Used as adjunctive therapy for symptomatic treatment of parkinsonian syndrome (e.g., parkinsonism, Parkinson disease [paralysis agitans]) in patients who exhibit a deteriorating response to levodopa/carbidopa; designated an orphan drug by FDA for this condition. Appears to be most beneficial when used during the early stages of the “wearing off” effect. Especially useful in improving “end-of-dose” motor fluctuations.

Has been used as monotherapy in patients with newly diagnosed parkinsonian syndrome. Because selegiline is well tolerated and possibly neuroprotective (i.e., reduces the rate of progression of parkinsonian syndrome ), some clinicians initiate therapy with selegiline in such patients, reserving levodopa or another agent (i.e., dopamine agonist) until manifestations become severe enough to warrant more aggressive therapy. However, the manufacturers state that there is no evidence from controlled studies indicating that selegiline provides benefit in the absence of concurrent levodopa therapy.

Has been used with equivocal results for the palliative treatment of mild to moderate dementia of the Alzheimer’s type (Alzheimer’s disease, presenile or senile dementia).
