ABSTRACT
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. Trazodone is a serotonin reuptake inhibitor and a 5-HT2 receptor antagonist it is effective in the treatment of the frontal syndrome and is commonly used in frontotemporal degeneration. PATIENTS ANDMETHODS:
We describe three patients with DLB, hospitalized in the cognitive-behavioral unit of the University Hospitals of Strasbourg, who presented with major visual hallucinations, delusion, and an orbitofrontal syndrome including disinhibition, agitation, and irritability. The 3 patients were intolerant of low-dose Clozapine (neutropenia for one, somnolence for the other and Pisa syndrome and falls for the last one). We evaluated the Neuropsychiatric Inventory (NPI) before and after the introduction of both treatments.RESULTS:
Given their psychotic and frontal symptoms, we used Pimavanserin and Trazodone simultaneously. After 4 to 6 weeks of treatment, a marked improvement was observed in all 3 patients, with a decrease of the NPI scores from a mean of 88 to 38. DISCUSSION ANDCONCLUSION:
To our knowledge, there is no previously described combination of these two treatments in DLB. A clinical trial combining these two molecules against pervasive behavioral disorders in DLB would be interesting in view of these preliminary results.Key words
