Background And Objectives:
To determine the trajectory of depressive symptoms several years before and after incident stroke.
Methods:
We analyzed data from 10,797 participants from the English Longitudinal Study of Ageing without a history of stroke at baseline (wave 1). We matched participants with first-ever stroke during the 12-year follow-up (waves 2-7) to stroke-free individuals using propensity scores accounting for age, sex, education, ethnicity, and vascular risk factors. Trajectories of depressive symptoms before and after stroke were analyzed using multilevel models.
Results:
Among the 10,797 participants (mean age 64.6 ± 9.9 years, 54.8% women), we identified 425 individuals with incident stroke. At the assessment before stroke, these individuals demonstrated an increase in depressive symptoms when compared with matched controls. There was a further increase in depressive symptoms in stroke survivors after the acute event, which persisted for several years. Symptom-level analyses revealed that differences in depressive symptoms between stroke survivors and stroke-free controls before and after stroke were most pronounced for mood-related and fatigue-related symptoms.
Discussion:
Incident stroke is associated with long-term increases in depressive symptoms. A small part of this increase occurs in the years before stroke, perhaps indicating the incipient pathologic process. Particular attention should be paid to depressive symptoms in the long-term care of patients, and especially to fatigue-related symptoms.
