From 2001 so I don't know what has been done since then.

Background and Purpose
recovery when administered late (days to weeks) after brain injury in animals. 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.
Methods
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.
Results
after the 10 drug treatments ended there was a significant difference in gain scores between the groups (
the greater gain in the dextroamphetamine group. The difference was still significant when corrected for initial aphasia
severity and age. At the 6-month follow-up, the difference in gain scores between the groups had increased; however,
the difference was not significant (
Conclusions
recovery from aphasia in a small group of patients in the subacute period after stroke. Neuromodulation with
dextroamphetamine, and perhaps other drugs that increase central nervous system noradrenaline levels, may facilitate
recovery when paired with focused behavioral treatment.
