Validation of the Affective Word List as a measure of verbal learning and memory

Introduction: This study evaluated the Affective Word List (AWL), a measure designed to assess affective bias, as a measure of verbal learning and memory in the context of baseline concussion evaluations. The AWL was developed to assess affective bias in order to circumvent the tendency of some examinees to minimize self-report of depression symptoms. However, because it is designed as a traditional list-learning task, the cognitive indices of the AWL have the added potential to be used as measures of verbal learning and memory. It would be useful to have a performance-based measure that is sensitive to both the affective and cognitive consequences of concussion. Method: Participants from a university-based sports concussion program were used to evaluate the descriptive statistics and distribution of the AWL and its convergent and discriminant validity. A separate sample of undergraduate students, active in intramural or club athletics, served as participants for a delayed alternate-form reliability study. All reliability and validity results were compared with those of the Hopkins Verbal Learning Test–Revised (HVLT–R) and the Immediate Post-Concussion Assessment and Cognitive Testing Verbal Memory Composite (ImPACT-VM). Results: Results of this study showed that the cognitive indices of the AWL have normal distributions, and its four forms are equivalent. The AWL demonstrated moderate delayed alternate-form reliability, moderate convergent validity with other measures of verbal learning and memory, and strong discriminant validity with measures of processing speed and reaction time. Conclusions: Results of this study suggest that the AWL may have clinical utility as a measure of verbal learning and memory in concussion management and research.

The impact of cognitive impairment, neurological soft signs and subdepressive symptoms on functional outcome in bipolar disorder

BackgroundCognitive impairments and subsyndromal depressive symptoms are present during euthymic periods of bipolar disorder (BD). Most studies have determined that cognitive impairments and residual depressive symptoms have major impacts on psychosocial functioning. The aim of the present study was to identify the major factor responsible for low psychosocial functioning in a subgroup of patients with BD despite clinical recovery. MethodsSixty patients with bipolar I disorder and 41 healthy subjects were enrolled in this study. Cognitive performance, neurological soft signs (NSSs), psychosocial functioning, residual mood symptoms and illness characteristics were assessed. Using the median value of the Functioning Assessment Short Test (FAST) as the cut-off point, the patients were divided into two groups, high- (n=29) or low-functioning (n=31), and they were compared based on total NSS, residual depressive symptoms, cognitive performance and clinical variables. ResultsPerformances on the verbal memory tests and social functioning were significantly worse in the euthymic patients with BD. Increased rates of NSS were identified in the patients compared with the normal controls. The low-functioning patients performed significantly worse on verbal memory, and their NSS and residual depressive symptoms were significantly higher compared to high-functioning patients. In the regression analysis, subsyndromal depressive symptoms and verbal learning measures were identified as the best predictors of psychosocial functioning. LimitationsThe patients were artificially separated into two groups based on a FAST score cut-off. ConclusionsIn this study, residual depressive symptoms and verbal memory impairments were the most prominent factors associated with the level of functioning.

The dangers of failing one or more performance validity tests in individuals claiming mild traumatic brain injury-related postconcussive symptoms.

Evaluating performance validity is important in any neuropsychological assessment, and prior research recommends a threshold for invalid performance of two or more performance validity test (PVT) failures. However, extant findings also indicate that failing a single PVT is associated with significant changes in neuropsychological performance. The current study sought to determine if there is an appreciable difference in neuropsychological testing results between individuals failing different numbers of PVTs. In a sample of veterans with reported histories of mild traumatic brain injury (mTBI; N =178), analyses revealed that individuals failing only one PVT performed significantly worse than individuals failing no PVTs on measures of verbal learning and memory, processing speed, and cognitive flexibility. Additionally, individuals failing one versus two PVTs significantly differed only on delayed free recall scores. The current findings suggest that failure of even one PVT should elicit consideration of performance invalidity, particularly in individuals with histories of mTBI.

Relationships between tumor grade and neurocognitive functioning in patients with glioma of the left temporal lobe prior to surgical resection.

