RESUMEN

BACKGROUND: This study aimed at (1) delivering generalizable estimates of the prevalence of frontotemporal-spectrum disorders (FTSDs) in non-demented ALS patients and (2) exploring their motor-functional correlates. METHODS: N = 808 ALS patients without FTD were assessed for motor-functional outcomes-i.e., disease duration, severity (ALSFRS-R), progression rate (ΔFS), and stage (King's and Milano-Torino-MiToS-systems)-cognition-via the cognitive section of the Edinburgh Cognitive and Behavioural ALS Screen (ECAS)-and behaviour-via the ECAS-Carer Interview. Neuropsychological phenotypes were retrieved via Strong's revised criteria-i.e., ALS cognitively and behaviourally normal (ALScbn) or cognitively and/or behaviourally impaired (ALSci/bi/cbi). RESULTS: Defective ECAS-Total performances were detected in ~ 29% of patients, with the ECAS-Executive being failed by the highest number of patients (~ 30%), followed by the ECAS-Language, -Fluency, and -Memory (~ 15-17%) and -Visuospatial (~ %8). Apathy was the most frequent behavioural change (~ 28%), followed by loss of sympathy/empathy (~ 13%); remaining symptoms were reported in < 4% of patients. The distribution of Strong's classifications was as follows: ALScbn: 46.7%; ALSci/bi/cbi: 22.9%/20.0%/10.4%. Multinomial regressions on Strong's classifications revealed that lower ALSFRS-R scores were associated with a higher probability of ALSbi and ALScbi classifications (p ≤ .008). Higher King's and MiToS stages were associated with a higher probability of ALSbi classification (p ≤ .031). CONCLUSIONS: FTSDs affect ~ 50% of non-demented ALS patients, with cognitive deficits being as frequent as behavioural changes. A higher degree of motor-functional involvement is associated with worse behavioural outcomes-with this link being weaker for cognitive deficits.

RESUMEN

Primary progressive aphasia (PPA) is a neurodegenerative brain disorder characterized by declining language ability. It is a rare, often young-onset dementia with a devastating impact on the work and personal activities of those affected. At present there is no cure or disease-modifying therapy for PPA nor any way to arrest or slow the underlying progressive brain degeneration. Throughout the course of the condition any treatment must therefore be palliative-designed to manage symptoms and improve the quality of life of the affected person. The majority of those affected receive little or no follow-up care after diagnosis, particularly in the early stage of the disease. There is very little information in the medical literature about person-centered care designed to improve the quality of life of people with PPA written from the perspective of those living with this condition. I received an early and accurate clinical diagnosis of the nonfluent/agrammatic variant of PPA, supported by imaging. I am fortunate to have benefited from exemplary individualized care from a multidisciplinary medical team from the onset of my difficulties with language. In this paper, I discuss my lived experience of all aspects of this personalized and person-centered care, describing how it was founded on shared decision-making and a holistic, dementia-inclusive approach encompassing the physical, mental, emotional, psychosocial and spiritual dimensions of living with an incurable neurodegenerative disease.

RESUMEN

INTRODUCTION: It has been recently acknowledged that deficits in experiencing and processing one's own emotions, also termed alexithymia, may possibly feature the frontotemporal-spectrum disorders. This study aims to determine whether alexithymia could be included within the frontotemporal syndromes of amyotrophic lateral sclerosis (ALS). METHODS: Alexithymic traits were estimated in a cohort of 68 non-demented ALS patients with the 20-item Toronto Alexithymia Scale (TAS-20). Patients were assessed for the identification of motor-phenotypes and frontotemporal syndromes based on current classification criteria. Spearman's coefficients explored the correlates of TAS-20 measures with motor-functional profiles, global cognitive, social-cognitive (emotion recognition and empathy) and behavioral status. RESULTS: Abnormal TAS-20 scores were found in 13% of patients, and their distribution did not vary within motor and frontotemporal phenotypes. Significant associations were detected between TAS-20 and executive (p ≤ .011), memory (p = .006), state-anxiety (p ≤ .013) and depression measures (p ≤ .010). By contrast, TAS-20 scores were unrelated to social-cognitive performances, dysexecutive and apathetic profiles. Disease duration was the only motor-functional feature being related to the TAS-20 (p ≤ .008). CONCLUSIONS: Alexithymia of potential clinical relevance occur in a minority of ALS patients, and its neuropsychological correlates mostly resemble those featuring the general population. Hence, it is unlikely that alexithymia is a specific feature of frontotemporal-spectrum characterizing ALS, rather it could be an expression of psychogenic factors as a reaction to the disease.

