Abstract
Most people with dementia experience neuropsychiatric symptoms (NPS), including anxiety, depression or disinhibition. There is growing interest in the relationship between NPS and cognitive impairment, but data is still limited. This study aimed to investigate the specific associations between NPS and cognition in people with dementia. MEDLINE, EMBASE and PsycINFO were searched for published, peer-reviewed studies of associations between at least one NPS and one cognitive ability in people with dementia. The quality of the studies was assessed with the NIH National Heart, Lung and Blood Institute's quality assessment tools. A meta-analysis was conducted using Robumeta package for R. Ninety studies were included. We found significant associations between NPS, global cognition and cognitive domains, e.g. apathy was associated with global cognitive and memory impairment; dysphoria was associated with worse attention; delusions with executive dysfunction. Increased NPS in people with dementia are associated with worse cognitive performance. There were few studies looking at associations between some neuropsychiatric clusters and cognitive abilities, and there was little research on causal relationships. Our review was limited by the inclusion of studies that reported associations in specific formats, and most included people with a diagnosis of Alzheimer's disease (AD). However, given the large number of studies, this is unlikely to have biased results. More research is needed that includes diverse people with different dementia syndromes. Registration: PROSPERO 2020 CRD42020165565.

Abstract
OBJECTIVE The potential impact of sex on cognitive performance in normal aging and participants with Alzheimer's disease (AD) has been outlined previously. Nevertheless, differences in neuropsychiatric symptoms (NPS) have been also outlined. We aimed to study a potential association between NPS and cognitive performances according to sex, in older individuals with and without cognitive impairment. METHODS Demographic, neuropsychiatric and neuropsychological data from the ADNI and NACC databases were merged into a dataset of 506 participants with healthy cognitive performance, 467 patients with mild cognitive impairment, and 238 patients with AD. Cognitive performance in each group was evaluated according to sex and the presence of NPS. RESULTS Based on sex, cognitive performance differed according to clinical stage: in the healthy controls and AD groups, women had better fluency performance, while in the mild cognitive impairment group, women had better working memory and men better oral naming. Regardless of sex, depression showed a negative effect on processing speed in AD. Finally, there was an interaction between sex and NPS in mild cognitive impairment, where women with apathy had better working memory performance, and in AD, women with depression had better fluency performance. The opposite pattern being was observed in men, where men with depression have worse focused attention. CONCLUSION Cognitive performance is influenced by sex, yet this influence has different manifestations at normal cognition, MCI or AD. Furthermore, apathy and depression seem to influence differently women and men at different types of cognitive decline.

Abstract
Background: Hallucinations in Alzheimer’s disease (AD) have been linked to more severe cognitive and functional decline. However, research on visual hallucinations (VH), the most common type of hallucinations in AD, is limited. Objective: To investigate the cognitive and cerebral macrostructural and metabolic features associated with VH in AD. Methods: Twenty-four AD patients with VH, 24 with no VH (NVH), and 24 cognitively normal (CN) matched controls were selected from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. Differences in regional gray matter (GM) volumes and cognitive performance were investigated with whole brain voxel-based morphometry analyses of MRI structural brain scans, and analyses of neuropsychological tests. Glucose metabolic changes were explored in a subsample of patients who had FDG-PET scans available. Results: More severe visuoconstructive and attentional deficits were found in AD VH compared with NVH. GM atrophy and hypometabolism were detected in occipital and temporal areas in VH patients in comparison with CN. On the other hand, NVH patients had atrophy and hypometabolism mainly in temporal areas. No differences in GM volume and glucose metabolism were found in the direct comparison between AD VH and NVH. Conclusion: In addition to the pattern of brain abnormalities typical of AD, occipital alterations were observed in patients with VH compared with CN. More severe visuoconstructive and attentional deficits were found in AD VH when directly compared with NVH, and might contribute to the emergence of VH in AD.

Abstract
INTRODUCTION Psychosis is one of the incapacitating nonmotor symptoms of Parkinson's disease (PD). Although several risk factors that include older age, rapid eye movement sleep behavior disorder, depression, and cognitive dysfunction have been identified, the exact neural correlates remain elusive. As cognitive impairment has a close association with psychosis in PD, it is useful to know the spectrum of cognitive impairment in PD patients with psychosis (PD-P). METHODS This cross-sectional study compared various cognitive parameters of PD-P (visual/minor hallucinations) and PD patients with no psychosis (PD-NP). A neuropsychological battery encapsulating several cognitive domains (executive, visuospatial, learning, and memory) was used for the cognitive assessment of 37 PD-P and 51 PD-NP patients who were matched for age, gender, education, and disease duration. RESULTS The two groups were comparable in terms of disease severity and stage. Although the groups had a comparable mean score on Montreal cognitive assessment, the PD-P group performed poorly in tests focused on executive function (color trail test, forward digit span), verbal learning and memory (Rey auditory and verbal learning test), and visuospatial functions (complex figure test, corsi block tapping test). Those with complex visual hallucinations performed poorly in the color trial test (part A) compared to those with minor hallucinations. CONCLUSION Psychosis is associated with a multidomain cognitive dysfunction in PD. All PD patients should undergo detailed cognitive assessment as cognitive dysfunction may be a marker of psychosis in the future. Additional longitudinal studies are warranted to obtain detailed insights into this issue.

