Landau-Kleffner syndrome is characterized by epileptic aphasia associated with electrical status epilepticus of slow wave sleep. A 5-year-old female, who had manifested normal developmental progress, was referred with principal complaints of fluctuating sensory aphasia and bizarre behavior during the preceding 4 months. Landau-Kleffner syndrome was confirmed by clinical and electroencephalographic features; in addition, the patient's mitochondrial respiratory chain-complex I deficiency was confirmed by fibroblast culture with the evidence of energy metabolism disorder. This patient's seizures were intractable to many antiepileptic drugs, adrenocorticotrophic hormone, and intravenous immunoglobulin, with catastrophic cognitive and behavioral decline, but the seizures were successfully controlled by ketogenic diet with supplementary mitochondrial cocktail including coenzyme Q10, riboflavin, L-carnitine, and high-dose multivitamins. The patient finally regained fully normal cognitive functioning. Landau-Kleffner syndrome with mitochondrial respiratory chain-complex I deficiency was controlled in this case by ketogenic diet and supplementary mitochondrial cocktail therapy.

Temporal lobe epilepsy (TLE) is the most common form of epilepsy in adults and the most resistant type to treatment. Novel treatment approaches are strongly required to prevent or even reverse the cellular and molecular mechanisms of epileptogenesis. In this study, we investigated the possible neuroprotective effect of coenzyme Q10 (CoQ10) in an intrahippocampal kainate model of TLE in rat. Kainate injection caused a higher seizure severity during status epilepticus and spontaneous seizure phases, and CoQ10 pretreatment significantly attenuated its severity and incidence rate. Intrahippocampal kainate also led to elevation of malondialdehyde (MDA) and nitrite, and CoQ10 significantly attenuated the increased MDA and nitrite content. In addition, intrahippocampal kainate induced a significant degeneration of neurons in CA1, CA3, and hilar regions of the hippocampus, and CoQ10 significantly attenuated these changes in CA1 and CA3 regions. Timm's staining data showed a robust mossy fiber sprouting (MFS) in dentate gyrus of kainate-lesioned rats and CoQ10 significantly lowered MFS intensity. These data suggest that CoQ10 pretreatment could attenuate spontaneous recurrent seizures and inhibit hippocampal neuronal loss and aberrant MFS in kainate-induced model of TLE in rat, and part of its beneficial effect is due to its potential to mitigate oxidative stress.

We studied the efficacy of drugs indicated for mitochondrial dysfunction in the treatment of 21 patients with acute encephalopathy with onset of febrile convulsive status epilepticus at our hospital from January 2006 to December 2014. Among them, 11 patients had been treated with a mitochondrial drug cocktail consisting of vitamin B1, vitamin C, biotin, vitamin E, coenzyme Q10, and l-carnitine (prescription group) and 10 patients were not treated with the cocktail (non-prescription group). We retrospectively reviewed age, trigger, clinical form, treatment start time, and sequelae. Clinical form was classified into a biphasic group presenting acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and a monophasic group. Sequelae were classified as (A) no sequelae group or (B) sequelae group, and differences in the interval between diagnosis and treatment were also evaluated. The sequelae were not different between the mitochondrial drug cocktail prescription and non-prescription groups, but significantly better in the group administered the mitochondrial drug cocktail within 24h (P=0.035). We expect that early treatment with a mitochondrial drug cocktail could prevent sequelae in acute encephalopathy with onset of febrile convulsive status epilepticus.
