A pill to erase bad memories?

Scientists believe a common heart medicine may be able to banish fearful memories from the mind.

The Dutch investigators believe beta-blocker drugs could help people suffering from the emotional after-effects of traumatic experiences.

They believe the drug alters how memories are recalled after carrying out the study of 60 people, Nature Neuroscience reports.

But British experts questioned the ethics of tampering with the mind.
Paul Farmer, chief executive of mental health charity Mind, said he was concerned about the "fundamentally pharmacological" approach to people with problems such as phobias and anxiety.


Professor Neil Burgess of the Institute of Cognitive Neuroscience said the research merely demonstrates that the beta blockers reduce a person's startle response, breaking the association of the spider to these unconscious responses.

And Dr Daniel Sokol, lecturer in Medical Ethics at St George's, University of London, said memories were important, for people to learn from their mistakes for example.
"Removing bad memories is not like removing a wart or a mole. It will change our personal identity since who we are is linked to our memories. It may perhaps be beneficial in some cases, but before eradicating memories, we must reflect on the knock-on effects that this will have on individuals, society and our sense of humanity."
