Chorea is a neurological condition characterized by involuntary, irregular muscle movements that are brief, non-repetitive, and unpredictable. This disorder affects the body's motor functions, leading to fluid and dance-like movements that can impact various parts of the body. Chorea is notably associated with [[Huntington's disease]], but it can also arise from a variety of other conditions. | Chorea is a neurological condition characterized by involuntary, irregular muscle movements that are brief, non-repetitive, and unpredictable.

Chorea[edit]
Chorea is a neurological condition characterized by involuntary, irregular muscle movements that are brief, non-repetitive, and unpredictable. This disorder affects the body's motor functions, leading to fluid and dance-like movements that can impact various parts of the body. Chorea is notably associated with Huntington's disease, but it can also arise from a variety of other conditions.
Causes[edit]
Chorea can be caused by several factors, including:
- Genetic disorders, with Huntington's disease being the most well-known cause.
- Autoimmune diseases, such as Sydenham's chorea, which is associated with rheumatic fever.
- Metabolic disorders.
- Drug-induced chorea, resulting from the side effects of certain medications.
- Infections and other conditions affecting the brain.
Symptoms[edit]
Symptoms of chorea include:
- Involuntary movements that are rapid, jerky, and unpredictable.
- Muscle weakness and coordination problems.
- Difficulty maintaining posture and balance.
- Changes in gait and facial expressions.
Diagnosis[edit]
Diagnosis of chorea involves:
- Clinical evaluation of the symptoms.
- Neurological examination.
- Genetic testing, especially for conditions like Huntington's disease.
- Imaging studies, such as MRI or CT scans, to observe brain structure and function.
- Blood tests to identify possible metabolic or autoimmune causes.
Treatment[edit]
While there is no cure for chorea, treatment focuses on managing symptoms and may include:
- Medications to reduce involuntary movements, such as antipsychotics or benzodiazepines.
- Therapies to improve motor skills and manage physical symptoms.
- Supportive care for emotional and psychological well-being.
Association with Huntington's Disease[edit]
Huntington's disease is a genetic disorder that leads to the progressive degeneration of nerve cells in the brain. Chorea is a hallmark symptom of Huntington's, along with cognitive decline and psychiatric issues. Understanding and managing chorea is crucial in the overall care for patients with Huntington's disease.
