Levodopa (L-dopa). A substance used in the treatment of Parkinson's disease. Levodopa can cross the blood-brain barrier that protects the brain. Once in the brain, it is converted to dopamine and thus can replace the dopamine lost in Parkinson's disease.
In general, though, at introductory doses, levodopa does not cause such effects. The older the patient is, the more comorbid issues there are (such as dementia, a stroke, preexisting psychiatric disease); these factors and higher doses make one more likely to develop such things.
