Who is affected by atherosclerosis risk not only stroke but also to memory problems. was announced by the American Academy of Neurology, which anticipates the results of a study that in these days will be presented during an annual convention held in Philadelphia. A very important result, which emphasizes – says Brajesh Kumar Lal, an expert from the School of Medicine of the University of Maryland, Baltimore. “the importance of ascertaining the state of the memory and reasoning in people with a narrowing of the carotid artery . ”

Until now, the diagnosis and treatment of obstruction of the carotid arteries the two large blood vessels that lie on either side of the neck has had as its main objective the prevention of stroke, “as goes on to explain Lal was the only danger was thought to be induced in the patient by this obstruction. “Instead, this new study has opened my eyes to a more risk meeting in which you can go getting sick of atherosclerosis, which is nothing but the hardening of arterial walls: the danger of a memory impairment.


To this result was achieved by testing specific learning abilities and memory of 67 patient with the asymptomatic carotid artery stenosis. This consists in a narrowing of the internal diameter of the artery that carries blood to the head (in the subjects examined the amplitude of the carotid artery was reduced by 50 per cent) due to the presence of atherosclerosis plaques, due to the accumulation of thickenings fat or a proliferation of connective tissue.

Once this is done, the condition of these people was compared with that of 60 other individuals with cardiovascular risk factors such as diabetes, high blood pressure, high cholesterol and coronary heart disease but not with carotid steno sis. Final result of the study: the presence of atherosclerosis impairs the memory of those affected, significantly reducing the performance in memory tests and reasoning. “S and these results are confirmed in larger studies – announces the scholar Lal will have significant implications in terms of new targets for treatments. ”
