Over the past decade, much progress has been made in dissecting apart the mechanisms underlying the anticonvulsant (and potentially, neuroprotective) effects of the KD (Gasior et al., 2006; Bough & Rho, 2007). The complex systemic and metabolic changes induced by a high-fat, low-carbohydrate diet – not surprisingly – provide fertile ground for very innovative and speculative hypotheses linking certain adaptations to a net anticonvulsant effect, ones that by necessity take researchers back to the earlier days of introductory biochemistry and human physiology. While many intriguing concepts and research data have been reviewed systematically in the context of the international symposium from which this supplement stems, the fundamental question of how the KD works remains as tantalizing as ever.

It is well known that an increase in the mitochondrial membrane potential (▵ψ) can promote mitochondrial reactive oxygen species (ROS) generation through increased electron shunting (Votyakova et al., 2001). Mitochondrial uncoupling proteins (UCPs) – which are activated by fatty acids – increase proton conductance and dissipate ▵ψ, thereby decreasing ROS formation (Mattson & Liu, 2003). Recent studies have implicated UCPs as potential mediators of a neuroprotective effect of the KD. Up-regulation of UCP2 expression in transgenic mice reduced seizure-induced neuronal cell death, and was associated with enhanced ATP levels and decreased ROS production (Diano et al., 2003). In normal rats, a high-fat suckling diet was protective against kainate-induced neuronal death in immature rat hippocampus, effects that were attributed to fatty acid-induced increases in UCP2 expression and reduction in ROS production (Sullivan et al., 2003). And finally, KD treatment in normal juvenile mice led to enhanced hippocampal expression and activity of all three known brain-localizable isoforms of UCP (i.e., UCP2, UCP4 and UCP5), and correlated with significant decreases in ROS levels (Sullivan et al., 2004).
While the relationships between seizure activity, oxidative stress and neuronal injury have yet to be clarified, previous studies have indicated that defects in antioxidant systems may contribute to seizure genesis and epileptogenesis (Cock, 2002; Patel, 2004; Liang & Patel, 2006; Shin et al, 2008). Earlier, the effects of a KD on mitochondrial ROS generation were discussed. Are there other mechanisms through which oxidative stress can be attenuated in epileptic brain?

The relevance of leptin to seizure susceptibility was recently highlighted by Erbayat-Altay and colleagues (2008) who demonstrated a significantly decreased threshold in leptin-deficient ob/ob mice to pentylenetetrazol-induced seizures. Indeed, leptin itself inhibits seizures induced by 4-aminopyridine and pentyelenetrazole-induced, possibly through blockade of AMPA receptor-mediated synaptic transmission (Xu et al., 2008). If the limiting of AMPA receptor-mediated transmission is a critical factor, it should be recalled this can also be accomplished by topiramate. With respect to the KD, the leptin signaling system is believed to contribute to slow weight gain associated with chronic treatment in both rodents and humans (Thio et al., 2006). KD-fed juvenile rodents had higher serum leptin levels and lower insulin levels than control rats fed a standard diet.
