thalamic syndrome

tha·lam·ic syn·drome

a syndrome produced by infarction of the posteroinferior thalamus causing transient hemiparesis, severe loss of superficial and deep sensation with preservation of crude pain in the hypalgic limbs that frequently have vasomotor or trophic disturbances.

thalamic syndrome

Etymology: Gk, thalamos + syn, together, dromos, course
a vascular disorder involving the ventral and posterolateral nuclei of the thalamus and related nerve fibers. It causes disturbances of sensation and partial or complete paralysis of one side of the body. A major effect is an increased threshold to all stimuli on the opposite side of the body so that any stimuli may cause an exaggerated response. Also called Dejerine-Roussy syndrome.

thalamic syndrome

Dejerine-Roussy syndrome, thalamic hyperesthetic anesthesia A condition caused by infarction of the posteroinferior thalamus Clinical Transient hemiparesis, loss of deep and superficial nociception, with preservation of positional sense; with time, trophic changes occur

Dejerine anterior bulbar syndrome - occlusion of anterior spinal arteries with involvement of cortical spinal tract, hypoglossal nerves, and medial lemnisci.
Dejerine cortical sensory syndrome - (1) radiculitis; - (2) bulbar syndrome caused by medullar lesion and resulting in cranial nerve paralysis in the area; - (3) polyneuropathy resulting in depression of deep sensation; tactile sensation remains normal.

Dejerine-Roussy syndrome - infraction of posteroinferior thalamus causing transient hemiparesis, severe loss of superficial and deep sensation with preservation of crude pain in the limbs with decreased sensation; the limbs frequently have vasomotor or trophic disturbances.
