Recent studies have indicated that Risperdal may cause neuroleptic malignant syndrome, a potentially fatal neurological disorder. In the vast majority of cases, the higher the dose, the greater the likelihood the patient will develop the syndrome. Neuroleptic malignant syndrome usually develops shortly after starting Risperdal, but it may occur at any time during treatment.

Incidence & Demographics
Antipsychotic medications first came to be associated with neuroleptic malignant syndrome (NMS) during the 1950s. The term comes from the French “syndrome malin des neuroleptiques.” A large number of cases of NMS have been reported over the past half-century, and similar disorders that were described by other names in the medical literature may have actually been neuroleptic malignant syndrome.
NMS occurs in people of all ages, and about twice as often in men as in women. Most cases occur in patients between the ages of 20 and 50, which likely coincides with the age groups most likely to be prescribed antipsychotics. In most cases, patients with NMS have a history of neuroleptic treatment. Along with Risperdal, other drugs linked to neuroleptic malignant syndrome include clozapine and olanzapine.
Neuroleptic Malignant Syndrome Symptoms
Risperdal users with neuroleptic malignant syndrome typically suffer from varying degrees of the following symptoms:
- Muscle rigidity
- Altered consciousness
- Autonomic dysfunction
In many cases, muscle rigidity that does not respond to treatment may be the 1st symptom of neuroleptic malignant syndrome. Rigidity may range from moderate to severe, “lead-pipe” rigidity. Parkinsonian symptoms are often found in patients with NMS, and a number of other movement disorders may accompany the condition as well.
Altered consciousness may range from decreased awareness to total confusion and unresponsiveness. Other mental conditions such as agitation or delirium are also commonly reported. Autonomic dysfunction typically manifests as hypertension, postural hypotension, unusual blood pressure fluctuation, tachycardia and/or tachypnea.
As we have seen, one of the most significant risk factors for the development of neuroleptic malignant syndrome is the use of Risperdal. High dosages, rapid increase in dose, and long-term treatment with Risperdal may all increase the risk of the condition.
