    Is there a difference between parkinson's syndrome and parkinson's disease?
    la0577 posted:
    I have recently seen parkinson's referred to as parkinson's syndrome and parkinson's disease. Is there a difference between the two or is it just referred to in two different terms?
    Mark A Stacy, MD responded:
    Parkinson's Disease, or idiopathic Parkinson's Disease (PD), is a condition with a tremor at rest, slowness of movement, stiffness of the limbs and balance difficulty. These symptoms almost always improve with medications.

    Parkinsonism is a condition that looks like PD with usually very little tremor, that does not respond as well to antiparkinson therapy. Some causes of parkinsonism include symptoms caused by anti-psychotic or anti-nause medications, stroke, thyroid abnormalities, low vitamin B12, normal pressure hydrocephalus or one of the Parkinsonism Plus Syndromes. These include Progressive Supranuclear Palsy, Cortico-Basal Ganglionic Degeneration and Multiple System Atrophy.

    hello, dr. stacy --

    i apologize, but i'm not sure i understood your answer. so is parkinson's "syndrome" one of the conditions that could be considered a form of parkinsonism, and therefore different altogether from parkinson's disease itself?

    Mark A Stacy, MD replied to susiemargaret's response:
    Hi, susiemargaret.
    PD can be a parkinson syndrome, but it is the only one that responds predictably to anti-parkinson medications. All other conditions that look like parkinsonism, would be a parkinson syndrome, but could not be called PD.

    We try to split PD out from the parkinson syndrome by looking for extra features, like bladder dysfunction, markedly low blood pressure, seizures, and by looking for a response to medications. Extra features on examination, or a poor response to levodopa, should prompt further imaging and laboratory work-up.

    Hi Dr. Stacy,

    I also wanted to know what the prognosis for Parkinsonism induced by head trauma is versus for Parkinson's disease. I seem to find the prognosis for Parkinson's disease but nothing on Parkinsonism. Can I assume that they are the same?

    hello, dr. stacy --

    thank you for explaining -- a most interesting distinction that i don't think i've ever understood before.

    i hope you know what a huge asset you are to this exchange.
