Abstract
Two scales have been developed and validated in English to evaluate the impact of tremor on daily life, namely Quality of life in Essential Tremor Questionnaire (QUEST) and Essential Tremor Embarrassment Assessment (ETEA). The psychometric properties of the French version of these two scales were assessed for 117 patients with head tremor. Both scales showed excellent acceptability, very good internal consistency (Cronbach's alpha coefficient>0.8) and reproducibility (Lin concordance coefficient>0.8), satisfactory external validity and satisfactory sensitivity to change. In conclusion, the French versions of QUEST and ETEA are comprehensive, valid and reliable instruments for assessing patients with head tremor.

Abstract
Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia is an autosomal dominant leukoencephalopathy related to CSF1R gene mutations. A growing number of clinicoradiologic phenotypes have been described. In this study, we analyzed brain imaging findings in 16 patients with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia to refine radiologic diagnostic clues. T2/FLAIR white matter hyperintensities were present in all patients with frontal or frontoparietal predilection, with asymmetric distribution in more than one-third. Brain atrophy and callosal involvement were almost constant, and corticospinal tract involvement was frequent. Moreover, deep white matter hyperintense dots on DWI and deep punctate calcifications on CT were often found. Conversely, deep gray matter nuclei, external capsules, and brain stem were rarely involved. Our series emphasized the great variability of MR imaging findings seen in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia. A complete imaging screening including DWI, T2*, and CT is mandatory to accurately assess patients with suspected inherited adult-onset leukoencephalopathy.

Abstract
Background: Obstetrical analgesia remains a matter of controversy because of the fear of neurotoxicity of local anesthetics on demyelinated fibers or their potential relationship with subsequent relapses. Objective: To assess the impact of neuraxial analgesia on the risk of relapse during the first 3 months post-partum, with a focus on women who experienced relapses during pregnancy. Methods: We analyzed data of women followed-up prospectively during their pregnancies and at least 3 months post-partum, collected in the Pregnancy in Multiple Sclerosis (PRIMS) and Prevention of Post-Partum Relapses with Progestin and Estradiol in Multiple Sclerosis (POPARTMUS) studies between 1992–1995 and 2005–2012, respectively. The association of neuraxial analgesia with the occurrence of a post-partum relapse was estimated by logistic regression analysis. Results: A total of 389 women were included, 215 from PRIMS and 174 from POPARTMUS. In total, 156 women (40%) had neuraxial analgesia. Overall, 24% experienced a relapse during pregnancy and 25% in the 3 months post-partum. Women with a pregnancy relapse were more likely to have a post-partum relapse (odds ratio (OR) = 1.83, p = 0.02), independently of the use of neuraxial analgesia. There was no association between neuraxial analgesia and post-partum relapse (OR = 1.08, p = 0.78). Conclusion: Neuraxial analgesia was not associated with an increased risk of post-partum relapses, whatever multiple sclerosis (MS) activity during pregnancy.

Abstract
BACKGROUND AND PURPOSE Patients with vascular parkinsonism have higher cognitive decline and more basal ganglia lesions. We aimed to evaluate the relationship of cognitive impairment with functional connectivity between the basal ganglia and cingulate cortex in vascular parkinsonism. MATERIALS AND METHODS Thirty patients (8 with vascular parkinsonism and 22 with Parkinson disease) and 23 controls were enrolled. The Mattis Dementia Rating Scale and the Stroop Task were used to assess cognitive decline. MR imaging examinations included T1-MPRAGE, FLAIR, and resting-state fMRI sequences. MPRAGE was segmented to obtain basal ganglia and cingulate cortex volumes. FLAIR was segmented to obtain white matter hyperintensity lesion volume. Resting-state fMRI sequences were used to compare basal ganglia functional connectivity with the cingulate cortex between patients and controls. RESULTS Patients with vascular parkinsonism exhibited impaired attention, resistance to interference, and inhibitory control and an increased number of errors on the Stroop Task. They also had higher caudate nucleus and white matter hyperintensity lesion volumes, which were positively correlated (ρ = 0.75, P < .0001). Caudate nucleus functional connectivity with the perigenual anterior cingulate cortex was increased in patients with vascular parkinsonism compared with controls and patients with Parkinson disease, and it was positively correlated with the caudate nucleus volume (ρ = 0.44, P = .016). Caudate nucleus functional connectivity with the posterior cingulate cortex was decreased in patients with vascular parkinsonism compared with controls and negatively correlated with the number of errors on the Stroop test (ρ = -0.51, P = .0003). CONCLUSIONS In patients with vascular parkinsonism, cognitive decline could be related to changes of caudate nucleus functional connectivity with the cingulate cortex at resting-state, which may be induced by ischemia-related remodelling.

