A lumbar puncture is done to: Find a cause for symptoms possibly caused by an infection (such as meningitis), inflammation, cancer, or bleeding in the area around the brain or spinal cord (such as subarachnoid hemorrhage).
What is chorea? Chorea refers to involuntary movements characterized by their random, brief, and non-rhythmic character. They are often described as seeming to âflowâ from one body part to another unpredictably, though they can also be confined to a single area of the body (such as the mouth area or hands).
Ballism or ballismus is considered a very severe form of chorea in which the movements have a violent, flinging quality. This movement disorder most often involves only one side of the body (ie, hemiballism or hemiballismus). Occasionally, bilateral movements occur (ie, biballism or paraballism).