RESUMEN

BACKGROUND: This study aimed at preliminarily assessing, in a cohort of non-demented amyotrophic lateral sclerosis (ALS) patients, the ecological validity, and more specifically the veridicality, of the Edinburgh Cognitive and Behavioural ALS Screen (ECAS) and the ALS Cognitive Behavioral Screen (ALS-CBS™), by relating their scores to caregiver-report ratings of cognitive changes. METHODS: N = 147 patient-caregiver dyads were recruited. Patients were administered the ECAS and ALS-CBS™, whilst caregiver the Caregiver Behavioral Questionnaire (CBQ) and Beaumont Behavioural Inventory (BBI). An Ecological Cognitive Functioning Index (ECFI) was derived from those items of the CBQ and BBI that tap on executive and language changes. Ecological validity was assessed via both correlational and predictive analyses net of caregiver-rated behavioural changes (as assessed by the ECAS-Carer Interview). RESULTS: The ECFI was associated with the total scores on both the ECAS (p = .014) and ALS-CBS™ (p = .017). When looking at ECAS and ALS-CBS™ subscales, those assessing verbal fluency were selectively associated with the ECFI. The ECFI was higher in patients performing defectively on the ECAS (p = .004) and on the ALS-CBS™ (p = .027). DISCUSSION: This study suggests that both the ECAS and the ALS-CBS™ represent a valid estimate of non-demented ALS patients' cognitive status in the real world, also highlighting the clinical relevance of cognitive changes reported by caregivers.

RESUMEN

INTRODUCTION: The present study aimed at testing the longitudinal feasibility of the Montreal Cognitive Assessment (MoCA) in an Italian cohort of non-demented amyotrophic lateral sclerosis (ALS) patients. METHODS: N = 39 non-demented ALS patients were followed-up at a 5-to-10-month interval (M = 6.8; SD = 1.4) with the MoCA and the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Practice effects, test-retest reliability, and predictive validity (against follow-up ECAS scores) were assessed. Reliable change indices (RCIs) were derived via a regression-based approach by accounting for retest interval and baseline confounders (i.e., demographics, disease duration, and severity and progression rate). RESULTS: At retest, 100% and 69.2% of patients completed the ECAS and the MoCA, respectively. Patients who could not complete the MoCA showed a slightly more severe and fast-progressing disease. The MoCA was not subject to practice effects (t[32] = -0.80; p = 0.429) and was reliable at retest (intra-class correlation = 0.82). Moreover, baseline MoCA scores predicted the ECAS at retest. RCIs were successfully derived - with baseline MoCA scores being the only significant predictor of retest performances (ps < 0.001). CONCLUSIONS: As long as motor disabilities do not undermine its applicability, the MoCA appears to be longitudinally feasible at a 5-to-10-month interval in non-demented ALS patients. However, ALS-specific screeners - such as the ECAS - should be preferred whenever possible.

RESUMEN

Background: Psychosis, characterized by delusions and/or hallucinations, is frequently observed during the progression of Alzheimer's disease (AD) and other neurodegenerative dementias (ND) (i.e., dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD)) and cause diagnostic and management difficulties. Objective: This review aims at presenting a concise and up-to-date overview of psychotic symptoms that occur in patients with ND with a comparative approach. Methods: A systematic review was conducted following the PRISMA guidelines. 98 original studies investigating psychosis phenotypes in neurodegenerative dementias were identified (40 cohort studies, 57 case reports). Results: Psychosis is a frequently observed phenomenon during the course of ND, with reported prevalence ranging from 22.5% to 54.1% in AD, 55.9% to 73.9% in DLB, and 18% to 42% in FTD. Throughout all stages of these diseases, noticeable patterns emerge depending on their underlying causes. Misidentification delusions (16.6-78.3%) and visual hallucinations (50-69.6%) are frequently observed in DLB, while paranoid ideas and somatic preoccupations seem to be particularly common in AD and FTD, (respectively 9.1-60.3% and 3.10-41.5%). Limited data were found regarding psychosis in the early stages of these disorders. Conclusions: Literature data suggest that different ND are associated with noticeable variations in psychotic phenotypes, reflecting disease-specific tendencies. Further studies focusing on the early stages of these disorders are necessary to enhance our understanding of early psychotic manifestations associated with ND and help in differential diagnosis issues.

