Fundamental mechanisms of seizure generation are largely unknown. Excessivedepolarization may be the result of the following phenomena:
- Disturbances in energy production, which can result in a degradation in sodium-potassium pump (Na-K). Hypoxemia, hypoglycemia, ischemia can cause disturbancesin energy production.
- Alteration of neuronal membrane may lead to increased permeability to sodium (Na);
- Excess neurotransmitters stimulants to those inhibitors can produce excessivedepolarization of neuronal membrane;
Seizures in newborns differ from high child and newborn nscutii seizures differ frompremature to term.
Newborns rarely have generalized tonic-clonic seizures, well organized and haveconvulsions premature less organized. These issues are due to the neuroanatomy and neuro-development status in the neonatal period.
Children who manifest a seizure notice a immature anatomical axonal and dendriticbranches are developing synaptic connections incomplete myelination deficiency incortical efferent systems, excessive neuronal growth.
Physiological immaturity notice a neurophysiological deficit due mielinizarii efferentneural formations, as subtle seizures, without correspondence in theelectroencephalogram (EEG) and generalized seizures is low.
