Objective:
To research the relation between blood alcohol concentration (BAC) and neurobehavioral function after drinking.
Methods:
The neurobehavioral ability index (NAI) of 233 volunteers were measured with computer-administered neurobehavioral evaluation system-Chinese3 (NES-C3).
Results:
The NAI of simple visual reaction time and mental arithmetic declined when BAC was more than 0.157 mg/mL, the NAI of benton visual retention, length discrimination and digit cancel declined significantly when BAC was more than 0.204 mg/mL.
Conclusion:
The neurobehavioral function declined significantly when BAC increased and recovered gradually when BAC declined due to the elimination of alcohol in blood.
