Alzheimer's Basics, Part 1

Alzheimer's Changes the Whole Brain

Alzheimer's disease leads to nerve cell death and tissue loss throughout the brain. Over time, the brain shrinks dramatically, affecting nearly all its functions.

These images show:

Scientists see the terrible effects of Alzheimer's disease when they look at brain tissue under the microscope. Scientists are not absolutely sure what causes cell death and tissue loss in the Alzheimer's brain, but  plaques and tangles that develop are prime suspects.  Alzheimer's tissue has many fewer nerve cells and synapses than a healthy brain.
