Have you ever forgotten where you put your keys or the name of a new friend you just made? It happens to everyone, but Alzheimer’s disease is a lot more than just forgetting things once in a while. It’s a sickness that affects the brain and makes it hard for people, especially older ones, to remember things, think clearly, and take care of themselves.

ToggleWhat is Alzheimer’s Disease?
Alzheimer’s disease is a special kind of disease that mostly happens to older people. It makes it hard for them to remember things, like what they did yesterday or even the names of their family and friends. It’s not just about getting a little forgetful, as we all do sometimes. This disease makes it harder and harder for them to think and remember as time goes by.
How Does Alzheimer’s Happen?
Alzheimer’s disease is a bit like a puzzle that doctors and scientists are still trying to solve. They know it has to do with problems in the brain, but they’re still figuring out why it happens to some people and not others. Let’s dive a bit deeper into what goes wrong in the brain when someone has Alzheimer’s.
The Brain: Our Control Center
First, think of your brain as the control center for your body. It’s like the most advanced computer ever made, handling everything from your thoughts and memories to your movements and senses. In Alzheimer’s disease, this control center starts having problems.
Plaques and Tangles
There are two main troublemakers in Alzheimer’s: plaques and tangles. These aren’t the kinds of plaques you win for a sports game or the tangles you get in your hair. They’re something that shouldn’t be in your brain.
- Plaques: These are clumps of a protein called beta-amyloid. Imagine if you’re playing a team game, and you need to pass a ball quickly between your teammates. Now, imagine if there were sticky goo all over the ball. That’s what these plaques are like. They stick to the brain cells and make it hard for them to communicate. This communication is super important for everything your brain does, especially for making memories.
- Tangles: These are twisted fibers of a protein called tau. Normally, tau helps with the structure of brain cells – kind of like the beams in a building. But in Alzheimer’s, these tau proteins get all twisted up. Think of it like a railroad track that’s gotten so twisted that the trains can’t run. This messes up the way nutrients and other important stuff move inside the brain cells.
The Brain’s Changing Structure
As these plaques and tangles build up, they cause the brain cells to work less efficiently, and eventually, these cells die. The brain actually starts to shrink in size because of this. Areas of the brain that are responsible for memory and thinking skills are often the first to be affected. That’s why one of the first signs of Alzheimer’s is usually trouble remembering things.
A Complex Puzzle
Scientists also believe that genes (the parts of our DNA that we inherit from our parents), lifestyle, and environmental factors might play a role in who gets Alzheimer’s. It’s like a complex recipe with many ingredients, and not everyone’s recipe is the same.
Who Gets Alzheimer’s?
Alzheimer’s disease can seem a bit mysterious in terms of who it affects. Let’s break down what we know about who is more likely to get this disease:
- Older Adults: The biggest risk factor for Alzheimer’s is age. Most people who get Alzheimer’s are 65 or older. As you get older, the risk gets higher. It’s like how things wear out in an old car; sometimes, parts of the brain start to wear out, too.
- Early-onset Alzheimer’s: This is a less common type. It can happen to people even in their 40s or 50s. It’s like the disease gets a head start in some people, and scientists are still trying to understand why. Here are a few things to know about early-onset Alzheimer’s:
It’s quite rare, affecting only about 5% of all people with Alzheimer’s.
Genetics (the traits we inherit from our parents) might play a bigger role here. Some people have certain changes in their genes that make them more likely to get this
Type of Alzheimer’s.
- Family History: Your chances of getting Alzheimer’s are a bit higher if a close family member, like a parent or sibling, has had the disease. It’s not a sure thing, but it’s like if your family has a history of being really good at a sport, you might have a higher chance of being good at it, too.
- Gender: Women seem to be more likely than men to develop Alzheimer’s. Researchers think this might be partly because women generally live longer than men, and age is a big risk factor.
- Lifestyle and Heart Health: Things that are bad for your heart are also bad for your brain. High blood pressure, high cholesterol, and obesity can increase the risk of Alzheimer’s. Living a healthy lifestyle with good food and exercise might lower the risk.
- Head Injuries: People who have had serious head injuries may have a higher risk of Alzheimer’s later in life. It’s like if you damage a machine, it might not work as well years later.
Symptoms of Alzheimer’s
Alzheimer’s disease affects people in different ways, but there are some common symptoms that many people experience. Think of these symptoms as warning signs that something might be wrong with the brain’s functioning. Here’s a list of some of the symptoms people with Alzheimer’s might have:
Memory Loss: This is usually the most noticeable symptom. People with Alzheimer’s might:
- Forget important dates or events.
- Ask for the same information over and over.
- Rely heavily on memory aids (like reminder notes or electronic devices) or family members for things they used to handle on their own.
