A rare neurological condition where damage to the part of the brain that controls sensation (thalamus) is damaged causing excessive pain in response to mild stimulation or reduced sensation. See also Déjerine-Roussy syndrome

Thalamic hyperesthetic anesthesia is a medical condition characterized by a combination of heightened sensation and reduced pain perception in the affected area. It is caused by damage to the thalamus, a part of the brain that is involved in sensory processing.

Individuals with thalamic hyperesthetic anesthesia often experience severe, constant pain in the affected area, which can be exacerbated by even mild stimuli such as touch, pressure, or temperature changes. At the same time, they may have reduced sensitivity to painful stimuli in the affected area, and may even feel a sense of numbness or tingling.

Thalamic hyperesthetic anesthesia can occur as a result of a variety of underlying medical conditions, including stroke, brain injury, or tumors affecting the thalamus. Treatment typically involves addressing the underlying cause of the condition, as well as the use of pain management techniques to help alleviate the individual’s symptoms.

Overall, thalamic hyperesthetic anesthesia is a rare but debilitating medical condition that can significantly impact an individual’s quality of life. It requires careful medical management and ongoing treatment to manage symptoms and address the underlying cause of the condition.
