Abstract
-
BACKGROUND: It is not uncommon to misdiagnose frontotemporal dementia (FTD) because it presents with alterations in personality and behavior rather than cognitive decline. Since compulsive behavior is one of the common early manifestations of FTD, analysis of compulsive behaviors, together with presenting symptoms, would help diagnose FTD in its early stage.
METHODS
Subjects consisted of 25 patients (5 men and 20 women with mean age of 56 +/-9 years) who met the FTD criteria proposed by the Lund and Manchester group. We analyzed their presenting symptoms and compulsive behaviors retrospectively.
RESULTS
The presenting symptoms were variable, including inappropriate judgement, loss of spontaneity, memory disturbance, personality change, apathy, repetitive movements, hypersexuality, and parsimony. Twenty-two out of the 25 patients (88%) showed compulsive behaviors. They included reading signboards, stereotypy of speech, ordering, hoarding, washing, checking, counting, singing, and wandering a fixed route.
CONCLUSIONS
Compulsive behaviors are commonly associated with FTD and thereby understanding of these symptoms together with presenting symptoms may help diagnose FTD early and minimize the misdiagnosis of FTD for Alzheimer's disease or other psychiatric illnesses.
