What is Alzheimer's disease?

Alzheimer's refers to a neurodegenerative disease characterized by progressive impairment of ability that makes it hard to remember things, think clearly, learn new things, and keep things in order. It worsens with time and makes one fail to do simple, daily tasks. Most dementia cases are due to AD.

Alzheimer's can worsen with time. It is hypothesized to begin a decade or more prior to the appearance of symptoms. The disease predominantly affects those fifty and older.

Who does Alzheimer's disease affect?

The vast majority of people with Alzheimer's are over age 65. Your risk of developing Alzheimer's increases with your age after age 65.

However, some people develop early-onset Alzheimer's disease. This is when people begin to develop Alzheimer's disease symptoms in their 40s or 50s. Early-onset Alzheimer's disease is unusual. Less than 10% of AD cases are early-onset.

What is Alzheimer's disease before it gets worse?

When researchers study Alzheimer's disease, most providers only discuss the preclinical stage. Patients at the preclinical stage of AD typically do not experience any symptoms.

But their brains are changing in some ways. This stage may last for many years or even decades. People in this stage usually don't have Alzheimer's yet because they're still working well.

Now, through brain imaging tests, amyloid buildup in the brain can be detected before symptoms arise. Amyloid is a protein that causes interference in the way your brain communicates with itself.

What are the symptoms and signs of Alzheimer's disease?

The signs of Alzheimer's disease get worse over time, which is called a progressive disease. One of the most important signs is memory loss, which usually shows up first. Symptoms appear gradually over months or years.

If symptoms persist for hours or days, this could be a stroke, and the person needs to go to a doctor immediately.

These are some of the signs of Alzheimer's disease:

• Memory loss is when a person has trouble remembering things and taking in new knowledge. This can cause:
• Repeating questions or conversations
• Misplacing objects
• Forgetting about appointments or events
• Getting lost or wandering

• Cognitive impairments: A person might lose their judgment, reason less, and cannot accomplish heavy tasks. This could mean:
• Less knowledge of dangers or safety
• Problems with money or the ability to pay bills
• Problems with decision-making
• Problems completing tasks that require multi-step actions, such as dressing

• Issues with recognition: Even when a person is able to see things, they cannot identify faces or objects very well or make use of simple tools.
• Difficulty with spatial awareness: The person would have difficulty keeping his or her balance and may have frequent falls or spills. He or she may even have difficulty dressing by putting clothes on the wrong way.
• Problems with speaking, reading, or writing: A person might struggle to recall common words, or they may commit more errors in speaking, spelling, or writing.
• Changes in mood or personality: A person may feel and behave differently, such as:

• Getting angry, upset, or worried more often than usual
• Losing interest in or drive to do things they once found enjoyable
• Having less feeling for others
• Compulsive, obsessive, or other socially unacceptable behavior

What causes Alzheimer's disease?

Alzheimer's disease is caused by an abnormal buildup of proteins in the brain. The cells in the brain die when these proteins (amyloid protein and tau protein) build up.

There are more than 100 billion nerve cells and other cells in the brain. All the contact that is needed to do things like think, learn, remember, and plan is done by nerve cells working together.

Researchers hypothesize that in Alzheimer's disease; amyloid protein accumulates in brain cells and creates plaques, which are larger agglomerations. Another type of protein called tau has filaments that twist and compact. These plaques and tangles disrupt the interaction between nerve cells, inhibiting them from performing their task.

The signs of Alzheimer's disease are caused by nerve cells slowly dying over time. Nerve cell death starts in one part of the brain and then moves to other parts. This usually happens in the hippocampus that controls memory.

Scientists do not still know what exactly causes these proteins to build up despite long researches. To their best guess, early-onset Alzheimer's is caused by some genetic mutation. Late-onset Alzheimer's may probably be the result of many complex changes in the brain that can take place over years. Probably, genetic and environmental as well as lifestyle factors combine to contribute towards the cause.

How do you know if somebody has Alzheimer's disease?

No single test determines whether the person has Alzheimer's or not. The doctor asks about the symptoms, experiences, and past health of the person if they suspects that they have this condition.

The friends or family members are sometimes requested to provide their opinion because they notice the signs of dementia sooner than the individual themselves.

