Chorea

    The Definition of Chorea:

    An irregular, unpredictable, random, jerky, movements that flow from one body part to another or a complete inability to sustain a steady body position. Athetosis is slower than chorea. It is acceptable to use the term "choreoathetosis".

    Treatment

    Treatment needs to proceed with caution. Frequently treatment settles chorea but the functional status of the patient is worsened.

    Medications Options:

    A variety of medications can be used to help settle the movement disorder including; Tetrabenazine, Reserpine, Trilafon (perphenazine), other Neuroleptics, and Haldol.