RESUMEN

BACKGROUND: The present study aimed at determining whether, net of motor confounders, neuropsychological features affect functional independence (FI) in activities of daily living (ADLs) in non-demented amyotrophic lateral sclerosis (ALS) patients. METHODS: N = 88 ALS patients without frontotemporal dementia were assessed for FI-Katz's Basic ADL Scale (BADL) and Lawton-Brody's Instrumental ADL Scale (IADL)-, cognition-Edinburgh Cognitive and Behavioural ALS Screen (ECAS)-and behaviour-Beaumont Behavioural Inventory and Dimensional Apathy Scale. The association between cognitive and behavioural measures and BADL/IADL scores was assessed by covarying for demographics, anxiety and depression levels, disease duration and motor confounders-i.e. ALS Functional Rating Scale-Revised (ALSFRS-R) scores, progression rate and both King's and Milano-Torino stages. RESULTS: Higher scores on the ECAS-Language were associated with higher IADL scores (p = 0.005), whilst higher apathetic features-as measured by the Dimensional Apathy Scale (DAS)-were inversely related to the BADL (p = 0.003). Whilst IADL scores were related to all ECAS-Language tasks, the DAS-Initiation was the only subscale associated with BADL scores. Patients with abnormal ECAS-Language (p = 0.023) and DAS (p = 0.008) scores were more functionally dependent than those without. DISCUSSION: Among non-motor features, language changes and apathetic features detrimentally affect FI in non-demented ALS patients.

RESUMEN

BACKGROUND: TDP-43 proteinopathies represent a spectrum of neurological disorders, anchored clinically on either end by amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). The ALS-FTD spectrum exhibits a diverse range of clinical presentations with overlapping phenotypes, highlighting its heterogeneity. This study was aimed to use disease progression modeling to identify novel data-driven spatial and temporal subtypes of brain atrophy and its progression in the ALS-FTD spectrum. METHODS: We used a data-driven procedure to identify 13 anatomic clusters of brain volume for 57 behavioral variant FTD (bvFTD; with either autopsy-confirmed TDP-43 or TDP-43 proteinopathy-associated genetic variants), 103 ALS, and 47 ALS-FTD patients with likely TDP-43. A Subtype and Stage Inference (SuStaIn) model was trained to identify subtypes of individuals along the ALS-FTD spectrum with distinct brain atrophy patterns, and we related subtypes and stages to clinical, genetic, and neuropathological features of disease. RESULTS: SuStaIn identified three novel subtypes: two disease subtypes with predominant brain atrophy in either prefrontal/somatomotor regions or limbic-related regions, and a normal-appearing group without obvious brain atrophy. The limbic-predominant subtype tended to present with more impaired cognition, higher frequencies of pathogenic variants in TBK1 and TARDBP genes, and a higher proportion of TDP-43 types B, E and C. In contrast, the prefrontal/somatomotor-predominant subtype had higher frequencies of pathogenic variants in C9orf72 and GRN genes and higher proportion of TDP-43 type A. The normal-appearing brain group showed higher frequency of ALS relative to ALS-FTD and bvFTD patients, higher cognitive capacity, higher proportion of lower motor neuron onset, milder motor symptoms, and lower frequencies of genetic pathogenic variants. The overall SuStaIn stages also correlated with evidence for clinical progression including longer disease duration, higher King's stage, and cognitive decline. Additionally, SuStaIn stages differed across clinical phenotypes, genotypes and types of TDP-43 pathology. CONCLUSIONS: Our findings suggest distinct neurodegenerative subtypes of disease along the ALS-FTD spectrum that can be identified in vivo, each with distinct brain atrophy, clinical, genetic and pathological patterns.

