Argyll Robertson pupils, a clinical feature of neurosyphilis, are characterized by pupils that do not react to light but have an intact accommodation reflex. Another late form of neurosyphilis is general paresis, which is a slow degenerative process of the brain. Neuropsychiatric symptoms might appear due to overall damage to the brain.
