memory boost

Imagine if increasing a certain type of epigenetic enzyme could ease anxiety or cure post-traumatic stress disorder (PTSD) by simply erasing troubling memories? What if it could also enhance cognitive abilities and improve long-term memory and learning? In previous blog articles, researchers found that an immune-suppressing drug that inhibits HDACs could stop aversive memories and the epigenetic mechanism known as histone acetylation might play a role in memory plasticity. Although we are far from developing epigenetic therapies to erase traumatic [more…]

Researchers at the University of Alabama at Birmingham have discovered a potential epigenetic explanation for why individuals with epilepsy, particularly temporal lobe epilepsy, usually experience memory loss. They even propose a way to undo that loss of memory. Published recently in the Annals of Translational and Clinical Neurology, a group of UAB scientists believes their results could progress our understanding of numerous other disorders involving memory loss and could lead to a therapeutic approach for restoring proper memory function via [more…]

Researchers from Rush University Medical Center and Brigham and Women’s Hospital (BWH) conducted a study recently demonstrating how an epigenetic alteration to DNA of the brain is connected to Alzheimer’s disease. The team looked at DNA methylation, which is an epigenetic mechanism that occurs when a methyl group is added to the cytosine or adenine of DNA. This epigenetic mechanism, as well as others such as DNA demethylation and histone acetylation, have the ability to turn on or off genes. [more…]