RESUMEN

Objectives: This study aimed at exploring (1) the motor and non-motor correlates of counterfactual thinking (CFT) abilities in non-demented amyotrophic lateral sclerosis (ALS) patients and (2) the ability of CFT measures to discriminate these patients from healthy controls (HCs) and patients with and without cognitive impairment. Methods: N = 110 ALS patients and N = 51 HCs were administered two CFT tasks, whose sum, resulting in a CFT Index (CFTI), was addressed as the outcome. Patients further underwent an in-depth cognitive, behavioral, and motor-functional evaluation. Correlational analyses were run to explore the correlates of the CFTI in patients. Logistic regressions were performed to test whether the CFTI could discriminate patients from HCs. Results: The CFTI was selectively associated (p ≤ 0.005) with fluency and memory subscales of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS), but not with other variables. CFTI scores discriminated patients from HCs (p < 0.001) with high accuracy (82%), but not patients with a normal vs. defective performance on the ECAS-Total. Conclusion: CFT measures in non-demented ALS patients were associated with verbal fluency and memory functions, and they were also able to discriminate them from HCs.

RESUMEN

Background: This study aimed at clarifying the role of bulbar involvement (BI) as a risk factor for cognitive impairment (CI) in non-demented amyotrophic lateral sclerosis (ALS) patients. Methods: Data on N = 347 patients were retrospectively collected. Cognition was assessed via the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). On the basis of clinical records and ALS Functional Rating Scale-Revised (ALSFRS-R) scores, BI was characterized as follows: (1) BI at onset-from medical history; (2) BI at testing (an ALSFRS-R-Bulbar score ≤11); (3) dysarthria (a score ≤3 on item 1 of the ALSFRS-R); (4) severity of BI (the total score on the ALSFRS-R-Bulbar); and (5) progression rate of BI (computed as 12-ALSFRS-R-Bulbar/disease duration in months). Logistic regressions were run to predict a below- vs. above-cutoff performance on each ECAS measure based on BI-related features while accounting for sex, disease duration, severity and progression rate of respiratory and spinal involvement and ECAS response modality. Results: No predictors yielded significance either on the ECAS-Total and -ALS-non-specific or on ECAS-Language/-Fluency or -Visuospatial subscales. BI at testing predicted a higher probability of an abnormal performance on the ECAS-ALS-specific (p = 0.035) and ECAS-Executive Functioning (p = 0.018). Lower ALSFRS-R-Bulbar scores were associated with a defective performance on the ECAS-Memory (p = 0.025). No other BI-related features affected other ECAS performances. Discussion: In ALS, the occurrence of BI itself, while neither its specific features nor its presence at onset, might selectively represent a risk factor for executive impairment, whilst its severity might be associated with memory deficits.

RESUMEN

The spectrum of neurodegenerative diseases that primarily affect cognition and behaviorspreads from asymptomatic preclinical disease to very mild cognitive impairment to frank dementia. Alzheimer's disease (AD) is the most common cause of a decline in cognitive ability. Also, it is a devastating condition that affects patients and their entirefamilies of caregivers, exacting tremendous financial hardships. Diagnosis may be complicated by other forms of dementia that have symptoms and pathologies similar to AD. Knowing the key features and pathology of each type of dementia can help in the accurate diagnosis of patients, so they will receive the treatment and support services appropriate for their condition and maintain the highest possible functioning in daily life and quality of life. Differentiate, based on clinical criteria, neuropathology, and biomarkers, AD and its atypical variants from other common dementias including Dementia with Lewy Bodies, Vascular Cognitive Impairment, Frontotemporal Degeneration, and less frequent cognitive disorders. The importance of getting an accurate and early diagnosis of dementiais now increasingly significant to make important decisions about treatment, support, and care. Nonpharmacological as well as pharmacological interventions should be initiated once the diagnosis is obtained. Biochemical markers to identify Alzheimer's disease play a central role in the new diagnostic criteria for the disease and in the recent biological definition of AD. This review article presents up-to-date data regarding the recent diagnostic criteria of Alzheimer´s disease and related disorders, emphasizing its usefulness in routine clinical practice.

