Mental and somatic health and social adjustment in ordinary school children during childhood and adolescence related to central nervous functions as expressed by a complex reaction time.
A cohort of ordinary Swedish children were followed up from school entry through childhood and adolescence and checked retrospectively from birth to the age of 6 years regarding psychiatric and physical health and contact with the social welfare authorities. The children were allocated to different risk groups at age 7 on the basis of their psycho-physical development expressed as complex reaction time (CRT). It was previously shown that many of the slow CRT children have problems in psychomotor and language development at school, and that many leave compulsory school with poor achievements in Swedish and gymnastics as continuing signs of their developmental delay. This study shows that slow CRT children have an increased prevalence of child psychiatric problems. At an early age there were symptoms of aggression, hyperactivity and withdrawal in conjunction with developmental delay. During adolescence, depression, maladjustment and psycho-somatic disorders were prominent features, often in association with developmental delay, dyslexia and poor motoric skill. These children could have a disadvantage at school and in society and they felt themselves "handicapped" and were stressed by feelings of limited future possibilities. In adolescence, many of them were in need of help, especially financial aid from the social welfare services. The findings stress that a slow cognitive processing ability seen as a slow CRT must be considered a handicap of importance and a risk-factor in the society of today, with primary or secondary psychic and social manifestations often in a multifactorial setting of biological co-morbidity and family problems. In contrast, an advanced CNS development with a fast CRT may be seen as a protective factor.
