Interpretation Our results indicate that neuropsychiatric features are normal in FTLD and type an important sign of root pathology. To be able to enable better addition of sufferers in targeted molecular studies, the regular GSK-923295 evaluation of sufferers with frontotemporal dementia will include the existence and nature of neuropsychiatric symptoms. ANN NEUROL 2020;87:950C961 The term frontotemporal dementia (FTD) defines a group of neurodegenerative syndromes with diverse clinical presentations, including the behavioral variant of frontotemporal dementia (bvFTD) and language dominant syndromes, such as main progressive aphasia (PPA), including the nonfluent/agrammatic variant of PPA (nfPPA), and the semantic variant of PPA (svPPA).1, 2 Other syndromes that are part of this group are characterized by prominent movement symptoms, such as corticobasal syndrome, progressive supranuclear palsy, and FTD with motor neuron disease. Most patients present with mixed behavior, language, and motor symptoms, but are diagnosed based on their most pronounced and first onset of symptoms and/or behavior. The past decade has seen a fast development of knowledge around the clinical and genetic features of FTD. In 2011, diagnostic criteria for bvFTD and PPA were revised which improved diagnostic accuracy.1, 2 Mutations in genes, such as chromosome 9 open reading frame 72 GSK-923295 (repeat expansion service providers and noncarriers.4, 5, 6 Due to the clinical variability and overlap of symptoms with main psychiatric diseases and other neurodegenerative diseases, such as Alzheimer’s disease, and given the lack of biomarkers, it remains challenging to diagnose FTD accurately in a clinical setting. The pathology of FTD, termed frontotemporal lobar degeneration (FTLD), is usually characterized by the unifying GSK-923295 macroscopic hallmark of atrophy of the frontal and temporal lobes.7 On a microscopic level, aggregates of distinct types of misfolded proteins can be observed. TAR DNA\binding protein\43 (TDP\43) aggregates occur in approximately 50% of patients, microtubule associated protein tau (MAPT) in GSK-923295 GSK-923295 40%, and fused in sarcoma (FUS) aggregates are seen in 5 to 10%.7, 8 and mutations are associated with TDP\43 aggregation, whereas mutations in lead to tau aggregation.5 Within the molecular class TDP\43, 5 different histotypes (A\E) have been described based on the morphology and distribution of cytoplasmic and neuritic aggregates across brain layers.9 TDP\C is the predictable histopathology in the majority Col4a4 of patients with svPPA.10 However, in the remaining sporadic patients with FTD, the underlying phenotype can scarcely be predicted based on the clinical phenotype. Previous efforts to identify clinicopathological correlations in FTD focused on the underlying pathologies of the FTD clinical subgroups.10, 11, 12, 13, 14, 15, 16, 17 When focusing on the 5 core behavioral symptoms of bvFTD, predicting the underlying pathological phenotype remains challenging.18 Here, we set out to investigate clinicopathological correlations at the symptom level in a large FTD cohort encompassing all clinical variants, and include a broader spectrum of symptoms than those that have been incorporated in the consensus clinical criteria, such as neuropsychiatric symptoms.
