This experiment explored knowledge of four types of semantic relations (superordinate category, part, property, and function) in Alzheimer's disease (AD) subjects and age- and education-matched controls. Moderate AD subjects showed the greatest disruption on functional relations, intermediate disruption on part and property relations, and the least...

Semantic memory includes knowledge about the use of language, memory for words, their meanings, as well as the relations among concepts (e.g., knowing that a saw is a tool, has a blade, is sharp, and can be used for cutting). The present studies explored the impact of dementia of the Alzheimer-type (DAT) on one aspect of semantic memory, functional...

To examine the perceptual processes that support reading and memory, we examined the effect of the polarity of both reading text and word-stem completion task (black text on white paper vs. white text on black background). Subjects read a passage of 380 words, in both polarities. They then were asked to associate cities with states for two minutes....

Participants made judgments about the relative salience of category exemplars (e.g., fruit: apple or grape) or parts (e.g., plane: wings or seats). Mildly affected Alzheimer's disease (AD) patients were as accurate but slower than normal controls, and their response times increased more for related (e.g., apple, grape, or fig) than unrelated (e.g.,...

Alzheimer's disease (AD) patients and elderly controls verified semantic attributes of common concepts. For each attribute tested (superordinate category, part, property, and function), typicality of the semantic relation was varied, as well as the order in which relations were tested (e.g., category-concept or concept-category). Like controls, AD...

Objective. —To compare efficacy and safety of tacrine hydrochloride with placebo in patients with probable Alzheimer's disease. Design. —A 12-week, double-blind, placebo-controlled, parallel-group study. Setting. —Outpatients at 23 centers. Patients. —Men and women with probable Alzheimer's disease, at least 50 years old, mildly to moderately im...

We describe an in vivo method for the quantitative analysis of human necrotical anatomy. The technique allows unfolded regions of functional and morphological interest to be measured planimetrically. Two-dimensional cortical maps and surface area determinations derived from magnetic resonance images of monozygotic twins are presented. In addition,...
