title: Poststroke fatigue and depression are related to mortality in young adults: a cohort study.
abstract: OBJECTIVE
  To investigate the relationship between poststroke fatigue and depression and subsequent mortality in young ischaemic stroke patients in a population-based study.
  
  
  METHODS
  A prospective cohort study.
  
  
  METHODS
  All surviving young ischaemic stroke patients living in Hordaland County.
  
  
  METHODS
  Young ischaemic stroke patients aged 15-50 years at the time of the stroke were invited to a follow-up on an average 6 years after the index stroke. Psychosocial factors and risk factors were registered. Fatigue was self-assessed by the Fatigue Severity Scale (FSS). Depression was measured by Montgomery-Åsberg Depression Rating Scale (MADRS).
  
  
  METHODS
  No intervention was performed.
  
  
  METHODS
  Mortality on follow-up.
  
  
  RESULTS
  In total, 190 patients were included. The mean age on follow-up was 48 years and subsequent follow-up period was 12 years. Cox regression analysis showed that mortality was associated with FSS score (p=0.005) after adjusting for age (p=0.06) and sex (p=0.19). Cox regression analysis showed that mortality was associated with MADRS score (p=0.006) after adjusting for age (p=0.10) and sex (p=0.11).
  
  
  CONCLUSIONS
  Both fatigue and depression are associated with long-term mortality in young adults with ischaemic stroke. Depression may be linked to higher mortality because of psychosocial factors and unhealthy lifestyles whereas the link between fatigue and mortality is broader including connection to diabetes mellitus, myocardial infarction and psychosocial factors.