Abstract
Background: Despite sensitivity of MRI to diagnose multiple sclerosis (MS), prognostic biomarkers are still needed for optimized treatment. Objective: The objective of this paper is to identify cerebrospinal fluid (CSF) diagnostic biomarkers of MS using quantitative proteomics and to analyze their expression at different disease stages. Methods: We conducted differential analysis of the CSF proteome from control and relapsing–remitting MS (RRMS) patients followed by verification by ELISA of candidate biomarkers in CSF and serum in control, clinically isolated syndrome (CIS), RRMS and progressive MS (PMS) patients. Results: Twenty-two of the 527 quantified proteins exhibited different abundances in control and RRMS CSF. These include chitinase 3-like protein 1 (CHI3L1) and 2 (CHI3L2), which showed a strong expression in brain of MS patients, especially in astrocytes and microglial cells from white matter plaques. CSF and serum CHI3L1 levels increased with the disease stage and CIS patients with high CSF (>189 ng/ml) and serum (>33 ng/ml) CHI3L1 converted more rapidly to RRMS (log rank test, p < 0.05 and p < 0.001, respectively). In contrast, CSF CHI3L2 levels were lower in PMS than in RRMS patients. Accordingly, CSF CHI3L1/CHI3L2 ratio accurately discriminated PMS from RRMS. Conclusions: CSF CHI3L1 and CHI3L2 and serum CHI3L1 might help to define MS disease stage and have a prognostic value in CIS.

Abstract
Background and objective: We explored which clinical and biochemical variables predict conversion from clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) in a large international cohort. Methods: Thirty-three centres provided serum samples from 1047 CIS cases with at least two years’ follow-up. Age, sex, clinical presentation, T2-hyperintense lesions, cerebrospinal fluid (CSF) oligoclonal bands (OCBs), CSF IgG index, CSF cell count, serum 25-hydroxyvitamin D3 (25-OH-D), cotinine and IgG titres against Epstein-Barr nuclear antigen 1 (EBNA-1) and cytomegalovirus were tested for association with risk of CDMS. Results: At median follow-up of 4.31 years, 623 CIS cases converted to CDMS. Predictors of conversion in multivariable analyses were OCB (HR = 2.18, 95% CI = 1.71–2.77, p < 0.001), number of T2 lesions (two to nine lesions vs 0/1 lesions: HR = 1.97, 95% CI = 1.52–2.55, p < 0.001; >9 lesions vs 0/1 lesions: HR = 2.74, 95% CI = 2.04–3.68, p < 0.001) and age at CIS (HR per year inversely increase = 0.98, 95% CI = 0.98–0.99, p < 0.001). Lower 25-OH-D levels were associated with CDMS in univariable analysis, but this was attenuated in the multivariable model. OCB positivity was associated with higher EBNA-1 IgG titres. Conclusions: We validated MRI lesion load, OCB and age at CIS as the strongest independent predictors of conversion to CDMS in this multicentre setting. A role for vitamin D is suggested but requires further investigation.

