Dejerine–Roussy syndrome

As Thalamussyndrom is known in neurology a complex of symptoms ( syndrome), which is caused by damage to the thalamus in the brain.

History

The Thalamussyndrom described in 1906 by Joseph Jules Dejerine and Roussy Gustave as a stimulus and failure syndrome in clinical and patho-anatomic case reports after massive bleeding or infarction of ventroposterolateralen thalamus.

Symptoms

When Thalamussyndrom Central pain come (also called thalamic pain ) before and neurological deficits.

The following constellation of symptoms is typical of the posterolateral Thalamussyndrom:

• A usually transient mild hemiparesis ( paralysis on one side of the body ),
• Persistent Hemihypästhesie ( general reduction of touch and pressure sensitivity ), often in a hyperesthesia ( hypersensitivity to tactile stimuli ) temporarily, always with impaired proprioception,
• A slight hemiataxia (ataxia Half body esp. of the limbs) as a more or less complete Astereognosie ( tactile agnosia ).

Further, it may be a homonymous hemianopia. Some reflexes are increased. The dystonic movement disorder generally relate to the kontraleralen limb, usually the arm or fingers that are bent at the metacarpophalangeal joints and stretched in the other joints ( Thalamushand ).

The pain often occurs with a long delay (a few months ) and then downright explosive.

Causes

Cause is typically an infarct artery thalamostriate, thalamogeniculata, perforating thalamic anterior or posterior thalamic perforating. According to the different supply areas to the respective different symptoms can be assigned.
