Advances in the pharmacotherapeutic management of dementia with Lewy bodies.

INTRODUCTION

Dementia with Lewy bodies (DLB) is the second most common type of dementia in people over 65 years of age. Given the complex clinical phenotype, the management of DLB may be challenging, especially considering that there is limited evidence about specific interventions, and there are currently no Food and Drug Administration (FDA)/European Medicines Agency (EMA)-approved medications.

AREAS COVERED

This article provides an overview of the current pharmacotherapy in DLB and gives review to the most recent drug candidates in clinical trials.

EXPERT OPINION

Commonly prescribed drugs are primarily aimed at treating the most troublesome clinical features of DLB. Although these medications provide some benefit to symptoms, there is, unfortunately, a lack of DLB-specific evidence on effective treatments and their off-label use. Indeed, most treatments used come from clinical trials on patients with Alzheimer's disease or Parkinson's disease. Thus, there is an urgent need for randomized clinical trials in DLB patients. Despite several challenges, potential new drugs are in ongoing clinical trials; furthermore, as our understanding of molecular and cellular mechanisms underlying DLB broaden, it is likely that we will identify novel drug targets for the development of better and more effective symptomatic products and disease-modifying therapies.
