结局指标

主要结局

Change in score of battery of cognitive function tests

时间窗: Change from before to after diphenhydramine administration (30, 60, 210, 240, 450, and 480 minutes after diphenhydramine)

Change in the results of the CANTAB battery of cognitive function tests (reaction time, rapid visual information processing, paired associates learning, spatial working memory, digit span) and visual analog scale for sedation after diphenhydramine administration compared to baseline

次要结局

  • Elderly vs. adult change in score of battery of cognitive function tests after diphenhydramine(After diphenhydramine administration (30, 60, 210, 240, 450, 480 minutes after diphenhydramine administration))
  • Elderly vs. adult score of battery of cognitive function tests at specified time points(Before and after diphenhydramine administration (30, 60, 210, 240, 450, 480 minutes after diphenhydramine administration))
  • Elderly vs. adult diphenhydramine AUC(Immediately after diphenhydramine administration to 480 minutes after diphenhydramine administration)
