Disorders

The full extent of the damage caused by occlusion of the anterior choroidal artery is not known. However, studies[which?] show that the interruption of blood flow from this vessel can result in hemiplegia on the contralateral (opposite) side of the body, contralateral hemihypoesthesia, and homonymous hemianopsia.

These symptoms are thought to arise from ischemic damage to the posterior limb of the internal capsule.
