Alzheimers
Alzheimer’s is one of the most incurable neurodegenerative diseases out there. And it remains one of those scientific mysteries scientists have not yet figured out. Alzheimer’s causes dementia, which in turn affects people’s memory and motor skills with a decline until death. Even though scientists have been studying Alzheimer’s for decades, they’ve still been unable to find a highly effective treatment, despite everything they know about the disease. But one thing is for certain, is that scientists don’t know what truly causes the disease.

There are many theories and speculations, but they haven’t found a solidified reason. Vox reports that “for years, the prevailing theory has been that Alzheimer’s is caused by pile-ups of proteins called amyloids, which effectively create plaques in the brain. But drugs that help clear amyloids from the brain don’t seem to work very well in combating the disease. Some scientists think Alzheimer’s researchers have been too focused on this one theory, at the expense of studying other potential causes, like viral infections.” Despite all the research, they still have not come up with an answer. All we can do is hope that one day, scientists will figure out the cause and develop a cure for this heartbreaking disease (Vox).
