MRI to Measure Treatment With Antibiotics in Alzheimer's Disease (DARAD-MRI)
To study the changes in brain structure and function using MRI scans in patients treated for Alzheimer's disease.
A pilot study of treating Alzheimer's disease with antibiotics showed some promise that this treatment could delay the deterioration of the mind with this disease. This study is being replicated on a larger scale, providing a more definitive answer to this question. In addition to looking at changes of the mind (through cognitive tests), we would like to use MRI scans in these patients before and after treatment to study the structural changes and the chemical changes in the brain. This would provide a non-invasive look at the bran processes that protect the brain from the effect of Alzheimer's as well as confirming that the disease has been modified with treatment.
The novel treatment of Alzheimer's with antibiotics has provided a potential breakthrough in the field. In addition to verifying changes in the brain, MRI scans can observe HOW this process could occur, thus opening doors to other new treatments for Alzheimer's and perhaps even cures.
