Chorea is a neurological symptom characterized by involuntary, irregular, unpredictable, and jerky movements. Think of it as an unintentional "dance" affecting various body parts.
Key aspects of chorea:
- Involuntary Movements: These movements happen without conscious control.
- Irregular and Unpredictable: Unlike tremors or tics, the movements lack a rhythmic pattern and occur randomly.
- Location: Chorea can affect the face, limbs (arms and legs), and trunk.
- Appearance: The movements often appear fidgety, restless, or dance-like, which is why the term "chorea" comes from the Greek word for "dance."
Causes of Chorea:
Chorea is not a disease in itself but rather a symptom of an underlying condition. Some common causes include:
- Huntington's Disease: A hereditary neurodegenerative disorder.
- Sydenham's Chorea: A complication of rheumatic fever, primarily affecting children.
- Medications: Certain drugs, such as antipsychotics, can induce chorea.
- Other Conditions: Wilson's disease, stroke, autoimmune disorders, and infections can also cause chorea.
Diagnosis and Treatment:
Diagnosing the cause of chorea typically involves a neurological examination, medical history review, and possibly blood tests, imaging studies (like MRI), and genetic testing. Treatment focuses on managing the underlying condition and reducing the severity of the choreic movements. Medications may be prescribed to help control the involuntary movements.
In summary, chorea refers to the involuntary, jerky, and unpredictable movements often resembling a dance or fidgeting, and it's usually a symptom of an underlying medical condition that requires diagnosis and treatment.
