This information describes the symptoms, diagnosis, and treatment of dementia.
Dementia is the loss of brain functions, such as memory, thinking, and reasoning, that interferes with a person’s daily functions.
Dementia itself isn’t a disease. It’s a term used to describe a group of symptoms caused by various diseases or conditions. It usually develops slowly over time and is most often seen in older adults. However, it’s not a normal part of aging. Some common symptoms may include:
- Trouble remembering recent events.
- Getting lost in familiar places.
- Difficulty with tasks, such as balancing a checkbook, paying bills, or planning activities.
- Problems with language, such as trouble finding the right word.
- Changes in their personality or behavior
Most adults experience some form of mild forgetfulness. This usually doesn’t point to a serious memory problem, but if symptoms get worse or they get in the way of your daily activities, you may need to see a doctor.
If you’re worried about your loved one’s forgetfulness, speak with their doctor so they can get help right away.

Your doctor will review your medical history, perform a physical exam, and order blood tests. They will evaluate your memory, problem solving, counting, and language skills. Your doctor may also order imaging of the brain, such as computed tomography (CT) scans or magnetic resonance imaging (MRI), to gather more information.Back to top
Treatment for Dementia
While there isn’t a cure for dementia at this time, there are some medications that may improve symptoms temporarily. Your doctor will discuss your treatment options with you.
You may also benefit from getting enough sleep, following routines (such as following a schedule for meal times and bedtime), and continuing social activities.Back to top
