are prone to error. Importantly, the study performed by Gerbin recommended a combination of sleep diaries and polysomnography be used in future studies to investigate sleep problems in patients with ET. 6 The aim of our study was to evaluate sleep disturbances and sleep-related events in patients with ET, PD, and controls, using both self-assessment tools and polysomnographic readings. METHODS Study SampleThe ethics committee of Bülent Ecevit University approved this prospective study, and informed consent was obtained from all participants. Between 2010 and 2012, 21 patients with PD who fulfi lled the Parkinson Disease Society Bank criteria, 9 and 16 patients with ET who fulfi lled Movement Disorders BRIEF SUMMARY Current Knowledge/Study Rationale: Sleep problems in ET and PD patients had been investigated in few studies by using subjective assessment tools like self-report questionnaires previously. This study was conducted to evaluate and to compare sleep problems in these two common movement disorders by using PSG which is an objective assessment tool. Study Impact: This study will improve the knowledge about sleep problems in ET and PD patients. Furthermore this is the fi rst study comparing sleep problems in ET and PD patients using PSG.Objective: Sleep problems are a common non-motor complication of Parkinson disease (PD), and patients with essential tremor (ET) share a number of motor and non-motor features of PD. To clarify the relationship between these disorders, we evaluated the sleep problems in patients with ET and PD using assessment scales and objective polysomnographic (PSG) testing. Method: Twenty-one consecutive patients with PD, 16 with ET, and 14 healthy subjects participated in this study and were compared in terms of sleep related complaints, fi nal sleep related diagnosis, and polysomnographic features. Results:The results of our study have shown that patients with PD were more likely than were those with ET to have a history of REM sleep behavior disorders (RBD) (p = 0.001) and excessive daytime sleepiness (p ≤ 0.05). Additionally, PSG data revealed that ET patients had lower mean SpO 2 values (p ≤ 0.05) and REM without atonia (RWA) (p = 0.032) than did patients with PD. Conclusion: This is the fi rst study to use PSG to evaluate sleep problems both in ET and PD patients. The results point out different sleep problems in these two common movement disorders which should be investigated in further studies.

Although Parkinson's disease (PD) and essential tremor (ET) are distinct clinical disorders, their coexistence can sometimes cause diagnostic problems. In this study, we conducted detailed investigations of patients with both ET and PD (ET-PD) and compared their clinical and cognitive profiles with those of patients with only ET or only PD. This study examined three groups of patients: the first group had ET-PD concomitantly (n = 9); the second group had only ET (n = 9); the third group had only PD (n = 10). The groups were compared in terms of demographic characteristics, clinical features, and cognitive functions. With the exception of positive family histories, which were more common in ET-PD than in PD patients, we found no differences among the groups with respect to demographic characteristics (p = 0.044). PD-only patients had more akinetic-rigid type Parkinsonism (p = 0.016), and their levodopa response was better than that of ET-PD patients (p = 0.017). Patients with ET-PD obtained significantly lower scores than those with pure ET on several cognitive tests, suggesting a prominent frontal-type cognitive dysfunction. In conclusion ET-PD patients differed from PD patients, showing more frequent familial tremor histories and lower levodopa responsiveness. This patient population also demonstrated more severe cognitive impairments than pure-ET patients. This result suggests that ET-PD patients are a subset of ET patients with more widespread neurodegeneration, which may indicate the presence of a syndrome that includes overlap between ET and PD.
SMCs are common in people over 55 years of age. Being a woman as well as depression was found to be a risk factor for SMC. Since depression is a treatable condition, these people should be assessed carefully in terms of depressive symptoms. Laboratory parameters, such as hemoglobin, ferritin and free T4 levels should be investigated in patients with SMC. Unlike the other cognitive tests, CDT performance is independent of subjective memory complaints. Elderly patients rarely visit hospital with complaint of SMC, therefore, clinicians should be watchful for this problem.
Background: Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and Unified Dyskinesia Rating Scale (UDysRS) were developed as standard tools to rate Parkinson's disease (PD) and drug-induced dyskinesias of PD. As these scales have become widely used, there is a need for translation to non-English languages. Here we present the standardization for the Turkish translations. Methods: The scales were translated into Turkish and then back-translated to English. These backtranslations were reviewed by the MDS team. After cognitive pretesting, movement disorder specialists from nine centers tested 352 patients for MDS-UPDRS, and 250 patients for UDysRS. Confirmatory factor analyses (CFAs) were used to determine if the factor structures for the reference standards could be confirmed in the Turkish data. The comparative fit indexes (CFIs) for the scales were required to be 0.90 or higher. Exploratory factor analyses (EFAs) were conducted to explore the underlying factor structure without the constraint of a pre-specified factor structure. Results: For both scales, the CFIs were 0.94 or greater as compared to the reference standard factor structures. The factor structures were consistent with that of reference standards, although there were some differences in some areas as compared to the EFA of the reference standard dataset. This may be due to the inclusion of patients with different stages of PD and different cultural properties of raters and patients.Conclusions: These results demonstrate that the Turkish translations of MDS-UPDRS and UDysRS have adequate clinimetric properties. They are established as the official translations and can be reliably used in Turkish speaking populations.
Non-parenchymal neuro-Behçet disease generally affects cerebral venous sinuses, whereas intracranial intracerebral arterial involvement has been rarely reported. But co-involvement of both intracranial intracerebral artery and venous vascular systems in a patient at the same time has not been mentioned before. To the best of our knowledge, this case involving a 25-year-old male with a 7-year history of Behçet disease is the first reported of this type of involvement. He developed occlusion of the basilar artery together with thrombosis of the left sigmoid sinus, distal internal jugular vein, and straight sinus. He was successfully treated with a combination of high-dose steroid and cyclophosphamide. Cranial magnetic resonance angiography demonstrated the resolution of these abnormalities.
