How does neuroleptic malignant syndrome happen?
What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is a severe disorder caused by an adverse reaction to medications with dopamine receptor-antagonist properties or the rapid withdrawal of dopaminergic medications.
What is the best treatment for NMS?
In more severe cases of NMS, empiric pharmacologic therapy is typically tried. The two most frequently used medications are bromocriptine mesylate, a dopamine agonist, and dantrolene sodium, a muscle relaxant that works by inhibiting calcium release from the sarcoplasmic reticulum.
What is the next step in the management of NMS?
The next key step in the management of NMS is the initiation of supportive medical therapy. Aggressive hydration is often required, especially if highly elevated CPK levels threaten to damage the kidneys, and treatment of hyperthermia with cooling blankets or ice packs to the axillae and groin may be needed.
Which neuroleptic drug is most commonly associated with NMS?
Potent typical neuroleptics such as haloperidol, fluphenazine, chlorpromazine, trifluoperazine, and prochlorperazine have been most frequently associated with NMS and thought to confer the greatest risk.
How long does it take for a person to develop NMS?
The diagnosis of NMS is based on history and the presence of certain physical examination and laboratory findings.5,6Patients 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.7Although NMS has classically been characterized by the presence of the triad of fever, muscle rigidity, and altered mental status, its presentation can be quite heterogeneous, as reflected in the current Diagnostic and Statistical Manual of Mental Disorders(Fourth Edition [DSM-IV] criteria (see Table 1).8The clinical course typically begins with muscle rigidity followed by a fever within several hours of onset and mental status changes that can range from mild drowsiness, agitation, or confusion to a severe delirium or coma.
What are the laboratory findings of NMS?
Characteristic laboratory findings seen in NMS include elevated creatinine phosphokinase (CPK) due to rhabdomyolysis and leukocytosis, but these are neither specific for the syndrome nor present in all cases.14When rhabdomyolysis is present, it can be severe enough to cause renal failure, requiring hemodialysis.13Additional common laboratory abnormalities include a metabolic acidosis and iron deficiency.15The cerebrospinal fluid (CSF) and imaging studies are usually normal, but an electroencephalogram (EEG) may show nongeneralized slowing.7
What are the hallmarks of a CNS infection?
In addition to fever and mental status changes, hallmarks of a CNS infection include a history of prodromal illness, headaches, meningeal signs, focal neurological signs, seizures, and frequently positive CSF and neuroimaging studies.
What is neuroleptic malignant syndrome?
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.
What are neuroleptic medications?
neuroleptic medications under a doctor's supervision, immediate measures to restore appropriate water and nutrient levels, and steps to lower the individual's body temperature. Medications prescribed as treatment may include skeletal muscle relaxants, such as dantrolene; stimulators of dopamine production and activity, such as bromocriptine; and/or continuous perfusion of central nervous system depressants, such as diazepam.
Can neuroleptic malignant syndrome affect men?
Neuroleptic malignant syndrome may affect any person taking neuroleptic drugs. Men appear to be at higher risk than women. Some clinicians believe that the stronger neuroleptic medications are more likely to precipitate an attack of NMS.
Can NMS recur?
Recurrence of an attack of NMS is not uncommon. The risk of recurrence is closely related to the time elapsed between the end of the original episode of neuroleptic malignant syndrome and the beginning of renewed administration of an antipsychotic drug. If the waiting period is two weeks or less, about 63% will have a recurrence.
Can neuroleptic malignant syndrome be treated with electroconvulsive therapy?
Such patients must be carefully monitored since recurrences of neuroleptic malignant syndrome are not infrequent. Electroconvulsive treatments have been prescribed for patients with neuroleptic malignant syndrome with varied results.
What is the treatment for neuroleptic malignant syndrome?
Treatment of neuroleptic malignant syndrome (NMS) is mainly supportive; it is directed toward controlling the rigidity and hyperthermia and preventing complications ( eg, respiratory failure, renal failure). Monitoring and management in an intensive care unit (ICU) is recommended.
How to identify possible precipitants of neuroleptic malignant syndrome?
To identify possible precipitants of neuroleptic malignant syndrome, prehospital personnel should try to obtain an accurate medication list. If that is impossible, they should bring all the medication bottles found with the patient.
How does dantrolene sodium help with neuroleptic malignant syndrome?
Dantrolene sodium directly relaxes muscles by inhibiting calcium release from the sarcoplasmic reticulum. Most patients respond to 400 mg/day or less.
What is electroconvulsive therapy?
In patients with neuroleptic malignant syndrome, electroconvulsive therapy (ECT) can help with the alteration of temperature, level of consciousness, and diaphoresis. It may also be useful in treating the underlying psychiatric disease in patients who are unable to take neuroleptics. [ 44, 45] A retrospective case series of 15 patients with refractory NMS who were treated with ECT over a 17-year period reported a remission rate of 73.3%. Although early response occurred after a mean of 4.2 treatments, an average of 17.7 treatments were needed to keep catatonic signs from recurring. [ 46]
How long does it take for neurologic deficits to resolve?
No new focal neurologic deficits should develop, although cases of neurologic sequelae have been reported rarely. In most cases, symptoms will resolve in 1-2 weeks.
Can neuroleptic malignant syndrome be prolonged?
Neuroleptic malignant syndrome may be prolonged. If the patient is discharged, close follow-up care should be given to monitor residual symptoms. The patient's psychiatric disease must be evaluated and treated during withdrawal of the neuroleptic medication.
What is bromocriptine used for?
Bromocriptine is a dopamine agonist that overcomes neuroleptic-induced dopaminergic blockade. It has also been used in combination with dantrolene, but studies have questioned the benefit of this approach. [ 50, 49]
What causes neuroleptic malignant syndrome?
NMS happens when dopamine levels in the brain drop quickly. Dopamine plays an important role in controlling:
What medications are associated with neuroleptic malignant syndrome?
Several medications can lead to NMS, including certain antipsychotic and antidepressant medications. It’s important to remember that NMS is rare. It’s good to be aware of NMS, but don’t stop your medication without talking to your healthcare provider. It’s very likely that your medication’s benefits far outweigh your risk of developing NMS.
What can you do to lower your risk?
It’s unclear why some people get NMS and others don’t — even if they use the same medication.
The bottom line
Neuroleptic malignant syndrome is a rare but serious condition that can cause damage to the heart, brain, and lungs. NMS develops in some people who take medications that lower the amount of dopamine in the brain. Certain types of antipsychotics and antidepressants are more likely to cause NMS than others.
