Abstract:

Abstract Lately , there have been a few studies warning about an increased risk of sudden death in patients with Parkinson's disease . We report two men with Parkinson's disease with a disease duration of more than ten years . In the first case , the subject was treated with L - dopa/carbidopa/entacapone , rasagiline , and amantadine . The second subject was treated with L - dopa/carbidopa , piribedil , and amantadine ( in this case we had to perform an autopsy ) . We discuss the causes of this phenomenon : sympathetic cardioselective neuronal degeneration , parasympathetic dysautonomia , and QTc interval prolongation by antiparkinsonian drugs . Practical approaches are suggested for monitoring this group of patients until more data about the origin of this phenomenon is available .
