How does neuroleptic malignant syndrome affect the body?

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.

Can NMS cause brain damage?

Neuroleptic malignant syndrome (NMS) is a rare, but potentially lethal neurological emergency. Fifty percent of traumatic brain injury (TBI) patients will have emotional disorders and post-traumatic agitations.

What causes neuro malignant syndrome?

The primary trigger of NMS is dopamine receptor blockade and the standard causative agent is an antipsychotic. 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.

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.

Why do antipsychotics cause neuroleptic malignant syndrome?

The most widely accepted mechanism by which antipsychotics cause neuroleptic malignant syndrome is that of dopamine D2 receptor antagonism. In this model, central D2 receptor blockade in the hypothalamus, nigrostriatal pathways, and spinal cord leads to increased muscle rigidity and tremor via extrapyramidal pathways.

What are extrapyramidal side effects?

Extrapyramidal symptoms, also called drug-induced movement disorders, describe the side effects caused by certain antipsychotic and other drugs. These side effects include: involuntary or uncontrollable movements. tremors. muscle contractions.

Which of the following patients is most likely to have neuroleptic malignant syndrome?

Neuroleptic malignant syndrome has been reported to be more common in males, although that most likely reflects greater neuroleptic usage rather than greater susceptibility. The male-to-female ratio is 2:1.

Can Haldol cause neuroleptic malignant syndrome?

Any antipsychotic drug can cause NMS. But stronger drugs, like fluphenazine and haloperidol, are more likely to trigger it.

What does neuroleptic malignant syndrome mean?

Neuroleptic malignant syndrome (NMS) is a rare, but life-threatening, idiosyncratic reaction to neuroleptic medications that is characterized by fever, muscular rigidity, altered mental status, and autonomic dysfunction. NMS often occurs shortly after the initiation of neuroleptic treatment, or after dose increases.

How do antipsychotics cause extrapyramidal side effects?

Antipsychotics block dopamine, which is what causes the extrapyramidal side effects in the first place. Anticholinergics increase dopamine so it becomes leveled out in your system.

What is neuroleptic malignant syndrome?

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 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.
