Interrelation of striatal dopamine, brain metabolism and cognition in dementia with Lewy bodies.

Dementia with Lewy bodies (DLB), the second most common neurodegenerative dementia, is characterized by cognitive decline, fluctuation of cognition and alertness, visual hallucinations, rapid eye movement sleep behaviour disorder and parkinsonism. Imaging biomarkers are of great importance in diagnosing patients with DLB and associated with characteristic clinical features including cognitive decline. In this study, we investigate interrelation between nigrostriatal dopamine depletion, brain metabolism and cognition in DLB. We enrolled 55 patients with probable DLB (15 with prodromal DLB and 40 with DLB) and 13 healthy controls. All subjects underwent N-(3-[18F]fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane PET/CT, 18F-fluorodeoxyglucose PET/CT, 18F-florbetaben PET/CT and detailed neuropsychological testing. The relationship between striatal dopamine transporter availability and regional brain metabolism was assessed using general linear models, and the effect of striatal dopamine transporter availability and brain metabolism on specific cognitive function was evaluated by multivariate linear regression analysis. Path analyses were used to evaluate the relationship between striatal dopamine transporter availability, fluorodeoxyglucose uptake and cognitive function scores. Additionally, a linear mixed model was used to investigate the association between baseline dopamine transporter availability or brain metabolism and longitudinal cognitive decline. Independent of amyloid deposition, caudate and putamen dopamine transporter availabilities were positively correlated with brain metabolism in the DLB-specific hypometabolic regions, most prominently in the occipital and lateral parietal cortices. Both reduced caudate dopamine and brain hypometabolism were associated with low z-scores of Rey-Osterrieth Complex Figure Test copy, Seoul Verbal Learning Test immediate recall and Controlled Oral Word Association Test (COWAT)-animal. Path analyses showed that the effect of reduced caudate dopamine on the Rey-Osterrieth Complex Figure Test copy z-score was completely mediated by brain hypometabolism, whereas it affected the Seoul Verbal Learning Test immediate recall z-score both directly and via the mediation of brain hypometabolism. Caudate dopamine depletion was directly associated with the COWAT-animal z-score, not mediated by brain hypometabolism. Both baseline caudate dopamine transporter availability and brain hypometabolism were associated with longitudinal cognitive decline, with brain hypometabolism being more relevant. Our findings suggest that in DLB, striatal dopaminergic depletion and brain hypometabolism are closely related, and they differentially affect cognitive dysfunction in an item-specific manner. Additionally, brain hypometabolism would be more relevant to longitudinal cognitive outcomes than striatal dopaminergic degeneration.

The Impact of Hearing Loss and Hearing Aid Usage on the Visuospatial Abilities of Older Adults in a Cohort of Combined Hearing and Cognitive Impairment.

IntroductionIt has been proposed that hearing loss may result in improved visuospatial abilities. The evidence for this assertion is inconsistent, and limited to studies in congenitally deaf children, despite older adults with age-related hearing loss constituting the vast majority of the hearing impaired population. We assessed visuospatial (visuoconstruction and visuospatial memory) ability in older adult hearing aid users with and without clinically significant cognitive impairment. The primary aim of the study was to determine the effect of hearing loss on visuospatial abilities.MethodSeventy-five adult hearing aid users (HA) aged over 65 were recruited, out of whom 30 had normal cognition (NC-HA), 30 had mild cognitive impairment (MCI-HA), and 15 had dementia (D-HA). The Rey Osterrieth Complex figure test (ROCFT) copy, 3 min recall and 30 min recall tests were performed to evaluate the visuoconstructional and visuospatial memory abilities of the participants.ResultsThere were significant differences between the ROCFT copy, 3 min recall, and 30 min recall among the three cohorts (p < 0.005). Compared with previously published normative data, the NC-HA performed significantly better in the ROCFT copy (p < 0.001), immediate recall (p < 0.001), and delay recall (p = 0.001), while the MCI-HA performed similarly to the expected norms derived from population (p = 0.426, p = 0.611, p = 0.697, respectively), and the D-HA performed below this norm.ConclusionThough visuospatial abilities tend to decline when the global cognitive functioning declines, we found suggestive evidence for positive effects of age-related hearing loss on visuospatial cognitive ability. Participants with mild cognitive impairment and hearing loss, who would have been expected to perform worse than normative data, were in fact performing as well as cognitively healthy subjects without hearing loss. Visuospatial ability could be targeted when providing rehabilitation for the older adults with hearing loss.

The Savage Organizational Scoring System for the Rey-Osterrieth Complex Figure Test: Norms and New Data From Veterans in a Traumatic Brain Injury Clinic.

