Tropical Spastic Paraparesis (TSP) is a neurological condition characterized by weakness and stiffness in the legs. It is often caused by infection with the Human T-Lymphotropic Virus type I (HTLV-I), which is prevalent in certain tropical regions. Symptoms typically include difficulty walking, muscle spasms, and sensory changes in the lower limbs. The condition can progress slowly over time, leading to increased disability. Diagnosis is usually made through clinical evaluation and blood tests for HTLV-I. While there is no cure for TSP, treatments focus on managing symptoms and improving quality of life through physical therapy and medications.
