Historically, many anticonvulsant medications have resulted from structural modifications of lead compounds that had themselves been discovered serendipitously. The mechanistic bases for their effectiveness have typically been elucidated post-hoc. At present, it is unclear which of many potential mechanisms reviewed in this supplement are relevant to the clinical effects of the KD. It would be far too difficult to integrate these numerous possibilities into a single unifying hypothesis (or a final common pathway), or to consider them simultaneously. Nevertheless, it might be instructive to consider each of these putative mechanisms one by one and ask a simple comparative question. If the mechanism or target in question is a critical determinant of the anticonvulsant efficacy of the KD, then would a similar intervention known to be based on that mechanism yield a comparable effect? Perhaps answering this question for each mechanistic speculation might help substantiate (or perhaps invalidate) that particular hypothesis.

The scientific rationale for elucidating mechanisms of disease pathogenesis or of therapeutic interventions has been traditionally based upon the lofty goal of discovering novel treatments, ones that would be more efficacious than existing options and also be devoid of side-effects altogether. Moreover, in epilepsy research, disease prevention or modification has become the “holy grail”, such that we are no longer complacent with symptomatic treatment and increasing attention is being given to understanding the processes of anti-epileptogenesis itself. Researchers in the field of the ketogenic diet (KD) have also embraced these tenets and recently embarked on that all-too-familiar Quixotic journey, with the ultimate aim of reducing the “difficult” KD regimen to a simple pill. If achieved, this result would represent an ironic recapitulation of the early history of the KD in the United States. Although the KD experienced an initial surge of interest following its introduction in the early 1920’s, it was relegated to near obscurity by the emergence of a familiar drug known as phenytoin. Henceforth, until the mid 1990’s, clinicians – for obvious practical reasons – found it simpler to prescribe a pill rather than an exacting diet.

Hal ini mempengaruhi asupan karbohidrat yang harus benar-benar dikurangi, dan menggantinya dengan lemak. Pengurangan karbohidrat menyebabkan tubuh Anda mengalami keadaan metabolisme yang disebut ketosis. Ketika hal itu terjadi, tubuh menjadi sangat efisien dalam membakar lemak sebagai energi. Hal ini juga membuat lemak menjadi keton (zat dari metabolisme lemak) di dalam hati, yang dapat menyediakan energi untuk otak.
One potential explanation for the anticonvulsant action of the KD argues that increased ATP synthesis should produce a positive bioenergetic balance, allowing stabilization of the resting membrane potential via enhanced activity of Na+-K+-ATPase (Bough & Rho, 2007). Several decades ago, De Vivo and colleagues (1978) reported that the KD increased the total quantity of bioenergetic substrates (such as adenosine triphosphate, or ATP) and elevated the energy charge in rat brain. These changes were purported to stabilize the cell membrane, especially in the face of excessive excitation. Consistent with these observations, a later human study utilizing magnetic resonance spectroscopic techniques indicated that patients with epilepsy fed a KD had elevated phosphocreatine to creatine levels in the brain (Pan et al., 1999). Recently, using cDNA microarray technology, increased expression of the mitochondrial ATP synthase β,D subunit in mouse brain was reported after KD treatment (Noh et al., 2004). And in the most comprehensive study of this kind to date, the KD was found to enhance mitochondrial biogenesis and significantly increase the number of transcripts encoding energy metabolism genes in rats (Bough et al., 2006). This increase in bioenergetic capacity enabled hippocampal slices from these animals to better withstand metabolic challenge from low glucose exposure. Taken together, the prevailing notion has been that increased energy production and reserve capacity enable greater resistance to neuronal hyperexcitability and hypersynchrony.