El espectro de enfermedades neurodegenerativas que afectan principalmente a la cognición y el comportamiento abarca desde la enfermedad preclínica asintomática hasta el deterioro cognitivo muy leve y la demencia franca. La enfermedad de Alzheimer (EA) es la causa más común de deterioro de la capacidad cognitiva. Es una enfermedad devastadora que afecta a los pacientes y a toda su familia de cuidadores, lo que supone enormes dificultades socioeconómicas y psicoemocionales. El diagnóstico puede complicarse debido a otras formas de demencia que presentan síntomas y patologías similares a la EA. Los marcadores bioquímicos para identificar la enfermedad de Alzheimer desempeñan un papel central en los nuevos criterios diagnósticos de la enfermedad y en la reciente definición biológica de la EA. Conocer las características claves y la patología de cada tipo de demencia puede ayudar en el diagnóstico preciso de los pacientes, a fin de que reciban el tratamiento y los servicios de apoyo adecuados a su condición y mantengan el mayor funcionamiento posible en la vida diaria y la calidad de vida. Por lo tanto es prioritario diferenciar, basándose en criterios clínicos, neuropatología y biomarcadores, la EA y sus variantes atípicas de otras demencias comunes como el Deterioro Cognitivo Vascular, la Degeneración Fronto- temporal entre otras, y los trastornos cognitivos menos frecuentes. Este artículo de revisión presenta datos actualizados relativos a los recientes criterios diagnósticos de algunas formas de demencia haciendo hincapié en su utilidad en la práctica clínica habitual. Se exponen los criterios de EA, de Demencia Vascular (DV), de la demencia Fronto-temporal (DFT) y de una forma rara de demencia, descripta en los últimos años, que se evidencia en pacientes muy añosos con un perfil similar a la EA. Se trata de la encefalopatía predominantemente límbica por tdp- 43 relacionada a la edad (LATE).

RESUMEN

Traumatic brain injury (TBI) initiates tissue and cellular damage to the brain that is immediately followed by secondary injury sequalae with delayed and continual damage. This secondary damage includes pathological processes that may contribute to chronic neurodegeneration and permanent functional and cognitive deficits. TBI is also associated with an increased risk of developing neurodegenerative diseases such as Alzheimer's disease (AD), frontotemporal dementia (FTD), and amyotrophic lateral sclerosis (ALS) as indicated by shared pathological features. For example, abnormalities in the TAR DNA-binding Protein 43 (TDP-43) that includes cytoplasmic mislocalization, cytosolic aggregation, and an increase in phosphorylation and ubiquitination are seen in up to 50% of FTD cases, up to 70% of AD cases, and is considered a hallmark pathology of ALS occurring in > 97% of cases. Yet the prevalence of TDP-43 pathology post-TBI has yet to be fully characterized. Here, we employed a non-transgenic murine controlled cortical injury model of TBI and observed injury-induced hallmark TDP-43 pathologies in brain and spinal cord tissue distal to the primary injury site and did not include the focally damaged tissue within the primary cortical injury site. Analysis revealed a temporal-dependent and significant increase in neuronal TDP-43 mislocalization in the cortical forebrain rostral to and distant from the primary injury site up to 180 days post injury (DPI). TDP-43 mislocalization was also detected in neurons located in the ventral horns of the cervical spinal cord following a TBI. Moreover, a cortical layer-dependent affect was identified, increasing from superficial to deeper cortical layers over time from 7 DPI up to 180 DPI. Lastly, RNAseq analysis confirmed an injury-induced misregulation of several key biological processes implicated in neurons that increased over time. Collectively, this study demonstrates a connection between a single moderate TBI event and chronic neurodegenerative processes that are not limited to the primary injury site and broadly distributed throughout the cortex and corticospinal tract.

