Neuroleptic malignant syndrome (NMS) is a rare [5] [6] but life-threatening reaction that can occur in response to antipsychotics (neuroleptic) or other drugs that block the effects of dopamine. [ 1 ] [ 7 ] Symptoms include high fever , confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. [ 1 ]
The recovery process from anti-NMDAR encephalitis can take many months depending on its form and severity. The symptoms may reappear in reverse order: The patient may begin to experience psychosis again, leading many people to falsely believe the patient is not recovering. As the recovery process continues on, the psychosis fades.
Risperidone (atypical) has a similar rate of extrapyramidal symptoms to haloperidol (typical). [110] A rare but potentially lethal condition of neuroleptic malignant syndrome (NMS) has been associated with the use of antipsychotics. Through its early recognition, and timely intervention rates have declined.
This is a general list of long-term side effects associated with Antipsychotic (neuroleptic) medication.. Many patients will not develop these side effects, although there is still a significant possibility of risks associated with Antipsychotic usage.
These mothers require sedation with anti-psychotic (neuroleptic) agents, but are liable to extrapyramidal symptoms, [51]: 228 including neuroleptic malignant syndrome. [90] Since the link with bipolar disorder was recognized (about 1970), treatment with mood-stabilizing agents, such as lithium [ 72 ] : 20–23 and anti-convulsant drugs, has ...
People with Lewy body dementias who take neuroleptics are at risk for neuroleptic malignant syndrome, a life-threatening illness. [51] There is no evidence to support the use of antipsychotics to treat the Lewy body dementias, [10] and they carry the additional risk of stroke when used in the elderly with dementia. [86]
Antipsychotic medications may cause neuroleptic malignant syndrome, which can cause severe muscle rigidity with rhabdomyolysis and hyperpyrexia; Neuromuscular blocking agents used in anesthesia may result in malignant hyperthermia, also associated with rhabdomyolysis; Medications that cause serotonin syndrome, such as SSRIs
The rise in core temperature is really hyperthermia due mostly to excessive muscle activity and not fever, although these two are frequently mixed up (even the mesh definition for Neuroleptic malignant syndrome says 'fever'). Maybe this should be changed, although the useful mnemonic would also need to be altered.
