Hemispheric syndrome

The hemisphere syndrome (or Hemisyndrom ) is created by an extensive damage to a cerebral hemisphere and possibly also the deeper basal ganglia and the diencephalon associated thalamus . It connects neurological deficits that usually affect one (namely the opposite) side of the body. Typical symptoms are the hemiplegia ( hemiparesis or hemiplegia ), semi-side sensory disturbances , Hemi chorea or - ballism , unilateral spasticity and / or hemianopia and forced views phrase ( "stove view" déviation conjuguée ) or view paresis . In the neuropsychological failure phenomena, which often occur in combination , the hemisymptomatic relates to the opposite space segment. Come here - especially in the lesion did not speak dominant hemisphere - agnosias up to the (hemi) neglect ; if the language-dominant hemisphere is damaged, aphasia and apraxia occur.

An acute hemispheric syndrome usually occurs with extensive cerebral haemorrhage or cerebral infarction due to the closure of central blood vessels supplying the brain , which is usually the internal carotid artery or the media cerebral artery or one of its branches.

In contrast, brainstem lesions have "crossed" symptoms with different deficits on both sides of the body and additional cranial nerve failures ( brainstem syndromes , for example Wallenberg syndrome , Benedict syndrome , Weber syndrome ).
