tabes dorsalis[′tā·bēz dȯr′sal·əs] (medicine) A form of parenchymatous neurosyphilis in which there is demyelination and sclerosis of the posterior columns of the spinal cord. Also known as locomotor ataxia. Tabes Dorsalis a late form of the syphilitic infection of the nervous system that primarily affects the meninges, the dorsal roots of the spinal nerves, and the posterior columns of the spinal cord. The first symptoms of tabes dorsalis appear from three to 30 years (usually approximately ten years) after infection. The disease is manifested by whooping cough, labored breathing, pupillary changes, and pain and paresthesia (formication, numbness, tingling in the legs, paroxysms of intense pain in the internal organs [tabetic crises]). Disturbances of musculoskeletal sensation in the legs is impaired, resulting in a sharp decrease in muscle tone, the loss of reflexes, and incoordination (specifically, ataxic gait). Also characteristic is tissue malnutrition, which is marked by joint deformities, an increased bone fragility, ulceration of the soles of the feet, loss of hair, and severe emaciation. Infection of the optic nerve with tabes dorsalis may cause vision disturbances and sometimes blindness. V. A. KARLOV tabes dorsalis

It is caused by syphilis and may appear 5 to 20 years after initial infection. Its course is slow but progressive; it can often be arrested, but complete cure is rare. The first symptoms are pain in the lower limbs, upper limbs, or trunk, loss of sense" >posture sense, and pupils" >Argyll Robertson pupils (pupils that are uneven and do not react to light). Unless the patient looks down at his legs he does not know where they are and must depend on his vision for each step. The typical gait of a tabetic patient is jerky and wide-based.tabes mesente´rica tuberculosis of the mesenteric glands in children.tabes dorsalis (dôr-sā′lĭs, -săl′ĭs)n.

Also called locomotor ataxia.tabes dorsalis A complication of untreated syphilis consisting of slowly progressive degeneration of the dorsal/posterior columns of the spinal cord, which are seen a decade or more after infection, in late or tertiary phase of syphilis. Clinical findings Sharp pain, ataxia, optic-nerve degeneration leading to blindness, urinary incontinence, loss of position sense, joint degeneration (aslo known as Charcot’s joints).tabes dorsalis Tabes syphilis, tabetic neurosyphilis Neurology Slowly progressive degeneration of the dorsal/posterior columns of the spinal cord typical of late or tertiary phase of syphilis, which occurs a decade or more after infection, when it is improperly treated Clinical Sharp–lightning pain, ataxia, optic nerve degeneration leading to blindness, urinary incontinence, loss of position sense, joint degeneration, aka Charcot's joints. See Charcot's joints, Syphilis. Cf Friedreich's tabes, Pseudotabes. ta·bet·ic neu·ro·syph·i·lis (tă-bet'ik nūr'ō-sif'i-lis) Type of neurosyphilis in which the posterior roots of the spinal cord, especially in the lumbosacral area, are the principal sites of infection, resulting in ataxia, hypotonia, impotence, constipation, hypotonic bladder, areflexia, and Romberg sign; other findings include lancinating pains (most often in the legs), visceral crises, Argyll-Robertson pupils, optic atrophy, and neuropathic joints. In most patients, the cerebrospinal fluid contains antibodies to Treponema pallidum. Synonym(s): tabes dorsalis. tabes dorsalis Degeneration of the sensory nerve columns in the rear part of the spinal cord caused by untreated SYPHILIS. There are severe, stabbing ‘lightning’ pains in the legs or lower trunk, unsteadiness and a characteristic gait in which the feet are kept well apart, lifted high and stamped forcibly. Joint damage and foot ulcers occur and vision may be affected by optic nerve involvement. Treatment with penicillin can arrest the progress of the disease. Also known as locomotor ataxia.Tabes dorsalisA progressive deterioration of the spinal cord and spinal nerves associated with tertiary syphilis.Mentioned in: Syphilistabes dorsalis A degenerative disease of the posterior columns of the spinal cord, the posterior spinal roots and the peripheral nerves accompanied by a number of ocular signs and symptoms such as atrophy of the optic nerve, visual field defects, ptosis, Argyll Robertson pupil and paralysis of one or more of the extraocular muscles. The disease is a result of neurosyphilis.ta·bet·ic neu·ro·syph·i·lis (tă-bet'ik nūr'ō-sif'i-lis) Type of late tertiary syphilis, seen predominantly in men; its major clinical manifestations are ataxia, urinary incontinence, and brief lancinating pains ("lightning pains"), which can affect any portion of the body, but particularly the legs. Synonym(s): tabes dorsalis. FinancialSeeTDtabes dorsalis
