Neuroleptic malignant syndrome is a rare but potentially life-threatening reaction to the use of almost any of a group of antipsychotic drugs or major tranquilizers (neuroleptics). These drugs are commonly prescribed for the treatment of schizophrenia and other neurological, mental, or emotional disorders.

NMS can damage muscles and cause very high or low blood pressure. If you're not treated, you can get serious problems, like: Kidney failure. Heart and lung failure.

What is the mortality rate of neuroleptic malignant syndrome?

NMS can be fatal with estimated mortality rates as high as 20%. Patients experiencing certain severe complications, including renal failure, have been associated with mortality as high as 50%, stressing the need for early recognition and treatment.

Is neuroleptic malignant syndrome an emergency?

Is TD irreversible?

Tardive dyskinesias (TD) are persistent and often irreversible involuntary movements that occur following prolonged neuroleptic therapy (Sethi, 2004).

How can you prevent NMS?

The most important aspect of treatment is prevention. This includes reducing risk factors (e.g. dehydration, agitation and exhaustion), early recognition of suspected cases and prompt discontinuation of the offending agent.

How do you manage neuroleptic syndrome?

Nonpharmacologic management centers on aggressive supportive care including vigilant nursing, physical therapy, cooling, rehydration, anticoagulation. Pharmacologic interventions include immediate discontinuation of antipsychotics, judicious use of anticholinergics, and adjunctive benzodiazepines.

What is the difference between NMS and serotonin syndrome?

NMS and serotonin syndrome are rare, but potentially life-threatening, medicine-induced disorders. Features of these syndromes may overlap making diagnosis difficult. However, NMS is characterised by 'lead-pipe' rigidity, whilst serotonin syndrome is characterised by hyperreflexia and clonus.

How does neuroleptic malignant syndrome happen?

NMS happens due to blockage of dopamine receptors. Dopamine is a chemical messenger that helps convey messages between cells. It's believed that drugs associated with NMS block dopamine receptors in the brain, leading to NMS symptoms. Although severe, NMS is rare.

Which of the following increases the risk for neuroleptic malignant syndrome NMS )?

One of the clearest risk factors in the development of NMS is the course of drug therapy chosen to treat a condition. Use of high-potency neuroleptics, a rapid increase in the dosage of neuroleptics, and use of long-acting forms of neuroleptics are all known to increase the risk of developing NMS.

What do neuroleptic drugs do?

Neuroleptics, also known as antipsychotic medications, are used to treat and manage symptoms of many psychiatric disorders. They fall into two classes: first-generation or "typical" antipsychotics and second-generation or "atypical" antipsychotics." Neuroleptic drugs block dopamine receptors in the nervous system.

Can Lamictal cause NMS?

NMS is caused mainly by typical antipsychotic drugs (TAPDs), but reports of AAPD (aripiprazole, quetiapine, olanzapine or risperidone) in- duced NMS are well documented [5]. So far, only two cases of NMS induced by lamotrigine and antipsy- chotics such as aripiprazole and risperidone have been reported [6, 7].

• Stop all neuroleptics.
• Correct volume depletion and hypotension with intravenous fluids.
• Reduce hyperthermia.

4. Blood urea nitrogen (BUN) and creatinine levels.
5. Calcium and phosphate levels.
