Could Alzheimer's Dementia Be Caused by a Virus?
I've addressed some of this research in previous posts:
Today, we will take a peek at one of the more compelling theories about the cause of Alzheimer's -- it may well be due to an infection. Meaning exposure to certain parasites, bacteria, or viruses, particularly those that tend to inhabit the central nervous system, could bring on the disease. Even if you don't find Alzheimer's that compelling, if infectious agents contribute to its pathology, then you have to open your mind to the idea that many neurodegenerative processes could be due to (or accelerated by) infection. Neurodegenerative diseases include many neurological illnesses, but also depression, bipolar disorder, schizophrenia, autism, and some other psychiatric illness.
