INTRODUCTION: @entity191 is a neurodegenerative condition involving @entity73 . It is important to know why all these different deficits co-occur in the affected @entity1 . This paper aims to clarify whether these comorbid deficits result from the selective impairment of a computational primitive, namely, a context-sensitive computational ability according to Chomsky's Hierarchy (a well-established research tool in comparative neuroscience). @entity1 AND METHODS: A total of 15 medicated subjects with @entity191 and 15 controls were selected. They were matched in age and education. A battery of tasks was designed to test 3 different domains (motor capacities, cognition, and language) and 2 different computational abilities (context-free and context-sensitive operations). RESULTS: Significant differences between groups were observed only regarding the linguistic task involving context-sensitive computations (correferences). CONCLUSIONS: The observed deficits in our @entity1 with @entity191 cannot be explained in terms of the selective impairment of one only unspecific, low-level computational process. At the same time, differences between @entity1 and controls are expected to be greater if the former are not medicated. Moreover, we should pursue in the search of (this kind of) computational primitives than can be selectively impaired in @entity1 with @entity191 , because they may help to achieve an earlier diagnosis of this condition.