Abstract
INTRODUCTION Cerebrotendinous xanthomatosis, a metabolic leukodystrophy with an autosomal recessive inheritance, is secondary to deficiency of sterol 27-hydroxylase, an enzyme involved in cholesterol catabolism. Classical symptoms include clinical or infraclinical xanthomas affecting the skin and tendons, early cataracts, neurological signs and diarrhea. Brain imaging reveals involvement of the dentate nuclei and periventricular white matter hyperintensities. The diagnosis is based on an increased cholestanol level in serum, confirmed by the presence of a mutation in the CYP27A1 gene. Treatment is based on chenodeoxycholic acid. METHOD We report a retrospective multicentric study of 15 cases of cerebrotendinous xanthomatosis diagnosed in French adults. Clinical, molecular and MRI findings were recorded in all patients. RESULTS The average age at diagnosis was 39years (range 27-65). Disease onset occurred in childhood in 73% of patients and in adulthood in 27%. All patients with a pediatric onset were diagnosed during adulthood (age range 28-65years). Clinical symptoms variably associated cerebellar syndrome, pyramidal syndrome, cognitive decline, epilepsy, neuropathy (sought in 10 of our patients, present in forms in 8), psychiatric disorders, cataract and xanthomas. One patient had an atypical presentation: monoparesis associated with xanthomas. Brain MRI was abnormal in all: findings consisted in T2-weighted hyperintensity of the dentate nuclei (47%), periventricular leuoencephalopathy (73%) which preferentially involved the posterior cerebral part (60%), leucoencephalopathy with a vascular pattern (7%), hyperintensity of the cortico-spinal tracts (53%), globi pallidi, corpus callosum and cerebral atrophy (33%). Serum cholestanol was elevated in 93% of patients. The most frequent mutation was 1183C>T (n=5/15). Under treatment with chenodeoxycholic acid, eight patients improved initially, followed by stabilization in five of them, and worsening in the others. Four patients died. CONCLUSION Patients with the xanthoma-neurological disorder association should be tested for cerebrotendinous xanthomatosis. The disease often begins in childhood with a diagnostic delay but also in adulthood. Involvement of the dentate nuclei is specific but not sensitive and the supratentorial leucoencephalopathy is not specific but with an antero-posterior gradient. A vascular distribution and involvement of the corpus callosum are possible. Serum cholestanol assay is very reliable: an elevated level provides the diagnosis, which must nevertheless be confirmed by molecular biology.

Abstract
INTRODUCTION Cavitary white matter changes are mainly described in leukodystrophies and especially in vanishing white matter disease. Large cavitary lesions are not typical for multiple sclerosis (MS). METHODS We studied MS patients with large cavitary brain lesions. Patient characteristics, disease onset/duration/subtype, expanded disability status scale (EDSS), mini mental state (MMS), vanishing white matter disease genetic analysis, and MRI characteristics of the cavitary lesions were analyzed. RESULTS Twenty patients were analyzed (6 men and 14 women). Mean age at disease onset was 37.6 (range 17-58). Mean disease duration was 10 years (range 2-20). Five patients had initial relapsing-remitting MS and nine patients had primary-progressive MS. Mean EDSS was 5.5 (range 2-8). Mean MMS was 20/30. Vanishing white matter disease genetic analysis was performed and negative in seven patients. Inferior corpus callosum lesions were seen in all patients with available sagittal FLAIR sequences. Cavitary lesions were strictly supratentorial, and located inside the diffuse leukoencephalopathy, with often a posterior predominance. CONCLUSION MS patients with large cavitary lesions seem to represent a MS subgroup, predominantly women, with relatively late disease onset, predominantly primary-progressive type, relatively high EDSS scores, and severe cognitive dysfunction.

Abstract
OBJECTIVE The purpose of our study was to assess the influence of pregnancy on the course of neuromyelitis optica (NMO) and the impact of epidural analgesia and breastfeeding on its activity in the postpartum period. METHODS We performed a retrospective study of patients with NMO diagnosed according to Wingerchuk criteria. We noted the number of relapses during the year before pregnancy (BP), during pregnancy (first trimester, second trimester, third trimester), and the year after (Y + 1: first trimester, second trimester [PP2], and third and fourth trimesters postpartum). Epidural analgesia and breastfeeding were recorded. Disability was evaluated with the Kurtzke Expanded Disability Status Scale (EDSS). The annualized relapse rate (ARR) was calculated. RESULTS We identified 124 patients (85 female) in the French NOMADMUS cohort on November 1, 2010. A total of 20 women (including 25 pregnancies) were informative with complete files. Comparisons between the ARR of each period and BP (1.0 ± 0.09) only showed an increased tendency for PP2 (0.8 ± 0.06, p = 0.07). Epidural analgesia and breastfeeding had no influence on the course of NMO. The EDSS score increased from 1.5 ± 1.7 BP to 2.6 ± 1.9 Y + 1 (p = 0.027). CONCLUSION This study shows that pregnancy influences the activity of NMO, a finding that justifies close medical monitoring. We found no evidence to suggest that either epidural analgesia or breastfeeding has an aggravating effect on NMO.
