“…Thus, the lack of recruitment found in our MVD patients might also be explained by the fact that these long neuronal pathways were sufficiently preserved to allow patients to process the demanding memory load tasks of our paradigm without excessive physiological effort as opposed to VEAD patients. Hence, it is plausible that in VEAD, the excessive recruitment of compensatory neuronal pools becomes a compulsory neurophysiological mechanism to meet the demanding tasks of our Memory Workload Paradigm (Beuzeron- Mangina and Mangina, 1998, 2000a,b, 2004, 2008, Mangina and Sokolov, 2006. In fact, in our pilot investigations, the phenomenon of a compensatory recruitment was observable only in the very early stages Alzheimer's disease, and it was not visible in the more advanced stages of this illness.…”
