A common drug can selectively target long-term memories better than other therapies.
A common blood-pressure drug can selectively dampen fearful memories, according to research published today in Nature Neuroscience.
he research builds on preliminary tests in patients with post-traumatic stress disorder (PTSD), in which people who have experienced severe trauma, such as rape, are plagued by disturbing and uncontrollable memories of the event. "Anytime you can reduce the emotional component of a memory while leaving the other content intact is very exciting," says Seth Norrholm, a neuroscientist at Emory University, in Atlanta, who was not involved in the research. "We want patients to understand what triggers their fear without feeling the anxiety."
