  1. aHigher values indicating more severe stroke symptoms. NIHSS at baseline assessed at day 1 of admittance to hospital
  2. bLower values indicating poorer global cognitive function. MoCA assessment at baseline was performed either at discharge or 7 days after admittance for patients with longer hospital stay
  3. cInfections, seizures, neurological progression and falls registered during hospitalization
  4. dValues < 3 indication no to very mild cognitive decline
