OBJECTIVE: To analyze the attitude and results of Italian epilepsy surgery centers in the surgical management of "low grade epilepsy associated neuroepithelial tumors" (LEATs). METHODS: We conducted a retrospective study enrolling 339 consecutive patients with LEATs who underwent surgery between January 2009 and June 2015 at eight Italian epilepsy surgery centers. We compared demographic, clinical, pathologic, and surgical features of patients with favorable (Engel class I) and unfavorable (Engel class II, III, and IV) seizure outcome...

OBJECTIVE: Nocturnal frontal lobe epilepsy (NFLE) is an idiopathic partial epilepsy with a family history in about 25% of cases, with autosomal dominant inheritance (autosomal dominant NFLE [ADNFLE]). Traditional antiepileptic drugs are effective in about 55% of patients, whereas the rest remains refractory. One of the key pathogenetic mechanisms is a gain of function of neuronal nicotinic acetylcholine receptors (nAChRs) containing the mutated α4 or β2 subunits. Fenofibrate, a common lipid-regulating drug, is an agonist at peroxisome proliferator-activated receptor alpha (PPARα) that is a ligand-activated transcription factor, which negatively modulates the function of β2-containing nAChR...

OBJECTIVE Temporal lobe epilepsy (TLE) is the most common type of pharmacoresistant focal epilepsy, for which anterior mesial temporal lobe resection (AMTLR) is a treatment option. Focal cortical dysplasia Type IIIa (FCD IIIa), a developmental lesion resulting from defects in neuronal formation and migration into the temporal pole (FCD I) combined with hippocampal sclerosis (HS), can be a neuropathological finding. In this study, the authors investigate the impact of FCD IIIa on seizure outcome in patients with TLE who underwent AMTLR...

In the absence of a culprit epileptogenic lesion, pharmacoresistant seizures should prompt the physician to consider potentially treatable metabolic epilepsies, especially in the presence of developmental delays. Even though the anti-seizure treatment of the epilepsies remains symptomatic and usually tailored to an electroclinical phenotype rather than to an underlying etiology, a thorough metabolic workup might reveal a disease with an etiology-specific treatment. Early diagnosis is essential in the case of treatable metabolic epilepsies allowing timely intervention...

OBJECTIVE: Evaluation for surgical treatment is offered to patients who do not respond to antiepileptic drugs. Pseudo-pharmacoresistance (PPR) has been described in the context of impaired compliance, incorrect diagnosis of epilepsy or pharmacological interference resulting in too low blood levels. We were interested to determine the frequency and causes of PPR in patients admitted for presurgical evaluation. METHODS: We reviewed 553 drug levels in 199 patients and analyzed the relative frequency of drugs below reference range (10 and 20% below the range)...

REVIEW
Fei Tang, Anika M S Hartz, Björn Bauer
Epilepsy is a common neurological disorder that affects over 70 million people worldwide. Despite the recent introduction of new antiseizure drugs (ASDs), about one-third of patients with epilepsy have seizures refractory to pharmacotherapy. Early identification of patients who will become refractory to ASDs could help direct such patients to appropriate non-pharmacological treatment, but the complexity in the temporal patterns of epilepsy could make such identification difficult. The target hypothesis and transporter hypothesis are the most cited theories trying to explain refractory epilepsy, but neither theory alone fully explains the neurobiological basis of pharmacoresistance...

SYNGAP1 gene mutation has been associated with epilepsy which is often drug resistant, with seizure types including eyelid myoclonia. However, detailed descriptions, including ictal video-EEG, have not been reported. We report the case of a 4-year-old boy who developed recurrent epileptic eyelid twitching at 1 year and 5 months of age. Seizures gradually increased in frequency to more than 50 times per day and manifested with upward eye deviation, motion arrest, loss of consciousness, and eyelid twitching lasting for five seconds...

