Subjective Report of Word-finding and Memory Deficits in Normal Aging and Dementia

Abstract

Objective Compare subjective reports of both memory and word-finding deficits to clinical diagnosis and objective neuropsychological testing. Background With the increasing number of aging individuals with cognitive impairments, effective screening measures would improve the likelihood of detection. Subjective reports of symptoms are typically obtained in clinical settings, yet the validity of these reports is relatively unknown. Methods Clinical screening for dementia was carried out at an Alzheimer’s disease center. Dichotomous ratings for memory and word-finding/language problems were given by subjects and neurologists. These ratings were compared with 13 neuropsychological measures of word finding/language and episodic memory. Results Ratings of memory by both subjects and neurologists correlated well with standard neuropsychological measures of memory. However, both the patients’ and physicians’ ratings of word finding/language impairments had notably less of a correlation with the relevant neuropsychological measures of word finding/language. Conclusion Compared to ratings of memory, similar assessments of word-finding/language difficulties were relatively inaccurate and thus poor predictors of impairment. It is imperative to develop effective screening methods that will help reveal cognitive impairments, as this issue will almost certainly become more pressing given the projected increase in the number of aging individuals and those with dementia.

Examining the relationship between subjective and objective memory performance in older adults: A meta-analysis.

“…This analysis was conducted with the assumption that some studies that did not screen for MCI may have included some MCI participants in their normatively aging sample. Some research has identified that individuals with MCI are more accurate when making memory judgments (Calley et al, 2010; Cook & Marsiske, 2006). This may be because individuals with MCI recognize that their memory performance has changed over time and they then match their perceptions about their memory to reflect this notion of decline.…”

The neuroanatomic correlates of semantic memory deficits in patients with Gulf War illnesses: a pilot study

“…Two of the most salient symptoms are word-finding and memory difficulties (see Calley et al 2010). Several studies of the symptoms reported by veterans with Gulf War Illnesses corroborate reports of difficulties with word finding (Fukuda et al 1998; Barrett et al 2002) and/or memory (Pierce 1997;Fukuda et al 1998;Gray et al 2002;Ishøy et al 1999); however, the incidence and prevalence of deficits related to semantic memory with these symptoms, the etiology of the impairments, and the brain regions involved are unknown.…”

The Increase of D-Amino Acids in Alzheimer′s Disease-Related Proteins Isolated from the Brains of SAMP8 Mice

“…Mouse studies suggest that PP1 functions as a suppressor of learning and memory (Genoux et al 2002). Because defects in learning and memory are among the signs of Alzheimer's disease (Calley et al 2010), a relationship between PP1 and…”
