RESUMO

O autor disserta sobre a definição de Paraparesia Espástica Tropical desde suas primeiras descrições até o envolvimento etiológico do HTLV-1 em parte dos casos. Segundo o autor, o núcleo básico da síndrome inclui uma paraparesia com sinais piramidais (espasticidade e hiperreflexia) e sinais sensitivos e esfincteríanos variáveis. A etiologia retroviral pelo HTLV-1 constitui um dos elementos variáveis da condição. Ele objetiva prevenir distorções conceituais na descrição dessa condição.

Palavras-chave: paraparesia espástica tropical, definição clínica, etiologia.
