What is pseudo parkinson's disease?

Not Parkinson's: Parkinson's disease is a disorder of the brain characterized by slowness of movement, rigidity of muscles and is caused by a deficiency of Dopamine in the brain. Many drugs such as the anti-psychotics can cause a parkinson's-like picture, as can some severe infections and metabolic disorders. I believe the term is more of a lay term than what is truly found in medical books.

Parkinson symptoms: Parkinsonism symptoms caused by secondary factors especially drugs, post stroke etc & not responding to usual antipd medications.