OBJECTIVE: The medium-chain triglyceride (MCT) ketogenic diet contains both octanoic (C8) and decanoic (C10) acids. The diet is an effective treatment for pharmacoresistant epilepsy. Although the exact mechanism for its efficacy is not known, it is emerging that C10, but not C8, interacts with targets that can explain antiseizure effects, for example, peroxisome proliferator-activated receptor-γ (eliciting mitochondrial biogenesis and increased antioxidant status) and the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor...

Animal models have provided a wealth of information on mechanisms of epileptogenesis and comorbidogenesis, and have significantly advanced our ability to investigate the potential of new therapies. Processes implicating brain inflammation have been increasingly observed in epilepsy research. Herein we discuss the progress on animal models of epilepsy and comorbidities that inform us on the potential role of inflammation in epileptogenesis and comorbidity pathogenesis in rodent models of West syndrome and the Theiler's murine encephalomyelitis virus (TMEV) mouse model of viral encephalitis-induced epilepsy...

The risk of unprovoked seizures in population-based cohorts of cerebral infection survivors is 7-8% in developed countries, rising to considerably higher rates in resource-poor countries. The main risk factors for epilepsy after cerebral infection, besides acute seizures, are infection-associated brain lesions and status epilepticus during the acute phase. Despite the high prevalence of pharmacoresistant epilepsies after cerebral infections, especially in patients with MRI-identifiable lesions, only a small minority undergoes epilepsy surgery...

Since the middle of the 19th century, both neurologists and psychiatrists have linked psychosis and epilepsy. Clozapine, the most effective antipsychotic drug, alters electroencephalographic activity and carries a significant risk of causing seizures. Unfortunately, this risk limits the drug's potential use in treating pharmacoresistant psychosis in patients with epilepsy. We present a unique case in which we used clozapine successfully as a last resort treatment for chronic interictal psychosis in a 43-year-old woman with severe pharmacoresistant epilepsy and recurrent status epilepticus...

Considering the potential of flavonoids in reversing the P-glycoprotein (P-gp)-mediated multidrug resistance, this work aimed to assess the combined effects of silymarin and (-)-epigallocatechin gallate (EPG) on the pharmacokinetics of the P-gp substrates oxcarbazepine (OXC) and licarbazepine (LIC). Rats were pre-treated intraperitoneally with silymarin (25 mg/kg), EPG (25 mg/kg), silymarin/EPG (12.5/12.5 mg/kg; 6.25/18.75 mg/kg; 18.75/6.25 mg/kg) or verapamil (25 mg/kg, reference P-gp inhibitor) before the intraperitoneal administration of OXC (50 mg/kg)...

This review aims to synthesize all the available data on brain molecular imaging, such as single-photon emission computed tomography (SPECT) and interictal fluorodeoxyglucose positron emission tomography (FDG-PET), in focal epilepsies. SPECT imaging is able to measure regional cerebral blood flow and its major innovation remains its ictal imaging value. On the other hand, FDG-PET, which has higher spatial resolution and lower background activity than SPECT, enables glycolytic metabolism to be identified in interictal states...

Pituitary macroadenoma constitutes a frequently misdiagnosed benign tumor. We report herein a case where such macroadenoma, a prolactinoma, was incidentally discovered in a 63-year-old man who had been referred to F-FDG PET and F-FDOPA PET imaging for a pharmacoresistant epilepsy. An increased uptake was documented for both radiotracers within the sellar region, although with a much higher contrast for F-FDOPA than for F-FDG. This case presents an increased uptake documented within a prolactinoma owing to the high contrast and image quality provided by F-FDOPA PET...

De novo mutations are a frequent cause of disorders related to brain development. We report the results from the screening of two patients diagnosed with intellectual disability (ID) using exome sequencing to identify new causative de novo mutations. Exome sequencing was conducted in two patient-parent trios to identify de novo variants. In silico and expression studies were also performed to evaluate the functional consequences of these variants. The two patients presented developmental delay with minor facial dysmorphy...
