Why are anticholinergics used more often than Amantadine, for drug-induced Parkinsonism?

What the title says. Anticholinergics have a burden on memory, and cognition in general. While amantadine doesn't seem to. However, almost every psychiatrist I know, use anticholinergics to avoid extrapyramidal symptoms.
