To analyze seizure-like motor phenomena immediately occurring after concussion (concussive convulsions).

Twenty-five videos of concussive convulsions were obtained from YouTube as a result of numerous sports-related search terms. The videos were analyzed by four independent observers, documenting observations of the casualty, the head injury, motor symptoms of the concussive convulsions, the postictal period, and the outcome.

Immediate responses included the fencing response, bear hug position, and bilateral leg extension. Fencing response was the most common. The side ...

This study attempted to validate the effects of neonatal estradiol in ameliorating the spasms in the prenatally betamethasone-primed N-methyl-d-aspartate (NMDA) model of infantile spasms in rats as shown previously in a mouse Arx gene knock-in expansion model of infantile spasms.

Neonatal rats prenatally exposed to betamethasone (on day 15 of pregnancy) were treated with subcutaneous 40 ng/g estradiol benzoate (EB) between postnatal days (P)3–P10 or P0–P5. A synthetic estrogen analogue, diethylstilbestrol, was used between P0 and P5 ...

To estimate long-term socioeconomic consequences and health care costs of epilepsy with onset in childhood and adolescence.

A historical prospective cohort study of Danish individuals with epilepsy, age up to 20 years at time of diagnosis between January 1981 and December 2012. Information about marital status, parenthood, educational level, employment status, income, use of the health care system, and cost of medicine was obtained from nationwide administrative and health registers.

We identified 12,756 and 28,319 people with diagnosed ...

There is scant evidence to guide the management of infantile spasms after successful response to initial therapies. There is significant risk of relapse, largely because effective pharmacologic treatments cannot be continued long term because of concern for significant adverse events. Zonisamide (ZNS) and topiramate (TPM) are commonly used to prevent relapse, and the purpose of this study was to specifically evaluate the efficacy of ZNS and TPM as agents for secondary prevention of infantile spasms.

Patients with ...

The aim of our study was to investigate the neuronal networks underlying background oscillations of epileptic encephalopathy with continuous spikes and waves during slow sleep (CSWS).

Sleep electroencephalography (EEG) studies before and after the treatment were investigated in 15 patients with CSWS. To investigate functional and effective connectivity within the network generating the delta activity in the background sleep EEG, the methods of dynamic imaging of coherent sources (DICS) and renormalized partial directed coherence (RPDC) were applied.

The DBA/1 mouse is a relevant animal model of sudden unexpected death in epilepsy (SUDEP), as it exhibits seizure-induced respiratory arrest (S-IRA) evoked by acoustic stimulation, followed by cardiac arrhythmia and death. Defects in serotonergic neurotransmission may contribute to S-IRA. The tryptophan hydroxylase-2 (TPH2) enzyme converts L-tryptophan to 5-hydroxytryptophan (5-HTP), a precursor for central nervous system (CNS) serotonin (5-HT) synthesis; and DBA/1 mice have a polymorphism that decreases TPH2 activity. We, therefore, hypothesized that supplementation with 5-HTP ...
