Overdoses of drugs can cause death. After a large number of deaths happened in 2009, doctors were confused whom to prescribe what level of drug dose. Since then, health care professionals were searching for better ways to distinguish patients who followed the prescription according to the prescribed, and who didn’t. Seems their worries are over. At Northwestern Memorial Hospital, the doctors are training themselves with a latest technology in order to better recognize the signs of addiction. A video game has been designed based on the research of Dr. Michael M. Fleming of Northwestern University Feingberg School of Medicine that utilizes the same technology used to train FBI agents in interrogation tactics – a combination of self-disclosure and non-verbal cues. With the help of the video game, doctors can identify signs of addiction easily in their patients.
