Parkinsonism-hyperpyrexia, a rare consequence of deep brain stimulator malfunction in advanced Parkinson’s disease

Abstract

Parkinsonism-hyperpyrexia syndrome (PHS) is a rare neurological emergency that shares clinical features with neuroleptic malignant syndrome. It is usually due to sudden deprivation of dopaminergic treatment, although there are cases related to failure of the deep brain stimulation system.
