Wallenberg syndrome may cause Horner syndrome and cerebellar ataxia. Horner syndrome can cause a lack of sensation on one side of the face and weakness of the palate, pharynx, and vocal cords which may result in difficulty swallowing and hoarseness. Cerebellar ataxia refers to uncoordinated muscle movement, which can cause walking problems (unsteady gait), sudden eye movements (nystagmus), and clumsy speech patterns (dysarthria). Other symptoms of Wallenberg syndrome may include dizziness, nausea, vomiting, loss of taste on one side of the tongue, uncontrollable hiccups, and vision disturbance. Wallenberg syndrome may also cause a loss of pain and temperature sensation in the side of the body that is opposite to where the stroke occurred.