In addition to those, the doctor may carry out or request the following tests:

• Cognitive and memory tests for assessing the person's ability to think and remember
• Blood or urine tests
• Neurological function tests to test their balance, senses, and reflexes
• Genetic testing
• MRI or CT scan of brain

In some instances, genetic testing may be required because the signs of dementia can be associated with a genetic disease, such as Huntington's disease. There are also genes, such as the APOE gene, that are associated with Alzheimer's disease.

Early testing for relevant genes could show how likely it is that someone has or will get the problem.

How is Alzheimer's disease cared for?

There is no recognized treatment that can cure Alzheimer's. There is no known cure that can reverse the death of brain cells.

However, treatments are available that could relieve the symptoms and enhance quality of life. Emerging treatments might even slow the progression of disease.

They include:

Medicines to alleviate symptoms

Drugs called cholinesterase inhibitors reduce the cognitive symptoms of Alzheimer's disease, such as the loss of memory, disorientation, disturbed thought patterns, and poor judgment. They facilitate the communication across the brain and slow down the progression of these changes.

These are the FDA-approved drugs for Alzheimer's disease in the category of cholinesterase inhibitors:

• Galantamine (razadyne) formild to moderate stages
• Rivastigmine (exelon) inmild to moderate stages
• Donepezil (aricept) isgiven for all stages

Another drug, memantine (Namenda), is approved by the FDA for the treatment of moderate and severe Alzheimer's disease. Memantine and donepezil are also available in one combination called Namzaric.

Doctors may prescribe antidepressants or antipsychotics when mood or mental health conditions seem to change.

Medicines that alter diseases

There are now drugs that can delay the progression of Alzheimer's. These include:

• Lecanemab (Leqembi), which in a phase 3 clinical trial slowed further growth by 25%
• Kisunla, a drug called donanemab that slowed cognitive decline by 32% in a review of earlier studies
• Aducanemab (Aduhelm), which hasn't had much of an impact on brain function and is still being tested

All the medicines given for Alzheimer's disease have associated risks. People can discuss these with their doctor in more detail.

Other therapies

These are some other treatments to help alleviate symptoms:

• Making a safe, familiar living space
• removing things that could cause pain or harm
• keeping routine
• Getting exposure to sunlight and sleeping at a regular bedtime to improve sleep.
• Doing daily physical exercises may slow Alzheimer's worsens

How can I reduce my risk of getting Alzheimer's disease?

There is no known way to prevent Alzheimer's disease. Most experts say that the best way to protect your brain's health is to live a healthy, busy life.

What can I expect if a loved one has Alzheimer's disease?

It's crucial to note that Alzheimer's disease affects every individual differently. It is not easy to know what will happen to your loved one. The best way to prepare is to talk to doctors and nurses who study and treat Alzheimer's disease and dementia.

As the disease worsens, your loved one may require a team of people to take care of their needs.

How long do Alzheimer's disease patients live?

The future for patients with Alzheimer's disease usually is not too good. The disease moves in varied ways among various people. On the contrary, most individuals above 65 years old who are diagnosed with AD die within four to eight years. Some people can still be living up to 20 years after the first symptoms appear.

Among the various causes of deaths, some are as follows:

• Coughing up
• Not having enough food and water.
• Some other infections.

When should I go to the doctor or nurse?

If you or someone you care about is having trouble remembering things or thinking straight, you should see a doctor. They can figure out if the problems are caused by Alzheimer’s disease or something else.

See your medical team often if you or a loved one has been diagnosed with Alzheimer's disease to make sure your care plan is working for you and to see how the disease is getting worse.

What should I talk to the doctor about?

Those of you whose loved one has Alzheimer's disease may find it helpful to ask their medical team the following:

• In what ways does Alzheimer's disease usually get worse?
• What symptoms and signs should I look out for?
• What kinds of treatments are there for Alzheimer's disease?
• Which do you think is best?
• Are there any scientific trials?
• Where can I find the best care for my family member?
• What do I need to do to make sure their home is safe and nice?
• What kinds of programs and support groups are in my area?
• Do I have a chance of getting Alzheimer's disease?
• Does it run in your family?
