OBJECTIVES: Loss of consciousness may be due to neurological or cardiac involvement in mitochondrial disease, and is often difficult to attribute to either cause, as in the following case.
CASE REPORT: A 67-year-old man with hypertension, diabetes, elevated serum creatine kinase, glaucoma, optic atrophy, and vertigo had experienced recurrent losses of consciousness since 63 years of age. Diagnostic work-up revealed paroxysmal supraventricular arrhythmias, hyperlipidemia, steatosis hepatis, renal insufficiency, polyneuropathy, first-degree atrio-ventricular block, orthostasis, and cataract. From the age of 66 years, he developed tonic-clonic seizures. Electrocardiography loop recording showed some losses of consciousness as associated with supraventricular tachycardias and others with epileptic activity or arterial hypotension. Neurological investigations and muscle biopsy were indicative of mitochondrial disease with multisystem involvement. Losses of consciousness disappeared after catheter ablation and treatment with levetiracetam.
CONCLUSION: Recurrent loss of consciousness in mitochondrial disease may not only be due to arrhythmias but also seizure activity, or autonomic neuropathy. Arrhythmias, seizures, and polyneuropathy may have a common underlying cause affecting various tissues.