Various tumor characteristics have been associated with neurocognitive functioning (NCF), though the role of tumor grade has not been adequately examined. Seventy-two patients with histologically confirmed grade IV glioma (n = 37), grade III glioma (n = 20), and grade II glioma (n = 15) in the left temporal lobe completed preoperative neuropsychological assessment. Rates of impairment and mean test performances were compared by tumor grade with follow-up analysis of the influence of other tumor- and patient-related characteristics on NCF. NCF impairment was more frequent in patients with grade IV tumor compared with patients with lower-grade tumors in verbal learning, executive functioning, as well as language abilities. Mean performances significantly differed by tumor grade on measures of verbal learning, processing speed, executive functioning, and language, with the grade IV group exhibiting worse performances than patients with lower-grade tumors. Group differences in mean performances remained significant when controlling for T1-weighted and fluid attenuated inversion recovery MRI-based lesion volume. Performances did not differ by seizure status or antiepileptic and steroid use. Compared with patients with grade II or III left temporal lobe glioma, patients with grade IV tumors exhibit greater difficulty with verbal learning, processing speed, executive functioning, and language. Differences in NCF associated with glioma grade were independent of lesion volume, seizure status, and antiepileptic or steroid use, lending support to the concept of "lesion momentum" as a primary contributor to deficits in NCF of newly diagnosed patients prior to surgery.

Investigation of menopausal stage and symptoms on cognition in human immunodeficiency virus-infected women.

We evaluated the separate and interactive associations of menopausal stage, menopausal symptoms, and human immunodeficiency virus (HIV) infection with cognition. We hypothesized that HIV-infected perimenopausal women would show the greatest cognitive difficulties and that menopausal symptoms would be inversely associated with cognition. This cross-sectional study included 708 HIV-infected and 278 HIV-uninfected premenopausal, perimenopausal, or postmenopausal women (64% African American; median age, 44 y) from the Women's Interagency HIV Study. Participants completed tests of verbal learning and memory, attention/processing speed, and executive function. We administered a menopausal symptom questionnaire that assessed anxiety, vasomotor, and sleep symptoms and obtained measures of depressive symptoms. In multivariable regression analyses controlling for relevant covariates, HIV infection, but not menopausal stage, was associated with worse performance on all cognitive measures (P's < 0.05). Depressive symptoms were associated with lower cognitive performance on measures of verbal learning and memory, attention, and executive function (P's < 0.05); anxiety symptoms were associated with lower performance on measures of verbal learning and memory (P's < 0.05). Vasomotor symptoms were associated with worse attention (P < 0.05). HIV and anxiety symptoms interacted to influence verbal learning (P's < 0.05); elevated anxiety was associated with worse verbal learning in HIV-infected women only. Vasomotor, depressive, and anxiety symptoms, but not menopausal stage, are associated with worse cognitive performance in both HIV-infected and HIV-uninfected women, although elevated anxiety symptoms are more associated with verbal learning deficits in HIV-infected women. Because cognitive problems can interfere with everyday functioning, including treatment adherence, it may be important to screen and treat anxiety in HIV-infected women.

BASELINE DEPRESSIVE SYMPTOMS ARE PREDICTIVE OF PROGRESSION TO CLINICAL DEMENTIA AT 5 YEARS: A COMMUNITY-BASED STUDY IN CHINESE OLDER ADULTS (HONG KONG MEMORY AND AGEING PROSPECTIVE STUDY, HK-MAPS)

0.8%), had depression (47.4% versus 29.6%), experienced hallucinations (21.8% versus 0.5%), had REM sleep behavior disorder (18.1% versus 0.6%), and had earlier cognitive decline onset (mean: 66.1 years vs 72.5 years old). In multivariable analysis, MCI-PD subjects performed significantly better than MCI-AD subjects on the MMSE total, both UDS memory tests, all three UDS language tests, and one of the attention tests. There were no significant differences when comparing scores on the MMSE pentagon (visuospatial) test, the second attention test, or the three executive function tests.Conclusions:MCI-PD and MCI-AD subjects differed on multiple demographic and clinical characteristics. MCI-PD subjects scored better on the UDS measures of verbal learning, semantic fluency, and naming, and there were no significant differences in the groups on UDS measures of visuospatial ability, executive function, and processing speed. The UDS sample of MCI-PD subjects provides an opportunity for future study of multiple domain, amnestic MCI, a less common presentation of MCI-PD.

