Caregiver report of prevalence and appearance order of linguistic symptoms in Alzheimer's patients

What spouse caregivers know about communication in Alzheimer's disease: development of the AD Communication Knowledge Test

Most individuals with Alzheimer's disease are cared for at home by family members, particularly spouses. As language impairment progresses, communication between spouses becomes difficult and caregivers are likely to be unprepared for this challenge. The purpose of this study is to describe spouse caregivers' knowledge of communication in AD and to determine their learning needs regarding effective communication strategies. A measure of knowledge about declining language skills and appropriate communication strategies was developed and pilot tested. Participants included 16 spouses caring for a partner with AD at home. Care recipients were generally mildly impaired. Caregivers were aware of at least some of the decline in language but were less knowledgeable about communication strategies. They were experiencing numerous communication problems, but reported minimal difficulty in communicating. Nurses in acute and long-term care settings are challenged to assess spouses' knowledge and awareness about communication in AD and provide information about effective communication strategies to decrease misunderstandings and frustration, which often lead to behavior problems. Recommendations for further development of the AD Communication Knowledge Test are offered.

Dysgraphia in Alzheimer's disease: a review for clinical and research purposes

PURPOSE

This article presents a critical review of literature on dysgraphia associated with Alzheimer's disease (AD). Research presented includes discussions of central and peripheral spelling impairments as well as the impact of general, nonlinguistic cognitive functions on dysgraphia associated with AD.

METHOD

The studies critically reviewed were from a variety of disciplines, with emphasis on seminal work, recent literature, and the first author's research.

CONCLUSIONS

Studies have shown that writing impairment is heterogeneous within the AD population; however, there are certain aspects of the writing process that are more vulnerable than others and may serve as diagnostic signs. Identifying patterns of writing impairment at different stages of AD may help to chart disease progression and assist in the development of appropriate interventions.

Discourse comprehension test performance of elders with dementia of the Alzheimer type

Spoken language comprehension, including comprehension for inferential material in narrative discourse, is diminished in dementia of the Alzheimer type (DAT). There are, however, no empirical data concerning comprehension by adults with DAT of main ideas versus details in narratives. Evidence from other groups with and without brain damage has shown that comprehension for main ideas is relatively better than for details and that comprehension for stated material is relatively better than comprehension for inferential material. Participants in the present investigation were 24 older adults, 8 with early-stage DAT (EDAT), 8 with middle-stage DAT (MDAT), and 8 with no brain damage (NBD). Selected narratives and associated sets of yes-no questions from the Discourse Comprehension Test (DCT) (Brookshire and Nicholas, 1993) were presented on videotape. Participants with EDAT and MDAT had significantly poorer overall comprehension of DCT narratives than did those in the NBD group (p < .0001), but they did not differ significantly from each other. Responses to DCT narratives by participants in the NBD, EDAT, and MDAT groups followed the same pattern of relatively better comprehension for main ideas than for details and relatively better comprehension for stated than for implied information. Working memory and episodic memory were shown to be significantly associated with DCT overall scores. Together, these findings suggest that although overall narrative comprehension is diminished in those with DAT, individuals appear to retain a mental representation for narratives that facilitates better comprehension of main ideas than of details as well as better comprehension of stated information than of implied information. This interpretation is consistent with schema-based accounts of narrative comprehension.

A comparison of marital interaction patterns between couples in which the husband does or does not have Alzheimer's disease

Objectives. Our main purpose was to examine similarities and differences in patterns of interpersonal interaction between Alzheimer's disease (AD) caregiving and noncaregiving couples (n = 54). Methods. Twenty-seven wives caring for moderately impaired husbands with probable AD and 27 noncaregiving wives from comparable sociodemographic backgrounds were videotaped in their homes during both mealtime and a future event planning task. In addition, they completed self-report questionnaires to assess depression, stress, relationship mutuality, and perceived hope. Results. Compared with their counterparts, caregiving wives reported higher levels of depression and stress, but similar shared values and closeness. For the three factors developed from the Marital Interaction Coding System (MICS, version IV; Supportive Facilitative, and Rapport Building), a complex pattern of results was found in which disease status, type of task, and gender interacted significantly. Noncaregiving couples were more interactive overall and expressed more support to each other. Caregiving wives were found to be most facilitative during the planning task, whereas AD husbands were highest on interactions that built rapport (e.g., smiling) during that same task. Caregiving wives actually increased their facilitative behavior from the mealtime to planning task, probably reflecting the increased demand characteristics of the latter.

