Physical activity before stroke, small vessel disease and cognitive decline after stroke

Hypothesis

Higher level of PA before acute ischemic stroke (AIS) is associated with decreased risk of cognitive decline after stroke independently of stroke severity and cSVD burden.

Data

  • Physical Activity Scale in the Elderly (PASE) questionnaire
  • Modified Rankin Scale (mRS)
  • Level of education
  • Informant Questionnaire on Cognitive Decline in the Elderly, short version (IQCODE)
  • Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Scandinavian version
  • Wellbeing and depressive symptoms
  • Cerebral Small vessel disease burden (cSVD score)
