Modulating metals as a therapeutic strategy for Alzheimer’s disease

Abstract

In 1906, Alois Alzheimer first characterized the disease that bears his name. Despite intensive research, which has led to a better understanding of the pathology, there is no effective treatment for this disease. Of the drugs approved by the US FDA, none are disease modifying, only symptomatic. Unfortunately, there have been a number of failed clinical trials in the past 10 years where studies show either no cognitive improvement or, worse, serious side effects associated with treatment. Hence, there is a need for the field to look at alternative approaches to therapy. In this review, we will discuss how metal dyshomeostasis occurs in aging and Alzheimer’s disease. Concomitantly, we will discuss how targeting this dyshomeostasis offers an effective and novel therapeutic approach. Thus far, compounds that mediate these effects have shown great potential in both preclinical animal studies as well as in early-stage clinical trials.
