[Severe choreiform movement disorder following COVID-19]

Area of Science:

• Neurology
• Infectious Diseases
• Movement Disorders

Background:

• COVID-19, caused by SARS-CoV-2, primarily impacts cardiovascular and respiratory systems.
• Increasing reports link SARS-CoV-2 infection to diverse neurological symptoms.
• Post-infectious neurological complications require further investigation.

Purpose of the Study:

• To report a case of choreiform gait disturbance following SARS-CoV-2 infection.
• To explore the potential pathogenesis of chorea post-COVID-19.
• To provide an overview of neurological movement disorders associated with COVID-19.

Main Methods:

• Case report of a 54-year-old male patient.
• Clinical observation of neurological symptoms, specifically gait disturbance.
• Literature review on COVID-19 associated neurological and movement disorders.

Main Results:

• The patient presented with significant choreiform gait disturbance approximately three months after a severe symptomatic SARS-CoV-2 infection.
• The case highlights a delayed onset of neurological sequelae.
• Discussion includes potential etiological factors for chorea.

Conclusions:

• SARS-CoV-2 infection can lead to delayed-onset neurological complications, including movement disorders like chorea.
• Understanding the pathogenesis of these disorders is crucial for patient management.
• Further research is needed to elucidate the mechanisms behind post-COVID-19 neurological manifestations.
