A controlled study into the effects of psychoeducation for patients with cognitive disturbances

A clinical guide to assessment of navigation impairment: Standardized subjective and objective instruments and normative data

OBJECTIVE

Problems with finding one's way around are frequently reported by neurological patients. However, no dedicated standardized tools exist to assess whether such reports indicate navigation impairment or not. We provide a standardized three-step method to assess navigation ability in neurological patients, based on two recently developed diagnostic tools and normative data. The objective of this method is to assess navigation ability in detail, to allow for appropriate rehabilitation training for navigation impairment.

METHOD

A population-based sample of 7150 Dutch individuals (age 18-89) filled out the Wayfinding Questionnaire (WQ), to assess their self-reported navigation ability and level of spatial anxiety. Additionally, the participants completed the Leiden Navigation Test (LNT), a brief digital test consisting of five subtasks, assessing distinct domains of navigation ability. Both the WQ and LNT can be found online, free of charge.

RESULTS

Normative data stratified by gender and age are reported for each of the three subscales of the WQ, and for each of the five subtasks of the LNT.

CONCLUSIONS

Based on performance data of a very large population-based sample of participants, navigation performance of neurological patients with specific navigation complaints can be assessed in three steps. First, we recommend to inquire about potential problems concerning navigation. Next, in case of navigation complaints, the extent of potential navigation impairment can first be measured with the WQ. Lastly, if impaired scores are found, the LNT can provide objective verification of the perceived impairment, as well as insight into which navigation domains are affected. Such insight will allow for prediction of the practical consequences of the impairment and can be used for informed and tailored rehabilitation.

Distinctive neuropsychological profiles differentiate patients with functional memory disorder from patients with amnestic-mild cognitive impairment

OBJECTIVES

Patients with functional memory disorder (FMD) report significant memory failures in everyday life. Differentiating these patients from those with memory difficulties due to early stage neurodegenerative conditions is clinically challenging. The current study explored whether distinctive neuropsychological profiles could be established, suitable to differentiate patients with FMD from healthy individuals and those experiencing amnestic mild cognitive impairment (a-MCI).

METHODS

Patients with a clinical diagnosis of FMD were compared with patients with a-MCI, and healthy matched controls on several tests assessing different cognitive functions. Patients with clinically established mood disorders were excluded. Patients with FMD and a-MCI were broadly comparable on the level of their subjective memory complaints as assessed by clinical interview.

RESULTS

The neuropsychological profile of the FMD patients, although they expressed subjective memory and attention concerns during their clinical interview was distinct from patients with a-MCI on tests of memory [semantic fluency, age of acquisition (AoA) analysis of semantic fluency, verbal and non-verbal memory]. FMD patients did not differ significantly from healthy controls, but their scores on the letter fluency and digit cancellation tasks were not significantly different from those of the a-MCI patients indicating a possible sub-threshold deficit on these tasks.

CONCLUSION

Whilst subjective complaints are common within the FMD population, no objective impairment could be detected, even on a sensitive battery of tasks designed to detect subtle deficits caused by an early neurodegenerative brain disease. This study indicates that FMD patients can be successfully differentiated from patients with neurodegenerative memory decline by characterising their neuropsychological profile.

"Keep your brain fit!" Effectiveness of a psychoeducational intervention on cognitive functioning in healthy adults: A randomised controlled trial

A psychoeducational intervention (Keep your brain fit!) was designed for the middle-aged and older working population. The intervention focuses on increasing knowledge and awareness about cognitive ageing and teaching strategies to cope with cognitive changes. The primary aim of this study was to investigate the effectiveness of the e-health intervention in terms of subjective cognitive functioning. As secondary aims, objective cognitive functioning and psychological well-being were also measured. A randomised controlled trial that included people aged 40 to 65 years was conducted. A maximum of 4 weeks was allowed to complete the intervention. The outcome measures were obtained from an online test battery that was administered at baseline, post-test and at 4-week follow-up. A total of 376 participants completed the whole study. After the intervention, the experimental group reported more feelings of stability concerning memory functioning and perceived greater locus of control over memory compared to the control group. These effects were maintained at the 4-week follow-up. Taking into account the relatively low costs and easy accessibility of this e-health intervention, we consider the programme to be a valuable contribution to public healthcare interventions for middle-aged and older adults.

