Attention Deficit Disorder With Hyperactivity, Gastrointestinal Diseases
Conditions
Brief summary
This study is to examine the gut problems in children with attention deficit hyperactivity disorders (ADHD) and is conducted by the Department of Psychiatry of Alice Ho Miu Ling Nethersole Hospital. Children with ADHD who attend our department will be recruited with their parents/guardians' consent. Only the primary caregiver will be invited for an interview to assess the recruited children's gut problems, autistic features, emotional problems, diet pattern and medical history. The data will be compared with normal children who are recruited as control in local primary schools. The aim of this study is to know whether children with ADHD have higher chance of gut problems, and to assess other factors associated with the linkage.