Abstract
Individuals with neurocognitive disorders (NCD) frequently experience psychotic symptoms, such as delusions. Delusions can contribute to other behavior problems, create dangers for patients and caregivers, and contribute to inpatient hospitalization of individuals with NCD. The current study aimed to identify cognitive symptoms associated with the presence of delusions and to differentiate delusion types based on cognitive profiles among hospitalized older adults with NCD. A review of electronic medical records of hospitalized older adults from an inpatient geriatric psychiatry setting yielded 185 patients with a diagnosis of mild or major NCD who had a neuropsychological evaluation during their admission and whose documentation described a clear delusion. We identified a comparison group of 185 patients without delusions well matched for age, education, and sex, and similar in global cognitive status. Exclusion criteria included delirium and history of a psychotic disorder. We first compared the groups' performances on a dementia battery. Then, cognitive performances of subgroups with specific delusion types (harm, theft, jealousy, and misidentification) were each compared to the remainder of the delusion-positive group. Exploratory analyses revealed that the delusion-positive group had a greater rate of discontinuation on Trails B and performed worse than the delusion-negative group on Trails A, Behavioral Dyscontrol Scale, Semantic Fluency, and Hopkins Verbal Learning Test-Revised (HVLT-R) initial registration. Theft delusions were associated with worse performance on HVLT-R recognition, misidentification delusions were associated with worse performance on Trails B, and harm delusions were associated with worse performance on a verbal generativity test. The presence of delusions in hospitalized older adults with NCD was associated with worse performance on several cognitive tasks with many being suggestive of associated with frontal-subcortical network integrity. Delusions of theft may be a consequence of reduced integrity of medial temporal lobe memory system.

Abstract
OBJECTIVE This study was aimed at evaluating the association between cognitive functioning and the occurrence of behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer's disease (AD). METHODS/DESIGN The population is derived from the PACO cohort, including 237 patients with prodromal or mild AD. A neuropsychological tests battery exploring verbal and visual memory, language, attention, and executive functions was performed at baseline. BPSD were assessed at 6-, 12-, and 18-month follow-up with neuropsychiatric inventory (NPI). RESULTS Lower baseline performance on Stroop test interference score was associated with higher subsequent overall NPI scores (P = .006), subscores of anxiety/depression (P = .03), and apathy inventory (P = .01). Conversely, other executive functions, verbal or visual memory, and language performances were not associated with a higher risk of BPSD. CONCLUSION Our results suggest that poorer inhibition performance would be associated with a higher risk of 18-month BPSD occurrence, including anxiety, depression, and apathy. A better knowledge of the predictive factors of the BPSDs would make it possible to better identify the patients at risk, to propose preventive strategies and an earlier adapted care.

Abstract
Alzheimer's disease (AD) is the most common cause of dementia and the number of elderly patients suffering from AD has been steadily increasing. Despite worldwide efforts to cope with this disease, little progress has been achieved with regard to identification of effective therapeutics. Thus, active research focusing on identification of new therapeutic targets of AD is ongoing. Among the new targets, post-translational modifications which modify the properties of mature proteins have gained attention. O-GlcNAcylation, a type of PTM that attaches O-linked β-N-acetylglucosamine (O-GlcNAc) to a protein, is being sought as a new target to treat AD pathologies. O-GlcNAcylation has been known to modify the two important components of AD pathological hallmarks, amyloid precursor protein, and tau protein. In addition, elevating O-GlcNAcylation levels in AD animal models has been shown to be effective in alleviating AD-associated pathology. Although studies investigating the precise mechanism of reversal of AD pathologies by targeting O-GlcNAcylation are not yet complete, it is clearly important to examine O-GlcNAcylation regulation as a target of AD therapeutics. This review highlights the mechanisms of O-GlcNAcylation and its role as a potential therapeutic target under physiological and pathological AD conditions.

