A small number of clinical studies have investigated the effects of the noradrenergic agonist dextroamphetamine in patients recovering from motor deficits following stroke. To determine whether these findings extend to communication deficits subsequent to stroke, we administered dextroamphetamine, paired with speech\/language therapy, to patients with aphasia.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>\n                        <jats:bold>\n                          <jats:italic>Methods<\/jats:italic>\n                        <\/jats:bold>\n                        \u2014\n                      <\/jats:italic>\n                    <\/jats:bold>\n                    In a prospective, double-blind study, 21 aphasic patients with an acute nonhemorrhagic infarction were randomly assigned to receive either 10 mg dextroamphetamine or a placebo. Patients were entered between days 16 and 45 after onset and were treated on a 3-day\/4-day schedule for 10 sessions. Thirty minutes after drug\/placebo administration, subjects received a 1-hour session of speech\/language therapy. The Porch Index of Communicative Ability was used at baseline, at 1 week off the drug, and at 6 months after onset as the dependent language measure.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>\n                        <jats:bold>\n                          <jats:italic>Results<\/jats:italic>\n                        <\/jats:bold>\n                        \u2014\n                      <\/jats:italic>\n                    <\/jats:bold>\n                    Although there were no differences between the drug and placebo groups before treatment (\n                    <jats:italic>P<\/jats:italic>\n                    =0.807), by 1 week after the 10 drug treatments ended there was a significant difference in gain scores between the groups (\n                    <jats:italic>P<\/jats:italic>\n                    =0.0153), with the greater gain in the dextroamphetamine group.
