Purpose: We evaluated long-term seizure outcomes of antiseizure medications (ASMs) and risk factors for drug resistance in patients with adult-onset epilepsy associated with cerebral cavernous malformation (CCM).
Materials And Methods: This retrospective observational study included patients newly diagnosed with adult-onset focal epilepsy associated with CCM. Patients received individualized treatments with ASMs.
Background: Little is known regarding the effects of continuous positive airway pressure (CPAP) on sleep misperception in obstructive sleep apnea (OSA).
Methods: Sleep state perception was measured by subtracting the objective total sleep time from the subjective sleep duration. Sleep underestimation and overestimation were defined as ± 60 minutes sleep perception.
Purpose: We evaluated whether the relationship between general self-efficacy and depressive symptoms in patients with epilepsy differed depending on age, sex, and seizure status.
Methods: This multicenter, cross-sectional study was conducted on 299 adults with epilepsy, using the Beck Depression Inventory (BDI) and the General Self-efficacy Scale (GSES). We performed stepwise linear regression analysis and analysis of covariance with interaction terms.
Purpose: To determine whether sex affects the relationship between aggression and symptoms of depression and anxiety in adults with refractory focal epilepsy.
Methods: This cross-sectional study was conducted in 85 adults with refractory focal seizures, which are defined as one or more seizures recurring per month even when the patient is treated with two or more antiseizure medications. We used the Buss-Perry Aggression Questionnaire (AQ) and the Hospital Anxiety and Depression Scale (HADS) to evaluate aggression and symptoms of depression and anxiety, respectively.
Objective: We determined whether the severity of sleep apnea is associated with symptoms of depression and anxiety in patients with obstructive sleep apnea (OSA) and whether symptoms of OSA, other than respiratory events, are associated with depression and anxiety symptoms.
Methods: Depressive and anxiety symptoms were defined as a Patient Health Questionnaire-9 score of ≥10 and a Generalized Anxiety Disorder-7 score of ≥8, respectively. Sleep apnea severity and rapid eye movement-related OSA were evaluated using the apnea-hypopnea index (AHI).
Purpose: This study assessed whether patients with epilepsy have a higher level of impulsivity than healthy controls, and compared impulsivity among patients with different subtypes of epilepsy.
Methods: The multicenter study included 108 subjects with epilepsy and 56 healthy volunteers. Subjects were evaluated by the Barratt Impulsiveness Scale-11 (BIS-11) and Patient Health Questionnaire-9, with BIS-11 scores analyzed as both dichotomized and continuous variables.
Purpose: This study assessed the strengths of association among perceived stress, felt stigma, and depression in adults with epilepsy, and evaluated whether felt stigma altered the association between perceived stress and depression.
Methods: This multicenter, cross-sectional study included adults with epilepsy. Depression was assessed using the Beck Depression Inventory (BDI), and perceived stress was evaluated using the 10-item Perceived Stress Scale.
Background And Purpose: To identify sex differences in daytime sleepiness associated with apnea severity and periodic limb movements during sleep (PLMS) in subjects with obstructive sleep apnea (OSA).
Methods: This study used the Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Sleep Hygiene Index (SHI) in logistic regression analyses with interaction terms. Severe OSA, excessive daytime sleepiness (EDS), and PLMS were defined as an apnea-hypopnea index of ≥30, an ESS score of ≥11, and a periodic limb movements index of >15, respectively.
Purpose: This study assessed whether seizure severity and social anxiety were related to self-disclosure or concealment behaviors independent of felt stigma in Korean adults with epilepsy.
Methods: This multicenter, cross-sectional study used the Disclosure Management Scale (DMS), the short forms of the Social Phobia Scale (SPS-6) and Social Interaction Anxiety Scale (SIAS-6), and the Stigma Scale-Revised to evaluate Korean adults with epilepsy. Seizure severity was measured as a composite variable, and multivariate linear regression analyses were performed to assess whether seizure severity and social anxiety were related to concealment behaviors.
Purpose: Little is known regarding the prevalence of sleep state misperception and the factors related to this in patients with obstructive sleep apnea (OSA).
