The pathogenesis and cause of neuroleptic malignant syndrome remain unclear. Malignant hyperthermia (MH) is an acute life-threatening hypermetabolic syndrome that occurs in susceptible individuals during exposure to inhalational anesthetic gases or the depolarizing neuromuscular blocker succinylcholine.

What is the difference between neuroleptic malignant syndrome and malignant hyperthermia?
Malignant hyperthermia — A rare genetic disorder, malignant hyperthermia (MH) is usually distinguished from NMS by its clinical setting: occurring with use of potent halogenated inhalational anesthetic agents and succinylcholine.
What is neuroleptic malignant like syndrome?
Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction to antipsychotic drugs characterized by fever, altered mental status, muscle rigidity, and autonomic dysfunction.
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.
What happens in neuroleptic malignant syndrome?
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.
What is another name for neuroleptic?
Antipsychotics, also known as neuroleptics, are a class of psychotropic medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia but also in a range of other psychotic disorders.
What is neuroleptic malignant syndrome symptoms?
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,
How do you diagnose neuroleptic malignant syndrome?
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.
How long does it take to recover from neuroleptic malignant syndrome?
NMS usually gets better in 1 to 2 weeks. After recovery, most people can start taking antipsychotic medicine again. Your doctor might switch you to a different drug.
Is NMS reversible?
The mortality rate of NMS is estimated to be as high as 20% and the usual cause of death is due to acute renal failure. Fortunately, with early recognition and intervention, it is usually reversible without any serious complications.
What can be mistaken for serotonin syndrome?
Neuroleptic Malignant Syndrome, which often times mimics serotonin syndrome, also develops over days to weeks [8,9]. Besides, in 70% of the patients, clinical signs including agitated delirium with confusion appear first, followed by tremors, rigidity, hyperthermia, profuse diaphoresis and tachypnoea [10-12].
Can SSRIs cause NMS?
SSRIs may cause NMS by their facilitative action on neurotransmitter serotonin along with central dopaminergic blockade. Addition of SSRI to second-generation antipsychotic is also reported to increase the risk of NMS by inhibiting dopamine release by SSRIs.
How do you remember serotonin syndrome symptoms?
The mnemonic MOIST can be used to remember the Hunter Criteria:
- M – Muscle rigidity, temperature >38°C, and either ocular clonus or inducible clonus.
- O – Ocular clonus and either agitation or diaphoresis.
- I – Inducible clonus and either agitation or diaphoresis.
- S – Spontaneous clonus.
- T – Tremor and hyperreflexia.
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.
What is EPS side effect?
Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain’s cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE).
What is neuroleptic exposure?
Neuroleptic-induced TD is characterized by choreiform, athetoid, and rhythmic movements of the tongue, jaw, trunk, and extremities that have persisted for at least 4 weeks and that began during treatment with neuroleptics or within 4 weeks of discontinuing neuroleptics.
