Tropical spastic paraparesis



Tropical spastic paraparesis (TSP) is a medical condition that causes weakness, muscle spasms, and sensory disturbance by Human T-lymphotropic virus resulting in paraparesis, weakness of the legs. As the name suggests, it is most common in tropical regions, including the Caribbean. Blood transfusion products are screened for HTLV-1 antibodies, as a preventive measure.
