James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

Evgenia Gurevich, Daniel Landau
Hypophosphatasia is the inborn error of metabolism that is characterized by low serum alkaline-phosphatase activity, due to loss-of-function mutations within the gene for tissuenonspecific isoenzyme of alkaline phosphatase [TNSALP]. The manifestations of hypophosphatasia range from neonatal death with almost no skeletal mineralization to dental problems in adults without any bone symptoms. There are no case reports of infantile hypophosphatasia in Israel. The existence of enzymatic replacement treatment for this disease makes it important to diagnose this problem as soon as possible...

A 50-year old male suffered new-onset clinical and subclinical seizures provoked by acute bilateral embolic strokes in the parietal and occipital regions as a complication of aortic valve replacement surgery. After successful treatment of these refractory symptomatic seizures with intravenous propofol and antiseizure medications, video-EEG recordings revealed acute and transient fixation-off sensitivity or scotosensitivity that resolved within 10 weeks.

BACKGROUND/AIM: The safety of amateur and professional boxing is a contentious issue. We hypothesised that advanced magnetic resonance imaging and neuropsychological testing could provide evidence of acute and early brain injury in amateur boxers. METHODS: We recruited 30 participants from a university amateur boxing club in a prospective cohort study. Magnetic resonance imaging (MRI) and neuropsychological testing was performed at three time points: prior to starting training; within 48 h following a first major competition to detect acute brain injury; and one year follow-up...

Accumulating evidence supports that activation of inflammatory pathways is a crucial factor contributing to the pathogenesis of seizures. In particular, the activation of interleukin-1 beta (IL-1β) system exerts proconvulsant effects in a large variety of seizure models. Myeloid differentiation factor 88 (MyD88) is a critical adaptor protein in the signaling cascade elicited by IL-1β. The present study aimed to investigate the expression pattern of MyD88 in rat models of seizures and in patients with refractory temporal lobe epilepsy (TLE), and to study the role of MyD88 in epileptic seizures...

Sulfite accumulates in tissues of patients affected by sulfite oxidase (SO) deficiency, a neurometabolic disease characterized by seizures and progressive encephalopathy, often resulting in early death. We investigated the effects of sulfite on mitochondrial function, antioxidant system, glial reactivity and neuronal damage in rat striatum, as well as the potential protective effects of bezafibrate on sulfite-induced toxicity. Thirty-day-old rats were intrastriatally administered with sulfite (2μmol) or NaCl (2μmol; control) and euthanized 30min after injection for evaluation of biochemical parameters and western blotting, or 7days after injection for analysis of glial reactivity and neuronal damage...

Lennox-Gastaut syndrome (LGS) is commonly characterized by a triad of features including multiple seizure types, intellectual disability or regression. LGS type of seizures is epilepsy which is due to abnormal vibrations occurring in seizures. During the time of such abnormal vibrations, both the seizures and the lungs suffer a lack in oxygen content to a considerable extent. This results in prolonged vibrations and loses of nervous control. As a neuro-lung protective strategy, a novel attempt has been made to enrich both seizures and lungs with oxygen content through the support of Perfluorodecalin (an excellent oxygen carrier) C10F18 (PFD) and Perfluorohexane C6F14 (PFH) along with an enhancement in the antiepileptic activity by the two chosen antiepileptic drugs (AEDs) Carbamazepine (CBZ) and Benzodiazepine (BDZ)...

The inhibitory restraint necessary to suppress aberrant activity can fail when inhibitory neurons cease to generate action potentials as they enter depolarization block. We investigate possible bifurcation structures that arise at the onset of seizure-like activity resulting from depolarization block in inhibitory neurons. Networks of conductance-based excitatory and inhibitory neurons are simulated to characterize different types of transitions to the seizure state, and a mean field model is developed to verify the generality of the observed phenomena of excitatory-inhibitory dynamics...

Oxcarbazepine is indicated for the treatment of partial or generalized tonic-clonic seizures. The majority of the oxcarbazepine is converted into its active metabolite, 10-hydroxycarbazepine (MHD), which can exist as R-(-)- and S-(+)-MHD enantiomers. Here we describe the influence of the P-glycoprotein (P-gp) inhibitor verapamil, on the disposition of oxcarbazepine and MHD enantiomers, both of which are P-gp substrates. Healthy subjects (n=12) were randomized to oxcarbazepine or oxcarbazepine combined with verapamil at doses of 300mg b...

PURPOSE: Status Epilepticus (SE) is a common medical emergency carrying a high morbidity and mortality. Levetiracetam (LEV) is a novel anticonvulsant effective against varied seizures. Few prospective studies have addressed its use in SE. We aimed to examine the efficacy of intravenous LEV in controlling SE and cluster attacks of seizures (CS), in comparison with IV phenytoin (DPH), using a prospective, randomized study design. METHOD: Adult patients with SE or CS, following an initial dose of IV benzodiazepine to control ongoing seizure, were randomized to receive either medication...

Anti-N-methyl-D-aspartate receptor encephalitis is a neurological syndrome that is more common in young women and is often associated with ovarian teratoma. It is characterized by acute general unspecific symptoms that evolve to neurological deterioration, psychosis and seizures. In its more advanced stage it is associated with abnormal movements and dysautonomia.We report two cases in women of 23 and 12 years of age. Given its low incidence, we present the clinical exercise that led to their diagnoses and the treatment options employed...

Seizures occur at a higher frequency in people with Alzheimer's disease (AD) but overt, clinically obvious events are infrequent. Evidence from animal models and studies in mild cognitive impairment suggest that subclinical epileptic discharges may play a role in the clinical and pathophysiological manifestations of AD. In this feasibility study, the neurophysiological and cognitive effects of acute administration of levetiracetam (LEV) are measured in patients with mild AD to test whether it could have a therapeutic benefit...
