Prevalence and associated behavioral symptoms of depression in mild cognitive impairment and dementia due to Alzheimer's disease.
Mild cognitive impairment (MCI) is a clinical concept that categorizes subjects who are in an intermediate cognitive state between normal aging and dementia. The aims of this study are to determine the prevalence of significant depressive symptoms in MCI and Alzheimer's disease (AD) patients and to characterize the behavior associated with significant depressive symptoms in MCI and AD patients. ⋯ Frontal lobe and behavioral symptoms are more prevalent and severe in MCI and AD patients with significant depressive symptoms as compared with patients without depressive symptoms.
