Cocaine use impairs loss prediction ability

 New York, February 4: Despite unfavourable consequences like imprisonment or loss of relationships, cocaine addicts may continue their habit because their brain circuits responsible for predicting emotiol loss are impaired, says a study. “We found that people who were addicted to cocaine have impaired loss prediction siglling in the brain,” said lead author of the study Muhammad Parvaz from the Icahn School of Medicine at Mount Sii. “This study shows that individuals with substance use disorder have difficulty computing the difference between expected versus unexpected outcomes, which is critical for learning and future decision making,” Parvaz added. The researchers recorded the brain activity of 75 participants (50 cocaine users and 25 healthy controls) using EEG, a test that detects electrical activity in the brain, while they played a gambling game.
