SpecialtyNeurology

Tabes dorsalis is a late consequence of

demyelination) of the neural tracts primarily in the dorsal root ganglia of the spinal cord
(nerve root). These patients have lancinating nerve root pain which is aggravated by coughing, and features of sensory ataxia with ocular involvement.

Signs and symptoms

Signs and symptoms may not appear for decades after the initial infection and include

"Tabes dorsalgia" is a related lancinating back pain.[citation needed]

"Tabetic gait" is a characteristic ataxic gait of untreated syphilis where the person's feet slap the ground as they strike the floor due to loss of proprioception. In daylight the person can avoid some unsteadiness by watching their own feet.[citation needed]

Cause

Tabes dorsalis is caused by

bacterium, Treponema pallidum, is left untreated for an extended period of time (past the point of blood infection by the organism).[3] The spirochete invades large myelinated fibers, leading to the involvement of the dorsal column medial leminiscus pathway rather than the spinothalamic tract.[citation needed
]

Diagnosis

Routine screening for syphilis. Treponomal antibody usually positive both in blood and in csf also. In CSF lymphocytosis and elevated protein found. Serological tests are usually positive.[citation needed]

Treatment

Intravenously administered penicillin is the treatment of choice. Associated pain can be treated with opiates, valproate, or carbamazepine. Those with tabes dorsalis may also require physical therapy and occupational therapy to deal with muscle wasting and weakness. Preventive treatment for those who come into sexual contact with an individual with syphilis is important.[citation needed
]

Prognosis

Left untreated, tabes dorsalis can lead to

blindness. Existing nerve damage cannot be reversed.[citation needed
]

Epidemiology

The disease is more frequent in males than in females. Onset is commonly during mid-life. The incidence of tabes dorsalis is rising, in part due to co-associated HIV infection.[citation needed]

History

Although there were earlier clinical accounts of this disease, and descriptions and illustrations of the posterior columns of the spinal cord, it was the Berlin neurologist Romberg whose account became the classical textbook description, first published in German[4] and later translated into English.[5]

Sir Arthur Conan Doyle, author of the Sherlock Holmes stories, completed his doctorate on tabes dorsalis in 1885.[6]
