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.

Epilepsy is a severe neurological disorder characterized by altered electrical activity in the brain. Important pathophysiological mechanisms include disturbed metabolism and homeostasis of major excitatory and inhibitory neurotransmitters, glutamate and GABA. Current drug treatments are largely aimed at decreasing neuronal excitability and thereby preventing the occurrence of seizures. However, many patients are refractory to treatment and side effects are frequent. Temporal lobe epilepsy (TLE) is the most common type of drug-resistant epilepsy in adults. In rodents, the pilocarpine-status epilepticus model reflects the pathology and chronic spontaneous seizures of TLE and the pentylenetetrazole kindling model exhibits chronic induced limbic seizures. Accumulating evidence from studies on TLE points to alterations in astrocytes and neurons as key metabolic changes. The present review describes interventions which alleviate these disturbances in astrocyte-neuronal interactions by supporting mitochondrial metabolism. The compounds discussed are the endogenous transport molecule acetyl-L-carnitine and the triglyceride of heptanoate, triheptanoin. Both provide acetyl moieties for oxidation in the tricarboxylic acid cycle whereas heptanoate is also provides propionyl-CoA, which after carboxylation can produce succinyl-CoA, resulting in anaplerosis-the refilling of the tricarboxylic acid cycle.

A one-year-old girl visited the hospital due to limb torsion and developmental regression for one month after hand, foot and mouth disease. At the age of 11 months, she visited a local hospital due to fever for 5 days and skin rash with frequent convulsions for 2 days and was diagnosed with severe hand, foot and mouth disease, viral encephalitis, and status epilepticus. Brain MRI revealed symmetric abnormal signals in the bilateral basal ganglia, bilateral thalamus, cerebral peduncle, bilateral cortex, and hippocampus. She was given immunoglobulin, antiviral drugs, and anticonvulsant drugs for 2 weeks, and the effect was poor. Blood and urine screening for inherited metabolic diseases were performed to clarify the etiology. The analysis of urine organic acids showed significant increases in glutaric acid and 3-hydroxyglutaric acid, which suggested glutaric aciduria type 1, but her blood glutarylcarnitine was normal, and free carnitine significantly decreased. After the treatment with low-lysine diets, L-carnitine, and baclofen for 1 month, the patient showed a significant improvement in symptoms. Hand, foot and mouth disease is a common viral infectious disease in children, and children with underlying diseases such as inherited metabolic diseases and immunodeficiency may experience serious complications. For children with hand, foot and mouth disease and unexplained encephalopathy, inherited metabolic diseases should be considered.
