Schmahmann's syndrome represents a novel clinical condition consisting of a constellation of cognitive and affective deficits following cerebellar disease. The complex was first described in 1998 as cerebellar cognitive affective syndrome (CCAS) on the basis of a careful neurological examination, detailed bedside mental state tests, neuropsychological investigations and anatomical neuroimaging of a group of 20 patients with focal cerebellar disorders. The syndrome was characterized by four clusters of symptoms including: (a) impairment of executive functions such as planning, set-shifting, verbal fluency, abstract reasoning and working memory, (b) impaired visuo-spatial cognition, (c) personality changes with blunting of affect or abnormal behaviour, and (d) language deficits including agrammatism, wordfinding disturbances, disruption of language dynamics and dysprosodia. This complex of neurocognitive and behavioural-affective symptoms was ascribed to a functional disruption of the reciprocal pathways that connect the cerebellum with the limbic circuitry and the prefrontal, temporal and parietal association cortices. With the introduction of Schmahmann's syndrome, clinical ataxiology has found its third cornerstone, the two others being the cerebellar motor syndrome (CMS) mainly delineated by the pioneer French and English neurologists of the 19(th) and early 20(th) century, and the vestibulo-cerebellar syndrome (VCS) consisting of ocular instability, deficits of oculomotor movements and ocular misalignment.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 16. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 August 2022.
All research outputs
of 25,320,147 outputs
Outputs from Cerebellum & Ataxias
of 103 outputs
Outputs of similar age
of 262,244 outputs
Outputs of similar age from Cerebellum & Ataxias
of 3 outputs
Altmetric has tracked 25,320,147 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 103 research outputs from this source. They receive a mean Attention Score of 3.3. This one has done particularly well, scoring higher than 96% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 262,244 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 3 others from the same source and published within six weeks on either side of this one.
