Alzheimer's Disease

What is Alzheimer's disease?

Alzheimer's disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects thinking and memory skills. If you have AD, it can impair your ability to reason or learn new skills until it becomes difficult to complete daily activities.

AD begins slowly over many years. It first involves the parts of the brain that control thought, memory, and language. It may be mistaken for normal memory changes with aging. However, AD is not a normal part of aging. The brain changes from the disease lead to symptoms that get worse over time.

People with AD may have trouble remembering recent events or the names of people they know. Behavior may vary from person to person and day to day. AD progresses in stages. Late-onset AD occurs in adults aged 65 and older, which is when most people develop the disease. Early-onset AD happens before age 65, which is not common.

Some symptoms of AD can include:

• Getting lost in familiar places
• Repeating the same question
• Not recognizing family members
• Having trouble speaking, reading, or writing
• Not taking care of yourself, such as not bathing or eating poorly

In AD, over time, symptoms get worse. Later on, people with AD may become anxious or aggressive or wander away from home. Eventually, they need total care. This can cause great stress for family members who must care for them.

Researchers don't fully understand what causes AD. Age is the biggest risk factor. Your risk is also higher if a family member has had the disease. Although people who develop Alzheimer's don't always have a history of the disease in their families.

Researchers believe the causes of AD may be a combination of age-related changes in the brain, along with genetic, health, and lifestyle factors. Some medical conditions that are associated with a higher risk of AD include:

• Hearing loss
• Depression
• Mild cognitive impairment
• Concussion or other traumatic brain injury (TBI)

A related problem, mild cognitive impairment (MCI), causes more memory problems than normal for people of the same age. Many, but not all, people with MCI will develop AD.

Some health conditions can cause memory loss or symptoms like AD. Talk with your health care provider if you're having noticeable changes in your memory. To determine if your symptoms are related to AD and not normal aging or another health condition, your provider may:

• Review your medical history and any medicines you're taking
• Conduct tests to check your memory, thinking, and problem-solving skills
• Ask about changes in behavior or personality
• Do tests to rule out any medical or mental health conditions
• Refer you to a provider that specializes in caring for older adults
• Recommend a neurologist, a doctor who specializes in treating diseases of the brain and nervous system

No treatment can stop the disease. However, some medicines may help keep symptoms from getting worse for a limited time.

You can't change some risk factors, like your age. But changing certain lifestyle factors may promote your brain health and help you live a healthier lifestyle overall. This can include to:

• Manage chronic health issues such as high blood pressure or hearing loss
• Get regular physical activity
• Eat a healthy diet
• Quit smoking (or don't start)
• Get enough sleep
• Develop strong social connections

Aneurysms

An aneurysm is a bulge or "ballooning" in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.

Most aneurysms occur in the aorta, the main artery that runs from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke.

Aneurysms can develop and become large before causing any symptoms. Often doctors can stop aneurysms from bursting if they find and treat them early. They use imaging tests to find aneurysms. Often aneurysms are found by chance during tests done for other reasons. Medicines and surgery are the two main treatments for aneurysms.

Angina

Angina is chest pain or discomfort you feel when there is not enough blood flow to your heart muscle. Your heart muscle needs the oxygen that the blood carries. Angina may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw, or back.

Angina is a symptom of coronary artery disease (CAD), the most common heart disease. CAD happens when a sticky substance called plaque builds up in the arteries that supply blood to the heart, reducing blood flow.

There are three types of angina:

• Stable angina is the most common type. It happens when the heart is working harder than usual. Stable angina has a regular pattern. Rest and medicines usually help.
• Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It does not go away with rest or medicine. It is a sign that you could have a heart attack soon.
• Variant angina is rare. It happens when you are resting. Medicines can help.

Not all chest pain or discomfort is angina. If you have chest pain, you should see your health care provider.

Antioxidants

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. They are also available as dietary supplements. Examples of antioxidants include:

• Beta-carotene
• Lutein
• Lycopene
• Selenium
• Vitamin A
• Vitamin C
• Vitamin E

Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet with lots of vegetables and fruits is healthy and lowers risks of certain diseases. But it isn't clear whether this is because of the antioxidants, something else in the foods, or other factors.

High-dose supplements of antioxidants may be linked to health risks in some cases. For example, high doses of beta-carotene may increase the risk of lung cancer in smokers. High doses of vitamin E may increase risks of prostate cancer and one type of stroke. Antioxidant supplements may also interact with some medicines. To minimize risk, tell your health care providers about any antioxidants you use.

Assistive Devices

What are assistive devices?

Assistive devices are tools, products, or equipment that can help you perform tasks and activities. They may help you move around, see, communicate, eat, or get dressed.

You may use various assistive devices if you:

• Have a disability or injury
• Have certain health conditions such as dementia, or if you've had a stroke
• Are an older adult

You might use an assistive device for a short time or long term. Others might use them throughout their lifespan.

Some assistive devices are high-tech tools, such as computers. Others are much simpler, like a "reacher," a tool that helps you grab an object you can't reach.

There are a variety of assistive devices or tools available that may be used to help you to:

• Communicate, see, or hear better
• Perform daily activities
• Move by using a wheelchair, walker, or another mobility device
• Cook or eat
• Dress or groom yourself
• Improve your memory or attention
• Be more active
• Participate in educational activities

Assistive devices may also be used to make changes to your physical environment so it is easier to move or care for yourself. This can include adding ramps or grab bars.
