Abstract Details

Parkinsonism and Psychosis as the Only Initial Features of SLE in an Elderly Female - Case Report
Movement Disorders
P7 - Poster Session 7 (8:00 AM-9:00 AM)
17-005
To describe a rare case of neuropsychiatric systemic lupus erythematosus (SLE) presenting with acute-onset parkinsonism and psychosis in an elderly woman.
SLE is a multi-system autoimmune disease with diverse neuropsychiatric manifestations. While psychosis and certain movement disorders such as chorea are recognized but uncommon in SLE, parkinsonism is exceedingly rare. Diagnosing neuropsychiatric SLE presenting with parkinsonism is challenging due to its rarity and lack of confirmatory tests.

Not applicable

A 65-year-old female with comorbidities including HIV and breast cancer in remission presented with new-onset psychosis, characterized by paranoid delusions and auditory and visual hallucinations. Upon admission, she exhibited mild asymmetric resting tremor and speech hesitancy. Her neurological exam subsequently progressed to reveal marked parkinsonism, including bradykinesia, cogwheel rigidity, hypophonia, hypomimia, freezing of gait, and mutism, alongside persistent psychotic symptoms. There were no systemic symptoms or signs, such as skin or joint manifestations.

Extensive workup, including brain MRI and CSF analysis, ruled out metabolic, infectious, neoplastic, and structural causes. Dementia with Lewy bodies, drug-induced parkinsonism, leptomeningeal carcinomatosis, and autoimmune encephalitis were considered but excluded based on clinical course and serum and CSF studies. Serology revealed positive ANA, anti-Sm, and hypocomplementemia, leading to a diagnosis of neuropsychiatric SLE per 2019 EULAR/ACR criteria. Treatment with high-dose steroids, plasmapheresis, cyclophosphamide, and hydroxychloroquine resulted in resolution of both psychiatric and parkinsonian symptoms, with sustained remission at 6-month follow-up.
This case highlights the importance of considering secondary, reversible causes such as SLE when evaluating a patient who presents with acute-onset parkinsonism and psychosis, even in the absence of classic systemic features or rheumatologic history. Clinician vigilance for autoimmune etiologies enables timely immunomodulatory treatment, which can often result in full recovery.
