An autosomal recessive disease characterized by presenile frontal dementia with leukoencephalopathy and basal ganglia calcification. In most cases the disorder first manifests in early adulthood as pain and swelling in ankles and feet, followed by bone fractures. Neurologic symptoms manifest in the fourth decade of life as a frontal lobe syndrome with loss of judgment, euphoria, and disinhibition. Progressive decline in other cognitive domains begins to develop at about the same time. The disorder culminates in a profound dementia and death by age 50 years.

Multimodal semantic knowledge of emotion concepts in frontotemporal dementia.

medRxiv : the preprint server for health sciences2026 Jan 13

Recent work has delineated the semantic behavioral variant of frontotemporal dementia (sbvFTD; or right temporal variant of FTD, which is thought to preferentially impair semantic knowledge for emotional concepts. However, this proposed core feature has not yet been empirically validated, and no clinical tool exists to assess it. Establishing reliable markers is essential to clinically differentiate sbvFTD from behavioral variant FTD (bvFTD), which is critical given their overlapping behavioral symptoms but divergent underlying pathologies. Furthermore, contrasting sbvFTD with semantic variant primary progressive aphasia (svPPA) can advance our understanding of semantic memory, revealing how the right and left anterior temporal lobes (ATLs) support emotion- versus tool-related knowledge, highlighting the graded, lateralized organization of the semantic system. We studied 15 patients with sbvFTD, 15 with svPPA, 18 with bvFTD, and 37 healthy controls. A novel multimodal semantic battery, the Fear and Spider Test (FST), which assesses tool- and emotion-related concepts across word-based semantic associations, picture-based semantic associations, and sound-to-picture matching, was administered. Stimuli were matched on psycholinguistic and perceptual features, and emotional items were drawn from multicultural facial expressions validated with the Facial Action Coding System. Neural correlates of semantic performance were investigated using voxel-based morphometry. As expected, patients with both sbvFTD and svPPA showed greater deficits in all semantic tasks compared to controls and bvFTD, and bilateral anterior temporal lobe (ATL) volumes were broadly associated with performance across all semantic tasks. Interactions between modality and categories were necessary for the emergence of differences between sbvFTD and svPPA and right and left ATL atrophy: performance on the Words-Tools condition was more impaired in svPPA and correlated with left ATL volume, while performance on the Pictures-Emotions condition was more impaired in sbvFTD and correlated with right ATL volume. The FST provides the first clear dissociation of sbvFTD from bvFTD, a distinction of critical clinical importance given their divergent pathological substrates and the absence of frontotemporal lobar degeneration specific biomarkers. The study also refines our understanding of semantic memory: contrasting sbvFTD with svPPA reveals complementary roles of the right and left ATLs in supporting emotion and tool knowledge, underscoring the graded, lateralized organization of the semantic system.

CSF1R mutations in an Italian population of early-onset dementia: a case series.

Journal of neurology2026 Feb 04

The diagnostic approach to subjects with early-onset dementia (EOD) is often challenging due to the broader range of possible etiologies as compared to late-onset dementia cases. Pathogenic variants in CSF1R gene have been increasingly reported in subjects with EOD, mostly clinically mimicking behavioral variant of frontotemporal dementia (bvFTD). Here we screened for variants in CSF1R gene in a large cohort of dementia patients consecutively referred for genetic analysis to an Italian tertiary center between 2005 and 2024 (n = 2163). Sequence of CSF1R gene was determined with next-generation sequencing through either a dedicated panel or whole-exome sequencing. Pathogenic variants or variants of uncertain significance with higher evidence of pathogenicity were found in four participants (one female); three of these were not previously reported. Clinical data were collected, including brain magnetic resonance imaging and neuropsychological assessment. Cerebrospinal fluid (CSF) levels of neurofilament light chain (NfL) protein were measured. A family history of dementia was present in one subject. Mean age at onset was 51.5. Seizures were the presenting symptom in two cases and later appeared in other two. Two subjects presented with behavioral disturbances, resembling early bvFTD. Neuropsychological assessment revealed executive and language impairment in most cases. Anterior-predominant atrophy, symmetric white-matter involvement, and serpentine calcifications were the most common imaging abnormalities. High CSF NfL levels were found in all cases, with two of them showing markedly elevated values. CSF1R-related disease should be considered in EOD subjects, especially those presenting with executive/language deficits, seizures, white matter involvement, and markedly elevated CSF NfL levels.

