The aim of the study was to describe a case of the patient with cerebellar cognitive affective syndrome
CCAS, characterize the role of cerebellum in the regulation of cognitive functions and present the
procedure of neuropsychological diagnosis useful in indicating the specific cognitive and emotional problems
in patients with cerebellar damage.
Case report. A 41- year old man with an ischemic cerebellar stroke of its right hemisphere manifested
the neuropsychological symptoms typical for the frontal damage: euphoric mood, disorganized behavior,
lack of criticism and mental plasticity, tendency to shorten the personal distance, problems with mistake
correction. In neuropsychological diagnosis we used following methods: Raven Progressive Matrices
Test, Mini Mental Stage Examination (MMSE), Trail Making Test, Wisconsin Card Sorting Test, Stroop
Interference Test, Word Fluency Test, Auditory Verbal Learning Test by Łuria, Benton Visual Retention
Test, Digit Span.
Results. Analyzing the obtained results we observed the significant decrease of all executive functions:
planning, abstract thinking, cognitive flexibility, adaptation to new situations as well as memory impairments
and changes in emotional and behavioral state similar to frontal syndrome. The whole of impairments
including the typical cerebellar symptoms (ataxia, dysarthria, dysmetria,hypotonia) create the cerebellar
cognitive affective syndrome CCAS with leading role of dysexecutive syndrome.
Conclusions. The cerebellum takes part in the regulation of cognitive functions. The cerebellar damages
can imitate the emotional- cognitive problems of patients after frontal damages what additionally stress
the functional link between these two brain structures. Patient’s with cerebellar damages should have neuropsychological
and neuropsychiatric diagnosis and care.
