HAM/TSP
HLTV-1 Associated Myelopathy / Tropical Spastic Paraparesis
What is HAM/TSP?
HTLV-1 Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) is a chronic inflammatory disease of the spinal cord caused by HTLV-1.
It affects the nervous system and can lead to progressive disability over time.
What causes HAM/TSP?
HAM/TSP occurs when the immune system reacts against HTLV-1 infected cells, causing inflammation and damage within the spinal cord.
Only a small percentage of people with HTLV-1 develop HAM/TSP.
Common symptoms
Symptoms often develop gradually and may worsen over years.
Symptoms may include:
Leg
weakness
Muscle stiffness/spasticity
Difficulty
walking
Balance
problems
Chronic
pain
Numbness
or tingling
Urinary urgency
or incontinence
Constipation
Sexual

Fatigue
How is HAM/TSP diagnosed?
Diagnosis usually involves:
01
HTLV-1 blood testing
02
Neurologic examination
03
MRI imaging
04
Exclusion of other neurologic disorders
05
Lumbar puncture/spinal fluid analysis
Evaluation by neurologists experienced in neuroimmunologic diseases is often helpful.
Treatment Options
There is currently no definitive cure for HAM/TSP, but treatment may help reduce inflammation and slow progression.
- Physical therapy
- Interferon-alpha
- Immunosuppressive medications
- Physical therapy
- Pain management
- Interferon-alpha
- Spasticity treatments
- Bladder management strategies
Some patients may qualify for clinical trials investigating novel therapies.
Rehabilitation and quality of life
Comprehensive care may include:
- Physical therapy
- Occupational therapy
- Mobility support
- Psychological support
- Social services
- Rehabilitation medicine specialists
Early supportive care can significantly improve quality of life and independence.