The American Heart Association Life's Simple 7 and Incident Cognitive Impairment: The REasons for Geographic And Racial Differences in Stroke (REGARDS) Study

BackgroundLife's Simple 7 is a new metric based on modifiable health behaviors and factors that the American Heart Association uses to promote improvements to cardiovascular health (CVH). We hypothesized that better Life's Simple 7 scores are associated with lower incidence of cognitive impairment.Methods and ResultsFor this prospective cohort study, we included REasons for Geographic And Racial Differences in Stroke (REGARDS) participants aged 45+ who had normal global cognitive status at baseline and no history of stroke (N=17 761). We calculated baseline Life's Simple 7 score (range, 0 to 14) based on smoking, diet, physical activity, body mass index, blood pressure, total cholesterol, and fasting glucose. We identified incident cognitive impairment using a 3‐test measure of verbal learning, memory, and fluency obtained a mean of 4 years after baseline. Relative to the lowest tertile of Life's Simple 7 score (0 to 6 points), odds ratios of incident cognitive impairment were 0.65 (0.52, 0.81) in the middle tertile (7 to 8 points) and 0.63 (0.51, 0.79) in the highest tertile (9 to 14 points). The association was similar in blacks and whites, as well as outside and within the Southeastern stroke belt region of the United States.ConclusionsCompared with low CVH, intermediate and high CVH were both associated with substantially lower incidence of cognitive impairment. We did not observe a dose‐response pattern; people with intermediate and high levels of CVH had similar incidence of cognitive impairment. This suggests that even when high CVH is not achieved, intermediate levels of CVH are preferable to low CVH.

Verbal learning deficits in posttraumatic stress disorder and depression.

Verbal learning and memory deficits are frequently reported in posttraumatic stress disorder (PTSD), but may be a product of its psychiatric comorbidities, especially major depressive disorder (MDD). To evaluate this hypothesis, 25 medication-free patients with PTSD and comorbid MDD were compared to 148 medication-free patients with equally severe MDD alone and to 96 nonpatients on a measure of verbal learning and memory. Additional measures of attention, working memory, and executive function were administered to evaluate their contribution to verbal memory impairment. Patients with comorbid PTSD and MDD demonstrated the greatest deficit in verbal learning compared to both MDD patients and nonpatients (omnibus effect sizes ranged d = 0.41 to 0.50), one that was not accounted for by other cognitive deficits. Findings suggest that a current diagnosis of PTSD makes a contribution to verbal learning deficits beyond the effect of depression alone.

Association of Age at Depression Onset with Cognitive Functioning in Individuals with Late-Life Depression and Executive Dysfunction

To compare patterns of cognitive performance in older adults with late-onset depression (LOD;≥65 years of age) with that of older adults with early-onset depression (EOD;<65 years). Participants were 171 adults aged 60 years or older with major depression and executive dysfunction who were participating in a randomized psychotherapy trial. Participants included 72 LOD and 99 EOD individuals. Cognitive performance on measures of verbal learning, memory, and executive functioning were evaluated. Demographic and clinical characteristics, severity of cerebrovascular risk factors, and disability ratings were also compared between groups. The LOD group was older and had fewer previous episodes of depression and lower severity of depression compared with EOD participants. The LOD group demonstrated poorer performance on measures of verbal learning (F(1,161)= 4.28, p= 0.04) and memory (F(1,160)= 4.65, p= 0.03) than the EOD group. Linear regression analysis demonstrated that LOD and fewer years of education were significant predictors of poorer verbal learning (F(7,114)= 6.25, p<0.001) and memory (F(7,113)=7.24, p<0.001). Performance on measures of executive functioning, severity of vascular risk factors, and disability ratings did not differ between the two groups. In older adults with depression and executive dysfunction, LOD was associated with poorer performance on measures of verbal learning and memory. Aging-related brain changes associated with LOD may play a more important role, leading to dysfunction in these cognitive domains than a history of recurrent depressive episodes in older adults with a dysexecutive syndrome.

Effect of head impacts on diffusivity measures in a cohort of collegiate contact sport athletes

To determine whether exposure to repetitive head impacts over a single season affects white matter diffusion measures in collegiate contact sport athletes. A prospective cohort study at a Division I NCAA athletic program of 80 nonconcussed varsity football and ice hockey players who wore instrumented helmets that recorded the acceleration-time history of the head following impact, and 79 non-contact sport athletes. Assessment occurred preseason and shortly after the season with diffusion tensor imaging and neurocognitive measures. There was a significant (p = 0.011) athlete-group difference for mean diffusivity (MD) in the corpus callosum. Postseason fractional anisotropy (FA) differed (p = 0.001) in the amygdala (0.238 vs 0.233). Measures of head impact exposure correlated with white matter diffusivity measures in several brain regions, including the corpus callosum, amygdala, cerebellar white matter, hippocampus, and thalamus. The magnitude of change in corpus callosum MD postseason was associated with poorer performance on a measure of verbal learning and memory. This study suggests a relationship between head impact exposure, white matter diffusion measures, and cognition over the course of a single season, even in the absence of diagnosed concussion, in a cohort of college athletes. Further work is needed to assess whether such effects are short term or persistent.