The Rey-Osterrieth Complex Figure Test (RCFT) permits quantifying diverse cognitive abilities, including executive function (EF). We evaluated the psychometric properties of a scoring procedure for the RCFT, the Savage Organizational Scoring System (SOSS), that awards points for drawing the largest structural elements of the figures as continuous wholes. This was a two-phase study: first, we conducted a systematic literature search for studies using the SOSS, and aggregated previously published data for healthy controls to create a normative database; second, we observed performances from veterans evaluated for traumatic brain injury (TBI), examining the reliability of their SOSS scores, the SOSS correlations with two EF measures and the participants' self-reported cognitive functioning, and then compared their mean scores to normative expectations. Across our literature-derived normative database, the aggregated mean SOSS score was 4.12 (SD = 1.72), which was marginally higher than that of our veteran participants evaluated for TBI, 3.72 (SD = 1.79). The SOSS had modest internal consistency (α = .59). Unlike the criterion EF measures, the SOSS was not significantly related to self-reported cognitive functioning. The SOSS shared a small, significant correlation with Trails B and Shipley Abstraction; but RCFT Copy scores were more strongly related to these tests, and the SOSS added no significant incremental predictive value beyond the RCFT Copy score. However, SOSS scores did predict RCFT Recall beyond RCFT Copy scores. We conclude that the SOSS has modest reliability and is predictive of RCFT Recall scores, but it is not strongly correlated with other EF measures, and it is only minimally affected by mild TBI.

Effect of Cognitive Training in Fully Immersive Virtual Reality on Visuospatial Function and Frontal-Occipital Functional Connectivity in Predementia: Randomized Controlled Trial.

BackgroundCognitive training can potentially prevent cognitive decline. However, the results of recent studies using semi-immersive virtual reality (VR)-assisted cognitive training are inconsistent.ObjectiveWe aimed to examine the hypothesis that cognitive training using fully immersive VR, which may facilitate visuospatial processes, could improve visuospatial functioning, comprehensive neuropsychological functioning, psychiatric symptoms, and functional connectivity in the visual brain network in predementia.MethodsParticipants over 60 years old with subjective cognitive decline or mild cognitive impairment from a memory clinic were randomly allocated to the VR (n=23) or the control (n=18) group. The VR group participants received multidomain and neuropsychologist-assisted cognitive training in a fully immersive VR environment twice a week for 1 month. The control group participants did not undergo any additional intervention except for their usual therapy such as pharmacotherapy. Participants of both groups were evaluated for cognitive function using face-to-face comprehensive neuropsychological tests, including the Rey-Osterrieth Complex Figure Test (RCFT) copy task; for psychiatric symptoms such as depression, apathy, affect, and quality of life; as well as resting-state functional magnetic resonance imaging (rsfMRI) at baseline and after training. Repeated-measures analysis of variance was used to compare the effect of cognitive training between groups. Seed-to-voxel–based analyses were used to identify the cognitive improvement–related functional connectivity in the visual network of the brain.ResultsAfter VR cognitive training, significant improvement was found in the total score (F1,39=14.69, P=.001) and basic components score of the RCFT copy task (F1,39=9.27, P=.005) compared with those of the control group. The VR group also showed improvements, albeit not significant, in naming ability (F1,39=3.55, P=.07), verbal memory delayed recall (F1,39=3.03, P=.09), and phonemic fluency (F1,39=3.08, P=.09). Improvements in psychiatric symptoms such as apathy (F1,39=7.02, P=.01), affect (F1,39=14.40, P=.001 for positive affect; F1,39=4.23, P=.047 for negative affect), and quality of life (F1,39=4.49, P=.04) were found in the VR group compared to the control group. Improvement in the RCFT copy task was associated with a frontal-occipital functional connectivity increase revealed by rsfMRI in the VR group compared to the control group.ConclusionsFully immersive VR cognitive training had positive effects on the visuospatial function, apathy, affect, quality of life, and increased frontal-occipital functional connectivity in older people in a predementia state. Future trials using VR cognitive training with larger sample sizes and more sophisticated designs over a longer duration may reveal greater improvements in cognition, psychiatric symptoms, and brain functional connectivity.Trial RegistrationClinical Research Information Service KCT0005243; https://tinyurl.com/2a4kfasa

