“…reading for a highschool level adult) or a representation strongly activated (for example, following repeated exposures) will require more cognitive resources to be suppressed than few skilled processes or less activated representations. Due to their memory problem, AD patients process information less deeply than normal elderly [103], or they forget more quickly the information previously encoded (see for a review [85]). Consequently, the memory traces on which suppression will apply will be less strong in AD patients and suppression of that information will require less effort than for normal elderly subjects.…”

Deficits of suppression abilities are frequently observed in normal aging and Alzheimer's disease.However, few studies have explored these deficits in the two populations simultaneously using a large battery of tasks. The aim of the present study was to explore if the pattern of performance presented by elderly subjects and AD patients is in agreement with theoretical frameworks [104; see also 81], distinguishing between the concepts of inhibition (a voluntary suppression of irrelevant information) and interference (an automatic suppression process occurring prior to conscious awareness). The results obtained demonstrated that (1) there is an alteration of the inhibitory process in normal elderly subjects; (2) inhibitory and interference resolution processes are quantitately less efficient in AD, since these patients present a correct performance only for information which leaves weak traces in memory.

“…It was the introduction of the semantic priming paradigm that could detect evidence of semantic relationships while minimizing the attentional and retrieval demands of tasks such as card sorting, that raised the real possibility that deficits other than semantic structure might account for the poor performance by aphasic individuals on semantic tasks (e.g., Milberg & Blumstein, 1981). Nebes, Martin, and Horn (1984) used these observations to test the then-emerging claim that patients with dementia suffered from a differential deficit in semantic knowledge (e.g., Weingartner, Kaye, Smallberg, & Ebert, 1981). The introduction of the semantic priming paradigm into the debate began what was to become a strange parallel universe of studies representing the degradation view (e.g., Chan, Salmon, Butters, & Johnson, 1995;Grober, Buschke, Kawas, & Fuld, 1985) and the impaired-access view of the semantic deficit of AD (e.g., Balota & Duchek, 1991;Nebes & Brady, 1991;Ober & Shenaut, 1988).…”

Verstraeten, and P. P. De Deyn (2003) bring into focus at least 3 important issues. First, the performance of even simple tasks may be affected by several basic cognitive processes. Second, the statistical variance that these processes contribute to task performance may be different for a group of participants with neuropsychological deficits than for normal control particpants. Third, claims regarding the nature of semantic memory in Alzheimer's disease (AD) reflect indeterminacy about the nature and assessment of semantic memory itself. Critically, their analysis suggests that the T. Shallice and E. K. Warrington (1979) criteria widely used to operationalize the semantic memory deficit in AD be carefully scrutinized and reevaluated.

“…or begin with a specified letter. As with confronta tion naming, word fluency is reduced in DAT [1,[6][7][8][9][10][11][12], it correlates highly with dementia severity [1] and allows discrimination of many DAT patients from controls, although mild cases cannot always be differentiated from controls [1]. Appell et al [6] report fluency to have been the least impaired of all language functions they tested.…”

In a longitudinal study of 90 patients with mild to moderate dementia of the Alzheimer type (DAT) we investigated the relative severity of impairment in a confrontation naming, a categorical word fluency and a word list recall task. Severity of impairment was assessed in comparison to a healthy age-matched control group. At baseline, confrontation naming and fluency deficits were about equally often the most severe deficit. The number of patients with most severe naming deficits increased from mild to moderate dementia and from baseline to 1-year follow-up. Word recall was the most severe deficit only in a minority of patients. An addition of lexical-semantic and visual-perceptive dysfunctions is discussed as a possible cause for the shift towards naming deficits in the course of the disease.