Exploring neuropsychiatric and behavioral symptoms, and social cognitive deficits in the differential diagnosis of behavioral variant of frontotemporal dementia and primary psychiatric disorders: A systematic literature review.

Alzheimer's &amp; dementia (Amsterdam, Netherlands)2026

The clinical overlap between behavioral variant frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPD) often results in delayed and incorrect diagnoses. We performed a literature review of 16 studies to evaluate how neuropsychiatric, behavioral, and social cognitive symptoms can aid in distinguishing bvFTD from PPD during early clinical assessment. Our study revealed differences in symptom profile and trajectory in the two diseases. Apathy, disinhibition, and compulsions were more likely to progress in bvFTD, while often remaining stable or improving in PPD. Changes in eating behavior and inappropriate social conduct, and emotion recognition, socioemotional sensitivity, and theory-of-mind impairments were more severe in bvFTD than in PPD. Although differential diagnosis can be challenging, studying the profile and progression of neuropsychiatric, behavioral, and social cognitive symptoms in bvFTD and PDD offers valuable diagnostic clues. Implementing structured tools and targeted assessments may improve differential diagnosis, ultimately guiding more appropriate treatment strategies.

Repetitive behaviors in syndromes associated with frontotemporal lobar degeneration.

Journal of Alzheimer's disease : JAD2026 Mar

BackgroundRepetitive behaviors (RB) are purposeless movements, speech, or routines performed without self-awareness or conscious intent.ObjectiveThe present study aims to investigate the prevalence and longitudinal changes of RB and to assess these symptoms in a large cohort of patients with frontotemporal lobar degeneration (FTLD)-associated syndromes using a newly developed caregiver-based questionnaire.MethodsThis was a longitudinal cohort study conducted in tertiary frontotemporal dementia research clinics. A total of 210 FTLD patients were included, 68 of whom had follow-up evaluation. RB were assessed through structured caregiver interviews. Compulsive/impulsive behaviors, stereotypies, and ritualistic behaviors were recorded. Univariate and multiple generalized linear models and generalized linear mixed models were used to estimate predictors and longitudinal changes associated with RB.ResultsRB were reported in 71% of patients, showing a progressive increase from the prodromal to moderate dementia stages. Notably, 30% of patients presented RB since the disease onset phase, especially in the form of compulsive/impulsive behaviors. Predictors included male gender, the behavioral variant of frontotemporal dementia and the semantic variant of primary progressive aphasia phenotypes, and higher scores on Frontal Behavioral Inventory scale, part B. A significant increase in total RB was observed in patients reassessed at 8 to 22 months follow-up from baseline (p = 0.0001), especially in the form of stereotypies and ritualistic behaviors.ConclusionsThe questionnaire developed in this study effectively captures the prevalence and progression of RB. It could contribute to the standardization of the behavioral assessment in FTLD clinical trials and, consequently, to a deeper understanding of these syndromes.

A Psychosocial Intervention for Managing Disinhibition in People With the Behavioral Variant of Frontotemporal Dementia: A Matter of Focusing.

Journal of the American Medical Directors Association2026 Mar

Management of disinhibited behavior in people with the behavioral variant of frontotemporal dementia is challenging. To support health care professionals in long-term care, we developed "Focusing," a psychosocial intervention based on theory of automatic behavior, stimulus processing, and resident-staff interactions. The intervention was evaluated for feasibility and limited efficacy with a replicated single-case A-B observation study in 6 cases, and using questionnaires and interviews with health care professionals. The intervention was feasible in all cases and a decrease in disinhibited behavior was observed following the introduction of the intervention in 4 cases. Professionals deemed the intervention highly relevant, as they perceive disinhibition as a complex problem. These results form a foundation for larger-scale evaluation of effectiveness and show promise of the intervention for further implementation in clinical practice.
