Huntington’s disease (HD) is a devastating neurodegenerative disease caused by cytosine-adenine-guanine trinucleotide repeat expansion in the huntingtin gene. Growing evidence supports the regulatory functions of long noncoding RNAs (lncRNAs) in the disease process, but little is known about the association between lncRNAs and neuronal death in HD. Here, we(More)
Contactin-associated protein-like 2 (CASPR2) is one of the target antigens of voltage-gated potassium channels (VGKC) complex antibodies. There has been relatively little information in the literature regarding CASPR2 autoimmunity, especially in Asian population. We investigated the presence of CASPR2 antibodies in patients with presumed autoimmune(More)
BACKGROUND Two clinical scoring systems, the status epilepticus severity score (STESS) and the epidemiology-based mortality score in status epilepticus (EMSE), are used to predict mortality in patients with status epilepticus (SE). The aim of this study was to compare the outcome-prediction function of the two scoring systems regarding in-hospital mortality(More)
MicroRNA-206, which suppresses the expression of brain-derived neurotrophic factor, is known to be elevated in the brains of Alzheimer's disease (AD) patients. We performed intranasal biopsy of the olfactory epithelia of early dementia patients (n = 24) and cognitively healthy controls (n = 9). Patients with significant depression (n = 8) were analyzed(More)
OBJECTIVE Secondary bilateral synchrony (SBS) indicates bilaterally synchronous epileptiform discharges arising from a focal cortical origin. The present study aims to investigate SBS in partial epilepsy with regard to surgical outcomes and intracranial EEG findings. METHODS We retrospectively reviewed consecutive patients who underwent epilepsy surgery(More)
We aimed to evaluate the prevalence of antineuronal antibodies in a nationwide cohort of patients with encephalopathy of unknown etiology. We screened 1699 patients with idiopathic encephalopathy who were referred from 70 hospitals across Korea for autoimmune synaptic and classic paraneoplastic antibodies. Those with cerebellar degeneration, sensory(More)
OBJECTIVE To determine efficacy and safety of rituximab treatment as a second-line immunotherapy treatment for autoimmune limbic encephalitis (ALE) and to determine factors associated with functional improvement and favorable outcome following rituximab treatment. METHODS We recruited 80 patients with ALE who were treated with rituximab as a second-line(More)
A considerable portion of autoimmune encephalitis (AE) does not respond to conventional immunotherapies and subsequently has poor outcomes. We aimed to determine the efficacy of tocilizumab, an anti-interleukin-6 antibody, in rituximab-refractory AE compared with other treatment options. From an institutional cohort of AE, 91 patients with inadequate(More)
The aim of this study was to compare serum and cerebrospinal fluid (CSF) cytokine/chemokine levels between anti-NMDAR and anti-LGI1 encephalitis patients. Samples from fourteen anti-NMDAR encephalitis patients, ten anti-LGI1 encephalitis patients, and ten controls were analyzed for the following cytokines/chemokines: IL-1b, IL-2, IL-4, IL-5, IL-6, IL-10,(More)
OBJECTIVES We evaluated and compared the 3-year retention rates of levetiracetam (LEV), topiramate (TPM), and oxcarbazepine (OXC) in patients with epilepsy in routine clinical practice. METHODS We retrospectively reviewed medical records of patients with epilepsy who were newly prescribed LEV, TPM, or OXC from 2006 to 2010. The retention rates were(More)