Methods: This retrospective study included patients with OSA defined by an apnea-hypopnea index (AHI) of ≥ 5 and used the Insomnia Severity Index (ISI), the Epworth sleepiness scale, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7. Underestimation and overestimation of sleep state perception were defined as < 80% and > 120%, respectively, of the ratio between subjective and objective total sleep time.
Purpose: We investigated the moderating effect of sleep disturbance on the association between seizure recurrence and emotional instability in patients with epilepsy, independent of psychological distress.
Methods: This was a cross-sectional study. Patients completed the short form of the Affective Lability Scale (ALS-18), Insomnia Severity Index (ISI), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7).
Purpose: We investigated the long-term efficacy and safety of perampanel as a first add-on therapy in patients with focal epilepsy.
Methods: This retrospective study represented the 3-year extension phase of a multicenter, open-label, phase 4, prospective study of perampanel as a first add-on therapy in patients with focal epilepsy. Seizure and safety outcomes were assessed annually from the start of the extension study, and the retention rate was calculated from the start of perampanel exposure in the original study.
Difficulties obtaining private insurance reported by persons with epilepsy in Korea.
Epilepsy Behav
October 2021
Purpose: This study determined the proportion of persons with epilepsy (PWE) that possessed insurance policies and the difficulties they experienced in trying to obtain insurance in South Korea.
Methods: Persons with epilepsy and healthy control subjects were asked to complete a questionnaire in which they were asked if they had experienced problems obtaining four types of insurance, including life, medical indemnity, critical illness, and motor insurance. Insurance policies obtained before diagnosis of epilepsy were excluded in the analysis.
Background: We compared the prevalence of periodic leg movements during sleep (PLMS) according to two different scoring rules of the American Academy of Sleep Medicine (AASM) 2012 and World Association of Sleep Medicine (WASM) 2016 and determined their association with depressed mood in patients with obstructive sleep apnea (OSA).
Methods: PLMS, defined as a periodic leg movements index of >15, were diagnosed on a diagnostic and continuous positive airway pressure (CPAP) titration polysomnography using the AASM 2012 and WASM 2016 rules. The Beck Depression Inventory (BDI) and Epworth Sleepiness Scale (ESS) were used, and multiple regression analyses were performed.
Aim: Clinical implications for motor phenotypes of Parkinson's disease (PD) remain to be further elucidated, particularly at the early stages of the disease. We aimed to compare the non-motor and fall-related features between tremor-dominant (TD) and postural instability-gait difficulty (PIGD) subtypes in patients with early PD.
Methods: PD was categorized into TD, intermediate and PIGD types, according to the literature.
A Case Report of Wall-Eyed Bilateral Internuclear Ophthalmoplegia with Bilateral Facial Palsy.
J Stroke Cerebrovasc Dis
November 2020
Case reports of bilateral facial palsy with horizontal gaze restriction are rare. A 62-year-old woman experienced sudden onset of bilateral adduction deficits, bilateral abducting nystagmus accompanied with facial diplegia. We confirmed acute ischemic stroke in the midline dorsal pons, where medial longitudinal fasciculus (MLF) and facial nerve fascicles are located.

- * 268 patients were divided into groups based on their glycated hemoglobin (HbA1c) levels, with progressive motor deficits measured within 72 hours after the stroke.
- * Results show that higher HbA1c levels correspond to an increased incidence of progressive motor deficits, with a notable cutoff value of 6.65% being significant in predicting these deficits.
Background: Dopamine transporter (DAT) imaging may enable clinicians to discriminate idiopathic normal pressure hydrocephalus (iNPH) from other parkinsonian disorders. However, a specific pattern of dopaminergic loss in DAT imaging of iNPH patients remains to be further elucidated.
Methods: In this preliminary study, 11 patients with iNPH in our hospital between March 2017 and February 2019 were finally enrolled.
Objective: We aimed to identify risk factors for falls in patients with de novo Parkinson's disease (PD).
Methods: Forty-six patients with de novo PD were retrospectively included in the study. We assessed details on the patients' motor symptoms as well as non-motor symptoms using several representative scales for global cognition, depression, fatigue, and dysautonomia.
