RESULTS: Anti-IgLON5 is a heterogenous neurodegenerative and autoimmune disease manifested by a variety of signs and symptoms including sleep disorder, bulbar dysfunction, movement disorder, cognitive impairment, and autonomic dysfunction. CONCLUSIONS AND IMPORTANCE: Eye movement disturbances (e.g., nystagmus, gaze palsy, slow saccadic velocities) can be a prominent clinical feature of anti-IgLON5 disease.
