For example, Schmahmann described "cerebellar cognitive affective syndrome," which includes impairments in executive functions, visuospatial, and linguistic abilities, along with a large spectrum of affective symptoms ranging from depression and affective blunting to disinhibition and psychotic symptoms, in patients having cerebellar lesions
Sixteen (20%) patients in the MS group had midbrain lesions, 39 (49%) had pontine lesions, 18 (23%) had medullary lesions, 52 (66%) had periventricular lesions, 29 (37%) had juxtacortical lesions, and 14 (18%) had cerebellar lesions
A study of primary portine, cerebellar lesions
with observations on pathogenesis.
A study in humans showed that cerebellar lesions
are associated with a decrease in the activity of the amygdala as well as of the cingulated gyrus (18).
In this case, the clinical signs observed were characteristic of cerebellar lesions
(WASHBURN & STREETER, 2004).
Multiple lesions were seen in 10 patients; in 2, a single lesion was seen in the centrum semi-ovale, and bilateral cerebellar lesions
were seen in 1.
In our patients lateral focal cerebellar lesions
induce ipsilateral signs, although expanding lesions may produce a false localization of clinical signs Amarenco (1995).
involving the floccular region also reduce or eliminate OKNe towards the side of the lesion.
result in cerebellar signs, while supratentorial lesions lead to hemiparesis, mental status changes and speech difficulties.

Brain magnetic resonance imaging (MRI) showed T1-low and T2-high bulbopontine and cerebellar lesions
around the fourth ventricle (Figure).
