According to studies, older, first-generation antipsychotics are associated with a significantly higher risk of developing tardive dyskinesia compared to newer, second-generation agents. Knowing which antipsychotic has the highest risk of tardive dyskinesia is crucial for both patients and healthcare providers to manage and mitigate this potentially irreversible movement disorder.

Approximately 20-50% of patients on long-term antipsychotic treatment, particularly older-generation drugs, have developed tardive dyskinesia (TD), a potentially irreversible side effect. This condition manifests as involuntary, repetitive movements and is a significant concern for those undergoing treatment with these vital medications.

Neuroleptic Malignant Syndrome (NMS) is a rare but life-threatening reaction to antipsychotic drugs, including haloperidol, with a reported mortality rate of around 10-15%. This severe adverse effect is a critical concern for both patients and healthcare providers, requiring prompt recognition and treatment. While uncommon, the potential for **haloperidol to cause NMS** is a known risk associated with its use.

While associated with a lower risk of movement disorders compared to older antipsychotics, some studies and clinical reports confirm that ziprasidone can indeed cause tremors. This involuntary muscle trembling or shaking is part of a category of motor side effects known as extrapyramidal symptoms (EPS).

In clinical trials, paliperidone use was associated with an incidence of parkinsonism that can range up to 18%, depending on the formulation and dosage, and is considered an extrapyramidal symptom. This article explores the important question, 'Does paliperidone cause Parkinson's disease?' to clarify the crucial medical distinction between the medication's potential side effects and the neurodegenerative disorder itself.

Yes, haloperidol is an antipsychotic medication, specifically classified as a first-generation or 'typical' antipsychotic. It is one of the most widely used antipsychotic drugs globally and is primarily used to treat schizophrenia and other psychotic disorders.
