Dementia is a group of conditions that affect memory, thinking, and behavior. It happens when brain cells become damaged or die, making it harder for a person to remember things, solve problems, or communicate. Dementia is not a normal part of aging, though it becomes more common as people get older. If you or someone you care for is experiencing memory loss or confusion, understanding what dementia is and how doctors identify it can help you prepare for conversations with healthcare providers and know what to expect.

The articles here explain the different types of dementia, how doctors test for and diagnose the condition, what changes to expect as it progresses, and how to support someone living with dementia. You'll also find information about treatments that may slow symptoms, ways to manage daily life, and resources for caregivers.
