Recovery of content and temporal order memory for performed activities following moderate to severe traumatic brain injury

Few studies have investigated the complex nature of everyday activity memory following traumatic brain injury (TBI). This study examined recovery of content and temporal order memory for performed activities during the first year in individuals who suffered moderate to severe TBI. TBI and control participants completed eight different cognitive activities at baseline (i.e., acutely following injury for TBI) and then again approximately one year later (follow-up). Participants' free recall of the activities provided a measure of content memory. Temporal order memory was assessed with a reconstruction task. Self-report and informant report of everyday memory problems at follow-up were used to examine the relationship between activity memory performances and everyday memory. TBI participants showed significant recovery in both content and temporal order memory for activities during the first year. Despite showing significant recovery, the TBI group's activity memory performances remained poorer than that of controls at follow-up. Greater self- and informant report of everyday memory difficulties was associated with poorer temporal order memory but not content memory for activities. These findings demonstrate recovery in multiple memory processes that support activity memory following moderate to severe TBI. The findings also suggest a stronger link between everyday memory abilities and temporal order memory for activities than activity memory content in a TBI population.

Rehabilitation of everyday memory deficits in paediatric brain injury: Self-instruction and diary training

Memory problems that interfere with everyday living are frequently reported in children who have sustained acquired brain injury (ABI), but their nature and rehabilitation is under-researched. This study aimed to (1) determine neuropsychological correlates of everyday memory deficits in children with ABI, and (2) investigate the effectiveness of a newly developed programme for their rehabilitation. We assessed everyday memory, verbal memory, attention and behaviour in 15 children with ABI. The children attended the everyday memory rehabilitation programme: six weekly sessions that involved diary training, self-instruction training and case examples. At the onset we found that everyday memory problems were related to impaired attention and behavioural difficulties. On completion of the programme there was a significant increase in children's abilities to perform daily routines that demanded recall of information and events. In addition, children used diaries more frequently. Moreover, significant secondary gains were found in attention and mood (anxiety and depression). In conclusion, the results provided preliminary evidence that our six week programme could be effective in reducing everyday memory difficulties and improving psychological well-being in children with ABI.

Validation of a New Measure of Prospective Memory: The Royal Prince Alfred Prospective Memory Test

Prospective memory problems are common in patients with brain injury, but appropriate measures are limited. The reliability and validity of the newly designed Royal Prince Alfred Prospective Memory Test (RPA-ProMem), which has three alternate versions, was investigated in 20 healthy volunteers and 20 neurological patients with everyday prospective memory problems. The RPA-ProMem was found to be easy to score reliably (inter-rater reliability = .90) and its three versions were well matched (delayed alternate-form reliability = .71). Test validity and sensitivity to patient deficits were also supported. This new measure of prospective memory should be particularly useful in situations that require repeated assessments, such as evaluation of rehabilitation efforts.

Effects of testosterone and estrogen replacement on memory function

Testosterone insufficiency has been associated with psychosexual problems, reduced psychological well-being, and negative metabolic consequences, whereas less is known about the effects on cognition. The aim of this study was to investigate the effect of adding testosterone to estrogen therapy on memory functions in oophorectomized women. In a randomized, double-blind, placebo-controlled design, women with surgically induced menopause (n = 50; mean [SD] age, 54.0 [2.9] y) received estradiol valerate in combination with testosterone undecanoate or placebo. The women were assessed with a self-report questionnaire regarding memory and neuropsychological tests for verbal and spatial episodic memory and incidental learning at baseline, at the time of crossover, and after completion of treatment. Testosterone undecanoate 40 mg added to estrogen therapy had a negative effect on immediate but not delayed verbal memory at 24 weeks. Subjective and objective memory showed some correspondence as the women in the estrogen + placebo treatment group rated decreased everyday memory problems at 24 weeks compared with baseline. This was not observed in the women in the estrogen + testosterone treatment. Verbal attention span deteriorated from baseline with estrogen + placebo treatment but not with the estrogen + testosterone treatment. However, there was no significant treatment effect between the two groups. Adding testosterone to estrogen treatment deteriorated immediate verbal memory compared with estrogen + placebo, while other memory functions were unaffected.

Perceived causes of everyday memory problems in a population-based sample aged 39-99

There is usually a weak relation between memory complaints and laboratory memory performance, but few studies have investigated what people perceive as causes of their everyday memory problems. Thi ...

