INTRODUCTION Neuroleptic malignant syndrome (NMS) is a life-threatening neurologic emergency associated with the use of antipsychotic (neuroleptic) agents and characterized by a distinctive clinical syndrome of mental status change, rigidity, fever, and dysautonomia.

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.

Can NMS cause brain damage?

The primary morbidity and mortality associated with NMS are irreversible brain injury from hyperthermia and renal failure from myoglobinuria secondary to rigidity-induced skeletal muscle necrosis. Neuroleptics are commonly prescribed drugs in the United States.

How common is NMS?

Neuroleptic malignant syndrome (NMS) is rare. Approximately 0.01% to 3.2% of people taking neuroleptic (antipsychotic) medications develop NMS. Cases have been decreasing due to newer medications that are less likely to cause NMS and increased awareness of the syndrome.

What causes NMS syndrome?

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.

What is NMS in medical terms?

A life-threatening condition that may be caused by certain drugs used to treat mental illness, nausea, or vomiting. Symptoms include high fever, sweating, unstable blood pressure, confusion, and stiffness. Also called neuroleptic malignant syndrome.

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 long does NMS take to develop?

Patients typically develop NMS within hours or days after exposure to a causative drug, with most exhibiting symptoms within 2 weeks and nearly all within 30 days.

How is neuroleptic malignant diagnosed?

The diagnosis is confirmed by the presence of recent treatment with neuroleptics (within the past 1-4 weeks), hyperthermia (temperature above 38°C), and muscular rigidity, along with at least five of the following features: Change in mental status. Tachycardia. Hypertension or hypotension.

Can antidepressants cause NMS?

An antidepressant-induced NMS is a very rare complication on the basis of pretreatment with neuroleptics causing chronic dopamine blockade and elevated plasma level of neuroleptics due to comedicated antidepressants.

What are the features of NMS?

Features which distinguish NMS from serotonin syndrome include bradykinesia, muscle rigidity, and a high white blood cell count.

How to treat NMS?

The first step is to stop the antipsychotic medication and treat the hyperthermia aggressively, such as with cooling blankets or ice packs to the axillae and groin. Supportive care in an intensive care unit capable of circulatory and ventilatory support is crucial. The best pharmacological treatment is still unclear. Dantrolene has been used when needed to reduce muscle rigidity, and more recently dopamine pathway medications such as bromocriptine have shown benefit. Amantadine is another treatment option due to its dopaminergic and anticholinergic effects. Apomorphine may be used however its use is supported by little evidence. Benzodiazepines may be used to control agitation. Highly elevated blood myoglobin levels can result in kidney damage, therefore aggressive intravenous hydration with diuresis may be required. When recognized early NMS can be successfully managed; however, up to 10% of cases can be fatal.

How long does neuroleptic malignant syndrome last?

The first symptoms of neuroleptic malignant syndrome are usually muscle cramps and tremors, fever, symptoms of autonomic nervous system instability such as unstable blood pressure, and sudden changes in mental status (agitation, delirium, or coma ). Once symptoms appear, they may progress rapidly and reach peak intensity in as little as three days. These symptoms can last anywhere from eight hours to forty days.

When was NMS first discovered?

NMS was known about as early as 1956, shortly after the introduction of the first phenothiazines.

They characterized the condition that was associated with the side effects of haloperidol " syndrome malin des neuroleptiques ", which was translated to neuroleptic malignant syndrome.

Why is creatine phosphokinase elevated in NMS?

The raised white blood cell count and creatine phosphokinase (CPK) plasma concentration seen in those with NMS is due to increased muscular activity and rhabdomyolysis (destruction of muscle tissue). The patient may suffer hypertensive crisis and metabolic acidosis. A non-generalized slowing on an EEG is reported in around 50% of cases.

Can NMS be delayed?

Symptoms are sometimes misinterpreted by doctors as symptoms of mental illness which can result in delayed treatment. NMS is less likely if a person has previously been stable for a period of time on antipsychotics, especially in situations where the dose has not been changed and there are no issues of noncompliance or consumption of psychoactive substances known to worsen psychosis.

While symptoms usually develop during the first two weeks of antipsychotic therapy, the association of the syndrome with drug use is idiosyncratic. NMS can occur after a single dose or after treatment with the same agent at the same dose for many years [ 14 ].

What are the risk factors for NMS?

Associated risk factors — Case series and case-control studies also suggest that certain psychiatric conditions, acute catatonia, and extreme agitation are over-represented in patients who develop NMS [ 4,15-17 ]. It is possible that these represent conditions of higher risk simply because of the increased use of higher doses, rapid escalation, and parenteral therapy.

What is the role of dopamine receptor blockade in NMS?

Central dopamine receptor blockade in the hypothalamus may cause hyperthermia and other signs of dysautonomia [ 31,32 ]. Interference with nigrostriatal dopamine pathways may lead to parkinsonian-type symptoms such as rigidity and tremor [ 18,32 ]. Other neurotransmitter systems (gamma aminobutyric acid, epinephrine, serotonin, and acetylcholine) also appear to be involved, either directly or indirectly [ 29,33 ].

Overview

Causes

NMS is usually caused by antipsychotic drug use, and a wide range of drugs can result in NMS. Individuals using butyrophenones (such as haloperidol and droperidol) or phenothiazines (such as promethazine and chlorpromazine) are reported to be at greatest risk. However, various atypical antipsychotics such as clozapine, olanzapine, risperidone, quetiapine, and ziprasidone have also been implicated in cases.
