TL;DR: A revised definition of epilepsy brings the term in concordance with common use for individuals who either had an age‐dependent epilepsy syndrome but are now past the applicable age or who have remained seizure‐free for the last 10 years and off antiseizure medicines for at least the last 5 years.
Abstract: Epilepsy was defined conceptually in 2005 as a disorder of the brain characterized by an enduring predisposition to generate epileptic seizures. This definition is usually practically applied as having two unprovoked seizures >24 h apart. The International League Against Epilepsy (ILAE) accepted recommendations of a task force altering the practical definition for special circumstances that do not meet the two unprovoked seizures criteria. The task force proposed that epilepsy be considered to be a disease of the brain defined by any of the following conditions: (1) At least two unprovoked (or reflex) seizures occurring >24 h apart; (2) one unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after two unprovoked seizures, occurring over the next 10 years; (3) diagnosis of an epilepsy syndrome. Epilepsy is considered to be resolved for individuals who either had an age-dependent epilepsy syndrome but are now past the applicable age or who have remained seizure-free for the last 10 years and off antiseizure medicines for at least the last 5 years. "Resolved" is not necessarily identical to the conventional view of "remission or "cure." Different practical definitions may be formed and used for various specific purposes. This revised definition of epilepsy brings the term in concordance with common use. A PowerPoint slide summarizing this article is available for download in the Supporting Information section here.

TL;DR: Edaravone represents a neuroprotective agent which is potentially useful for treating acute ischemic stroke, since it can exert significant effects on functional outcome as compared with placebo.
Abstract: Edaravone, a novel free radical scavenger, demonstrates neuroprotective effects by inhibiting vascular endothelial cell injury and ameliorating neuronal damage in ischemic brain models. The present study was undertaken to verify its therapeutic efficacy following acute ischemic stroke. We performed a multicenter, randomized, placebo-controlled, double-blind study on acute ischemic stroke patients commencing within 72 h of onset. Edaravone was infused at a dose of 30 mg, twice a day, for 14 days. At discharge within 3 months or at 3 months after onset, the functional outcome was evaluated using the modified Rankin Scale. Two hundred and fifty-two patients were initially enrolled. Of these, 125 were allocated to the edaravone group and 125 to the placebo group for analysis. Two patients were excluded because of subarachnoid hemorrhage and disseminated intravascular coagulation. A significant improvement in functional outcome was observed in the edaravone group as evaluated by the modified Rankin Scale (p = 0.0382). Edaravone represents a neuroprotective agent which is potentially useful for treating acute ischemic stroke, since it can exert significant effects on functional outcome as compared with placebo.

TL;DR: Prx II deficiency results in increased production of H2O2, enhanced activation of PDGF receptor (PDGFR) and phospholipase Cγ1, and subsequently increased cell proliferation and migration in response to PDGF, demonstrating a localized role for endogenous H2 O2 in PDGF signalling, and indicating a biological function of Prx II in cardiovascular disease.
Abstract: Platelet-derived growth factor (PDGF) is a potent mitogenic and migratory factor that regulates the tyrosine phosphorylation of a variety of signalling proteins via intracellular production of H2O2 (refs 1, 2-3). Mammalian 2-Cys peroxiredoxin type II (Prx II; gene symbol Prdx2) is a cellular peroxidase that eliminates endogenous H2O2 produced in response to growth factors such as PDGF and epidermal growth factor; however, its involvement in growth factor signalling is largely unknown. Here we show that Prx II is a negative regulator of PDGF signalling. Prx II deficiency results in increased production of H2O2, enhanced activation of PDGF receptor (PDGFR) and phospholipase Cgamma1, and subsequently increased cell proliferation and migration in response to PDGF. These responses are suppressed by expression of wild-type Prx II, but not an inactive mutant. Notably, Prx II is recruited to PDGFR upon PDGF stimulation, and suppresses protein tyrosine phosphatase inactivation. Prx II also leads to the suppression of PDGFR activation in primary culture and a murine restenosis model, including PDGF-dependent neointimal thickening of vascular smooth muscle cells. These results demonstrate a localized role for endogenous H2O2 in PDGF signalling, and indicate a biological function of Prx II in cardiovascular disease.

TL;DR: The distribution of stroke subtypes in the YSR was largely comparable with that of western registries, and the highest incidence of UD might be related to the strict application of TOAST criteria.
Abstract: Background and Purpose: The hospital-based stroke registry is a well-established method useful for understanding diverse clinical characteristics of stroke related to geographical,

TL;DR: Episodes of discrimination, coping strategies, and personality may be important in feeling the stigma of epilepsy, and these findings may provide a basis for further studies to clarify the causative factors generating the stigma.
Abstract: Summary Purpose: To evaluate the factors, including personality and coping styles, likely to be influential in enhancing the social stigma of epilepsy. Methods: Data were collected from 400 adults with epilepsy recruited from 10 epilepsy centers in Korea. Clinical information about seizures was obtained by neurologists, and other information was collected from self-completed questionnaires, including those measuring stigma scales. Results: Thirty-one percent of people with epilepsy felt stigmatized by their condition and in 9% of these the stigma was severe. Multivariate analysis identified experiences of actual discrimination from society, introverted personality, problem solving controllability, and emotional subscale of QOLIE-31 as being independently associated with the social stigma of epilepsy. Conclusions: Episodes of discrimination, coping strategies, and personality may be important in feeling the stigma of epilepsy. These findings may provide a basis for further studies to clarify the causative factors generating the stigma of epilepsy.

TL;DR: These guidelines supersede the prior 2007 guidelines and 2009 updates and support the overarching concept of stroke systems of care and detail aspects of stroke care from patient recognition; emergency medical services activation, transport, and triage; through the initial hours in the emergency department and stroke unit.
Abstract: Background and Purpose—The authors present an overview of the current evidence and management recommendations for evaluation and treatment of adults with acute ischemic stroke. The intended audienc...
