Question

Which part is mostly degenerated in spinal cord in patients with HAM/TSP? a. Anterior column b. Lateral column c. Posterior column

Short answer

a. Anterior column b. Lateral column c. Posterior column Answer: b. Lateral column Explanation: HAM/TSP is a neurological disorder caused by the human T-cell lymphotropic virus type 1 (HTLV-1), which primarily affects the lateral column of the spinal cord. This degeneration results in motor and sensory problems, such as muscle weakness, spasticity, and difficulty with balance and coordination. The anterior and posterior columns are less impacted in this condition.

Step-by-step solution

Correct Answer

The correct answer is option b. Lateral column.

Explanation

The lateral column of the spinal cord is mainly affected in patients with HAM/TSP. The degeneration of the lateral column leads to motor and sensory problems, such as muscle weakness, spasticity, and difficulty with balance and coordination. The anterior and posterior columns are less affected in this condition.
