Washington: Alzheimer`s could actually sabotage the working of several of the brain`s networks, says a study.Beau Ances, assistant professor of neurology, Washington University School of Medicine in St. Louis, who led the study said: "Communications within and between networks are disrupted, but it doesn`t happen all at once.""There`s even one network that has a momentary surge of improved connections before it starts dropping again. "That`s the salience network, which helps you determine what in your environment you need to pay attention to," added Ances, The Journal of Neuroscience reported.Ances and colleagues analyzed brain scans of 559 subjects. Some of these subjects were cognitively normal, while others were in the early stages of very mild to mild Alzheimer`s disease.
