Alzheimer’s disease, it slowly takes things away from the person without giving anything back. Right now there is no cure and at best we can slow the progression in some cases. Time is always a factor and no two cases are the same. However, new treatments are in the works and a new study has revealed that a single dose of an immunotherapy reverses memory problems in an animal model of Alzheimer’s disease.
The blood-brain barrier, the thorn in the side of medicine. It makes using drugs directed for the brain ineffective at best and unusable at worst. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. This barrier means that currently 98% of therapeutic molecules are also unable to cross to the brain. However, researchers now say magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain.
