1. New study characterizes cognitive and anatomic differences in Alzheimer's disease gene carriers
   In the most comprehensive study to date, neurologists have clearly identified significant differences in the ways that Alzheimer's disease affects patients with and without the apolipoprotein E e4 gene, a known genetic risk factor for the neurodegenerative disease, using a combination of cognitive and neuroanatomic measures. The study found that this gene influences the way the disease manifests,
2. New neuroimaging analysis technique identifies impact of Alzheimer's disease gene in healthy brains
   Brain imaging can offer a window into risk for diseases such as Alzheimer's disease. A new study has demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD.
3. New brain scan better detects earliest signs of Alzheimer's disease in healthy people
   A new type of brain scan, called diffusion tensor imaging, appears to be better at detecting whether a person with memory loss might have brain changes of Alzheimer's disease, according to a new study.
4. Alzheimer's disease imaged long before symptoms appear
   Researchers were able to predict a brain's progression to Alzheimer's by measuring subtle changes in brain structure over time, changes that occur long before the symptoms of AD can be seen. With an earlier diagnosis, earlier intervention would be possible.
5. Predisposing factors for conversion of mild cognitive impairment to Alzheimer's disease identified
   Mild cognitive impairment (MCI) is often considered an early symptom of Alzheimer's disease. An analysis of genetic risk factors predisposing to MCI is critical for accessing individual predisposition and reliably evaluating the effectiveness of early treatment. In a groundbreaking study, researchers successfully used artificial neural networks to help understand the causal relation between multi
