Discovering Alzheimer’s: The 4 Types That Can Affect Your Brain

Have you ever forgotten where you left your keys or walked into a room and forgot why you went there? It happens to everyone from time to time. But for some people, especially older adults, forgetting things can be a sign of a brain condition called Alzheimer’s disease. Alzheimer’s is a bit like a thief that sneaks into the brain, making it hard for people to remember things, think clearly, or take care of themselves. Today, we’re going to learn about the 4 different types of Alzheimer’s disease.

1. Early-Onset Alzheimer’s

Imagine a big, busy library. Now, imagine if someone started taking books away, and you couldn’t find what you were looking for. Early-onset Alzheimer’s is like this, but it starts when people are younger, usually between 30 and 60 years old. It’s like the library starts losing books way too early. This type is pretty rare, but it can run in families, so some people might be more likely to get it if their mom or dad had it.

2. Late-Onset Alzheimer’s

This is the most common type of Alzheimer’s. It usually starts after age 65. Think of it as a garden where the plants start to wilt and don’t grow as well anymore. In late-onset Alzheimer’s, parts of the brain start to change and don’t work as well as they used to, making it hard for people to remember new things, recognize family and friends, or solve problems.

3. Familial Alzheimer’s Disease (FAD)

Familial Alzheimer’s is a rare kind that’s passed down in families. If your family is one of the few that has FAD, it means you have a higher chance of getting Alzheimer’s at a younger age. It’s like inheriting a recipe from your family, but instead of getting a recipe for cookies, you get a higher chance of getting this disease.

4. Alzheimer’s Disease with Lewy Bodies

Imagine if sticky, gooey gum was stuck inside the library from our first example, messing up the books and shelves. Alzheimer’s with Lewy bodies has something similar happening in the brain. Lewy bodies are sticky clumps of protein that can build up in the brain, making it hard for the brain cells to talk to each other. This can cause problems with memory, thinking, and even movement.

What Does This Mean?

Knowing about these 4 types of Alzheimer’s helps doctors and scientists understand how to help people with the disease. It’s like knowing what kind of weed is growing in a garden so you can find the best way to remove it and help the garden thrive.

What Can You Do?

  • Stay Healthy: Eating healthy foods, staying active, and keeping your brain busy with puzzles or learning new things can help keep your brain strong.
  • Talk About It: If you’re worried about yourself or someone else, talking to a doctor can help. They can do tests to see what’s going on and help find the best way to take care of the problem.
  • Be Supportive: If you know someone with Alzheimer’s, being kind and patient can make a big difference in their day.


Alzheimer’s disease can be tricky and a little scary, but understanding the different types can help us find better ways to help people who have it. Just like each person is unique, the way Alzheimer’s affects people can be different too. By learning more and supporting each other, we can all help make the world a better place for people with Alzheimer’s.
