Primary Outcome Measures:
  • Boost in language learning success (percent hits) through neuromodulation

Secondary Outcome Measures:
  • Stability of language learning success after one week, one month, and one year

Estimated Enrollment: 60
Study Start Date: January 2005
Estimated Study Completion Date: June 2006
Detailed Description:

Our prior work shows that d-amphetamine and the dopamine precursor levodopa markedly improve word learning success in healthy subjects. In this randomized, placebo-controlled, double-blind clinical trial, we probe whether a selective d2/d3 dopamine agonist (pramipexole) or cholinergic neuromodulation (rivastigmine), after a titration period of five days, will yield a learning enhancement comparable to using levodopa in healthy subjects. The expected scientific results will strengthen the basis for transferring neuromodulatory interventions from the laboratory to stroke patients with language dysfunctions.
