Using a double-blind, placebo-controlled, crossover design, we studied
the effect of bromocriptine (15 mg daily) in 20 men with chronic nonf
luent aphasia. The study was conducted over a 28-week period in two ph
ases. In phase I, the patients received either bromocriptine or placeb
o; in phase II the treatments were crossed over. We evaluated each pat
ient's language and nonverbal cognitive skills at the beginning and en
d of each phase and 6 weeks after completion of phase II. When compare
d with placebo treatment, bromocriptine did not significantly improve
the patients' speech fluency, language content, overall degree of apha
sia severity, or nonverbal cognitive abilities, Based on these results
, bromocriptine is not recommended as monotherapy for the treatment of
chronic nonfluent aphasia.
