Understanding Drug-Induced Chorea: Causes and Symptoms

Drug-induced chorea is a condition characterized by involuntary, irregular, and unpredictable movements of the body. It is a type of movement disorder that can be caused by certain medications or drugs. Although drug-induced chorea is relatively rare, it is essential to be aware of its causes and symptoms.

Causes:

1. Antipsychotic medications: Some antipsychotic drugs, such as haloperidol and risperidone, have been known to trigger drug-induced chorea.
2. Antiepileptic drugs: Certain antiepileptic medications, including phenytoin and carbamazepine, can induce chorea-like movements in some individuals.
3. Anti-nausea drugs: Metoclopramide, a commonly prescribed medication for nausea and vomiting, has been associated with drug-induced chorea.
4. Other medications: Various other drugs, such as some antidepressants, stimulants, and anti-HIV medications, have also been linked to the development of chorea-like symptoms.

Symptoms:

• Involuntary movements: The hallmark symptom of drug-induced chorea is the presence of involuntary, jerky, and uncontrolled movements, typically involving the arms, legs, and face.
• Restlessness: Individuals with drug-induced chorea often experience a sense of restlessness and an inability to sit or stand still.
• Impaired coordination: Chorea can affect coordination, making simple tasks like writing or eating challenging.
• Speech difficulties: Some people may have difficulty speaking clearly due to the irregular movements affecting the muscles involved in speech.
• Emotional and behavioral changes: In rare cases, drug-induced chorea may also lead to emotional instability, irritability, or changes in behavior.

It is important to note that drug-induced chorea is a reversible condition, meaning that once the causative medication is discontinued, the symptoms generally subside over time. However, it is crucial to consult with a healthcare professional if any unusual movements or symptoms occur after starting a new medication.

In conclusion, drug-induced chorea is a movement disorder that can occur as a side effect of certain medications. Recognizing the potential causes and symptoms of this condition is vital for early detection and appropriate management. If you suspect drug-induced chorea, consult your healthcare provider for a thorough evaluation and guidance.
