The Impact

Background: The criteria for behavioral variant frontotemporal dementia (bvFTD) incorporate MRI and [18F]-FDG-PET. Cerebrospinal fluid (CSF) analysis is merely advised for excluding Alzheimer's disease. Aims: We aimed to assess the impact of biomarkers on diagnostic certainty and contingent changes of bvFTD diagnosis within the clinically relevant neuropsychiatric differential diagnosis of subjects with a late-onset frontal lobe syndrome (LOF). Methods: We included 137 patients with LOF, aged 45-75 years, 72% males. Biomarker disclosure was considered contributing after any substantial difference in diagnostic certainty or a diagnostic change. Percentages of contributing biomarkers were compared between three major diagnostic groups (bvFTD, psychiatry, other neurological disorders). Certainty levels in stable diagnostic groups were compared to those with a diagnostic change. Results: Biomarkers contributed in 53, 60 and 41% of the LOF patients for MRI, [18F]-FDG-PET and CSF, respectively. Biomarkers changed the diagnosis in 14% of cases towards bvFTD and in 13% from bvFTD into an alternative. Those that changed had a lower level of a priori diagnostic certainty compared to stable diagnoses. Conclusion: Our study not only supports the widely accepted use of MRI and [18F]-FDG-PET in diagnosing or excluding bvFTD, but also shows that CSF biomarkers aid clinicians in the diagnostic process.

Frontal Lobe Syndrome

Background/Aims: We aimed to prospectively assess the diagnostic accuracy of the revised criteria for behavioural variant frontotemporal dementia (bvFTD) among subjects presenting with a frontal lobe syndrome in middle-late adulthood. Methods: Patients were included based on a predominant behavioural clinical presentation, a Frontal Behavioural Inventory (FBI) score of ≥11 and/or a Stereotypy Rating Inventory (SRI) score of ≥10. At baseline, the fulfilment of the international consensus criteria for behavioural variant FTD (FTDC) was systematically recorded. The 2-year follow-up consensus diagnosis was used as the gold standard to calculate sensitivity and specificity of the FTDC criteria for possible and probable bvFTD. Results: Two-year follow-up data were available for 116 patients (85%). Two-year follow-up consensus diagnoses consisted of probable/definite bvFTD (n = 27), other dementia (n = 30), psychiatric disorders (n = 46) and other neurological disorders (n = 13). Sensitivity for possible bvFTD was 85% (95% CI 70-95%) at a specificity of 27% (95% CI 19-37%). Sensitivity for probable bvFTD was 85% (95% CI 69-95%), whereas their specificity was 82% (95% CI 73-89%). Conclusions: We found a good diagnostic accuracy for FTDC probable bvFTD. However, the specificity for FTDC possible bvFTD was low. Our results reflect the symptomatic overlap between bvFTD, other neurological conditions and psychiatric disorders, and the relevance of adding neuroimaging to the diagnostic process.

Frontal Lobe Syndrome

ABSTRACTA late onset frontal lobe syndrome (LOF) refers to a clinical syndrome with apathy, disinhibition, or stereotypical behavior arising in middle or late adulthood. Diagnostics are challenging, and both clinicians and patients need reliable predictors of progression to improve clinical guidance. In this longitudinal multicenter and genetically screened prospective study, 137 LOF patients with frontal behavior (FBI score≥11) and/or stereotypical behavior (SRI≥10) were included. Progression was defined as institutionalization, death, or progression of frontal or temporal atrophy at magnetic resonance imaging (MRI) after two years of follow up. Absence of progression at MRI in addition to stable or improved Mini Mental State Examination and Frontal Assessment Battery scores after two years was indicative for non-progression. The presence of stereotypy and a neuropsychological profile with executive deficits at baseline were found to be predictive for progression, while a history and family history with psychiatric disorders were predictors for non-progression. The combination of these clinical markers had a predictive value of 80.4% (p < 0.05). In patients presenting with late onset behavioral symptoms, an appraisal of the rate of deterioration can be made by detailed mapping of clinical symptoms. Distinction of progressive discourses from non-progressive or treatable conditions is to be gained.

ABSTRACT Current concepts regarding frontotemporal lobar degeneration (FTLD) have evolved rapidly in recent years. Genetically determined FTLD cohorts have broadened our knowledge pertaining to its clinical presentation, neuroimaging findings and demographics. In this study we present a case report of a patient diagnosed with behavioral variant frontotemporal dementia diagnosis in her nineties during hospital admission for a ground-level fall. We believe this case reinforces the pervasive nature of this clinical entity, and may contribute to an increased awareness of this diagnostic possibility in late-onset dementia.
