Abstract
Schmahmann (1998) described the ‘cerebellar cognitive affective syndrome’, (CCAS) reporting impairments in executive functions, disturbances in spatial cognition, language deficits and personality changes in subjects with cerebellar pathologies. The current CCAS literature consists of only small series of patients that are frequently biased by patient selection rather than consecutive inclusion, and is clear that stroke in the anterior lobe for occlusion of Anterior Inferior Cerebellar Artery (AICA) produced the motor syndrome but not the CCAS, whereas stroke in the posterior lobe posterior Inferior Cerebellar Artery (PICA) produced the CCAS.
