Mitochondrial oxidative stress and dysfunction are contributing factors to various neurological disorders. Recently, there has been increasing evidence supporting the association between mitochondrial oxidative stress and epilepsy. Although certain inherited epilepsies are associated with mitochondrial dysfunction, little is known about its role in acquired epilepsies such as temporal lobe epilepsy (TLE). ⋯ Mitochondria are the primary site of reactive oxygen species (ROS) production making them uniquely vulnerable to oxidative stress and damage which can further affect cellular macromolecule function, the ability of the electron transport chain to produce ATP, antioxidant defenses, mitochondrial DNA stability, and synaptic glutamate homeostasis. Oxidative damage to one or more of these cellular targets may affect neuronal excitability and increase seizure susceptibility. The specific targeting of mitochondrial oxidative stress, dysfunction, and bioenergetics with pharmacological and non-pharmacological treatments may be a novel avenue for attenuating epileptogenesis.

Use of medication with a desired effect on the central nervous system (as with anti-epileptic drugs) in children will undoubtedly cause concern about neurodevelopment. Data are emerging to suggest an effect of anticonvulsants on the developing brain of the unborn child when administered to mothers with epilepsy. ⋯ Although data are available with regard to some anti-epileptic drugs (AEDs) they remain lacking particularly in the very young with regard to efficacy as well as neurodevelopmental effects of the newer anti-epileptic drugs. Ongoing evaluation is required to ensure the best clinical practice in each individual.
