Question

Quizplus · Accepted Answer

Alzheimer's disease causes degeneration and loss of brain cells, leading to shrinkage of the brain. This can be observed through brain imaging, such as MRI scans. The brain may also show physical markers, such as atrophy or shrinkage in specific regions, such as the hippocampus. The "creases" in the brain, known as gyri and sulci, may become more shallow due to the shrinkage.
