tabes dorsalis

Etymology: L, tabes, wasting, dorsum, the back

an abnormal condition characterized by the slow degeneration of all or part of the body and the progressive loss of deep tendon reflexes, caused by syphilis. This disease involves the posterior columns and posterior roots of the spinal cord and destroys the large joints of affected limbs in some individuals. A wide-base ataxic gait is usually present. It is often accompanied by incontinence and impotence and severe flashing pains in the abdomen and extremities.

tabes [ta´bēz]

1. wasting of the body or a part of it.

2. tabes dorsalis. adj., adj tabet´ic.

tabes dorsa´lis a slowly progressive nervous disorder, from degeneration of the dorsal columns of the spinal cord and sensory nerve trunks, resulting in disturbances of sensation and interference with reflexes and consequently with movements; called also locomotor ataxia. 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 posture sense, and 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.