Rey–Osterrieth complex figure normative data for the psychiatric population

Objective: Appropriate normative data are crucial for competent neuropsychological assessment. Although individuals with psychiatric illness often perform more poorly than healthy adults on neuropsychological testing, data that reflect the psychiatric population are often lacking. We present a normative dataset and calculation tools for the Rey–Osterrieth Complex Figure Test (RCFT) derived from the psychiatric inpatient population. Method: A sample of 301 psychiatric inpatients completed the RCFT and the Test of Memory Malingering (TOMM) between 1999 and 2018. Participants were 59.5% male, 82.1% Caucasian, 13.3% black, and 4.6% identified as another racial demographic, largely consistent with recent Substance Abuse and Mental Health Services Administration (2018) data for inpatients in U.S. psychiatric facilities. Scores for RCFT Copy, Short-Delay Free Recall, Long-Delay Free Recall, Total Recognition, and Percent Retained were modeled via multiple regression with age and education as predictors. Base rates were computed for subscores comprising Total Recognition to aid clinical decision making. Results: Age and education served as significant individual predictors for all models except one model predicting percent retained across delay that included only age. Regression equations and regression standard errors were used to produce a score calculator using a commonly available spreadsheet software package. Healthy adult norms under-estimated performance in our sample, underscoring the importance of these normative data. Conclusions: These normative data for the RCFT represent a large cohort of psychiatric inpatients. For clinical practice and research, both the data and the tools provided are likely to be of particular usefulness among individuals with serious mental illness.

Improvements of visuospatial function and frontal‐occipital connectivity after cognitive training using virtual reality in old adults with subjective cognitive decline and mild cognitive impairment

AbstractIntroductionCognitive intervention is believed as a potential therapy to prevent incident dementia. Previous studies using virtual reality (VR)‐assisted cognitive training have shown inconsistent results with minimal effect for patients with mild cognitive impairment (MCI). We investigated the hypothesis that fully immersive VR‐assisted cognitive training would be effective in multidomain cognition, psychological symptoms, and brain connectivity in old adults with subjective cognitive decline (SCD) and MCI.MethodsParticipants were randomly assigned as VR group (n=23; SCD=13 and MCI=10) and control group (n=18; SCD=13 and MCI=5). VR group participants conducted a multi‐domain cognitive training program using fully immersive 3D VR twice a week for a month. Both groups were evaluated of their cognitive function, psychological states, and resting‐state functional magnetic resonance imaging (fMRI) before and after the program.ResultsAfter the VR cognitive training, the VR group showed improvements in the Rey‐Osterrieth complex figure test (RCFT) copy (p&lt;0.001), positive and negative affect schedule‐positive affect (p&lt;0.001), and apathy evaluation scale (p=0.006) compared to control group. Seed‐based correlation analyses on fMRI results showed that improvement in RCFT copy was associated with activation in the frontal‐occipital connectivity in the VR group compared to the control group.ConclusionWe found that the fully immersive 3D VR program had positive effects on visuospatial function, positive affect, apathy, and the frontal‐occipital connectivity in old adults with SCD and MCI. Future trials using VR cognitive training with larger sample sizes, selected participants, and longer duration may find extended improvements in multidomain cognition, psychological aspects, and evidence in the brain activation.

WAIS Information Subtest as an indicator of crystallized cognitive abilities and brain reserve among highly educated older adults: A three-year longitudinal study

The Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) Information Subtest (IS) is known as a neuropsychological “Hold” test that is relatively resistant to decline with aging. We administered neuropsychological tests among highly educated healthy older adults once a year for three subsequent years. Results showed highly stable performances on the IS across years (Mean Z score: T0 = 1.39, SD = 0.60; T1 = 1.37, SD = 0.77; T2 = 1.50, SD = 0.66; T3 = 1.48, SD = 0.66), that were significantly higher than zero (T0: t = 12.08; T1: t = 9.29; T2: t = 11.71; T3: t = 11.68; for all, p < 0.0001). In contrast, other neuropsychological tests showed differences in performance across time; some performances significantly declined (Rey Osterrieth Complex Figure test-copy, Rey-Auditory Verbal Learning Test, and Montreal Cognitive Assessment test [MoCA]), whereas others were improved, possibly due to practice effects (Rey Osterrieth Complex Figure test- delayed, Rey-Auditory Verbal Learning Test- delayed, and Trail Making Test- part A). Correlation with whole brain volumetric analysis revealed a positive correlation between gray matter volumes and IS scores (r = 0.46, p < 0.05) even when controlling for age and education (partial correlations: r = 0.43; r = 0.45, for both p < 0.05). No significant correlations were found between gray matter and other test scores. Therefore, the WAIS-III Information subtest appears to be an adequate neuropsychological measurement of crystallized ability in highly educated older adults and may be considered as a proxy measure of brain reserve.

