• Focus on antibody-related movement disorders.

Main Methods:

• Literature review of recent studies on neuronal antibodies.
• Analysis of clinical presentations and pathophysiological insights.

Main Results:

• Phosphodiesterase 10A antibodies linked to paraneoplastic chorea.
• mGluR5 antibodies associated with hyperkinetic disorders and Ophelia syndrome.
• Kelch-like protein 11 antibodies common in paraneoplastic cerebellar ataxia.

Conclusions:

• New antibody markers are crucial for identifying patients for immunotherapy.
• Understanding pathophysiology can guide personalized treatment strategies.