DISCUSSION

This study is one of a small body of literature to describe the negative impact of AD on spousal communication as observed and coded in two videotaped interaction situations in the home. Suggestions are made for future research, including the inclusion of longitudinal designs and non-Caucasian couples.

Communication from individuals with advanced DAT: can it provide clues to their sense of self-awareness and well-being?

Often communication from people with advanced dementia of the Alzheimer type (DAT) is regarded as incoherent and meaningless. However, with careful listening and observation, such communication often becomes more understandable. To better understand DAT communication, the investigators designed an exploratory qualitative study to videotape and critically analyze conversations between a clinical nurse specialist and 15 subjects with DAT ranging from mild to severe. One of the findings was that, even in later stages, indications were given that subjects had self-awareness of their cognitive decline. The investigators further examined the communication of the five most cognitively impaired subjects for other indications of self-awareness and well-being. To demonstrate this premise of awareness of cognitive decline and self in the later stages of DAT, excerpts from communication received from five subjects with advanced cognitive impairment are presented.

Alzheimer's disease and other dementias. Implications for physician communication

This article addresses the importance of language, speech, and communication accommodations between the physician and the patient with dementia. Following a brief summary of common profiles of speech, language, and communication in several different types of dementia, the authors discuss key elements based on a comprehensive model of communication enhancement for individuals with dementia. The primary emphasis of this article is that physicians must select individually tailored communication strategies drawn from a sound knowledge of patients' skills. More importantly, the article stresses that communication is not just the exchange of information, but communication includes components that help establish mutual respect and maintain patients' self-identity and autonomy.

Episodes of lucidity in people with severe dementia as narrated by formal carers

Twenty formal carers employed in three nursing homes narrated 92 episodes of lucidity (ELs) in people with severe dementia. Sixty-two episodes concerned speech, nine concerned actions and 21 episodes concerned both speech and actions. Most ELs were said to occur spontaneously when the patients were acting closely together with a carer who did not make demands on them and regarded them as valuable human beings whose behaviour was a meaningful expression of their experiences. The narrations showed characteristics that indicated trustworthiness and the episodes described in three separate nursing homes were very similar and resembled descriptions given in previous research reports as well as in relatives' reports. Further research seems necessary and the assumption that severe dementia implies the destruction of the self or personhood must be questioned.

Perseverative writing errors in a patient with Alzheimer's disease

This study reports the writing performance of a dysgraphic patient with Alzheimer's disease and moderate dementia who frequently perseverated on strokes and letters. Letter formation errors were also frequently produced. Oral spelling was superior to written spelling. The habitual style of writing (cursive writing) was significantly more prone to perseverations than writing in uppercase letters, a form of writing less frequently used by the patient. Central (linguistic) spelling processes were relatively preserved. The pattern of preserved and impaired functions is consistent with impairment of the peripheral mechanism that generates the graphic motor patterns code. We suggest that damage to the peripheral orthographic mechanism may cause deficits in some patients with Alzheimer's disease.

Relationship between bilingual demented immigrants and bilingual/monolingual caregivers

This study illuminates the relationship between bilingual demented patients and bilingual/monolingual caregivers during morning care sessions regarding the promotion of integrity in demented persons. Seven demented Finnish immigrants were videotaped during morning care together with bilingual and monolingual Swedish-speaking caregivers. A phenomenological-hermeneutic analysis of the videotapes was performed based on Ricoeur's philosophy. The structural analysis was made by means of the Erikson theory of "eight stages of man." Comparisons were made regarding demented immigrants' relationships with Swedish-Finnish speaking and Swedish speaking caregivers respectively. Three different patterns of relationship were seen: positive, negative, and mixed relationship. The study showed that bilingual caregivers' relationships with bilingual patients was positive or mainly positive (mixed), while the monolingual Swedish speaking caregivers had severe problems communicating with the same patients and therefore had more difficulties creating a positive relationship with them. It seems important that bilingual caregivers engage in the care of demented bilingual patients in order to help them use their latent competence and show themselves more clearly in the communication with their caregivers.
