Horner syndrome is an eponym used to describe the clinical triad of ptosis, miosis, and anhidrosis caused by interruption of the ipsilateral first-, second-, or third-order sympathetic neurons to the head, eye, and neck. The hallmark of Horner syndrome is ptosis and miosis on the same side. When Horner syndrome is suspected, pharmacologic testing should be performed to confirm the diagnosis.

Acquired sensory neuronopathies depend on a primary involvement of sensory neurons in dorsal root ganglia leading eventually to a definitive and irreversible degeneration of the cell body. They include toxic, infectious, and dysimmune mechanisms, although an important proportion remains idiopathic after an extensive workup. The loss of large sensory neurons results in ataxia that usually predominates in the lower limbs, resulting in ataxic gate and Romberg sign.
