Frontotemporal lobar degeneration complexity: atypical presentations and heterogeneous proteinopathies in five cases.
Frontotemporal lobar degeneration (FTLD) encompasses heterogeneous clinical syndrome within the frontotemporal spectrum, where clinicopathological associations may be misleading. This case series illustrates clinicopathological variability and mismatches. A retrospective case series was conducted within the brain donation program at the Golgi Cenci Foundation. Cases presenting at onset with a frontotemporal-spectrum phenotype, longitudinal clinical data, and post-mortem neuropathological characterization were included. Five cases (mean age at onset 65.4 years) were clinically diagnosed with major neurocognitive disorder due to frontotemporal dementia (FTD). Neuropathological examination revealed clinicopathological heterogeneity: two cases showed FTLD-TDP-A associated with GRN mutations, including a classic case and one with posterior (parieto-occipital) involvement; one non-fluent variant primary progressive aphasia (nfvPPA) case demonstrated FTLD-TDP-A with multiple co-pathologies; one semantic-variant-like case was driven by high Alzheimer's disease neuropathological changes; and one behavioral variant FTD-like case corresponded to frontal-variant Alzheimer's disease (fvAD) with extensive mixed pathology, including Lewy body disease, LATE-NC, and vascular pathology. Findings indicate that clinical phenotypes are more influenced by the anatomical distribution of pathology than by the specific molecular substrate. Frequent coexisting proteinopathies and asymmetric involvement contribute to phenotypic variability, reinforcing the role of neuropathological examination of both hemispheres for accurate clinicopathological correlations and definitive etiological diagnosis.
[A case of progressive supranuclear palsy with progressive non-fluent agrammatic variant primary progressive aphasia who could sing fluently].
The patient was a 65-year-old man. He visited the hospital complaining of gait disturbances and difficulty speaking. He was diagnosed with progressive supranuclear palsy because of slow vertical eye movements, frequent falls, and freezing gait; these symptoms were levodopa-resistant. The patient also had aphasia similar to non-fluent agrammatic variant of primary progressive aphasia, stuttering, and palilalia. However, he was able to sing a familiar song fluently. In contrast, for an unfamiliar song, he could not begin singing without the lyrics, and was more accurate at reading aloud than singing. Nonfluent aphasia with preserved singing ability has been reported in patients with stroke and trauma. However, this has rarely been reported for neurodegenerative diseases. This phenomenon may be due to the functional preservation of the right hemisphere and the left temporal lobe. The familiar song may have been stored in long-term memory as a set of lyrics and melody, and he may have produced it as automatic language.
Enhanced diagnostic interpretation of the MoCA using machine learning.
Artificial Intelligence (AI) is increasingly being integrated into clinical practice to optimize diagnosis in neurocognition. By capturing distinct cognitive signatures, this approach may offer a more precise alternative to the traditional interpretation of the Montreal Cognitive Assessment (MoCA) which often relies on a fixed cutoff score (26/30). We aimed to evaluate whether machine learning models, by integrating detailed MoCA subtest scores, demographic variables, and cognitive chart-derived metrics, can improve the detection of cognitive impairment and classification of dementia subtypes. We analyzed 38,746 clinical observations (17,188 unique individuals) from the National Alzheimer's Coordinating Center database. Five supervised learning algorithms, Extreme Gradient Boosting (XGBoost), Random Forest, Support Vector Machine (SVM), Logistic Regression, and k-Nearest Neighbors (KNN), were trained using detailed MoCA subtest scores, demographic variables, and cognitive chart-derived metrics as predictors. To ensure generalizability of results and prevent data leakage, we applied a rigorous nested Repeated Grouped Cross-Validation strategy. Decision thresholds were optimized via the Youden Index on independent calibration sets, and model interpretability was ensured through SHAP value analysis. Machine learning models consistently outperformed conventional approach. For the global detection of cognitive impairment, XGBoost achieved the best performance (Youden Index 0.61 vs. 0.54 for the standard cutoff). Regarding subtype classification, models demonstrated variable discriminative capacity depending on clinical homogeneity: primary progressive aphasia was best classified (Youden ≈ 0.77), followed by Lewy body dementia and Alzheimer's disease, while vascular dementia remained more challenging to isolate. Feature importance analysis highlighted the Cognitive Quotient as a robust universal predictor, while pinpointing disease-specific drivers such as delayed recall for Alzheimer's disease and verbal fluency for primary progressive aphasia. Our findings suggest interpretable machine learning enhances diagnostic utility of the MoCA, yielding superior accuracy compared to a fixed cutoff. By synthesizing individualized subtest profiles within a transparent framework, this approach offers a clinically actionable solution. It transforms the MoCA from a simple screening tool to a precision diagnostic aid, optimizing patient triage in the era of disease-modifying therapies.
White Matter Hyperintensities in Behavioral Variant Frontotemporal Dementia and Semantic Variant Primary Progressive Aphasia.
