Evaluation of the performance of normal elderly in a limb praxis protocol: influence of age, gender, and education.

29 Jun 2009 Limb praxis can be influenced by age, gender, and education. The present study investigated the influence of these variables on gesture production by healthy elderly subjects. We evaluated 96 individuals divided into two age groups (60-74 and 75-88 ... Read more...

Semantic memory in object use.

27 May 2009 We studied five patients with semantic memory disorders, four with semantic dementia and one with herpes simplex virus encephalitis, to investigate the involvement of semantic conceptual knowledge in object use. Comparisons between patients who had ... Read more...

Cognitive mechanisms of visuomotor transformation in movement imitation: examining predictions based on models of apraxia and motor control.

24 May 2009 When we observe a movement and then reproduce it, how is this visual input transformed into motor output? Studies on stroke patients with apraxia suggest that there may be two distinct routes used for gesture imitation; an indirect route that ... Read more...

Technical information about 'Apraxias'

Definition: A group of cognitive disorders characterized by the inability to perform previously learned skills that cannot be attributed to deficits of motor or sensory function. The two major subtypes of this condition are ideomotor (see APRAXIA, IDEOMOTOR) and ideational apraxia, which refers to loss of the ability to mentally formulate the processes involved with performing an action. For example, dressing apraxia may result from an inability to mentally formulate the act of placing clothes on the body. Apraxias are generally associated with lesions of the dominant PARIETAL LOBE and supramarginal gyrus. (From Adams et al., Principles of Neurology, 6th ed, pp56-7)
