Tabes dorsalis

These patients have lancinating nerve root pain which is aggravated by coughing, and features of sensory ataxia with ocular involvement.

Signs and symptoms may not appear for decades after the initial infection and include weakness, diminished reflexes, paresthesias (shooting and burning pains, pricking sensations, and formication), hypoesthesias (abnormally diminished sense of touch), tabetic gait (locomotor ataxia), progressive degeneration of the joints, loss of coordination, episodes of intense pain and disturbed sensation (including glossodynia), personality changes, urinary incontinence, dementia, deafness, visual impairment, positive Romberg's test, and impaired response to light (Argyll Robertson pupil).

A complication of tabes dorsalis can be transient neuralgic paroxysmal pain affecting the eyes and the ophthalmic areas, previously called "Pel's crises" after Dutch physician P.K.

[3] The spirochete invades large myelinated fibers, leading to the involvement of the dorsal column medial leminiscus pathway rather than the spinothalamic tract.
