Acute confusional states, cerebrovascular disease, peripheral neuropathies and seizure are the most common. We report a rare case of SLE-related myelopathy in teenager girl. Case report: 16 years-old teenager girl, with no previous health history, presented 8 days before her admission, rapidly progressive flaccid tetra paresis with paresthesia and sphincter disturbance. These symptoms were associated to polyarthritis and facial lupus discoid lesion. Spinal MRI objectified Longitudinal Extensive Transverse Myelitis (LETM) to more than 12 vertebral segments. Cerebrospinal Fluid (CSF) showed normal cytology with mild high protein level (0.8 g/l). Immunologic tests went positive to anti-nuclear and anti-DNA antibodies, with negative anti-aquaporin 4 and anti-MOG antibodies. Several infectious serologies went negative. The diagnosis of acute LETM secondary to NPSLE was established. The patient was treated by bolus methylprednisolone and cyclphosphamide, relayed by oral prednisolone. The course was favorable with clinical and radiological improvement, apart from sequelar spinal atrophy on the MRI. Discussion: Neuropsychiatric Systemic Lupus Erythematosus (NP SLE) is one of the most challenging forms of SLE, as one-third of patient with NPSLE are primary manifestation of lupus autoimmunity. Lupus myelitis is occurring in 1 to 2% of SLE patients. In above 22% of reported cases, LETM was the revealing syndrome of SLE. Several differential diagnoses cause LETM, and must be eliminated according to clinical peculiarities and adequate para clinical tests (infection, neuromyelitis optica spectrum disorders, Sjogren’s syndrome, paraneoplastic syndrome). Early methyprednisolone bolus and cyclophosphamid have shown better prognosis with sensori-motor and sphincter improvement. Conclusion: LETM may be the initial presentation of NPSLE. The absence of other systemic symptoms makes the diagnosis a real challenge. This went to procession of clinical and biological arguments. Randomized studies should be led, to report clear guidelines concerning therapies and prognosis.","PeriodicalId":16455,"journal":{"name":"Journal of Neurology and Neurophysiology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86418187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve its diagnosis and remediation outcomes, development of objective hearing methods offer new ways of optimizing care strategy. Complementary to the classical click-evoked brainstem and cortical responses, interest grows regarding the speech auditory brainstem responses, whose components, namely the onset and frequency following responses, are proposed as biomarkers of speech encoding at the brainstem level. To improve the understanding of auditory processing in the human brainstem and its effect on cortical processing, we used a multimodal set-up and recorded brainstem and cortical potentials in response to click stimuli and speech stimuli presented at different stimulation intensities in normal hearing adults. We hypothesized that even though click- and onset responses of the speechauditory brainstem responses share some similarities; their underlying mechanisms are in some point distinct. We also presumed that using a noninvasive method we could assess the generators underlying click, onset and frequency following responses and the time wise influence of brainstem encoding on cortical processing of click and speech stimuli. Results showed evidence regarding mechanisms underlying onset response and frequency following response components at the brainstem level. A direct time wise relationship between subcortical encoding and cortical encoding was revealed: cortical activity in the left cortex was related to the onset response latency at the brainstem level. These results highlight the potential use of new methods in speech processing electroencephalographic studies and provide qualitative and topographical data regarding subcortical and cortical auditory processing network.","PeriodicalId":16455,"journal":{"name":"Journal of Neurology and Neurophysiology","volume":"23 1","pages":"1-18"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74535073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the application of repetitive Transcranial Magnetic Stimulation (rTMS) to the primary motor cortex (M1) has been used to promote functional recovery in stroke patients with hemiparesis. High-frequency rTMS (5 Hz or greater) was applied over the affected hemisphere to reactivate hypoactive regions. Because of recent advances in MRI technology and, in particular, the gradient coils, high-frequency whole brain rTMS-fMRI is possible. The use of interleaved rTMS-fMRI during stimulation at a frequency of 5 Hz aids in understanding how the brain is modulated during stimulation. Method: We measured BOLD signal changes in whole brain during interleaved rTMS-fMRI (5Hz) using 3T MRI. Image processing and statistical analyses were carried out using the Statistical Parametric Mapping (SPM8) software. Results: Distinct BOLD signal changes extending to the remote motor network during 5 Hz-rTMS over the M1 were successfully demonstrated using interleaved rTMS-fMRI. Negative BOLD responses were observed in the contralateral M1, the dorsal premotor cortex (PMd), and the bilateral supplementary motor cortex (SMA), even though no significant BOLD signal changes were observed in the stimulated M1. The negative BOLD responses gradually became marked during (3 mins 57 sec). Therefore, long-lasting plastic changes may occur within 4 mins. Negative BOLD responses in remote regions away from the directly stimulated M1 suggest that subthreshold high frequency rTMS over the motor cortex induced neuromodulation via neuronal networks. Conclusion: The remarkable negative BOLD responses in the contralateral M1 induced by high-frequency rTMS may be useful for identifying a treatment strategy involving M1 stimulation.","PeriodicalId":16455,"journal":{"name":"Journal of Neurology and Neurophysiology","volume":"105 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85888591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most frequently impaired functions are information processing speed, attention and memory. Dementia is uncommon but may reveal a MS. We reported a 47-year-old woman suffering since 8 months of headache with a progressive amnesia, temporospatial disorientation and behavioral disorders. On examination, we found dementia syndrome and a frontal syndrome. Brain MRI showed a T2 hyperintensity multifocal ovoid lesions with enhancement in the periventricular white matter and in the corpus callosum. Diagnostic hypotheses were ADEM or MS. Isoelectric focusing revealed oligoclonal bands and elevated IgG index. She was treated with intravenous methylprednisolone 1 g daily for five consecutive days. There was a regression of the symptomatology but 4 months after diagnosis, the patient presented with a postural instability, gait difficulty, terminal intention tremor and dysmetria. A diagnosis MS was considered and she was given interferon. The concept of MS being a dementing illness is not novel. Neurologists are well aware that patients with MS may present with cognitive impairment.
