What are the main symptoms of Alzheimer's disease?

trouble remembering things. because you can't remember things, it leads to other symptoms like depression and anger. it's like dementia but worse.

Explanation:

proteins known as beta - amyloid form into large clumps called tangles and plaques. they get in the way of normal brain function, and starts to kill healthy cells. this usually starts to happen in the part of the brain where memories start to form. from there, they progressively start to spread in your brain. that is why you can't remember things. the part of your brain that forms memories probably took the most damage.
