Evaluation of neuropsychological development of children diagnosed with primary monosymptomatic nocturnal enuresis: A pilot study.

OBJECTIVE

Studies on primary monosymptomatic nocturnal enuresis have supported neuromotor development delay. This study aims to examine the neuropsychological development of children with primary monosymptomatic nocturnal enuresis.

MATERIAL AND METHODS

This study included 30 children diagnosed with primary monosymptomatic nocturnal enuresis and 30 healthy children. Both groups were analyzed by pediatric psychologists using the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Bender Gestalt Visual Motor Detection test. The WISC-R test is an intelligence test that includes six verbal subscales (information, similarities, arithmetic, vocabulary, judgment, and digit span) and six performance subscales (picture completion, picture arrangement, block design, object assembly, coding, and labyrinths). The Bender Gestalt test is a psychological assessment instrument used to evaluate visuomotor functioning, visuospatial functions, spatial memory, visuomotor integration skills, and visual perception skills.

RESULTS

There were no differences in age (7.66±0.9 versus 8±1.07 years, p>0.05) or sex (20 females versus 20 males, p>0.05) between the groups. Picture completion (p=0.024), picture arrangement (p=0.001), and object assembly test (p=0.000) performance was found to be worse in subjects with primary monosymptomatic nocturnal enuresis. Similarity (p=0.021) and judgment tests (p=0.048) of the verbal subtests were also found to be delayed in the nocturnal enuresis cases.

CONCLUSION

Our results suggest that children with nocturnal enuresis have lower performance compared with the control group in terms of abstract thinking, correct expression of thought, cause-result relation, short-term memory, and problem-solving ability. These children should be routinely tested by neurodevelopment tests and receive support in areas in which they are delayed.
