Both the cause and process of this nerve damage are still unknown (Senelick).
Damage to the brain begins about a decade before any symptoms appear. The damage initially takes place in the hippocampus, the section of the brain that forms memories (“Alzheimer’s Disease Fact Sheet”). Alzheimer’s is a progressive disease, meaning that it worsens over time. After a while, it causes hallucinations, false memories, and the loss of the ability to form coherent sentences (Check 14).
