Computerized Assessment System
The Computerized Assessment System (CDR system) is a computerized battery of cognitive testing tool, developed to assess both enhancement and impairment of human cognitive performance. The CDR system is a series of brief neuropsychological tests that assess major aspects of cognitive function known to be influenced by a wide variety of factors including trauma, fatigue, stress, nutrition, ageing, disease (both physical and mental), medicines and drugs. The CDR systems simplicity, sensitivity and specificity make it acceptable to be used in clinical trials with either healthy subjects or diseased patient populations. The CDR system tasks have proven validity in definitively measuring cognitive function in a variety of domains including attention, working memory, episodic secondary memory, executive function, and motor skill.
