Conclusions 1 Population-Based Study 141 Events of First-Ever Stroke in Finnmark in 1998 Only 27% to Hospital within 3 Hours

Conclusions 2 Mean Age at Onset Men: 67 years, Women: 75 years Sickness Pension before the Stroke Men: 48%, Women: 42% Very High Risk Factors for Cardiovascular Disease

Conclusions 3 Severe Attacks 51% at Onset Complications, especially Urinary Tract Infections, are Numerous Some Complications are probably Underestimated Primary Outcome: 47% at Home, 9% further Rehabilitation, 31% Nursing Home, 12% Fatal

Conclusions 4 Outcome Worse in Women and in Higher Age Groups Fatality Rate at 12 Months: 24% Fatality Rate at 12 Months is related to Severity at Onset 50% of Survivors have Improved after 12 Months
