What would happen if the thalamus was damaged?

Karsakoffs syndrome- a disorder caused by the deficiency of thiamine (produced in the thalamus). The thalamus is involved in the relay of signals pertaining to motor activity, language and memory. The brain is a complicated system and any one or more of these functions could be affected negatively due to damage. Basically, it all depends on the source and severity of the damage. A common consequence of thalamus damage is a burning pain affecting mostly the surface of the skin because the thalamus interprets pain signals. There can also be a myriad of other neurological effects including depression, lack of attention and focus, fatigue and many other effects.
