What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome is a life-threatening, neurological disorder most often caused by an adverse reaction to neuroleptic or antipsychotic drugs. Symptoms include:
In most cases, the disorder develops within the first two weeks of treatment with the drug; however, the disorder may develop at any time during the therapy period. The syndrome can also occur in people taking anti-Parkinsonism drugs, known as dopaminergics, if those drugs are discontinued abruptly.
Generally, intensive care is needed. The neuroleptic or antipsychotic drug is discontinued, and the fever is treated aggressively. A muscle relaxant may be prescribed. Dopaminergic drugs may be useful.
Early identification of and treatment for individuals with neuroleptic malignant syndrome improves outcome.
How can I or my loved one help improve care for people with neuroleptic malignant syndrome?
Consider participating in a clinical trial so clinicians and scientists can learn more about neuroleptic malignant syndrome and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.
All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.