RESUMEN

With the increasing availability of predictive genetic testing for adult-onset neurodegenerative conditions, it is imperative that we better understand the impact of learning one's risk status. Frontotemporal degeneration (FTD) is the second most prevalent cause of early-onset dementia. About one-third of patients have an identifiable genetic etiology, and some genetic variants that cause FTD can also cause amyotrophic lateral sclerosis (ALS). To understand individuals' risk perception and broader experience of living at risk, we completed semi-structured telephone interviews with 14 asymptomatic adults who tested positive for a variant known to cause risk for FTD and/or ALS. We conducted a thematic analysis, and within the core topic of identity, we derived three themes: conceptualization of FTD and ALS as a threat to identity, enduring uncertainty and dread, and varying centrality of risk status to identity. FTD and ALS risk raised fundamental issues for participants related to the essence of personhood, challenged them to confront Cartesian dualism (the philosophy of mind-body separation), and exposed how time, relationships, and social roles have affected their understanding of the nature of the self. Our findings provide important insight into how being at genetic risk shapes an individual's identity. We conclude that genetic counseling interventions that allow for identity exploration, anticipatory guidance, and uncertainty management should be utilized when supporting persons at risk.

RESUMEN

Proteinopathy and neuroinflammation are two main hallmarks of neurodegenerative diseases. They also represent rare common events in an exceptionally broad landscape of genetic, environmental, neuropathologic, and clinical heterogeneity present in patients. Here, we aim to recount the emerging trends in amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD) spectrum disorder. Our review will predominantly focus on neuroinflammation and systemic immune imbalance in ALS and FTD, which have recently been highlighted as novel therapeutic targets. A common mechanism of most ALS and ~50% of FTD patients is dysregulation of TAR DNA-binding protein 43 (TDP-43), an RNA/DNA-binding protein, which becomes depleted from the nucleus and forms cytoplasmic aggregates in neurons and glia. This, in turn, via both gain and loss of function events, alters a variety of TDP-43-mediated cellular events. Experimental attempts to target TDP-43 aggregates or manipulate crosstalk in the context of inflammation will be discussed. Targeting inflammation, and the immune system in general, is of particular interest because of the high plasticity of immune cells compared to neurons.

RESUMEN

The diagnosis of frontotemporal degeneration changes the entire family, being an unexpected and emotionally burdening experience for all the individuals in the family. Confrontation with problems that are diametrically different from those that occur in the family system without a person with a major neurocognitive disorder requires the development of new coping strategies. If these coping mechanisms are to be useful, they should undergo successive modifications that consider the progression of the neurodegenerative disease and the dynamics of the family system. Providing the information on different aspects of this group of diseases is the basic form of supporting families with frontotemporal degeneration. Growing up in the family with a parent affected by frontotemporal degeneration is a crucial, though non-normative, developmental experience of a child. It results in an irreversible loss of the existing relationship and the necessity to form another relationship with an affected parent. The paper focuses on providing support for a minor. Graphic medicine can be a support tool, which combines verbal communication with graphics, and, as a result, it provides knowledge on health problems and also creates the possibility of expressing emotions triggered by the presence of the disease in the family.

RESUMEN

The present study aimed at deriving, by means of a traditional "2 standard deviation-based" (2SD) approach, single task-level cutoffs for the Italian version of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Cutoffs were derived - as M-2*SD - from the sample of healthy participants (HPs) included within 2016 Poletti et al.'s normative study - N = 248; 104 males; age: 57.8 ± 10.6; education: 14.1 ± 4.6 - separately for the four, original demographic classes: 1) education <14 years and age ≤60 years; 2) education <14 years and age >60 years; 3) education ≥14 years and age ≤60 years; 4) education ≥14 years and age >60 years. The prevalence of deficits on each task was then estimated within a cohort of N = 377 amyotrophic lateral sclerosis (ALS) patients without dementia. The distribution of abnormal performance prevalences was overall consistent with the cognitive phenotype of ALS. In conclusion, the single task-level cutoffs herewith provided for the Italian version of the ECAS, which complement those already available within Poletti et al.'s normative framework, will help better profile Italian ALS patients' cognitive phenotype within both clinical and research settings.

