Distinctive sleep complaints and polysomnographic findings in antibody subgroups of autoimmune limbic encephalitis.

INTRODUCTION: Sleep disturbances are being increasingly recognized in association with autoimmune encephalitis (AIE). We investigated the prevalence of sleep-related symptoms and polysomnographic features of patients with AIE and the long-term outcomes in these patients in a multi-center, prospective study from Turkey. METHODS: We prospectively evaluated patients with definite AIE in a common database including demographics, AIE-related and sleep-related symptomatology. Maximum and latest modified Rankin scores (mRS) and Liverpool Outcome Score (LOS) were noted. RESULTS: Of 142 patients, 87 patients (61.3%) fulfilled the criteria for definite AIE (mean age, 46.8+18.8 years; 51.7% women; mean disease duration, 21.0+38.4 months). 78.9% of patients had at least one or more new onset or worsened sleep-related symptomatology: insomnia (55.3%), excessive daytime sleepiness (EDS, 28.0%), sleep apnea (18.7%), REM sleep behavior disorder (RBD, 17.3%), restless legs syndrome (10.7%) and oneiric stupor (9.3%). Sleep efficiency, N3 and REM sleep were decreased and N1 sleep was increased in patients with Ab[+] AIE. LOS points were highest in those with insomnia and sleep apnea, and lowest in those with EDS, RBD and oneiric stupor. RBD and sleep apnea were more common in anti-LG1 Ab[+] group than anti-NMDAR Ab[+] group. Index of periodic leg movements was highest in anti-LG1 Ab[+] group. Patients with EDS and oneiric stupor had more common memory problems. Maximum and latest mRS scores were positively correlated with EDS and oneiric stupor. EDS, RBD and oneiric stupor were negatively correlated with LOS points. CONCLUSION: Our study emphasizes the presence and importance of early diagnosis of sleep disturbances in AIE in regard to their deteriorative influences on disease prognosis.

An invisible cause of disability: stigma in migraine and epilepsy.

OBJECTIVE: Our purpose was to identify the ratio and severity of stigmatization in patients with migraine and epilepsy. We also collected demographic and clinical data to search for possible facilitators. METHODS: In total, 196 patients with migraine and 60 patients with epilepsy were enrolled. Neuro-QoL Stigma Scale was applied in an office setting by a neurologist in 3 different centers. Stigma scores were calculated as standardized T scores (total, enacted, and internalized). Demographics, clinical characteristics, and treatment status of the patients were also compared in terms of stigma scores. Kruskal-Wallis test or Mann-Whitney U tests were applied for comparisons. Spearman's correlation analysis was used for the evaluation of inter-parameter correlations. RESULTS: Eighty-one percent of the patients with epilepsy and 72% of the patients with migraine reported being stigmatized. Total T scores were significantly higher in the epilepsy group (50.78 ± 9.1) than the patients with migraine (44.9 ± 7.62), also than the chronic (45.86 ± 8.76) and episodic (44.7 ± 7.27) migraine subgroups (p < 0.05). T scores increased as the duration of disease increased; however, this correlation was significant for the epilepsy group only (p < 0.05). Migraine group with prophylactic treatment had significantly higher scores than the migraineurs without preventive therapy (p < 0.05). Enacted T scores were higher than internalized T scores in all analyzed groups and subgroups (p < 0.05). CONCLUSION: Patients with migraine and epilepsy are subjected to stigma. The ratio and intensity can change in different countries. We need to increase the awareness and search for better solutions. The standardized tests are important to compare results between studies.

Hypercholesterolemia as one of the risk factors of intracerebral hemorrhage.

Stroke is still a major cause of morbidity and mortality throughout the world, although better stratification and treatment modalities are being developed. As compared to ischemic stroke, intracerebral hemorrhage (ICH) possesses many unknown data and lacks guidelines for better prophylaxis. In this study, we aimed to investigate patients with ICH hospitalized in our neurology department within 5 years in terms of risk stratification. A total of 4,449 patients were hospitalized; 1,378 of patients (31%) were diagnosed as having cerebrovascular disease and of these 165 patients (3.7%) had ICH. The risk factors of patients with ICH were investigated and compared with age- and gender matched 75 healthy subjects. We observed that hypercholesterolemia (p = 0.002) was one of the most common risk factors in patients with ICH as compared to controls, together with hypertension (p = 0.010). On the other hand, hypolipidemia (LDL-cholesterol level < 50 mg/dl) was not present in any of the patients. As our purpose as neurologists is to reduce the occurrence and fatal outcome of cerebrovascular events, we aimed to emphasize the importance of risk factors to be well defined, for which every effort should be exhibited for both primary and secondary prevention.
