Delusions and hallucinations in frontotemporal dementia: a clinicopathologic case report.
BACKGROUND
Frontotemporal dementia (FTD) is associated with marked behavior changes, but hallucinations and delusions are rare.


OBJECTIVE
To report a case of FTD with early and persistent delusions, including de Clerambault syndrome.


METHODS
We describe the clinical, neuroradiologic, and neuropathologic findings of a 76-year-old woman with an 11-year course of FTD with bizarre delusions and hallucinations.


RESULTS
The patient's autopsy examination of the brain revealed pathology consistent with frontotemporal lobar degeneration with ubiquitin-positive and transactive response (TAR)-DNA-binding protein-43-positive inclusions and hippocampal sclerosis.


CONCLUSIONS
Delusions and hallucinations can occur in proven frontotemporal pathology.
