RESUMO
Progressive myoclonic epilepsies (PMEs) are a group of rare genetic diseases. Common clinical manifestations include action myoclonus often with generalized tonic-clonic seizures, cognitive impairment and other focal neurological deficits. PMEs generally respond poorly to antiseizure drugs and have a poor overall prognosis. Disorders that can cause PMEs include Unverricht-Lundborg disease, Lafora disease, neuronal ceroid lipofuscinosis, myoclonic epilepsy with fragmented red fiber syndrome, sialic acidosis, dentate erythronucleus pallidus Lewy body atrophy, etc. The current treatments for PMEs include drug therapy, neuromodulatory therapy, dietary therapy, anti-inflammatory and immunomodulatory therapy, enzyme replacement therapy and gene therapy. This article reviews the currently known treatments for PMEs, and provides ideas for better research and exploration of treatments for PMEs.
RESUMO
Patients with dentatorubral-pallidoluysian atrophy occasionally elicit psychosis. So far, one study reported first generation antipsychotics drugs may provide an effective treatment; however, there is no literature on the benefits of second generation antipsychotics. We report on a 44-year-old man with dentatorubral-pallidoluysian atrophy whose psychotic symptoms were effectively treated with olanzapine. Our observation suggests some second generation antipsychotics provide a therapeutic option for ameliorating psychosis in dentatorubral-pallidoluysian atrophy.
