Neuparth-Sottomayor, Mariana; Morais, Tatiana P.; Good, Mark; Sebastião, Ana M; Di Giovanni, Giuseppe; Crunelli, Vincenzo; Vaz, Sandra H.Epidemiological studies reveal gender-specific differences in epilepsy. Childhood absence epilepsy (CAE), which is more prevalent in females, is characterized by typical absence seizures (ASs) consisting of brief periods of unconsciousness, associated with 2.5-4 Hz spike-wave discharges (SWDs) in the electroencephalogram (EEG). Children with CAE often present neuropsychological comorbidities, including deficits...
Cognitive comorbidities of experimental absence seizures are independent of anx...
Neuparth-Sottomayor, Mariana; Pina, Carolina; Morais, Tatiana P.; Farinha Ferreira, Jorge Miguel; Abreu, Daniela Sofia; Solano, Filipa; Mouro, FranciscoTypical absence seizures (ASs) are brief periods of lack of consciousness, associated with 2.5-4 Hz spike-wave discharges (SWDs) in the EEG, which are highly prevalent in children and teenagers. The majority of probands in these young epileptic cohorts show neuropsychological comorbidities, including cognitive, memory and mood impairments, even after the seizures are pharmacologically controlled. Similar cognit...
Going the extra (synaptic) mile: excitotoxicity as the road toward neurodegener...
Armada-Moreira, Adam; Gomes, Joana I.; Pina, Carolina Campos; Savchak, Oksana K.; Gonçalves-Ribeiro, Joana; Rei, Nádia; Pinto, Sara; Morais, Tatiana P.Excitotoxicity is a phenomenon that describes the toxic actions of excitatory neurotransmitters, primarily glutamate, where the exacerbated or prolonged activation of glutamate receptors starts a cascade of neurotoxicity that ultimately leads to the loss of neuronal function and cell death. In this process, the shift between normal physiological function and excitotoxicity is largely controlled by astrocytes si...
