What is neuroleptic sensitivity?

Severe neuroleptic sensitivity affects up to 50% of the LBD patients who are treated with traditional antipsychotic medications, and is characterized by worsening cognition, sedation, increased or possibly irreversible acute onset parkinsonism, or symptoms resembling neuroleptic malignant syndrome, which can be fatal.

Which dementia type is hypersensitive to neuroleptics?

Neuroleptic hypersensitivity is characteristic of dementia with Lewy bodies (DLB) but not of other dementias. The authors report 5 patients with psychotic mood disorders and long-standing antipsychotic drug therapy.

Is risperidone used for Lewy body dementia?

Allen et al. 10 described 3 patients with Lewy body dementia who were treated with risperidone 0.5 mg once or twice daily. All 3 pa- tients experienced significant reductions in psychosis and agitation. Risperidone was well tolerated, with no decline in cognitive function noted.

What is antipsychotic hypersensitivity?

Hypersensitivity to typical neuroleptics and the newer antipsychotics may range from extrapyramidal rigidity to partial or forme fruste NMS or the entire NMS with severe rigidity, delirium, fever, muteness or hypophonia, autonomic changes, elevated white count, and CPK levels greater than 300 IU.

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.

Does Lewy body dementia cause psychosis?

Prominent psychotic symptoms, particularly hallucinations and delusions, have been estimated to occur in approximately 60% of patients with dementia with Lewy bodies (DLB). Many of these individuals experience psychotic symptoms before the onset of other features characteristic of DLB.

What drugs should be avoided with Lewy body dementia?

If possible, avoid medications with anticholinergic properties, which can worsen cognition, or dopamine agonists, which can cause hallucinations. First-generation antipsychotic medications, such as haloperidol (Haldol), should not be used to treat Lewy body dementia.

Does b12 deficiency cause dementia?

Cobalamin deficiency has been shown to be the most frequent associated physical disease in patients with dementia. The incidence of low vitamin B12 levels among dementia patients has been found to range between 29%8 and 47%.

Why do you avoid antipsychotics in Lewy body dementia?

Neuroleptic drugs, especially older agents, should be avoided in patients who have dementia with Lewy bodies because they may cause severe reactions in more than one half of these patients and are associated with increased mortality.

What is another term for social phobia?

Social anxiety disorder (also called social phobia) is a mental health condition. It is an intense, persistent fear of being watched and judged by others.

Can a person with dementia be sensitive to neuroleptic agents?

Background: Severe sensitivity to neuroleptic agents is a major clinical problem in dementia with Lewy bodies (DLB), but has not been determined in Parkinson’s disease (PD) and PD with dementia (PDD).

How are severe neuroleptic sensitivity reactions ( NSRS ) evaluated?

Method: Severe neuroleptic sensitivity reactions (NSRs) were evaluated according to an operationalized definition blind to clinical and neuropathologic diagnoses in prospectively studied patients exposed to neuroleptics from 2 centers. The study was conducted from June 1995 to May 2003.

What do you need to know about neuroleptic malignant syndrome?

Related Information. Neuroleptic malignant syndrome is a life-threatening, neurological disorder most often caused by an adverse reaction to neuroleptic or antipsychotic drugs.

Which is the most potent neuroleptic in the world?

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.
