What is Dementia?
Dementia is a group of symptoms that affect a person's memory, thinking, and social abilities. It's not a single disease, but a term that describes a wide range of symptoms associated with a decline in memory or other thinking skills. This decline is severe enough to reduce a person's ability to perform everyday activities.
When someone has dementia, their brain cells are damaged and can't communicate with each other properly. This affects their thinking, behavior, and feelings. People with dementia may have trouble remembering things, solving problems, or controlling their emotions. They might also experience changes in personality and have difficulty with tasks they used to do easily.
Types of Dementia. Each type can affect different parts of the brain and cause different symptoms.
Alzheimer's Disease (the most common)
Frontotemporal Dementia
Lewy Body Dementia
Vascular Dementia
Dementia usually gets worse over time. In the early stages, someone might just be a bit forgetful. But as it progresses, they might have trouble recognizing family members, managing their finances, or taking care of themselves. This can be very challenging for both the person with dementia and their loved ones.

Trend
In the United States, about 6.7 million people aged 65 and older have Alzheimer's dementia in 2023. This number has increased from about 5.8 million in 2020.
It's projected that by 2028, about 7.6 million Americans aged 65 and older may have Alzheimer's dementia if current trends continue.
History
The term "dementia" has been used for centuries, but our understanding of it has changed a lot. In ancient times, people thought memory loss in old age was just a normal part of getting older. In the early 1900s, Dr. Alois Alzheimer described the first case of what we now call Alzheimer's disease. This was a big step in understanding dementia. Over the 20th century, doctors learned more about different types of dementia and how they affect the brain. In recent decades, there's been a lot of research to find better ways to diagnose and treat dementia, and to understand what causes it.
