Answers To Writers' Questions

Dear Fiction Dr.,

Are there any medications that make people open to suggestion and are there any meds that will make them lose their memories? If there are, how do they work?

Thanks,
Stefani


Dear Stefani,

The barbiturates as a class are sedatives that interfere particularly with judgment and higher cognitive function. Psychiatrists hypothesize that because lying is more complex than telling the truth, suppression of the higher cortical functions may lead to the uncovering of the "truth".

Sodium thiopental or Pentothal is a barbituate used in general anesthesia. It is also still used in some places as a truth serum. The drug tends to make subjects chatty and cooperative with interrogators. A low dose induces semi-hypnosis and loosens the tongue like having had several drinks. The patient loses inhibition and is more open to suggestion (some believe the drug is able to uncover repressed memories).

However, the reliability of confessions made under Thiopental is dubious, because a practiced liar or someone who has a false story firmly established would still be quite able to lie while under the influence of the drug.

Sodium thiopental is an amnestic and a hypnotic; the patient does not remember the experience.

Hope that helps!

Best Regards,

Dr. Karen