Episodic memory predictions in persons with amnestic and nonamnestic mild cognitive impairment

A performance-prediction paradigm was used to examine metamemory abilities in 27 individuals with amnestic mild cognitive impairment (MCI), 14 individuals with nonamnestic MCI, and 41 controls. To assess memory self-awareness, participants predicted the number of words they would remember before completing a list-learning memory task. Memory self-monitoring was evaluated by participants' ability to increase the accuracy of their predictions after experience with the list-learning task. As expected, participants with amnestic MCI demonstrated poorer memory abilities than the controls and participants with nonamnestic MCI. The amnestic MCI group also correctly predicted that they would recall less information than controls. Furthermore, both MCI groups showed accurate awareness of how differing task demands influence recall and successfully modified their memory predictions to be more accurate following task exposure. These findings revealed that individuals with amnestic and nonamnestic MCI were able to competently assess the demands of an externally driven metamemorial situation and utilize experience with a task to accurately update memory self-knowledge. Accurate metamemory skills may facilitate the ability of individuals with MCI to benefit from targeted behavioral interventions focused on utilizing compensatory strategies for everyday memory problems.

The AMQ: A Four‐Factor Inventory of Absentmindedness and Memory

The Absentmindedness and Memory Questionnaire (AMQ) is a new self-rating scale designed to evaluate everyday memory problems related to absentmindedness. It includes 24 items and is based on studies of different samples (N= 623). Its test-retest reliability is high and it has consistently shown similar factor structure. The AMQ thus measures four weakly correlated factors: Absentmindedness, Persons, Locations and Codes/Addresses. Factor analysis further indicates that Absentmindedness may include two subfactors: momentary attention deficit and prospective forgetfulness or impaired agenda memory. Gender differences were found in Persons (Female+) and Locations (Male+) but not in Absentmindedness or Codes/Addresses. The current version of AMQ has seven interindividually comparable response alternatives for each item in the questionnaire. This makes it useful as a measure of subjective absentmindedness or forgetfulness as well as a complementary measure of subjective memory for persons, locations, and codes/addresses/stories, especially at follow-up examinations.

Stress, Memory and Bosnian War Veterans

The aim of this study was to analyze cognitive dysfunction in PTSD. The testing included 79 Bosnian Army veterans, who participated in Bosnian war from 1992 to 1995. Out of 79 tested war veterans, 45 of developed PTSD while 34 did not. The veterans without PTSD where included in the control group. All the war veterans were of the same education level (secondary education) and between 30 and 50 years of age. Rivermead Behavioral Memory Test - RBMT was applied to all the subjects. The test was originally developed for the purpose of everyday memory problems identification. Clear goal of the 10 RBMT subtests is simulation of everyday life situations. PTSD group achieved significantly lower results than the control group. Results of the total score showed highly significant difference between PTSD and control group. Value of the t-test is t=10,056 with significance level of p<0,001. The same conclusion stands for any RBMT subtest. Numerous psychological studies on PTSD patients show more prominent psychological deficit in war veterans. Our study clearly confirms that finding.

Everyday cognitive failures and memory problems in Parkinson’s patients without dementia

There is growing evidence that Parkinson’s disease patients without dementia exhibit cognitive deficits in some executive, memory and selective attention tasks. However, the impact of these deficits on their everyday cognitive functioning remains largely unknown. This issue was explored using self-report questionnaires. Twenty-four Parkinson’s patients and 24 age-matched controls rated how frequently they make particular cognitive errors, such as forgetting what they were about to say. In addition, a partner or significant other also rated each participant’s propensity for making cognitive errors. Rather than simply rating themselves as making more of all types of errors, these results indicate that PD patients make more of specific types of error. Further analysis suggests that some of these errors are related to attentional processes (being more distractible) whereas others are related to retrieval processes (being unable to recall important details from the previous day).

