Abstract

Neuroscience has long sought to develop methods that can “edit” or even “erase” memories, with the aim to provide treatments for memory-related neurological and psychiatric diseases such as anxiety and addiction. Current efforts are heavily focused on modifying cognitive behavioral therapy protocols or pharmacological treatments, but the efficacy and safety of these methods have been called into question by several studies. Advances in modern technology and the rapid emergence of techniques that can directly stimulate/alter neuronal activity, such as neuromodulation, have great potential in achieving the goal of memory modification for treating dementia such as Alzheimer’s disease. However, more research and validation studies are required before these memory editing technologies can be applied clinically. In this mini-review, we compare and highlight the advantages and disadvantages of cognitive behavioral therapy, pharmacological methods, and neuromodulation techniques. We believe that neuromodulation techniques will play a key role in overcoming the challenges of translating memory-manipulating techniques to clinical applications.
