Researchers have found that certain anti-cancer drugs improved the long term memory of mice. These drugs, called histone deacetylase (HDAC) inhibitors are hoped to strengthen connectors in the brain and improve long term memory in people with Alzheimers and other brain diseases. One of the co-authors of the study, Marcelo Wood, is quoted in this article, “We have demonstrated for the first time that HDAC inhibitors applied directly to the hippocampus enhance memory and synaptic plasticity in the brain, and we now know a molecular mechanism through which these enhancements occur.”
