title: Effect of propranolol on naming in chronic Broca's aphasia with anomia.
abstract: Previous research suggests that the noradrenergic system modulates flexibility of access to the lexical-semantic network, with propranolol benefiting normal subjects in lexical-semantic problem solving tasks. Patients with Broca's aphasia with anomia have impaired ability to access appropriate verbal output for a given visual stimulus in a naming task. Therefore, we tested naming in a pilot study of chronic Broca's aphasia patients with anomia after propranolol and after placebo in a double-blinded crossover manner. Naming was better after propranolol than after placebo, suggesting a potential benefit from propranolol in chronic Broca's aphasia with anomia. Larger follow-up studies are necessary to further investigate this effect.
