HTLV 1–Associated Myelopathy Tropical Spastic Paraparesis (HAM TSP)
Symptoms of HAM TSP
In people with HTLV-1–associated myelopathy/tropical spastic paraparesis, the muscles in both legs gradually become weak. People may not be able to feel vibrations in their feet and may lose the sense of where their feet and toes are (position sense). Their limbs feel stiff, movements become clumsy, and walking may become difficult. Muscle spasms in the legs are common, as is loss of bladder control ( Urinary Incontinence in Adults ) and urinary urgency (an urgent need to urinate). HAM/TSP usually progresses over several years.
