abstract = {The cerebellum has been shown to contribute to different
cognitive functions such as verbal fluency and different
aspects of executive functioning, which are also commonly
impaired in amyotrophic lateral sclerosis (ALS) patients.
Whereas cerebellar involvement has been indicated in ALS
patients in general, its relative contribution to the
patients' specific cognitive deficits remains unclear. In
the current analyses, the demographic, clinical,
neuropsychological and imaging data of 120 ALS patients and
88 healthy controls were analysed. Grey matter volume (GMV)
and white matter (WM) fractional anisotropy were extracted
for a comprehensive list of cerebral and cerebellar regions
and bootstrapped elastic net regularized regression analyses
were employed to identify regional structural metrics that
were related to various cognitive scores. We further
examined the stability of predictor variables selection and
the regression coefficient distributions across the
bootstrap samples. Both regional GMV and WM integrity are
featured as informative predictors for patients' cognitive
scores. The GMV of cerebellar lobules V and VIIIa were
related to semantic fluency, but cerebellar regions did not
reliably contribute to other cognitive outcomes. The GMV of
pallidum was positively correlated with fluency outcomes and
working memory, whereas hippocampus volume was positively
related to fluency and episodic memory outcomes.
Unsurprisingly, educational achievement emerged as the most
general and reliable predictor of cognitive performance.
Based on the current findings, cerebellar GMV seems to be
specifically associated with semantic fluency performance in
ALS patients but not any of the other cognitive measures.
Further cognitive functions were associated with both
cerebral grey matter (GM) and WM metrics. Future
investigations could examine the possible involvement of the
cerebellum in the affective and social-emotional dysfunction
present in a subset of ALS patients.},
