What usually causes alzheimer's disease?

Nobody knows: In most cases, it is not clear what are the causes of alzheimer's disease. In some cases, the cause is an abnormal gene but that is true in only about 5% of people with alzheimer's disease.

Unknown: That is a billion or trillion dollar question. We know that when people have Alzheimer's parts of their brains die off in a certain order and cause specific symptoms. A myeloid plaques and tau tangles are found in people's brains. But we still don't know exactly what triggers the disease.
