Researchers conducting recent studies believe that the use of testosterone supplements may help prevent Alzheimer’s disease. Their research is showing that supplementation may be useful for both men and women. Alzheimer’s disease is usually found in elderly individuals and is a common form of dementia. The most common symptom is memory loss, but other symptoms include confusion, mood swings and trouble speaking coherently. There is currently no cure for Alzheimer’s disease. Both sexes have testosterone in their systems, but as men age and as women become postmenopausal their levels of this hormone decreases. It is a known fact that Alzheimer’s disease is characterized by plaques inside the brain that have been formed by the deposition of b-amyloid peptides. Scientists and researchers are studying and discovering that testosterone has been found to decrease the secretion of b-amyloid peptides by as much as 30 – 45 percent. That is a significant decrease and results such as these could very well help lead to an ultimate cure and end of this terrible disease. More studies are being conducted and possible side effects such as prostate or endometrial cancer caused by using testosterone supplements to prevent Alzheimer’s disease are one of the major concerns being looked into.
