Changes can occur in the brain well before the onset of Alzheimer’s disease
[mis à jour le 20 April 2007 à 13h50]
Could there be new hope in the fight against Alzheimer’s disease? Three years on from an already promising study on the subject, a team of American researchers has revealed changes that occur in the structure of patients’ brains.
It appears that these can take place as much as several years before the appearance of the first signs of the disease. For five years, Charles Smith and his team at the University of Kentucky monitored 136 patients aged 65 and over at the start of the study. Twenty-three of them went on to develop Alzheimer’s disease.
During the course of the study, the researchers state that they “observed changes in the cerebral structure of these patients. And this was as much as four years before the diagnosis (of Alzheimer’s disease) was given”. They believe that this study will help in “better identifying those at risk of developing this illness”.
