%X apraxia is classically defined as a difficulty or inability to imitate gestures, produce pantomimes of tool's use, or make gestures to verbal command. in apraxia assessment, gestures can be classified in transitives, intransitives, and non-familiars. the movements are classified according to the purpose of the motor act: if involves manipulation of an object, if serves to communicate ideas or feelings, or if it lack of any practical or symbolical value. whilst the selective impairment for the processing of transitive gestures was widely reported, a deficit restricted to intransitive gestures was reported only exceptionally. although it has been reported dissociation between different types of gestures, is usual in apraxia assessment that these three categories of gestures don't be considered separately or that varies the definition of these categories. the aim of this study was verify the presence of dissociations between transitives, intransitives, and non-familiars gestures in a same group of patients with alzheimer-type dementia, that was previously described in the praxias performance of patients with focal lesions (gonz¨˘lez rothi, mack, verfaellie, brown, & heilman, 1988; negri et al., 2007). it was assessed imitation of transitives, intransitives and non-familiar gestures, and the use of objects, in 50 patients of the neurology department of eva per¨®n hospital (buenos aires -argentina) diagnosed with probable alzheimer-type dementia, under the diagnostic criteria of nincds - adrda. the alzheimer-type dementia group performed the tasks significantly worse than healthy controls. 72% showed deficit in the per formance of at least one of the praxis battery tests. in alzheimer-type dementia group, each praxis subtest are significantly and positively correlated with the others. however, there were dissociations in the performances at the single-case level analysis. one patient (case 3) showed a selective deficit in imitation of intransitives gestures, while retainin
