Crossed Cerebellar Diaschisis:A Case Report and Literature Review
The crossed cerebellar diaschisis(CCD)is a condition characterised by reduced blood flow and decreased oxidative metabolism of glucose in the contralateral cerebellar hemisphere following a lesion in one cerebral hemisphere,potentially resulting in crossed cerebellar atrophy in severe cases.It is easy to be overlooked or misdiagnosed in clinical practice.This paper presents a case of ataxia on the left side and worsening cognitive dysfunction resulting from left supratentorial cerebral infarction-induced CCD.The pathogenesis,clinical characteristics,and influencing factors of CCD were elucidated through the literature review to provide references for clinical practice.
