Is it true that only older people can get Alzheimer's?

Alzheimer's can strike people in their 30s, 40s and even 50s. This is called younger-onset Alzheimer's. It is estimated that there are as many as 5.4 million people living with Alzheimer’s disease in the United States. This includes 5.2 million people age 65 and over and 200,000 people under age 65 with younger-onset Alzheimer’s disease.
