This volume focuses on the stroke risk factors that are amenable to modification and describes ongoing strategies for their amelioration. It emphasizes primary prevention of risk factors because intervention before a stroke risk factor appears is clinically likely to yield the highest benefits, but it also recognizes secondary prevention measures as important in reducing the chance of a stroke. A strength of this book is its reliance on well-founded, scientifically derived evidence interpreted by clinically experienced stroke experts. The authors assess the state of our current knowledge of successful stroke prevention measures while pointing out areas where there is a need to develop new and better prevention techniques.
