The effect of haloperidol on stuttering
PB Rosenberger, JA Wheelden and M Kalotkin
Haloperidol was compared with placebo in the treatment of 8 young adult
stutterers in a double-blind crossover study involving 6 sequential
observations over periods of 6 or 12 weeks. The drug was found to have a
significant effect on the percentage of time subjects were dysfluent but
not on the number of dysfluencies per minute. The authors discuss possible
reasons for this finding.
