Prioritizing problem features in Korean patients with senile dementia for implementation of monitoring technologies.

The purpose of this study was to investigate the central problem features of Korean patients with senile dementia and to prioritize the features according to risk to the patient with a view to the implementation of remote monitoring technologies. Twenty central problem features were extracted using factorial analysis. The frequency of violent language and confabulation, gathering, and repetition was significantly greater in female than in male patients with senile dementia. All central features, with the exception of abnormal sexual behavior and audiovisual deficits, differed in frequency between the normal elderly and the senile dementia patients and between patients with dementias of different severity. Judgment disorder was the greatest differentiating factor between the normal elderly and the patients with senile dementia. For dementia severity, memory disorder was the greatest differentiating factor of severe versus mild dementia. When risk to the patient was analyzed, problems of perception were identified as the problem features of highest priority.
