Neuropsychiatric symptoms and cerebrovascular risk in non-demented elders: cross-sectional study using the mild behavioural impairment checklist (MBI-C). Psychogeriatrics 2022; 22:55-66.

Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) may represent early clinical manifestations of evolving brain diseases. Studies underpin the occurrence of NPS in the context of mild cognitive impairment (MCI) and prodromal Alzheimer's disease, where symptoms referred to as 'mild behavioural impairment' (MBI) have been shown to predict conversion to dementia and to hasten cognitive/functional decline. However, the association between NPS and cerebrovascular risk factors has been poorly investigated, despite the high prevalence of the latter among individuals with MCI. The aim of the present study was to investigate the association between MBI and cerebrovascular risk in a clinical sample of non-demented elders. METHODS Sixty-five MCI and 15 cognitively unimpaired older adults were cross-sectionally assessed with the Mild Behavioural Impairment Checklist (MBI-C), using the cut-off score > 6.5 to define positive screening. Participants were submitted to the Hachinski Ischaemic Score (HIS) to account for cerebrovascular symptoms, vascular risk, and related comorbidities. Neuroimaging scans (magnetic resonance imaging and/or 18F-fluorodeoxyglucose-positron emission tomography) and apolipoprotein E genotype were obtained. RESULTS Positive associations were found between total MBI-C scores and increasing number of comorbidities present (0-2 comorbidities), but not with three comorbidities. Two domains of the MBI-C-impulse dyscontrol and social inappropriateness-followed the same trend of the MBI-C total score, with higher scores with the increasing numbers of comorbidities. No significant associations were found between MBI symptoms and HIS or cerebrovascular burden in neuroimaging assessment. CONCLUSION We found weak associations between MBI-C total score and the presence of comorbidities with cerebrovascular risk, but not with structural or functional neuroimaging abnormalities or HIS. This finding may represent that the presence of comorbidities adds limited risk to the occurrence of MBI in this sample of non-demented elders.

Abstract
BACKGROUND Individuals with the behavioral variant of frontotemporal dementia (bvFTD) exhibit various levels of abulia, disinhibition, impaired judgment, and decline in executive function. Empirical evidence has shown that individuals with bvFTD also often exhibit difficulty using honorific speech, which expresses respect to another party or addressee. OBJECTIVE To analyze differences in the ability to use honorific speech among individuals with bvFTD, individuals with dementia of the Alzheimer type (AD dementia), and individuals with normal cognition (NC). METHOD A total of 53 native Korean speakers (13 bvFTD, 20 AD dementia, and 20 NC) completed an experimental honorific speech task (HST) that involved both expressive and receptive tasks. We analyzed the number of correct responses and error patterns separately for an expressive task and for a receptive task. RESULTS The bvFTD group had significantly fewer correct responses on the HST compared with the AD dementia and NC groups. The bvFTD group exhibited more misjudgment errors in identifying nonhonorific speech as honorific speech in the expressive task, and significantly longer response times in the receptive task, than the AD dementia and NC groups. Significant associations were identified between HST scores and cortical atrophy in the temporal and frontotemporal lobes. CONCLUSION A decline in the ability to use honorific speech may be a diagnosable behavioral and psychiatric symptom for bvFTD in Korean-speaking individuals. This decline in individuals with bvFTD could be attributed to multiple factors, including social manners (politeness) and impaired social language use ability (pragmatics).

Abstract
Frontotemporal lobar dementia (FTLD) is a clinically and pathologically complex disease. Advances in neuroimaging techniques have provided a specialized set of tools to investigate underlying pathophysiology and identify clinical biomarkers that aid in diagnosis, prognostication, monitoring, and identification of appropriate endpoints in clinical trials. In this chapter, we review data discussing the utility of neuroimaging biomarkers in sporadic FTLD, with an emphasis on current and future clinical applications. Among those modalities readily utilized in clinical settings, T1-weighted structural magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) are best supported in differential diagnosis and as targets for clinical trial endpoints. However, a number of nonclinical neuroimaging modalities, including diffusion tensor imaging and resting-state functional connectivity MRI, show promise as biomarkers to predict progression and as clinical trial endpoints. Other neuroimaging modalities, including amyloid PET, Tau PET, and arterial spin labeling MRI, are also discussed, though more work is required to establish their utility in FTLD in clinical settings.

