What tests are done to diagnose neuroleptic malignant syndrome (NMS)?

ANSWER

Your doctor will look for the two main symptoms of NMS: a high temperature and stiff muscles. To be diagnosed with it, you also need to have a few other warning signs, like a fast heartbeat, low or high blood pressure, and sweating.

Some other disorders have symptoms that are similar to NMS. To figure out if you have it, your doctor will do one or more of these tests:

  • Blood and urine tests
  • Brain imaging scans
  • Test of spinal fluid
  • EEG to find electrical problems in the brain