Effects of a comprehensive educational group intervention in older women with cognitive complaints: a randomized controlled trial

OBJECTIVE

This study presents a new comprehensive educational group intervention that offers psycho-education about cognitive aging and contextual factors (i.e., negative age stereotypes, beliefs, health, and lifestyle), focuses on skills and compensatory behavior, and incorporates group discussion. Its effects were investigated in community-dwelling older women who report normal age-related cognitive complaints.

METHODS

A randomized controlled trial with an experimental and waiting-list control condition was carried out in a sample of 50 women aged 60-75 years. As the main problem of these individuals were perceived cognitive deficits without actual cognitive decrements, metacognition served as the primary outcome measure.

OBJECTIVE

cognitive functioning and psychological well-being were secondary outcome measures. A double baseline and a follow-up assessment were carried out.

RESULTS

Participants in the experimental condition reported significantly fewer negative emotional reactions toward cognitive functioning (U = 164.500, p = 0.004). The reported effect size (δ = -0.473) could be interpreted as large.

CONCLUSIONS

This new comprehensive educational group intervention reduces negative emotional reactions toward cognitive functioning, which seems a prerequisite for improved subjective cognitive functioning and well-being. It can potentially contribute the well-being of an important and large group of older adults.

An evaluation of the use of a website and telephonic information service as public education about forgetfulness

There is increasing interest in telehealth as a potential new approach for healthcare delivery. To investigate whether telehealth is suitable to inform the older population about forgetfulness, we designed and compared two types of telehealth: Memory Website and the Memory Phone. The aim of this study was to analyze characteristics of the individuals who are interested in the Memory Phone and the Memory Website, to investigate the nature of the information in which the users were interested, and to evaluate the usefulness of the services. Participants were asked to answer several questions before and after visiting the main information menu of the telehealth facilities. Characteristics are given for all participants who used the facilities. In the evaluation period of 3 months, more individuals used the Memory Website (n = 2,631) than the Memory Phone (n = 228). The two services were used by different populations. Phone users were significantly older, more often female, and perceived themselves more often as forgetful. In the specific group of nonprofessional older individuals, general information about memory was more requested by Phone users compared with Website users (67% vs. 41%). Website users more often requested strategies and tips than Phone users (66% vs. 34%). The Phone and the Website were both considered useful. Overall, the Memory Website and the Memory Phone are two different types of evidence-based telehealth interventions, which are relevant for different populations, and are useful in informing the older population about forgetfulness and aging.

Effect of a structured course involving goal management training in older adults: A randomised controlled trial

OBJECTIVE

The objective of this study was to investigate the effects of a structured 6-week neuropsychological course on the executive functioning of older adults with cognitive complaints.

METHODS

A randomised controlled design was used involving 69 community dwelling individuals aged 55 years and older. Both objective and subjective measures were included to assess executive functioning. General linear model with repeated measures analysis of variance was used to examine the intervention effects.

RESULTS

After the intervention, the participants in the intervention group were significantly less annoyed by their cognitive failures, were better able to manage their executive failures and reported less anxiety symptoms than those in the waiting list control group.

CONCLUSION

These findings indicate that a combination of psycho-education and training has the potential to change the attitude of older individuals towards their cognitive functioning.

PRACTICE IMPLICATIONS

Because this training focussed on cognitive functions that are among the first to decline in older adults and the subjective evaluation of the people after training was quite favourable, the proposed intervention may be considered a valuable contribution to cognitive interventions for older adults.
