Researchers Believe Anxiety Can Contribute To Alzheimer’s Development
anxiety and alzheimer'sIn a recent study entitled “Anxiety symptoms in amnestic mild cognitive impairment are associated with medial temporal atrophy and predict conversion to Alzheimer’s disease” the authors report on how people with mild cognitive impairment have higher risk of developing Alzheimer's, especially if they suffer from anxiety. The study was published in the online issue of The American Journal of Geriatric Psychiatry. The study, led by researchers at the Baycrest Health Sciences' Rotman Research Institute, shows that individuals exhibiting mild cognitive impairment (MCI) have an increased risk to develop Alzheimer's, with mild anxiety being associated with a 33% increased risk for Alzheimer's, while severe anxiety is associated with a 135% increase. The authors found that anxiety symptoms in MCI patients were associated with an increased decline in cognitive functions and higher rates of atrophy in the brain region responsible for memory formation, as well as the medial temporal lobe regions within the brain.