Single case experimental design study of Carer facilitated Errorless Learning in a patient with severe memory impairment following TBI

To investigate if errorless learning applied by carer(s) in an everyday setting can reduce the frequency of everyday memory problems following severe traumatic brain injury (TBI). Multiple baseline single case experimental design. A patient with severe memory impairment, six years post TBI was recruited via an outpatient neurorehabilitation clinic. ABA analysis was conducted using daily frequency counts of everyday memory problems as an index of change. Errorless learning delivered by the patient's carer, aimed at reducing the occurrence of identified everyday memory problems. The carer was guided in treatment implementation by an Occupational Therapist. Incidence of frequently occurring memory lapses was significantly reduced (p< 0.001) and this was maintained at 3 months post intervention. This study highlights the potential clinical value of errorless learning with self-generated cues applied by carers within an everyday setting.

Towards memory supporting personal information management tools

AbstractIn this article, the authors discuss reretrieving personal information objects and relate the task to recovering from lapse(s) in memory. They propose that memory lapses impede users from successfully refinding the information they need. Their hypothesis is that by learning more about memory lapses in noncomputing contexts and about how people cope and recover from these lapses, we can better inform the design of personal information management (PIM) tools and improve the user's ability to reaccess and reuse objects. They describe a diary study that investigates the everyday memory problems of 25 people from a wide range of backgrounds. Based on the findings, they present a series of principles that they hypothesize will improve the design of PIM tools. This hypothesis is validated by an evaluation of a tool for managing personal photographs, which was designed with respect to the authors' findings. The evaluation suggests that users' performance when refinding objects can be improved by building personal information management tools to support characteristics of human memory.

Cognitive rehabilitation: assessment and treatment of persistent memory impairments following ECT

Few tests address the types of memory problem commonly reported after electroconvulsive therapy (ECT). Here, we focus on the importance of neuropsychological assessment in ECT-treated patients and describe a number of tasks that may be useful in measuring the everyday memory problems of such patients with ongoing memory difficulties. At the time of writing, no attempts have been made to rehabilitate patients who experience persistent adverse cognitive effects, but clinicians should be aware of the potential beneficial role of cognitive rehabilitation in the treatment and management of these effects.

The effects of cognitive teletherapy on reported everyday memory behaviours of persons with chronic traumatic brain injury

Primary objective: The purpose of this study was to evaluate the effects of an errorless training approach, Spaced Retrieval (SR) training delivered over the telephone, on the reported everyday memory problems of adults with chronic traumatic brain injury (TBI).Research design: The study was a randomized controlled clinical trial.Methods: Thirty-eight participants received either SR training or didactic strategy instruction (SI). Participants in both groups identified three memory-related goals and were paired to receive the same total telephone contact time. The main outcome measures were frequency of reported memory problems and perceived quality of life.Results: Participants in the SR group reported significantly more treatment goal mastery/strategy use than those in the SI group, immediately and at 1-month post-training. Caregivers reported similarly significant between-groups differences in everyday use of treatment behaviours at 1 month. Both groups reported some generalized strategy use to other non-targeted behaviours and decreased frequency of reported memory problems, but there were no significant between-groups differences in participant or caregiver reports of generalized strategy use or reported memory problems at either time-point. There was no change in perceived quality of life in either group.Conclusions: SR treatment delivered by phone produced significantly more treatment goal mastery/strategy use and maintenance than SI; however, both treatments improved reported everyday memory functioning for persons with TBI, without significant group differences on measures of generalized strategy use or perceived quality of life.

Cognitive rehabilitation of memory problems in patients with epilepsy

People with epilepsy often complain about their memory. Memory deficits are also most commonly observed during neuropsychological evaluation. Many patients with memory problems ask for some kind of memory training. General memory improvement is not possible, but learning mnemonics clearly will help to solve some of the most common everyday memory problems of patients. Most mnemonics follow the general rules for good learning or memory. In the design of a memory rehabilitation program some specific aspect should be taken into account, such as the need for psycho-education into the effects of cognitive deficits in daily life, the impact of personality and emotional reactions, and the individual perception of memory problems. Training goals must be tailor-made, small and as concrete as possible and fully adjusted to the needs and wishes of the patients. Generalization of the learned mnemonics is mostly modest or even absent.

