[Ballism in systemic lupus erythematosus].

Area of Science:

• Neurology
• Rheumatology
• Systemic Lupus Erythematosus (SLE)

Background:

• Systemic lupus erythematosus (SLE) is a complex autoimmune disease with diverse neurological and psychiatric manifestations.
• Central nervous system (CNS) involvement in SLE accounts for a significant portion of patient morbidity.
• Movement disorders, though rare, represent a distinct category of neuro-SLE manifestations.

Observation:

• This case report details a patient presenting with ballism, a hyperkinetic movement disorder characterized by violent, flinging limb movements.
• Ballism was the presenting symptom, preceding the formal diagnosis of SLE.
• The occurrence of ballism in this context underscores the varied clinical presentations of neuro-SLE.

Findings:

• Movement disorders, including ballism, constitute approximately 2% of CNS manifestations in SLE.
• These movement disorders frequently precede other neuro-psychiatric symptoms and the eventual SLE diagnosis.
• Current diagnostic criteria for SLE, such as the 1982 revised American Rheumatism Association criteria, do not explicitly include ballism or other rare movement disorders.

Implications:

• The presentation of ballism warrants a high index of suspicion for underlying SLE.
• Awareness of the association between CNS disease and severe SLE is crucial for timely diagnosis and management.
• Therapeutic interventions for SLE should be critically assessed, considering the potential for severe neurological involvement.