Cognition in perimenopause

The aims of this cross-sectional study were to determine if cognitive function differs across stages of reproductive aging and to evaluate whether hormones or menopausal symptoms predict cognition in perimenopause. We hypothesized that women in late menopausal transition and early postmenopause would perform more poorly than those in the late reproductive stage on attention and verbal memory tasks, and that estradiol, depressive symptoms, anxiety symptoms, hot flashes, and sleep disturbance would predict cognitive performance on those tasks. One hundred seventeen middle-aged women enrolled in the Rochester Investigation of Cognition Across Menopause were categorized into late reproductive stage (n = 34), early menopausal transition stage (n = 28), late menopausal transition stage (n = 41), or early postmenopause stage (n = 14) according to criteria from the Stages of Reproductive Aging Workshop +10. We administered a neuropsychological battery assessing six domains of cognition, assessed menopausal symptoms, and measured serum levels of estradiol and follicle-stimulating hormone. Multivariate regressions were conducted to determine the impact of menopausal stage and symptoms on cognition. Women in the first year of postmenopause performed significantly worse than women in the late reproductive and late menopausal transition stages on measures of verbal learning, verbal memory, and motor function. They also performed significantly worse than women in the late menopausal transition stage on attention/working memory tasks. Cognitive function does not change linearly across perimenopause. Decreases in attention/working memory, verbal learning, verbal memory, and fine motor speed may be most evident in the first year after the final menstrual period.

Are Cardiovascular Risk Factors Associated with Verbal Learning and Memory Impairment in Patients with Schizophrenia? A Cross-Sectional Study

Objective. The aim of this study is to assess the relationships of cardiovascular risk factors with verbal learning and memory in patients with schizophrenia. Methods and Design. cross-sectional study. Inclusion Criteria. Diagnosis of schizophrenia according to the DSM-IV-TR criteria. Data Collection. Sociodemographic information, clinical characteristics, anthropometric measurements, blood tests, and episodic memory using the California Verbal Learning Test (CVLT). Analysis. A multivariate analysis using multiple linear regressions was performed to determine variables that are potentially associated with verbal learning and memory. Results. One hundred and sixty-eight outpatients participated in our study. An association was found between the metabolic syndrome (MetS) and memory impairment on measures of verbal learning, and short- and long-term memory. Among the different components of MeTS, hypertriglycerides, abdominal obesity, and low HDL cholesterol were the only factors associated with memory impairment. Alcohol dependence or abuse was associated with a higher rate of forgetting. Conclusion. Our findings suggest that MetS and alcohol use may be linked with memory impairment in schizophrenia. These findings provide important insights into the interdependencies of cardiovascular risk factors and cognitive disorders and support novel strategies for treating and preventing cognitive disorders in patients with schizophrenia.

Development of normative neuropsychological performance in Thailand for the assessment of HIV-associated neurocognitive disorders

International studies of HIV-associated neurocognitive disorder (HAND) are needed to determine the viral and host factors associated with cognitive impairment particularly as more than 80% of HIV+ subjects reside in resource-limited settings. Recent diagnostic nomenclature of HAND requires comparison of cognitive performance specifically to local normative data. To evaluate this need for local norms, we compared normative data obtained locally in Thailand to Western norms. The current study examined cognitive performance in 477 seronegative Thai participants (male = 211, female = 266) who completed a battery of tests sensitive to cognitive changes in HIV. The cohort was divided into three age brackets (20–34; 35–49; 50–65 years) and four educational levels (no education or primary education, less than secondary certificate, high-school/associates degree, bachelor's degree or greater). The Thai cohort was compared (using analysis of covariance, ANCOVA) on a number of measures to a seronegative US cohort (n = 236; male = 198, female = 38) to examine cultural differences in performance. Normative data are provided with age and education stratification. The Thai and US groups performed significantly differently on all neuropsychological measures with the exception of verbal fluency. The Thai group performed better on measures of verbal learning (p < .001) and memory (p < .001) and measures of psychomotor speed (p < .001). Education was a more powerful predictor of performance in the Thai cohort than in the US group. These results highlight the continued need for the development of normative data within local populations. The use of Western norms as a comparison group could lead to inaccurate identification of HAND in culturally distinct groups.

