Until recently treatments for Alzheimer's disease did not exist. Currently, with the discovery of substances that can slow the course of Alzheimer's disease, and the discovery of the possibility of more radical treatment, the symptoms of Alzheimer's disease, Alzheimer's disease research are beginning to pay off. However, the nature of Alzheimer's disease is not well enough understood to expect that in the near future, it will learn to fully heal. We also consider the possibility of treating Alzheimer's disease with estrogen, ibuprofen, and dehydroepiandrosterone. In the future, experts in the field of neuroscience is likely to be able to transplant acetylcholine-producing cells in the brains of patients. This will almost certainly delay the development of Alzheimer's disease, but it is not clear whether it is fully cured.
