| | Parkinsonism |
 | | Other causes of parkinsonism, such as head trauma, drug ingestion, carbon monoxide, cyanide, and manganese poisoning, are usually obvious; normal-pressure hydrocephalus and Jakob-Creutzfeldt disease may not be. |
 | | Secondary parkinsonism, e.g., resulting from toxic, tumors, infarcts, hydrocephalus, post-trauma, post-encephalitic Parkinsonism, or AIDS, also should be considered in the differential diagnosis but is relatively easy to differentiate from PD on the basis of other clinical criteria. |
 | | Its place in the treatment of Parkinson's disease is still controversial, but it is probably best regarded as an L-dopa sparing agent that also prolongs the effect of L-dopa in patients with end-of-dose failure. |
