Sporadic Leigh syndrome – http://id.who.int/icd/entity/706425213

Leigh syndrome is a progressive neurological disease defined by specific neuropathological features associating brainstem and basal ganglia lesions. Loss of motor milestones, hypotonia with poor head control, recurrent vomiting, and a movement disorder are common initial symptoms. Pyramidal and extrapyramidal signs, nystagmus, breathing disorders, ophthalmoplegia and peripheral neuropathy are often noted later. Epilepsy is relatively uncommon. Leigh syndrome has multiple causes, all of which imply a defect in aerobic energy production, ranging from the pyruvate dehydrogenase complex to the oxidative phosphorylation pathway. The sporadic Leigh syndrome occurs in single and scattered cases, without apparent family history.
