Neuropsychiatric complications 3-4 years after stroke: a population-based study of fatigue, depression and cognition

Objectives
To study the prevalence of and interplay between common neuropsychiatric sequelae 3–4 years after onset of first-ever stroke—specifically post-stroke fatigue (PSF), post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI).

Design
Population-based cohort study.

Setting
Catchment area of a Swedish University Hospital.

Participants
We recruited individuals with first-ever ischaemic stroke or intracerebral haemorrhage in the initial cohort; 151 of these died prior to follow-up and 47 (12%) were lost to detailed follow-up. We followed up 202 individuals with median age: 72 (IQR 65–79), 40% female, either in clinic, via home visits or via telephone.

Primary and secondary outcome measures
Primary outcome measures included PSF (Fatigue Assessment Scale), PSD (Patient Health Questionnaire-9) and PSCI (Montreal Cognitive Assessment). Secondary outcome measures included dependency in activities of daily living (ADL; Barthel Index), health-related quality of life (HRQoL; Short-Form Questionnaire-36, EuroQoL-5D and Stroke Impact Scale) and stroke severity (National Institutes of Health Stroke Scale (NIHSS)).

Results
Significant PSF was present in 46/195 (24%), PSD in 21/191 (11%), and PSCI in 93/173 (54%) respondents. Among 169 participants with available data for all three domains, 100 (59%) had impairment in at least one domain. Participants with PSCI were older than those without (median: 75 vs 67 years; p
