Childhood histories of attention-deficit hyperactivity disorders in Japanese methamphetamine and inhalant abusers: preliminary report.
The present study examined childhood histories of attention-deficit hyperactivity disorder (ADHD) in 54 methamphetamine and 12 inhalant abusers using the Wender Utah Rating Scale. The inhalant abusers experienced initial drinking at a younger age than methamphetamine abusers (P=0.038). The Wender Utah Rating Scale score was significantly higher in the inhalant abusers than in the methamphetamine abusers (P=0.013) although 83.3% of inhalant and 55.6% of methamphetamine abusers had higher scores than the cut-off for ADHD. These findings suggest that drug abuse is associated with childhood ADHD, and that inhalant abusers have a higher incidence of childhood ADHD than methamphetamine abusers.
