Quantitative and qualitative evaluation of the hippocampal cytoarchitecture in adult cats with regard to the pathological diagnosis of hippocampal sclerosis.

PLoS One 2022 13;17(5):e0268010. Epub 2022 May 13.

Department of Veterinary Clinical Sciences, Small Animal Clinic, Justus-Liebig-University, Giessen, Hessen, Germany.

Cats are known to be affected by hippocampal sclerosis, potentially causing antiseizure drug(s) resistance. In order to lay the foundation for a standardized, systematic classification and diagnosis of this pathology in cats, this prospective study aimed at evaluating normal reference values of cellular densities and the cytoarchitecture of the feline hippocampus. Three transverse sections (head, body and tail) of each left hippocampus were obtained from 17 non-epileptic cats of different brachycephalic and mesocephalic breeds and age classes (range: 3-17 years).

SAPAP3 regulates epileptic seizures involving GluN2A in post-synaptic densities.

Cell Death Dis 2022 May 5;13(5):437. Epub 2022 May 5.

Department of Neurology, Chongqing Key Laboratory of Neurology, The First Affiliated Hospital of Chongqing Medical University, 1 Youyi Road, Chongqing, 400016, China.

Aberrantly synchronized neuronal discharges in the brain lead to epilepsy, a devastating neurological disease whose pathogenesis and mechanism are unclear. SAPAP3, a cytoskeletal protein expressed at high levels in the postsynaptic density (PSD) of excitatory synapses, has been well studied in the striatum, but the role of SAPAP3 in epilepsy remains elusive. In this study, we sought to investigate the molecular, cellular, electrophysiological and behavioral consequences of SAPAP3 perturbations in the mouse hippocampus. Read More

Drug-resistant focal epilepsy in children is associated with increased modal controllability of the whole brain and epileptogenic regions.

Commun Biol 2022 Apr 28;5(1):394. Epub 2022 Apr 28.

Department of Bioengineering, Electrical & Systems Engineering, Physics & Astronomy, Neurology, and Psychiatry, University of Pennsylvania, Philadelphia, PA, USA.

Network control theory provides a framework by which neurophysiological dynamics of the brain can be modelled as a function of the structural connectome constructed from diffusion MRI. Average controllability describes the ability of a region to drive the brain to easy-to-reach neurophysiological states whilst modal controllability describes the ability of a region to drive the brain to difficult-to-reach states. In this study, we identify increases in mean average and modal controllability in children with drug-resistant epilepsy compared to healthy controls. Read More

Comparative Efficacy and Safety of Lacosamide and Oxcarbazepine for Seizure Control in Children with Newly Diagnosed Solitary Neurocysticercosis.

J Trop Pediatr 2022 Apr;68(3)

Department of Radiodiagnosis and Imaging, All India Institute of Medical Sciences, Rishikesh 249203, India.

Background: In newly diagnosed neurocysticercosis (NCC) with seizures, the choice of anti-seizure medication (ASM) seems to be arbitrary due to a lack of comparative studies. Although oxcarbazepine (OXC) is often considered efficacious for focal seizures in NCC, due to adverse effects, newer ASMs like levetiracetam (LCM) and lacosamide are also being explored.

Methods: This study was performed by case record review of children with newly diagnosed solitary viable parenchymal NCC aged 4-18years who received lacosamide and OXC at least for 12 weeks between August 2019 and April 2021, from a prospective registry of a tertiary care teaching hospital in north India.

Chaotic and stochastic dynamics of epileptiform-like activities in sclerotic hippocampus resected from patients with pharmacoresistant epilepsy.

PLoS Comput Biol 2022 04 13;18(4):e1010027. Epub 2022 Apr 13.

Department of Neurology and Neurosurgery, Federal University of São Paulo (UNIFESP), São Paulo, São Paulo, Brazil.

The types of epileptiform activity occurring in the sclerotic hippocampus with highest incidence are interictal-like events (II) and periodic ictal spiking (PIS). These activities are classified according to their event rates, but it is still unclear if these rate differences are consequences of underlying physiological mechanisms. Identifying new and more specific information related to these two activities may bring insights to a better understanding about the epileptogenic process and new diagnosis. Read More
