Neuroleptic malignant syndrome is a potentially fatal reaction that has been linked to Risperdal (risperidone), a popular antipsychotic medication. Risperdal is used for the treatment of schizophrenia, mania, mixed episodes and bipolar disorder. Neuroleptic malignant syndrome presents as fever, muscle stiffness, altered mental status and autonomic dysfunction.

How is Neuroleptic Malignant Syndrome Diagnosed?
Testing plays an important role in the evaluation of Risperdal (risperidone) users who may be suffering from neuroleptic malignant syndrome (NMS). Laboratory analysis can help confirm the syndrome, some tests may rule out other disorders, and other steps may be taken to monitor patients for complications.
In patients who are suspected of having neuroleptic malignant syndrome, brain imaging studies and lumbar puncture may be ordered to rule out brain disease. Most people with the disorder appear normal on MRI and CT scans. Diffuse cerebral edema has been reported in rare cases, as well as signal abnormalities in the cerebellum and basal ganglia. Cerebrospinal fluid is typically normal; however, a nonspecific elevation in protein has been reported in some patients.
An EEG may be performed to rule out non-conclusive status epilepticus. In Risperdal users with neuroleptic malignant syndrome, slow brain wave activity is often noted.
In 2011, an international consensus group established a diagnostic criteria for neuroleptic malignant syndrome. This information is based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition:
A: The development of severe muscle rigidity and elevated temperature associated with the use of antipsychotic medication.
B: Two (or more) of the following:
- Changes in consciousness ranging from confusion to coma
- Elevated or labile blood pressure
- Laboratory evidence of muscle injury (e.g., elevated CK)
C.The symptoms in Criteria A and B are not due to another substance (e.g., phencyclidine) or a neurological or other general medical condition (e.g., viral encephalitis).
D. The symptoms in Criteria A and B are not better accounted for by a mental disorder (e.g., Mood Disorder with Catatonic Features)