Accelerated long‐term forgetting in children with idiopathic generalized epilepsy

The rapid forgetting of information over long (but not short) delays (accelerated long-term forgetting [ALF]) has been associated with temporal lobe epilepsy but not idiopathic generalized epilepsy (IGE). Long-term memory formation (consolidation) is thought to demand an interaction between medial temporal and neocortical networks, which could be disrupted by epilepsy/seizures themselves. The present study investigates whether ALF is present in children with IGE and whether it relates to epilepsy severity. Sixty-one children (20 with IGE and 41 healthy controls [HC]) of comparable age, sex, and parental socioeconomic status completed neuropsychological tests, including a measure of verbal learning and recall after, short (30-min) and long (7-day) delays, and recognition. Epilepsy severity was rated by treating neurologists. A two-way repeated measures analysis of covariance (ANCOVA) found a significant Group x Delay interaction; the children with IGE recalled (and recognized) significantly fewer words after a long, but not short (2- and 30-min) delay relative to the HC children. Moreover, greater epilepsy severity was associated with poorer recognition. This study demonstrates, to our knowledge for the first time, that children with IGE present with ALF, which is related to epilepsy severity. These findings support the notion that epilepsy/seizures themselves may disrupt long-term memory consolidation, which interferes with day-to-day functioning of children with IGE.

Repeated neuropsychological assessment in well-controlled epilepsy

The majority of patients with epilepsy are seizure-free, and repeated neuropsychological assessment may be highly relevant in this group. However, previous studies have not addressed the possible influence of important clinical variables on repeated neuropsychological assessment in this population. Using data from a large antiepileptic drug (AED) withdrawal study, we calculated the neuropsychological practice effects for 139 seizure-free patients with epilepsy and analysed the influence of different epilepsy-related factors on improvement that were observable 7 months after the initial neuropsychological assessment. A clear and significant improvement in neuropsychological test performance was found for all the tests employed, regardless of AED withdrawal. Furthermore, patients characterized by evidence of brain pathology, such as known cerebral aetiology, pathological MRI and pathological EEG, showed less practice effects than patients not characterized by these variables. The differences were primarily evident for measures of verbal learning and memory. The data obtained from this study suggest that the development of general norms for change in the particular patient population, as well as specific norms for change related to important clinical variables, might be necessary to be able to determine whether genuine neuropsychological changes have occurred in individual patients in this group.

Cognitive features 10 or more years after successful breast cancer survival: comparisons across types of cancer interventions

The present study examined the long-term cognitive implications of cancer treatment among breast cancer survivors aged 65 years and older to better understand the long term implications of cancer treatment. Fifty-seven women survivors were compared with 30 healthy older female adult comparisons, matched in terms of age and education, with no history of cancer. Cancer survivors were also compared on the basis of treatment intervention, involving chemotherapy (n = 27) versus local therapy through surgery and radiation (n = 30). As a group, the breast cancer survivors scored lower on measures of general cognitive function, working memory, psychomotor speed, and executive function when compared with the normal comparisons. Among the cancer survivors, those who received local therapy scored lower than the other survivors and normal comparisons on measures of verbal learning, visual perception and construction, as well as visual attention and short-term retention. Our findings suggest that cognitive outcomes may involve greater age-related deficits among older cancer survivors compared with matched healthy subjects.

Undetected Cognitive Impairment and Decision-Making Capacity in Patients Receiving Hospice Care

: Cognitive dysfunction is common in patients with advanced, life-threatening illness and can be attributed to a variety of factors (e.g., advanced age, opiate medication). Such dysfunction likely affects decisional capacity, which is a crucial consideration as the end-of-life approaches and patients face multiple choices regarding treatment, family, and estate planning. This study examined the prevalence of cognitive impairment and its impact on decision-making abilities among hospice patients with neither a chart diagnosis of a cognitive disorder nor clinically apparent cognitive impairment (e.g., delirium, unresponsiveness). : A total of 110 participants receiving hospice services completed a 1-hour neuropsychological battery, a measure of decisional capacity, and accompanying interviews. : In general, participants were mildly impaired on measures of verbal learning, verbal memory, and verbal fluency; 54% of the sample was classified as having significant, previously undetected cognitive impairment. These individuals performed significantly worse than the other participants on all neuropsychological and decisional capacity measures, with effect sizes ranging from medium to very large (0.43-2.70). A number of verbal abilities as well as global cognitive functioning significantly predicted decision-making capacity. : Despite an absence of documented or clinically obvious impairment, more than half of the sample had significant cognitive impairments. Assessment of cognition in hospice patients is warranted, including assessment of verbal abilities that may interfere with understanding or reasoning related to treatment decisions. Identification of patients at risk for impaired cognition and decision making may lead to effective interventions to improve decision making and honor the wishes of patients and families.

