Answer

Injury to the thalamus following CHI produces posttraumatic thalamic syndrome. In this condition, the person progresses from generalized numbness to episodes of spontaneous pain or pain in response to nonnoxious stimuli. Patients also experience constant or episodic unpleasant sensations (burning, freezing, crushing, formication), paresthesias, outbursts of fear or anger, aphasia, abusive behavior, and signs of frontal lobe dysfunction.