Training compensatory memory strategies via the telephone for persons with TBI

Background: Spaced retrieval training has been used to teach individuals with dementia to use compensatory memory strategies. This training has been delivered over the telephone to some persons with dementia. Spaced retrieval applications for individuals with traumatic brain injury have not been reported to date.Aims: The purpose of this study was to investigate the efficacy of spaced retrieval for teaching individuals with traumatic brain injury strategies and facts via the telephone, with an emphasis on generalisation.Methods & Procedures: Seven participants with chronic everyday memory problems due to traumatic brain injury were trained to use memory aids for prospective and episodic memory tasks. Participants demonstrated borderline normal to mild global severity ratings. Functional memory problems were identified and external memory aids were provided if appropriate. Participants were trained using spaced retrieval via the telephone 30 minutes per day; each participant was trained on three memory goals. Participants and some caregivers reported strategy use and generalisation for most trained goals.Outcomes & Results: Results indicated that goal attainment and generalisation were achieved in an average of five 30-minute training sessions, resulting in 94.4% spaced-retrieval goal maintenance at 1 month. Strategy execution at 1 month was reported on 77.7% of goals trained.Conclusions: Spaced retrieval is a viable approach for training individuals with traumatic brain injury to use external memory aids and learn prospective memory tasks. Telephone intervention should be considered as an accessible service delivery alternative to promote generalisation with this population.

Cognitive and psychological predictors of everyday memory in children with intractable epilepsy

Children with epilepsy have known deficits on objective measures of learning and memory. Parents and children report that memory deficits have a negative impact on everyday functioning. In adults with epilepsy, self-report of memory is more strongly associated with depression than performance on memory tests. We investigated the cognitive and psychological predictors of everyday memory in 37 children with medically intractable epilepsy, using children's self-report and parent ratings of everyday memory performance and standard tests of attention, intelligence, visual and verbal memory, working memory, and mood/emotional state. Standard multiple regressions demonstrated that only a parent report measure of attention uniquely and significantly ( P⩽0.05) predicted estimates of everyday memory performance, accounting for 33% of variance in children's own ratings and 27% of variance in parents' ratings. Findings suggest that everyday memory in children with intractable epilepsy differs from that of adults; attentional problems may underlie everyday memory problems in these children.

Wechsler Memory Scale, Rivermead Behavioral Memory Test, and Everyday Memory Questionnaire in Healthy Adults and Alzheimer Patients

Summary: The Wechsler Memory Scale (WMS) is a laboratory-based memory test that has been criticized for its lack of ecological validity and for not testing long-term memory. A more recent memory test, which aims at testing everyday memory, is the Rivermead Behavioral Memory Test (RBMT); it tests prospective memory and other forms of memory not tapped by WMS. However, even this test does not capture all aspects of everyday memory problems often reported by adults. These problems are the object of the Everyday Memory Questionnaire (EMQ). This study aimed at identifying the relationships between these three memory tests. The differential effect of Alzheimer's disease (AD) on the above relationships was also studied. The sample consisted of 233 healthy adults (20 to 75+ years of age) and 39 AD patients (50 to 75 years of age). Confirmatory factor analysis revealed the following latent factors: Verbal Memory, Visual Reconstruction, Orientation, Message (action embedded in spatial context), Visual Recognition, Spatial Memory, New Learning/Association Forming, Prospective/Episodic Memory, and Metamemory. These first-order factors were further explained by two second-order factors: Semantic Memory and Coordination of Semantic and Visuo-Spatial Memory. This basic structure was preserved in the sample of AD patients, although AD patients performed less well on the WMS and the RBMT. Some interesting findings regarding semantic memory, face recognition, and metamemory in AD patients are also reported. Age, education, but no gender effects on memory performance were also detected.

Korean beliefs about everyday memory and aging for self and others.

Studies in the West have demonstrated that more everyday memory problems are expected for typical older adults than for typical young adults. In order to examine memory beliefs about aging in Asia, we conducted a study in Korea which parallels that of Ryan and Kwong See (1993). We used the three self-efficacy scales of the Metamemory in Adulthood instrument (Dixon & Hultsch, 1983) to determine whether age changes are anticipated for oneself as well as for typical adults. Young adults (N = 468; mean age = 21.0 years) rated the memory of either typical adults (aged 25, 45, or 65 years) or themselves at one of these ages. As in Ryan and Kwong See (1993), anticipation of decline was obtained on two of the three self-efficacy scales (i.e., capacity and change). In addition, beliefs about everyday memory decline (i.e., capacity and locus) were weaker for the self than for typical others. Hence, support was obtained for negative stereotypes about memory and aging in Korea as well as a self-protection bias indicating stronger anticipation of age-related decline among others.