Age-Associated Differences in Cognitive Performance in Older Patients With Schizophrenia: A Comparison With Healthy Older Adults

There are varying results regarding the conjoint influence of aging and schizophrenia on cognitive abilities. Previous studies have been limited by restricted age ranges among schizophrenia and psychiatrically healthy control samples as well as small numbers of control participants. To quantify the association between age and cognitive performance in patients with schizophrenia and psychiatrically healthy older adult controls and to determine if age-associated changes in cognitive performance were different in the two groups. People with schizophrenia (n = 226) and psychiatrically healthy individuals (n = 834) ranging in age from 40 to older than 80 years were compared on a battery of neuropsychological tests. To directly compare the impact of age on cognitive performance, age was also regressed on performance in the two samples. The performance of psychiatrically healthy adults age 70 and older was superior to the performance of the youngest patients with schizophrenia (age 40-49) years on measures of working and episodic memory, executive function, and psychomotor speed. Regression analyses indicated that age effects on cognition were significantly greater for schizophrenia patients on measures of verbal learning and speed of processing. Within both the schizophrenia group, and psychiatrically healthy adults, the greatest age-related differences in performance seemed to occur for individuals aged more than 70 years. In this cross-sectional study, the present findings underscore the fact that schizophrenia is associated with cognitive impairment across all ages and that older schizophrenia patients experience relatively greater age associated differences in cognitive functioning than healthy individuals. These findings have wide-ranging implications regarding the ability of older patients with schizophrenia to function independently and for the development of treatment strategies.

Cognitive plasticity in normal and pathological aging

The main goal of the present study is to examine to what extent age and cognitive impairment contribute to learning performance (cognitive plasticity, cognitive modifiability, or learning potential). To address this question, participants coming from four studies (Longitudinal Study of Active Aging, age range, 55–75 years, N = 458; Longitudinal Study in the very old [90+], age range, 90–102, N = 188, and Cognitive Plasticity within the Course of Cognitive Impairment, 97 “Normal”, 57 mild cognitive impairment [MCI], and 98 Alzheimer’s disease [AD] patients) were examined through a measure of verbal learning (developed from Rey). The results show that all age, MCI, and AD groups learned across the five learning trials of that test, but significant differences were found due to age, pathology, and education. The effects of pathology (MCI and AD) can be expressed in a metric of “years of normal decline by age”; specifically, being MCI means suffering an impairment in performance that is equivalent to the decline of a normal individual during 15 years, whereas the impact of AD is equivalent to 22.7 years. Likewise, the improvement associated with about 5 years of education is equivalent to about 1 year less of normal aging. Also, the two pathological groups significantly differed from “normal” groups in the delayed trial of the test. The most dramatic difference is that between the “normal” group and the AD patients, which shows relatively poorer performance for the AD group in the delayed trial than in the first learning trial. The potential role of this unique effect for quick detection purposes of AD is assessed (in the 75–89 years age range, sensitivity and specificity equal 0.813 and 0.917, respectively).

Preliminary Data on the Effect of Culture on the Assessment of Alzheimer's Disease-Related Verbal Memory Impairment with the International Shopping List Test

The International Shopping List Test (ISLT) is a measure of verbal learning and memory, developed specifically for use in people from different cultural and linguistic backgrounds. In this report, we describe two studies that examined the ISLT's ability to detect memory impairment and memory decline in patients with mild Alzheimer's disease (AD) from a range of cultural and linguistic backgrounds. In Study 1, the performance of Australian-English-speaking adults with mild AD was compared with that of native Australian-English- and Korean-speaking patients with mild AD. Compared with controls, patients with AD from both language groups showed large but equivalent impairments in total recall, delayed recall, rate of learning, and primacy and retention-weighted recall (RWR) measures on the ISLT. In Study 2, the rate of deterioration in verbal memory over 1 year was examined in groups of native Canadian-English, French, and Korean speakers with mild AD using the total recall, delayed recall, and RWR measures. Rates of change on all three measures were equivalent across the language groups, although the magnitude of deterioration was most pronounced for the total recall and RWR measures. Taken together, these results suggest that the ISLT is valid and reliable for the assessment of verbal learning and memory impairment and decline in patients with mild AD from diverse language groups.
