How is catatonia diagnosed?
There is no definitive test for catatonia however a physical exam and testing is conducted to rule out other conditions. Some of the ways in which catatonia is diagnosed include:
- The use of BFCRS

- Blood test
Blood test is also carried out, it can help to rule out electrolyte imbalances . These can cause changes in mental function. With a blood test you can know if there is pulmonary embolism or blood clot in the lungs, as this can lead to catatonia symptoms.
- CT or MRI scans
