Destructive lesions of the complex thalamic nuclei are relatively unusual causes of sensory symptoms. When the ventral posterior lateral (VPL) and ventral posterior medial (VPM) thalamic nuclei (Chapters 2 and 5) are damaged, such as following a thrombo‐embolic stroke, contralateral hemi‐anaesthesia follows immediately. Sometimes, however, during the weeks or months following the stroke, highly unpleasant disabling persistent pain (post‐stroke central pain, a.k.a. thalamic pain, Chapter 23) develops in partially anaesthetic limbs. Pain is usually permanent.
