Similarly, FDG-PET/CT found bilateral moderate/severe anterior temporal, anterior cingulate and frontal hypometabolism consistent with BvFTD. In addition, there was mild/moderate hypometabolism in the parietal, posterior cingulate and precuneus cortex bilaterally making it impossible to unequivocally exclude AD. The patient died 4 months later and brain autopsy was performed. There were low/intermediate pathologic changes of AD with neuritic plaques but a low Braak stage (A1, B1, C3 by NIA-AA criteria). This level of AD pathology is insufficient to account for dementia. Immunohistochemistry demonstrated numerous ubiquitin neuronal and glial inclusions that did not co-localize with tau pathology. Immunohistochemistry for TDP-43 was subsequently performed revealing intraneuronal cytoplasmic inclusions. Genetic testing found a tau variant associated with both AD and FTD.Conclusions: Advanced age does not exclude FTD and should be considered in the differential diagnosis, even in the oldest-old. Further, multiple pathologies are common in the oldest old. Advanced brain imaging including MRI, FDG-PET can help identify non-AD dementias in elderly.Disclosure: Dr. Embree has nothing to disclose.
