Major and minor depression in Alzheimer's disease: prevalence and impact
Lyketsos CG, Steele C, Baker L, Galik E, Kopunek S, Steinberg M, Warren A.. The Journal of neuropsychiatry and clinical neurosciences, 1997-01-01
Topic: Amyloid, tau and blood-test diagnosis
One hundred nine outpatients with Alzheimer's disease (AD) were neuropsychiatrically evaluated and rated on standardized measures of depression, activities of daily living (ADL), nonmood behavioral disturbance, and burdensome events such as serious wandering, falls, and accidents. Distribution of depression scores revealed three patient groups: very few depressive symptoms (51%), minor depression (27%), and major depression (22%). Major depression was associated with substantially greater impairment in ADL, worse nonmood behavioral disturbance (such as aggression), and more frequent serious wandering, even after adjusting for severity of dementia or comorbid health problems. Minor depression was also associated with nonmood behavioral disturbance and wandering. The authors conclude that both major and minor depression are common in AD and produce considerable mood and nonmood morbidity affecting both patients and caregivers. Efforts are warranted to identify and treat depression in AD.
Key findings
- Distribution of depression scores revealed three patient groups: very few depressive symptoms (51%), minor depression (27%), and major depression (22%).
- Major depression was associated with substantially greater impairment in ADL, worse nonmood behavioral disturbance (such as aggression), and more frequent serious wandering, even after adjusting for severity of dementia or comorbid health problems.
- Minor depression was also associated with nonmood behavioral disturbance and wandering.
- The authors conclude that both major and minor depression are common in AD and produce considerable mood and nonmood morbidity affecting both patients and caregivers.

How this study scored 41/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 24 of the 58 points we could judge it on, which is 41 out of 100.
