Chorea Gravidarum: A Rare Movement Disorder During Pregnancy

Chorea gravidarum, also known as pregnancy-related chorea, is a rare movement disorder that can occur during pregnancy. It is characterized by involuntary, abrupt, and brief movements of any limb, often accompanied by non-patterned facial grimaces.

Symptoms and Characteristics

• Involuntary movements: Chorea gravidarum is marked by sudden, brief, and non-repetitive movements of any limb, which can be quite unpredictable.
• Non-rhythmic and non-repetitive: These movements are not rhythmic or repetitive, making them distinct from other movement disorders.
• Abrupt and brief: The movements associated with chorea gravidarum are abrupt and brief, lasting only for a short period.
• Facial grimaces: In many cases, chorea gravidarum is accompanied by non-patterned facial grimaces.

Causes and Associations

• Pregnancy-related: Chorea gravidarum is directly related to pregnancy and can be associated with eclampsia.
• Rare complication: This movement disorder is a rare complication of pregnancy, affecting approximately 1 in 2,000 to 3,000 pregnancies.
• Other associations: Chorea gravidarum has been linked to rheumatic fever, collagen vascular disorders, and other conditions.

Treatment and Resolution

• Spontaneous resolution: In some cases, chorea gravidarum can spontaneously resolve before delivery or after delivery in up to one-third of cases.
• Complete resolution: Despite complete resolution, chorea can occur again during pregnancy in up to 75% of patients who have had rheumatic fever resulting in chorea.

Common Signs and Symptoms of Chorea Gravidarum

Chorea gravidarum, a rare movement disorder that occurs during pregnancy, presents with various symptoms that can affect the overall well-being of the mother. The following are some common signs and symptoms associated with chorea gravidarum:

• Involuntary movements: Sudden, brief, non-rhythmic movements affecting the limbs, face, and trunk [4][10]
• Difficulty swallowing: Muscle contractions without a regular rhythm can make it challenging to swallow food and liquids [8]
• Speech difficulties: Abnormal speech patterns, such as stuttering or slurred words, may be experienced by some women with chorea gravidarum [8]
• Abnormal walk: Unsteady gait or difficulty walking due to involuntary movements [8]
• Personality changes: Some women may experience mood swings, depression, or anxiety related to their condition [7]
• Cognitive deficits: In rare cases, chorea gravidarum can lead to chronic cognitive impairments, affecting memory and concentration [7]

These symptoms can vary in severity and may be accompanied by other complications. It's essential for pregnant women experiencing any of these symptoms to consult with their healthcare provider for proper evaluation and treatment.

Diagnostic Tests for Chorea Gravidarum

Chorea gravidarum, a rare movement disorder that occurs during pregnancy, can be challenging to diagnose. However, various diagnostic tests can help confirm the condition and rule out other potential causes.

• Physical Examination: A thorough physical examination is essential in diagnosing chorea gravidarum. The doctor will assess the patient's symptoms, medical history, and perform a neurological examination to identify any abnormalities.
• Medical History: Taking a detailed medical history is crucial in understanding the patient's symptoms and identifying potential causes of chorea gravidarum. This includes asking about previous pregnancies, medical conditions, and family history.
• Imaging Studies: Imaging studies such as MRI scans of the brain can help confirm the diagnosis of chorea gravidarum and rule out other potential causes such as a brain tumor or Huntington's disease [1].
• Genetic Testing: Genetic testing may be recommended to identify any genetic mutations that could be contributing to the condition. This is particularly important if there is a family history of chorea gravidarum or other neurodegenerative disorders [2].
• Blood Tests: Blood tests can help rule out other potential causes of chorea gravidarum such as thyroid dysfunction, anemia, or clotting disorders [3].

Investigations for Chorea Gravidarum

The diagnostic approach for chorea gravidarum involves a combination of the following investigations:

• MRI scan of the brain
• Genetic testing to identify any genetic mutations
• Blood tests to rule out other potential causes
• Physical examination and medical history

Early diagnosis and treatment of chorea gravidarum are essential in ensuring good maternal and fetal outcomes [4].

Treatment Options for Chorea Gravidarum

Chorea gravidarum, a rare movement disorder that occurs during pregnancy, can be effectively managed with drug treatment. The primary goal of treatment is to alleviate symptoms and prevent complications.

• Haloperidol: This potent dopamine antagonist is often considered the first-line agent for treating chorea gravidarum. Studies have shown its effectiveness in reducing severe disabling chorea [2][8]. A starting dose of 2–6 mg/day up to 20 mg/day may be prescribed, with careful monitoring of side effects [2].
• Pimozide: This neuroleptic drug is another option for treating chorea gravidarum. It carries lesser adverse effects than haloperidol and can provide effective relief from symptoms [15].

Other Treatment Considerations

While these medications are commonly used to treat chorea gravidarum, it's essential to consider the teratogenic risks to the fetus when choosing a treatment plan. A doctor may prescribe medications if you have severe symptoms or if the fetus is at risk of malnutrition or dehydration [12]. In some cases, anticonvulsants may also be used to manage chorea outside of pregnancy [12].

Chorea gravidarum, also known as pregnancy-related chorea or Puerperal chorea, is a rare neuropsychiatric disorder that occurs in some pregnant women. The differential diagnosis for chorea gravidarum involves considering various conditions that can cause similar symptoms. Here are some possible causes:

1. Huntington's disease: Although rare, Huntington's disease can be triggered or exacerbated by pregnancy.
2. Sydenham's chorea: This is an autoimmune disorder that can cause chorea and other neuropsychiatric symptoms in children and adults.
3. Systemic lupus erythematosus (SLE): SLE is a chronic autoimmune disease that can cause chorea, among other symptoms.
4. Multiple sclerosis: In rare cases, multiple sclerosis can present with chorea-like symptoms.
5. Wilson's disease: This genetic disorder causes copper accumulation in the body and can lead to neuropsychiatric symptoms, including chorea.
6. Pregnancy-related autoimmune disorders: Some women may experience autoimmune disorders during pregnancy, such as antiphospholipid syndrome or lupus, which can cause chorea-like symptoms.
7. Medication-induced chorea: Certain medications, like anticonvulsants or antidepressants, can cause chorea as a side effect.
8. Neuroacanthocytosis: This is a rare genetic disorder that can cause chorea and other neuropsychiatric symptoms.
9. Pantothenate kinase-associated neurodegeneration (PKAN): PKAN is a rare genetic disorder that can cause chorea, among other symptoms.

To diagnose chorea gravidarum accurately, healthcare providers should consider the following:

• A thorough medical history, including any previous pregnancies and medical conditions
• Physical examination to rule out other potential causes of chorea
• Laboratory tests, such as blood work and imaging studies (e.g., MRI or CT scans), to evaluate for underlying conditions
• Consultation with specialists, like neurologists or rheumatologists, if necessary

Early recognition and diagnosis are crucial to provide appropriate treatment and management for the patient.
