What are the signs and symptoms of neuroleptic malignant syndrome?
Sarah Marsh What are the signs and symptoms of neuroleptic malignant syndrome?
Symptoms of neuroleptic malignant syndrome usually include very high fever (102 to 104 degrees F), irregular pulse, accelerated heartbeat (tachycardia), increased rate of respiration (tachypnea), muscle rigidity, altered mental status, autonomic nervous system dysfunction resulting in high or low blood pressure.
What is the cause of 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.
Is neuroleptic malignant syndrome a extrapyramidal symptoms?
Antipsychotic medications commonly produce extrapyramidal symptoms as side effects. The extrapyramidal symptoms include acute dyskinesias and dystonic reactions, tardive dyskinesia, Parkinsonism, akinesia, akathisia, and neuroleptic malignant syndrome.
Which increases the risk for neuroleptic malignant syndrome NMS?
Risk factors The main risk factor for developing NMS is taking antipsychotic medication. While some more potent drugs may increase a person’s risk, all antipsychotic medications can cause this condition. Taking more than one antipsychotic drug can also increase a person’s risk of developing NMS.
What should the nurse do if neuroleptic malignant syndrome occurs?
Treatment of patients with neuroleptic malignant syndrome may include the following:
- Benzodiazepines for restraint may be useful.
- Stop all neuroleptics.
- Correct volume depletion and hypotension with intravenous fluids.
- Reduce hyperthermia.
How long does neuroleptic malignant syndrome last?
In patients who develop neuroleptic malignant syndrome after taking an oral agent, the syndrome may last 7-10 days after discontinuation of the drug. In those who have received depot neuroleptics (eg, fluphenazine), the syndrome may last up to a month.
How do you reverse neuroleptic malignant syndrome?
The symptoms reverse with reinstitution of therapy, and benzodiazepines may be helpful. A central anticholinergic syndrome most often associated with intended or inadvertent drug overdose is better known. Patients present with encephalopathy and elevated body temperatures that are usually not as severe as NMS.
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.
How do you manage a patient who develops neuroleptic malignant syndrome?
Treatment of patients with neuroleptic malignant syndrome may include the following:
- Benzodiazepines for restraint may be useful.
- Stop all neuroleptics.
- Correct volume depletion and hypotension with intravenous fluids.
- Reduce hyperthermia.
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.
Do antipsychotics ruin your brain?
The evidence shows, she says, that antipsychotics not only do not work long-term they also cause brain damage – a fact which is being “fatally” overlooked. Plus, because of a cocktail of vicious side-effects, antipsychotics almost triple a person’s risk of dying prematurely.
What is the history of neuroleptic malignant syndrome?
Background. 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. The first reported case of NMS appeared in 1956, shortly after the introduction of the antipsychotic drug chlorpromazine (thorazine).
What is neuroneuroleptic malignant syndrome (NMS)?
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. The first reported case of NMS appeared in 1956, shortly after the introduction of the antipsychotic drug chlorpromazine (thorazine).
How can we reduce mortality rates of neuroleptic malignant syndrome?
Maintaining vigilant awareness of the clinical features of NMS to diagnose and treat the disorder early, however, remains the most important strategy by which physicians can keep mortality rates low and improve patient outcomes.

Do atypical neuroleptics increase the risk of non-specific malignant seizures (NMS)?
Although atypical neuroleptics appear to have reduced the risk of developing NMS compared to typical neuroleptics,10a significant number of cases have been reported with most atypical neuroleptics including risperidone,16clozapine,17quetiapine,18olanzapine,19ariprazole]
