Introduction: The study assessed symptoms of ADHD in a group of school children after release from quarantine.
Methods: This cross-sectional study included 20 boys with ADHD. The parents were annually interviewed for follow-up in February. The last annual questionnaire is considered the Before-Quarantine interview, which was repeated during the first follow-up visit after lockdown release (After-Quarantine interview).
Results: After quarantine, the median score increased significantly compared to before quarantine [51 (31-61) to 86 (14-98), p < 0.001]. Attention span decreased significantly (p < 0.001), and activity levels increased significantly after quarantine (p < 0.001). The online schooling score indicated problematic behavior in all but one child. Kids who received rehabilitation sessions had significantly lower scores before and after quarantine.
Conclusion: COVID-19 lockdown and school closure have a deleterious effect on the severity of symptoms of children with ADHD. These children showed a problematic performance of online schooling.
