Anterior Spinothalamic Tract Strokes

The anterior spinothalamic tract is a pathway in the spinal cord? that carries sensory information related to light touch and pressure from the skin to the brain. Strokes affecting this tract can disrupt these sensory signals, leading to various symptoms.

Types of Strokes:

Strokes affecting the anterior spinothalamic tract can be ischemic or hemorrhagic. Ischemic strokes occur when a blood vessel supplying the spinal cord is blocked, while hemorrhagic strokes result from the rupture of a blood vessel.
