Dysarthria clumsy hand syndrome

The "Dysarthria-clumsy-hand" syndrome ( DCHS ) is a clinical picture in neurology that usually occurs in the context of lacunar cerebral infarctions (infarct area smaller than 1.5 cm). The DCHS was first described in 1967 by the Canadian neurologist Charles Miller Fisher .

frequency

In a prospective registry study with 2500 patients, 35 patients with DCHS were identified. This corresponds to a frequency of DCHS of 1.6% based on all strokes, 1.9% based on all ischemic cerebral infarctions and 6.1% based on all lacunar cerebral infarction syndromes.

Clinical picture

The DCHS is characterized by a speech disorder ( dysarthria ) and a clumsy hand (clumsy, clumsy). In addition, one-sided facial paralysis ( facial paralysis ), increased muscle reflexes and a positive Babinski sign typically occur . Some authors also regard the DCHS as a variant of " atactic hemiparesis ".

root cause

Lacunar cerebral infarction is by far the most common cause of DCHS. Less common causes are non-lacunar cerebral infarction, cerebral hemorrhage, and infections. Site of injury is usually the bridge ( Pons , paramedian rostral portion), a portion of the brain stem , or the inner capsule ( capsula interna , usually Crus anterior or Genu), which is located in the cerebrum.
