Abstract

Background/aims: Orthostatic hypotension (OH) and QTc prolongation have potentially important prognostic and therapeutic consequences but have rarely been studied in patients with mild dementia.

Methods: Patients with mild dementia were diagnosed according to consensus criteria after comprehensive standardized assessment. OH and QTc were assessed using standardized criteria.

Results: OH was significantly more common in the dementia than in the control group, and systolic drop was higher in those with dementia with Lewy bodies. There were no significant differences in QTc values between dementia and control subjects.

Conclusion: OH occurs even in patients with mild dementia, in particular in dementia with Lewy bodies. QTc was not prolonged in patients with mild dementia compared with normal controls.
