About Alzheimers Disease

Alzheimer disease is a brain disorder. People lose the ability to think, reason, and remember. Symptoms can change from day to day. Over time the disease gets worse. Alzheimer dementia is when a person can no longer care for him or herself.

Brain cells stop working and begin to die. Why this happens is not clear. It could be a mix of:

People with Alzheimer disease have more things called tangles and plaques in their brains. These may block how the cells talk to each other. They are:

  • —pieces of a protein called tau fibers are twisted in the cells
  • —a protein called beta amyloid builds up between nerve cells

These changes often start where the brain stores memory. This damage may begin many years before a person has symptoms.
