Tabes

Tabes dorsalis is a late manifestation of untreated syphilis that involves progressive degeneration of the spinal cord. It is characterized by sharp, stabbing pains, lack of coordination, and progressive weakness.

Signs and Symptoms

The symptoms of tabes dorsalis, like those of other forms of neurosyphilis, may not appear for many years after the initial infection. The most common symptoms include:

• Ataxia or unsteady gait
• Paresthesia or abnormal sensations in the skin
• Severe, stabbing pains
• Loss of muscle coordination
• Progressive muscle weakness

Causes

Tabes dorsalis is caused by the bacterium Treponema pallidum, which also causes syphilis. The bacterium damages the spinal cord and peripheral nerves, leading to the symptoms of the disease.

Diagnosis

Diagnosis of tabes dorsalis involves a physical examination and a review of the patient's medical history. Tests that may be done include:

• Blood tests to check for syphilis
• Lumbar puncture to check for signs of infection in the spinal fluid
• MRI or CT scan to check for damage to the spinal cord

Treatment

Treatment for tabes dorsalis involves antibiotics to kill the syphilis bacteria. Pain management and physical therapy may also be needed to manage symptoms.

Prognosis

With early diagnosis and treatment, the prognosis for tabes dorsalis is good. However, if left untreated, the disease can lead to severe disability and even death.