RESUMEN

Introduction: A tremendous burden is placed on frontotemporal degeneration (FTD) caregivers who sacrifice their own self-care to manage the functional impairments of their loved one, contributing to high levels of stress and depression. Health coaching provides support for coping with stress while fostering self-care behaviors. We report on preliminary evidence for efficacy of a virtual health coach intervention aimed at increasing self-care. Methods: Thirty-one caregivers of persons with behavioral variant FTD (bvFTD) were assigned randomly to an intervention group, which included 10 coaching sessions over 6 months plus targeted health information or the control group receiving standard care augmented with the health information. Caregiver self-care (primary outcome), stress, depression, coping, and patient behavioral symptoms were collected at enrollment and 3 and 6 months. Change over time was evaluated between the intervention and control groups using linear mixed-effects models. Results: There was a significant group-by-time interaction for self-care monitoring (t58 = 2.37, p = 0.02 and self-care confidence (t58 = 2.32, p = 0.02) on the Self-Care Inventory, demonstrating that caregivers who received the intervention improved their self-care over time. Behavioral symptoms were reduced in bvFTD patients whose caregivers received the intervention (t54 = -2.15, p = 0.03). Discussion: This randomized controlled trial (RCT) shows promise for health coaching as a way to increase support that is urgently needed to reduce poor outcomes in FTD caregivers.

RESUMEN

Objective: There are limited studies exploring the support and education needs of individuals at-risk for or diagnosed with hereditary frontotemporal degeneration (FTD) and/or amyotrophic lateral sclerosis (ALS). This study evaluated a novel conference for this population to assess conference efficacy, probe how participants assessed relevant resources, and identify outstanding needs of persons at-risk/diagnosed. Methods: We implemented a post-conference electronic survey that probed participants' satisfaction, prior experience with resources, and unmet needs. Along with multiple-choice, free-text items were included to gather qualitative context. Results: Survey completion rate was 31% (115/376 attendees who were emailed the survey). There was positive interest in pursuing genetic counseling among eligible responders: 61% indicated they planned to seek genetic counseling because of the conference, which was significantly more than those who were undecided (21%) or did not plan to seek genetic counseling (18%). Qualitative data demonstrated need for additional education, support, and research opportunities. Conclusion: Conference reactions indicate this is a valued resource. Results indicated the importance of raising awareness about existing resources, and the need for further resource development, especially for at-risk communities. Innovation: While most resources are developed for caregivers' needs, this unique program targets at-risk individuals and unites ALS and FTD communities.

RESUMEN

BACKGROUND: The present study aimed at deriving equating norms to estimate scores on the Edinburgh Cognitive and Behavioural ALS Screen (ECAS) based on those on the ALS Cognitive Behavioral Screen (ALS-CBS™) in an Italian cohort of non-demented ALS patients. METHODS: ALS-CBS™ and ECAS scores of 293 ALS patients without frontotemporal dementia were retrospectively retrieved. Concurrent validity of the ALS-CBS™ towards the ECAS was tested by covarying for demographics, disease duration and severity, presence of C9orf72 hexanucleotide repeat expansion and behavioural features. A linear-smoothing equipercentile equating (LSEE) model was employed to derive ALS-CBS™-to-ECAS cross-walks. Gaps in LSEE-based estimation were managed via a linear regression-based equating approach. Equivalence between empirical and derived ECAS scores was tested via a two-one-sided test (TOST) procedure for the dependent sample. RESULTS: The ALS-CBS™ predicted the ECAS (ß = 0.75), accounting for the vast majority of its variance (60% out of an R2 = 0.71). Consistently, a strong, one-to-one linear association between ALS-CBS™ and ECAS scores was detected (r = 0.84; R2 = 0.73). The LSEE was able to estimate conversions for the full range of the ALS-CBS™, except for raw scores equal to 1 and 6 - for whom a linear equating-based equation was derived. Empirical ECAS scores were equivalent to those derived with both methods. DISCUSSION: Italian practitioners and researchers have been herewith provided with valid, straightforward cross-walks to estimate the ECAS based on ALS-CBS™ scores in non-demented ALS patients. Conversions herewith provided will help avoid cross-sectional/longitudinal inconsistencies in test adoption within research, and possibly clinical, settings.
