[Pimavanserin and trazodone combination in behavioral disorders in severe dementia with Lewy bodies].

Introduction: Dementia with Lewy bodies (DLB) is characterized by neurocognitive disorders associated with core clinical features including hallucinations. There is currently no cure but a combination of symptomatic treatments: clozapine is commonly used in DLB-related psychosis. Pimavanserin is a serotonin 5HT-2A receptor inverse agonist that has recently been shown to reduce psychosis related to dementia.
