A daily dose of acetylsalicylic acid equivalent to a fourth of an aspirin may slow the decline in intellectual capacity among elderly individuals with high cardiovascular risk. This is shown in a study by Sahlgrenska Academy, University of Gothenburg, Sweden. Researchers at Sahlgrenska Academy, University of Gothenburg, over a five year period studied how intellectual capacity changes among 681 elderly women (70 to 92 years) with heightened risk of suffering from a heart attack, vascular spasm or stroke.