Difficulty Planning or Solving Problems: Some people may experience changes in their ability to follow a plan or work with numbers. They might:
- Have trouble following a familiar recipe or keeping track of monthly bills.
- Find it hard to concentrate and take much longer to do things than before.
- Trouble Completing Familiar Tasks: Daily tasks can become a challenge. This could include:
- Having problems driving to a familiar location.
- Forgetting the rules of a favorite game.
- Having difficulty managing a budget at work.
Confusion with Time or Place: People with Alzheimer’s can lose track of dates, seasons, and the passage of time. They might:
- Have trouble understanding something if it is not happening immediately.
- Forget where they are or how they got there.
- Trouble with Visual Images and Spatial Relationships: For some, having vision problems is a sign of Alzheimer’s. This can lead to difficulty with:
- Reading.
- Judging distance.
- Determining color or contrast may cause problems with driving.
- New Problems with Words in Speaking or Writing: People with Alzheimer’s may:
- Have trouble following or joining a conversation.
- Stop in the middle of a conversation and have no idea how to continue.
- Struggle with vocabulary, have trouble naming a familiar object, or use the wrong name (e.g., calling a “watch” a “hand-clock”).
- Misplacing Things and Losing the Ability to Retrace Steps: A person with Alzheimer’s may:
- Put things in unusual places.
- Lose things and be unable to go back over their steps to find them again.
- Sometimes, they may accuse others of stealing, especially as the disease progresses.
- Decreased or Poor Judgment: This might include:
- Making bad decisions with money.
- Paying less attention to grooming or keeping themselves clean.
- Withdrawal from Work or Social Activities: A person with Alzheimer’s may:
- Start to remove themselves from hobbies, social activities, work projects, or sports.
- Avoid social situations because of the changes they have experienced.
- Changes in Mood and Personality: The mood and personalities of people with Alzheimer’s can change. They can become:
- Confused.
- Suspicious.
- Depressed.
- Fearful.
- Anxious.
- Easily upset at home, at work, with friends, or in places where they are out of their comfort zone.
Diagnosing Alzheimer’s Disease
Figuring out if someone has Alzheimer’s disease is not as straightforward. There isn’t just one test that can tell for sure. Instead, neurologists use a bunch of different methods to get a clear picture of what’s going on in the person’s brain.
Talking About Medical History
- Asking Questions: The doctor will ask the person and their family about any changes in behavior, memory, and thinking skills. This is like gathering clues to understand what’s been happening.
- Looking at Family History: The doctor will also ask if there are other family members who have had Alzheimer’s or other brain-related issues, as this can sometimes run in families.
Mental Status Testing
- Memory Tests: The doctor will do some simple tests to check the person’s memory, problem-solving skills, attention, counting skills, and language abilities.
Questionnaires: Sometimes, the doctor might use special questionnaires that are designed to measure the person’s mental skills.
Physical and Neurological Exams
- General Checkup: The doctor will do a physical exam to see if there are any other health problems that could be causing the symptoms.
- Neurological Function Tests: This involves checking the person’s balance, reflexes, muscle tone and strength, sense of sight and hearing, coordination, and speech. These tests help the doctor see if there’s a problem in the brain or nervous system.
Brain Imaging
- CT or MRI Scans: These are like special X-rays that let doctors see inside the brain. They can show if there are any changes in the brain’s structure that might be due to Alzheimer’s.
- PET Scans: In some cases, doctors might use a PET scan to look for plaques in the brain, which are one of the hallmarks of Alzheimer’s.
Lab Tests - Blood Tests: These can help rule out other causes of memory loss and confusion, like thyroid problems or vitamin deficiencies.
Putting the Pieces Together
After collecting all this information, the neurologist will put together all the pieces of the puzzle. If most of the evidence points towards Alzheimer’s and other causes have been ruled out, the doctor can make a diagnosis. It’s important to know that even with all these tests, sometimes it can be hard to be 100% sure if someone has Alzheimer’s, especially in the early stages.
What Happens Next?
If the neurologist thinks it’s Alzheimer’s, they will talk about the best ways to manage the disease. This might include medication, lifestyle changes, and getting support from family, friends, and caregivers. Remember, an early diagnosis can be really helpful in managing the symptoms and planning for the future.
Living with Alzheimer’s: A Friendly Guide
Living with Alzheimer’s disease can be challenging, both for the person who has it and for their family and friends. But with patience, understanding, and a few adjustments, life can still be enjoyable and fulfilling. Here’s a friendly guide on how to make the best of living with Alzheimer’s:
For Those with Alzheimer’s
- Stay Positive: Remember, you’re still you, even with Alzheimer’s. Focus on what you can do and enjoy, and don’t be too hard on yourself when things are difficult.
