Background• It is the progressive mental deterioration that can occur in middle
or old age, due to generalized degeneration of the brain.
• It causes a steady loss of memory, speech, thinking, and carrying on daily activities.
• As a person becomes older the risk for developing Alzheimer’s increases.
• Annual cost can be over $50,000
• Affects over 26.6 million people worldwide
Symptoms•Memory loss
• confused about time and place
• changes in personality and mood
• trouble speaking and accomplishing tasks
7 Stages1. No impairment