Exploring the relation between learning style and cognitive impairment in patients with acquired brain injury

The way a patient prefers to approach or choose a learning situation represents the patient's learning style. The objective of this chart review study was to explore the relation between learning style and cognitive impairment in patients with acquired brain injury (ABI). We used data from files of 92 adult patients with ABI referred to inpatient rehabilitation, who completed the Adapted Learning Style Inventory (A-LSI) and at least one of the following neuropsychological tests: Trail Making Test, Rey Auditory Verbal Learning Test, WAIS-III Digit Span, Rey-Osterrieth Complex Figure Test–Copy, Stroop Color-Word Test, or the Brixton Spatial Anticipation Test. The A-LSI yielded the following distribution of learning styles: 4 doers, 48 observers, 2 deciders and 38 thinkers. No significant correlation coefficients were found between the neuropsychological tests and the A-LSI. Furthermore, Chi-square tests revealed no significant associations between learning style (observer, thinker) and cognitive impairment. The results of this exploratory study suggest that learning style and cognitive impairment are independent in patients with ABI.

Influence of specific obsessive-compulsive symptom dimensions on strategic planning in patients with obsessive-compulsive disorder

This study investigates obsessive-compulsive disorder patients in terms of strategic planning and its association with specific obsessive-compulsive symptom dimensions. We evaluated 32 obsessive-compulsive disorder patients. Strategic planning was assessed by the Rey-Osterrieth Complex Figure Test, and the obsessive-compulsive dimensions were assessed by the Dimensional Yale-Brown Obsessive-Compulsive Scale. In the statistical analyses, the level of significance was set at 5%. We employed linear regression, including age, intelligence quotient, number of comorbidities, the Yale-Brown Obsessive-Compulsive Scale score, and the Dimensional Yale-Brown Obsessive-Compulsive Scale. The Dimensional Yale-Brown Obsessive-Compulsive Scale "worst-ever" score correlated significantly with the planning score on the copy portion of the Rey-Osterrieth Complex Figure Test (r = 0.4, p = 0.04) and was the only variable to show a significant association after linear regression (β = 0.55, t = 2.1, p = 0.04). Compulsive hoarding correlated positively with strategic planning (r = 0.44, p = 0.03). None of the remaining symptom dimensions presented any significant correlations with strategic planning. We found the severity of obsessive-compulsive symptoms to be associated with strategic planning. In addition, there was a significant positive association between the planning score on the copy portion of the Rey-Osterrieth Complex Figure Test copy score and the hoarding dimension score on the Dimensional Yale-Brown Obsessive-Compulsive Scale. Our results underscore the idea that obsessive-compulsive disorder is a heterogeneous disorder and suggest that the hoarding dimension has a specific neuropsychological profile. Therefore, it is important to assess the peculiarities of each obsessive-compulsive symptom dimension.

Neuropsychological Outcomes of Older Breast Cancer Survivors: Cognitive Features Ten or More Years After Chemotherapy

Neuropsychological Outcomes of Older Breast Cancer Survivors: Cognitive Features Ten or More Years After Chemotherapy

Neuropsychological Outcomes of Older Breast Cancer Survivors: Cognitive Features Ten or More Years After Chemotherapy

The authors examined the long-term cognitive implications of cancer treatment among breast cancer survivors over 65 years old who received treatment during midlife. Thirty women survivors were matched with 30 noncancer, healthy older adults in terms of age, education, and IQ. The cancer survivors scored significantly lower in the cognitive domains of executive functioning, working memory, and divided attention, reflecting potential dysfunction in frontal-subcortical brain regions. Our findings suggest that among breast cancer survivors who remain disease-free for more than a decade, the previous cancer treatment may further augment cognitive dysfunction associated with age-related brain changes.

Association between EEG alpha power and visuospatial function in obsessive-compulsive disorder.

The purpose of the present paper was to determine if frontal activity, measured as electroencephalogram alpha power, correlates with visuospatial functions in obsessive-compulsive disorder (OCD). Electroencephalography and the Rey-Osterrieth Complex Figure Test (RCFT) were performed on 23 patients meeting the Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) OCD criteria. After quantitatively analyzing EEG recordings taken over the frontal, temporal, parietal and occipital regions (F1, F2, T3, T4, P3, P4, O1 and O2), the log transformed absolute power values of the alpha frequencies of the regions were regressed with each RCFT index (copy, immediate recall and delayed recall score). On the frontal region (F1, F2), the RCFT copy score was found to be correlated with the alpha power with regression coefficients that had different directions according to hemisphere (F1, 5.62; F2, -5.26). The result that visuo-constructional ability represented by the RCFT copy score correlated with frontal activation as measured by decreased alpha power, supports the opinion that visuospatial dysfunction in OCD is not in the visuospatial memory per se but rather that it is mediated by executive function deficit. The opposite correlation directions indicate that greater left frontal activation correlates with a poorer RCFT copy score and that greater right frontal activation correlates with a better copy score. These relationships provide indirect evidence of the possibility that the main pathology of OCD is located in the left hyperfrontality and that the right hyperfrontality of OCD occurs by a compensatory mechanism.
