Long-term bidirectional association between asthma and attention deficit hyperactivity disorder: A big data cohort study.

ABSTRACT:

Background

Previous studies have argued that attention deficit hyperactivity disorder (ADHD) is associated with asthma. However, reliable evidence to verify this association has not yet been reported.

Objectives

To investigate the bidirectional association between asthma and ADHD through a 12-year big data cohort study.

Measurements and main results
