Gut Bacteria May Play a Role in Alzheimer’s Disease
Latest research from Lund University in Sweden, reveals that intestinal bacteria can lead to the development of Alzheimer’s Disease. The findings of the study could lead too new ways of prevention and treatment of the disease. Scientists and researchers studied healthy mice and those affected with Alzheimer’s. The research revealed that the mice with the disease have a different composition of gut bacteria than those that were unaffected. The researchers also studied lacking bacteria and found that those mice had a smaller amount of beta-amyloid plaque- lumps that form at the nerve fibers in cases of Alzheimer's disease. To further clarify the link between Alzheimer’s Disease and intestinal bacteria, researchers injected the bacteria into mice without any. This trial found that the mice that were injected, developed more beta-amyloid plaque. These revelations mean that scientists can now look into ways to prevent, treat and delay the onset of Alzheimer’s Disease.

Deep brain stimulation studies in Alzheimer's disease pose ethical challenges
There are studies of deep brain stimulation for the treatment of Alzheimer's disease. But there has been ethical challenges with this population regarding the decision making of the post study treatments. This treatment was approved for the treatment of movement and neuropsychiatric disorders, such as Parkinson's disease, DBS is a surgical procedure involving the implantation of a microstimulator that sends electrical impulses to specific targets in the brain. Which could potentially help with memory loss and improving the brain.

Mouse Model Points to Potential New Treatment for Alzheimer's Disease
There was a study done where a certain enzyme was reversed, so it would it decline. This enzyme has been show to be elevated in those individual with Alzheimer's Disease. Mice with an Alzheimer's Disease phenotype were used for this experiment. There were memory tests conducted on the mice. The scientist waited till the mice were a year old, and then they began the experiment. The scientist worked "by helping nerve cells digest toxic proteins that might otherwise cause cell death". After the treatment the levels of Aβ and insoluble tau proteins were reduced.