Abstract
After decades of research, large-scale clinical trials in patients diagnosed with frontotemporal lobar degeneration (FTLD) are now underway across multiple centres worldwide. As such, refining the determinants of survival in FTLD represents a timely and important challenge. Specifically, disease outcome measures need greater clarity of definition to enable accurate tracking of therapeutic interventions in both clinical and research settings. Multiple factors potentially determine survival, including the clinical phenotype at presentation; radiological patterns of atrophy including markers on both structural and functional imaging; metabolic factors including eating behaviour and lipid metabolism; biomarkers including both serum and cerebrospinal fluid markers of underlying pathology; as well as genetic factors, including both dominantly inherited genes, but also genetic modifiers. The present review synthesises the effect of these factors on disease survival across the syndromes of frontotemporal dementia, with comparison to amyotrophic lateral sclerosis, progressive supranuclear palsy and corticobasal syndrome. A pathway is presented that outlines the utility of these varied survival factors for future clinical trials and drug development. Given the complexity of the FTLD spectrum, it seems unlikely that any single factor may predict overall survival in individual patients, further suggesting that a precision medicine approach will need to be developed in predicting disease survival in FTLD, to enhance drug target development and future clinical trial methodologies.

Abstract
Frontotemporal dementia (FTD) includes a group of neurocognitive syndromes, clinically characterized by altered behaviors, impairment of language proficiency, and altered executive functioning. FTD is one of the most frequently observed forms of dementia in the elderly population and the most common in presenile age. As for other subtypes of dementia, FTD incidence is constantly on the rise due to the steadily increasing age of the population, and its recognition is now becoming a determinant for clinicians. FTD and psychiatric disorders can overlap in terms of clinical presentations by sharing a common genetic predisposition and neuropathological mechanism in some cases. Nonetheless, this association is often unclear and underestimated. Since its first reports, research into FTD has constantly grown, with the identification of recent findings related to its neuropathology, genetic, clinical, and therapeutic issues. Literature is thriving on this topic, with numerous research articles published in recent years. In the present review, we aimed to provide an updated description of the clinical manifestations that link and potentially confound the diagnosis of FTD and psychiatric disorders in order to improve their differential diagnosis and early detection. In particular, we systematically reviewed the literature, considering articles specifically focused on the behavioral variant FTD, published after 2015 on the PubMed database.

Abstract
BACKGROUND AND PURPOSE Predicting the course of behavioural variant frontotemporal dementia (bvFTD) remains a major clinical challenge. This study aimed to identify factors that predict survival and clinical progression in bvFTD. METHODS Consecutive patients with clinically probable bvFTD were prospectively followed up over an 8-year period. Baseline neuropsychological variables, presence of a known pathogenic frontotemporal dementia gene mutation and a systematic visual magnetic resonance imaging assessment at baseline were examined as candidate predictors using multivariate modelling. RESULTS After screening 121 cases, the study cohort consisted of 75 patients with probable bvFTD, with a mean age of 60.8 ± 8.5 years, followed up for a mean duration of 7.2 ± 3.5 years from symptom onset. Median survival time from disease onset was 10.8 years and median survival, prior to transition to nursing home, was 8.9 years. A total of 25 of the 75 patients died during the study follow-up period. Survival without dependence was predicted by shorter disease duration at presentation (hazard ratio, 0.49, P = 0.001), greater atrophy in the anterior cingulate cortex (hazard ratio, 1.75, P = 0.047), older age (hazard ratio, 1.07, P = 0.026) and a higher burden of behavioural symptoms (hazard ratio, 1.04, P = 0.015). In terms of disease progression, presence of a known pathogenic frontotemporal dementia mutation (β = 0.46, P < 0.001) was the strongest predictor of progression. Deficits in letter fluency (β = -0.43, P = 0.017) and greater atrophy in the motor cortex (β = 0.51, P = 0.03) were also associated with faster progression. CONCLUSIONS This study provides novel clinical predictors of survival and progression in bvFTD. Our findings are likely to have an impact on prognostication and care planning in this difficult disease.