Abstract
Early Alzheimer's disease (AD) and depression share many symptoms, but the underlying mechanisms are not clear. Therefore, characterizing the shared and different biological changes between the two disorders will be helpful in making an early diagnosis and planning treatment. In the present study, 8-week-old APPSwe/PS1dE9 transgenic mice received chronic mild stress (CMS) for 8 weeks followed by a series of behavioral, biochemical and pathological analyses. APPSwe/PS1dE9 mice showed depressive- and anxiety-like behaviors, and reduced sociability, accompanied by high levels of soluble beta-amyloid, glial activation, neuroinflammation and brain derived neurotrophic factor signaling disturbance in the hippocampus. Notably, APPSwe/PS1dE9 mice exposure to CMS partially aggravated anxiety-like states rather than depressive-like responses and sociability deficits, with further elevated hippocampal interleukin-6 and tumor necrosis factor-α levels. These results demonstrated that young adult APPSwe/PS1dE9 have depressive- and anxiety-like phenotypes that were resistant to CMS compared to wild-type mice. This finding may help to understand the pathogenic mechanism of psychiatric symptoms associated with early AD.

Abstract
BACKGROUND The pattern of neuropsychiatric features of patients with neurosyphilis and the impact of the severity of cognitive impairment on neuropsychiatric syndromes are unknown. OBJECTIVE We aim to assess the neuropsychiatric features of patients with neurosyphilis, and compare the impact of the severity of cognitive impairment on the neuropsychiatric syndromes between neurosyphilis and Alzheimer disease (AD). METHODS Neuropsychiatric symptoms and the degree of cognitive impairment were assessed in a case-control study of 91 neurosyphilis, 162 AD, 157 mild cognitive impairment, and 139 normal controls by the Neuropsychiatric Inventory (NPI) scale and Clinical Dementia Rating scale, respectively. Factor analysis was performed on the 12 NPI items. RESULTS Factor analysis showed that patients with neurosyphilis showed more severe neuropsychiatric syndromes at the dementia stage than those neurosyphilis patients at the mild cognitive impairment stage, while neuropsychiatric manifestations were equally common among the different stages of dementia (all p < 0.05). Frontal lobe syndrome was more severe in patients with neurosyphilis than in patients with AD from the early mild cognitive impairment stage to the moderate dementia stage (all p < 0.01). CONCLUSIONS Patients with neurosyphilis show different patterns of neuropsychiatric syndromes at the mild cognitive impairment and dementia stages, and differ from patients with AD.

Abstract
BACKGROUND The aim of this study was to investigate the frequency and severity of neuropsychiatric symptoms (NPS) in patients with early onset Alzheimer's disease (EAOD) and late onset AD (LOAD). METHODS Patients were selected from a specialized memory outpatient clinic. The Mini-Mental State Examination, the Neuropsychiatric Inventory (NPI), and the Global Deterioration Scale results were analyzed. RESULTS By comparing EOAD (n = 35) and LOAD (n = 35) patients, no significant differences were found in clinical or demographic variables, matched for sex, education, and disease severity. There were no differences between groups in total NPI frequency or severity scores. The most common NPS were irritability, apathy, anxiety, and depression. We found an association of NPI scores with disease severity and duration, which was more specific in patients with LOAD and was also associated with the presence of delusions and hallucinations. CONCLUSION Despite subtle differences, NPS is considered important in the assessment of patients with AD, regardless of the age of onset.

Abstract
BACKGROUND Psychosis is a common phenomenon in Alzheimer's disease (AD). The APOE ε4 allele is the strongest genetic risk factor for the development of AD, but its association with psychosis remains unclear. OBJECTIVE We investigated the associations between psychosis, subdivided into delusions and hallucinations, as well as APOE ε4 allele on cognitive and functional outcomes. Secondarily, we investigated the associations between APOE ε4, Lewy bodies, and psychosis. METHODS Data from the National Alzheimer's Coordinating Center (NACC) were used. Nine hundred patients with a confirmed diagnosis of AD based on the NIA-AA Reagan were included in the analysis. Global cognition was assessed using the Mini-Mental State Exam (MMSE) and functional status was assessed using the Functional Activities Questionnaire (FAQ). Psychosis status was determined using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Factorial design was used to assess the effects of psychosis and APOE ε4, as well as their interaction. RESULTS Psychosis and the presence of APOE ε4 were both associated with lower MMSE scores, while only psychosis was associated with higher FAQ scores. Furthermore, patients with hallucinations had lower MMSE and higher FAQ scores than patients with only delusions. There was a significant interaction effect between psychosis and APOE ε4 on MMSE scores, with APOE ε4 negatively affecting patients with hallucinations-only psychosis. APOE ε4 was positively associated with the presence of Lewy body pathology, and both were found to be more prevalent in psychotic patients, with a stronger association with hallucinations. CONCLUSION Psychosis in AD was associated with greater cognitive and functional impairments. Patients with hallucinations-with or without delusions-conferred even greater deficits compared to patients with only delusions. The APOE ε4 allele was associated with worse cognition, especially for patients with hallucination-only psychosis. APOE ε4 may mediate cognitive impairment in the hallucinations phenotype through the development of Lewy bodies. Our findings support that subtypes of psychosis should be evaluated separately.

