Tabes dorsalis
(Redirected from Tabetic gait)
Tabes Dorsalis[edit | edit source]
Tabes Dorsalis is a serious and specific form of neurosyphilis, an infection of the nervous system by the bacterium Treponema pallidum. This condition is characterized by the slow but progressive degeneration of the sensory neurons in the dorsal columns of the spinal cord, leading to a range of neurological symptoms.
Overview[edit | edit source]
Tabes Dorsalis typically develops in the later stages of untreated syphilis, often years after the initial infection. The degeneration of spinal cord neurons particularly affects the sensory pathways, resulting in a variety of symptoms.
Pathophysiology[edit | edit source]
Tabes dorsalis is a slow degeneration of the nerve cells and nerve fibers that carry sensory information to the brain. The degenerating nerves are in the dorsal columns of the spinal cord (the portion closest to the back of the body) and carry information that help maintain a person's sense of position.
Cause[edit | edit source]
Tabes dorsalis is the result of an untreated syphilis infection.
Signs and symptoms[edit | edit source]
Signs and symptoms include pain, ataxia, loss of coordination, personality changes, blindness, urinary incontinence, dementia, and degeneration of the joints. Symptoms may not appear for some decades after the initial infection.
Sex distribution[edit | edit source]
The disease is more frequent in males than in females.
Onset[edit | edit source]
Onset is commonly during mid-life.
Association with HIV[edit | edit source]
The incidence of tabes dorsalis is rising, in part due to co-associated HIV infection.
Symptoms and Signs[edit | edit source]
Common symptoms of Tabes Dorsalis include:
- Severe pain in the legs and back
- Muscle weakness and loss of coordination (ataxia)
- Sensory impairment leading to loss of reflexes
- Gastrointestinal disturbances
- Bladder dysfunction
Pathophysiology[edit | edit source]
The damage in Tabes Dorsalis results from the destruction of the myelin sheath that surrounds and protects nerve fibers in the spinal cord. This demyelination disrupts normal sensory transmission.
Diagnosis[edit | edit source]
Diagnosis of Tabes Dorsalis involves:
- Clinical evaluation of symptoms
- Serological tests for syphilis
- Neurological examination
- Imaging studies like MRI
Treatment[edit | edit source]
Treatment for Tabes Dorsalis focuses on:
- Antibiotic therapy to treat the underlying syphilis infection
- Symptomatic treatment to manage pain and muscle weakness
- Physical therapy to improve muscle function and coordination
Prevention[edit | edit source]
Prevention of Tabes Dorsalis largely depends on the early detection and treatment of syphilis.
