Understanding Alzheimer’s Dementia Quizlet
What is Alzheimer’s Dementia?
Alzheimer’s disease is a progressive neurological disorder that causes the brain to shrink and brain cells to die. It is the most common cause of dementia, accounting for 60-80% of all dementia cases. Alzheimer’s disease is characterized by a gradual decline in cognitive function, including memory loss, confusion, and difficulty with communication, problem-solving, and judgment.
