Whether it is possible to cure secondary parkinsonism or not depends on its cause, as those suffering from parkinsonism due to a medication can often reverse the symptoms by discontinuing the medication, according to Mayo Clinic. Medication used for Parkinson's disease can alleviate some symptoms.
Secondary parkinsonism refers to symptoms typical of Parkinson's disease caused by other medical issues, as reported by Mayo Clinic. Potential causes include repeated head trauma, toxin exposure, brain lesions and various metabolic diseases. Drugs used for treating Parkinson's disease may help secondary parkinsonism patients. However, these drugs typically do not reverse the underlying cause of secondary parkinsonism itself.
