What Causes ‘Alzheimer’s Disease’ and How Does It Affect Memory?

Imagine your brain is like a big library full of books, each book is a memory. Alzheimer's disease makes the librarian forget where the books are, and eventually, the books get lost or broken. That’s why people with Alzheimer’s lose their memories over time.

Alzheimer’s happens when something starts blocking messages between brain cells. These blockages are like sticky clumps that grow bigger and bigger in the brain, making it harder to remember things.

The more these clumps grow, the fewer connections there are between brain cells, just like a library with fewer shelves and books.
