Work-related stress (WS) can result in considerable and extensive changes in physiological and psychological performance.WS beyond the optimal levels induces anxiety, confusion, exhaustion, and burnout. Chronic WS affects neurocognitive performance, particularly attention and visuospatial memory. Essence of chicken (EC) has been reported to improve neurocognitive function after mental stress. To investigate the beneficial effects of EC in improving neurocognitive performance under WS, we conducted a randomized, double blind trial. Total 102 young workers in New Taipei City with high WS, evaluated using the Individual Subjective Perception Job Stress Scale scores (>36 for job leaders and 33 for nonleaders) were recruited. Fiftyone participants received 70mL of EC and 51 received a placebo daily for 2 weeks. Blood tests and neurocognitive assessment were performed before treatment, at the end of treatment, and 2 weeks after treatment. EC improved the performance of participants with high depression scores in the form-color associative memory test, used for assessing shortterm memory. Although creatinine and glutamic-pyruvic transaminase (GPT) levels increased inweek 2, but the levels returned to the baseline in week 4. Blood urea nitrogen (BUN) levels decreased in week 4. EC significantly improved short-term memory in participants with highWSand concomitant depressivemood, although it slightly increased GPT and creatinine levels and reduced BUN levels. The long-term treatment effects of EC warrant further investigation.
