-3-3 protein in cerebrospinal fluid, typical magnetic resonance imaging and eletroencephalography findings provide the evidences for diagnosis of probable Creutzfeldt-Jakob disease (CJD). Movement disorders or epilepsy rarely occur in the early stage of CJD. Furthermore, co-occurrence of both disorders in the early stage has been hardly reported. To the best of the authors’ knowledge, this is the first report in Korea of CJD presenting as dystonia. Our case suggests that CJD can present with a variety of movement disorders.
