Insights
Early non-pharmacologic interventions like occupational and speech therapy may reduce the incidence of Attention Deficit Hyperactivity Disorder (ADHD) in at-risk preschoolers with a family history of the condition.
Area of Science:
- Developmental Psychology
- Pediatrics
- Neurodevelopmental Disorders
Background:
- Preschool children with inattention, speech, or motor delays are at high risk for Attention Deficit Hyperactivity Disorder (ADHD).
- Early identification and intervention are crucial for managing neurodevelopmental conditions.
Purpose of the Study:
- To investigate the efficacy of non-pharmacologic early interventions (occupational therapy, speech therapy) in reducing the incidence of ADHD.
- To assess the long-term outcomes of high-risk preschool children.
Main Methods:
- A cohort of 51 preschool children (ages 2-4.5) with developmental delays were followed until school age (8-10 years).
- Participants underwent comprehensive assessments including IQ testing, neurological examinations, and ADHD diagnostic questionnaires (DSM-III-R).
- Medical and family history data were collected.
Main Results:
- 20 out of 51 children (39%) were diagnosed with ADHD at school age.
- A family history of ADHD was noted in 8 of the 20 children diagnosed with ADHD.
- Early intervention appeared to reduce ADHD incidence in children with a family history, though sample size limits definitive conclusions.
Conclusions:
- Non-pharmacologic early interventions may be beneficial in mitigating ADHD development in high-risk children, particularly those with a familial predisposition.
- Further research with larger sample sizes is needed to confirm these findings and establish causal links.
Abstract:
The purpose of this study was to examine whether early intervention by non-pharmacologic means (occupational therapy and speech therapy) can decrease the incidence of ADHD in a group of preschool children at high risk for developing this syndrome. Fifty-one children who suffered at the age of 2-4.5 years from inattention, speech delay and/or motor delay with or without hyperactivity were reexamined at the age of 8-10 years (average 8.9 +/- 1.0 years) by a developmental pediatrician and a developmental psychologist, using the following tests and questionnaires: WISC-R IQ test, Touwen and Prechtl neurological examination for soft neurological signs and the DSM-III-R questionnaire for parents and teachers for the assessment of inattention and hyperactivity. A detailed medical questionnaire was also completed. Of 51 children, 20 (39%) had ADHD. Of these 20 children, 8 had a history of ADHD in other siblings. We found that in children with a family history of this syndrome early intervention reduced the incidence of ADHD at school age although the small numbers limit conclusions and need further replication.