White matter hyperintensities (WMH) in patients with cerebrovascular risk factors (CVRF), are often linked to cerebral vascular changes, but can be caused by genetic variants selectively targeting white matter. In addition, WMH can be present in neurodegenerative disorders such as frontotemporal lobar degeneration (FTLD) and are linked to some FTLD genetic variants. This study aims to investigate WMH burden in patients with behavioral variant frontotemporal dementia (bvFTD) and semantic variant primary progressive aphasia (svPPA) versus controls and to evaluates the influence of CVRF. This cross-sectional retrospective analysis examined individuals meeting research diagnostic criteria for bvFTD and svPPA with high-quality structural MRI at the UCSF Memory and Aging Center between September 2008 and December 2021. WMH burden and spatial distribution were assessed by disease group compared to age- and sex-matched controls and associations with CVRF evaluated. We included 109 individuals with bvFTD [mean age (SD) 62.9 (8.6), 40% female], 47 with svPPA [mean (SD) age 65.4 (7.5), 51% female], and matched controls. After adjusting for age, apolipoprotein E4 (APOE-ε4) status and intracranial volume (ICV), both disease groups had higher WMH burden compared to controls (bvFTD, R 2 =0.184, p=0.001 and svPPA, R 2 =0.323, p=<0.001). Compared to controls, bvFTD group had more prevalent WMH in the frontal lobe (β=0.403 ; 95% CI 0.27 to 0.54 , p=<0.001), while those with svPPA had more prevalent WMH in the frontal (β=0.462 ; 95% CI 0.26 to 0.66, p <0.001), parietal (β=0.772 ; 95% CI 0.50 to 1.04, p <0.001), temporal (β=0.674 ; 95% CI 0.44 to 0.91, p <0.001), occipital lobes (β=0.364 ; 95% CI 0.14 to 0.59, p=0.002), and corpus callosum (β=0.342 ; 95% CI 0.13 to 0.55, p=0.002). In disease groups, WMH were not significantly associated with CVRF (F=0.468, df=2, p=0.641) suggesting a potential role of non-vascular mechanisms. We did not identify associations between the pathogenic C9orf72 hexanucleotide repeat expansions (HRE) and WMH in bvFTD patients. bvFTD and svPPA are associated with elevated WMH burden independent of CVRF. In bvFTD, WMH are primarily distributed within the frontal lobes, while svPPA shows widespread distribution across lobes. Study limitations include its retrospective, single-center design and limited power for genetic subgroup analyses.
Transcriptomic signature of frontotemporal lobar degeneration with TDP-43 type C pathology.
Semantic variant of primary progressive aphasia is a clinical subtype of frontotemporal lobar degeneration and is marked by TDP-43 subtype C pathology (FTLD-TDP C). It is a sporadic disease, yet has a strikingly homogeneous clinicopathological presentation, suggesting a common pathophysiology. The aim of this study was to discover dysregulated pathways in FTLD-TDP C through transcriptomics of the temporal cortex, its most affected region. Bulk RNA sequencing was conducted on temporal cortices of a post-mortem cohort of 18 FTLD-TDP C patients and 23 sex- and age-matched controls. Differential expression and functional analyses were run to detect differentially expressed genes with FDR<0.05 (DEG) and functionally annotate them. We assessed enrichment of TARDBP's protein interactors and RNA targets in DEG. Our findings were compared to other published RNA sequencing data of tauopathies (Alzheimer's dementia, progressive supranuclear palsy and FTLD with MAPT), FTLD-TDP (subtypes A&B) and available proteomics of this cohort. Furthermore, we performed weighted gene co-expression network analysis (WGCNA). We adjusted for differences in cell type composition between cases and controls using cell deconvolution, and removed genes dysregulated in temporal cortices of other datasets. In DEG of FTLD-TDP we focused on enrichment of synaptic processes using SynGO. We found upregulation of damage response, cell structure, RNA splicing processes and downregulation of synaptic processes in 6322 DEG and five disease-related WGCNA modules. TARDBP-related genes were enriched in DEG. Additionally, transmembrane transport across the neurovascular unit was dysregulated. After cell deconvolution and removal of common tau-genes, postsynaptic processes remained dysregulated, specifically gene ontology terms 'modulation of chemical synaptic transmission' and 'neurotransmitter receptor localisation to postsynaptic specialisation membrane'. We found eleven synaptic FTLD-TDP C-specific genes affected on both RNA- and protein-level in the temporal cortex, which were involved in synaptic adhesion (CADM1, NCAN), signal transmission (COMT, RGS144, SLC1A2, TUBB2B) and synaptic plasticity (BEGAIN, ITPKA, LRFN1, RAB3B, SYNPO). In conclusion, a wide range of processes were dysregulated on RNA-level in the temporal cortex of FTLD-TDP C, including commonly affected processes in neurodegeneration, such as structural cell alterations. Dysregulation of TARDBP-related genes and RNA splicing has also been observed in other TDP-43 proteinopathies. Importantly, we found that postsynaptic processes were downregulated in FTLD-TDP C, after removing tauopathy-related genes and after cell deconvolution. In particular, assembly of receptors at the postsynaptic membrane and synaptic signal transmission were affected, both on RNA and protein level. Future research on these pathways could elucidate distinct pathophysiological mechanisms and guide targeted clinical approaches.
