Purpose: The primary aim of this contribution is to provide a critical discussion on cognitive and sociocognitive implications of spinocerebellar ataxias (SCAs) subtypes. The term SCA refers to a group of neurodegenerative disorders that have been increasingly investigated in the last years, sharing the characteristic of progressive ataxia resulting from degeneration of cerebellum and its connections. In past decades only involvement of cerebellum in behaviour and timing has been investigated, bringing to the belief about its central role in timing of movement and sensation, particularly for short intervals of time. Only very recently the cerebellum has been considered as a potentially important centre for cognitive processing and related spheres of social cognition, so that several studies with SCA patients have been carried out on these topics: as a consequence a section of this review will be dedicated to this important aspect. Results: After a brief discussion on most commonly used methods to assess cognitive and sociocognitive abilities in SCAs, cognitive and socio-cognitive profiles of principal SCA subtypes have been thoroughly reviewed and critically discussed. Due to the very poor literature in this field the most common SCA variants have been fully included (i.e. SCA1, SCA2, SCA3, SCA6 and SCA7). Conclusions: A comparative summary of the main characteristics of cognitive and social cognition deficit in SCA subtypes has been proposed together with a research agenda for future investigation in this field principally aimed at using measures of cognition and/or social cognition as potential predictors of the extent and progression of disease.