Abstract
BACKGROUND Behavioral and psychological symptoms of dementia (BPSD) are prevalent in people with neurodegenerative diseases. PURPOSE In this scoping review the Kales, Gitlin and Lykestos framework is used to answer the question: What high quality evidence exists for the patient, caregiver and environmental determinants of five specific BPSD: aggression, agitation, apathy, depression and psychosis? METHOD An a priori review protocol was developed; 692 of 6013 articles retrieved in the search were deemed eligible for review. Gough's Weight of Evidence Framework and the Cochrane Collaboration's tool for assessing risk of bias were used. The findings from 56 high quality/low bias articles are summarized. DISCUSSION Each symptom had its own set of determinants, but many were common across several symptoms: neurodegeneration, type of dementia, severity of cognitive impairments, and declining functional abilities, and to a lesser extent, caregiver burden and communication. CONCLUSION Research and policy implications are relevant to the National Plan to Address Alzheimer's Disease.

Abstract
Psychosis is one of the debilitating non-motor symptoms (NMS) of Parkinson's disease (PD). Cognitive impairment is considered to be a risk factor for emergence of psychosis in PD. Early detection of relevant cognitive impairment may serve as a predictor for development of psychosis, with implications for prevention and early intervention. However, the exact pattern of cognitive impairment associated with psychosis is not clear. In this article, we aim to critically review the literature on case-control studies in PD patients with and without psychosis in order to understand the pattern of cognitive impairment in those with psychosis. Majority of studies conducted till date have focused on executive and visuospatial functions. Despite some inconsistencies, most of the studies found significant impairment in these domains in PD patients with psychosis compared to those without psychosis. Studies assessing for other cognitive functions such as attention, language and memory in PD patients have also found worse performance in those with psychosis. Although there is enough evidence to suggest that PD patients with psychosis have poor cognitive functioning, it is unclear if these deficits are generalized or specific. The available evidence, which is primarily in the form of cross-sectional studies assessing for specific cognitive deficits, is not adequate to indicate a clear demarcating pattern of cognitive deficits, which differentiates PD patients with and without psychosis. Longitudinal studies with extensive cognitive assessment are warranted.

Differences of Behavioral and Psychological Symptoms of Dementia in Disease Severity in Four Major Dementias. PLoS One 2016; 11:e0161092. [PMID: 27536962 PMCID: PMC4990196 DOI: 10.1371/journal.pone.0161092] [Citation(s) in RCA: 82] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2016] [Accepted: 07/31/2016] [Indexed: 11/19/2022] Open
Abstract
Background/Aims Behavioral and psychological symptoms of dementia (BPSDs) negatively impact the prognosis of dementia patients and increase caregiver distress. The aims of this study were to clarify the differences of trajectories of 12 kinds of BPSDs by disease severity in four major dementias and to develop charts showing the frequency, severity, and associated caregiver distress (ACD) of BPSDs using the data of a Japan multicenter study (J-BIRD). Methods We gathered Neuropsychiatric Inventory (NPI) data of patients with Alzheimer’s disease (AD; n = 1091), dementia with Lewy bodies (DLB; n = 249), vascular dementia (VaD; n = 156), and frontotemporal lobar degeneration (FTLD; n = 102) collected during a 5-year period up to July 31, 2013 in seven centers for dementia in Japan. The NPI composite scores (frequency × severity) of 12 kinds of items were analyzed using a principal component analysis (PCA) in each dementia. The factor scores of the PCA were compared in each dementia by disease severity, which was determined with Clinical Dementia Rating (CDR). Results Significant increases with higher CDR scores were observed in 1) two of the three factor scores which were loaded for all items except euphoria in AD, 2) two of the four factor scores for apathy, aberrant motor behavior (AMB), sleep disturbances, agitation, irritability, disinhibition, and euphoria in DLB, and 3) one of the four factor scores for apathy, depression, anxiety, and sleep disturbances in VaD. However, no increases were observed in any of the five factor scores in FTLD. Conclusions As dementia progresses, several BPSDs become more severe, including 1) apathy and sleep disturbances in AD, DLB, and VaD, 2) all of the BPSDs except euphoria in AD, 3) AMB, agitation, irritability, disinhibition, and euphoria in DLB, and 4) depression and anxiety in VaD. Trajectories of BPSDs in FTLD were unclear.
