Summary
This study provides normative data for the Milan Automated Neurobehavioral System (MANS) in healthy adults. Age, education, and sex significantly impact MANS performance, enabling clinical use.
Area of Science:
- Neuroscience
- Clinical Psychology
- Psychometrics
Background:
- The Milan Automated Neurobehavioral System (MANS) is used in field studies to assess neurotoxicant effects.
- Lack of normative data has limited its clinical application.
Purpose of the Study:
- To establish age-, sex-, and education-specific norms for the MANS in a healthy adult population.
- To evaluate the MANS' suitability for clinical neurobehavioral assessments.
Main Methods:
- 236 healthy adults (151 men, 85 women) aged 39-94 years completed the MANS.
- MANS subtests included simple visual reaction time, digit symbol substitution, serial digit learning, and Benton visual retention.
- Neurobehavioral evaluations were comprehensively performed.
Main Results:
- Age and years of education significantly influenced performance across all four MANS subtests.
- Sex was a significant factor in simple visual reaction time and Benton visual retention.
- Normative values were generated for healthy individuals aged 50-79 years.
Conclusions:
- The MANS can be clinically applied with the established normative data.
- Age, education, and sex are crucial demographic factors for interpreting MANS results.
- This study facilitates the MANS' use in clinical neurobehavioral evaluations.
