Five tasks were used to assess components \nof action knowledge (action\u2013tool relationships, pantomime \nrecognition, and sequential organization of action) and \npraxis execution (actual use, pantomiming) according to \nthe cognitive model of praxis. Three tasks (verbal comprehension, \nnaming, and a visual semantic matching task) were used \nto assess verbal\u2013visual semantics. Considering patterns \nof apraxia first, conceptual apraxia was found in 9 out \nof the 10 AD patients, suggesting that it is a common feature \neven in the early stages of AD. Second, we found partly \nparallel deficits in tests of action-semantic and verbal\u2013visual \nsemantic knowledge in 9 AD patients. Impaired action knowledge \nwas found only in patients with a semantic language deficit. \nThese findings provide no evidence that \u201caction semantics\u201d \nmay be separated from other semantic information. Our results \nsupport the view of a unitary semantic system, given that \nthe representations of action-semantic and other semantic \nknowledge of objects are often simultaneously disrupted \nin AD.
