Tropical spastic paraparesis from northern India.

In 1964, a progressive myelopathy involving the thoracic region was termed Tropical Spastic Paraparesis (TSP). Subsequently a similar myelopathy associated with HTLV-1 antibodies in both serum and CSF patients were found and named HAM (HTLV-1 associated myelopathy).1 The epidemiological, clinical and pathological features of cases from India are similar to the description form rest of World, though attempts to link TSP and HTLV-1 have largely been unsuccessful. Most of the cases of TSP reported from India are from southern parts of the country. Although sporadic case reports have been made from various other parts, we report an interesting case having features consistent with TSP from northern India.
