What is atrial fibrillation (AFib)?
Atrial fibrillation, also known as AFib or AF, is one of the most common types of arrhythmias. Arrhythmias are problems with the rate or rhythm of your heartbeat. They can cause your heart to beat too slowly, too fast, or in an irregular way.
If you have AFib, your heart beats irregularly and sometimes much faster than normal. Also, your heart's upper and lower chambers do not work together as they should. When this happens, the lower chambers do not fill completely or pump enough blood to your lungs and body. This can cause symptoms such as dizziness, fatigue, and a pounding heartbeat.
AFib may happen in brief episodes, or it may be a permanent condition. It's very important to treat it, since AFib can put you at risk for stroke and other heart conditions.
What causes atrial fibrillation (AFib)?AFib is most often caused by changes to the heart's tissue or the electrical signaling that helps the heartbeat. These changes can happen due to different conditions and factors, such as high blood pressure, coronary artery disease, congenital heart defects, infections, and aging. Sometimes the cause is unknown.
Who is more likely to develop atrial fibrillation (AFib)?Anyone can develop AFib, but there are certain things that raise your risk for it:
Some people who have AFib don't have any symptoms and don't know they have it. If you do have symptoms, you may only notice them once in a while. Or you may have symptoms that are more frequent. And in some cases, the symptoms might be severe. If you have heart disease, you are more likely to notice your symptoms. And those symptoms could get worse if your heart disease gets worse.
The symptoms of AFib can include:
If AFib is not treated, it can lead to serious health problems (complications) such as:
To help prevent these problems, it's important to contact your health care provider if you are having symptoms. If you do have AFib, the sooner you are diagnosed and treated, the better.

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body. Your nerves take in information from your senses and send it to the brain to be processed. Your brain and nerves also communicate to help you move and to control your body's functions.
When the brain is healthy, it works quickly and automatically. But when you have a brain disease, it may affect how well you can function and do your daily activities. Some common brain diseases include:
The symptoms of brain diseases vary widely, depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or therapies such as physical, occupational, and speech therapies, may cure the disease or improve the symptoms.
A caregiver gives care to someone who needs help taking care of themselves. The person who needs help may be a child, an adult, or an older adult. They may need help because of an injury or disability. Or they may have a chronic illness such as Alzheimer's disease or cancer.
Some caregivers are informal caregivers. They are usually family members or friends. Other caregivers are paid professionals. Caregivers may give care at home or in a hospital or other health care setting. Sometimes they are caregiving from a distance. The types of tasks that caregivers do may include:
Caregiving can be rewarding. It may help to strengthen connections to a loved one. You may feel fulfillment from helping someone else. But caregiving may also be stressful and sometimes even overwhelming. You may be "on call" for 24 hours a day. You may also be working outside the home and taking care of children. So you need to make sure that you are not ignoring your own needs. You have to take care of your own physical and mental health as well. Because when you feel better, you can take better care of your loved one. It will also be easier to focus on the rewards of caregiving.

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative brain disorder. Symptoms usually start around age 60. Memory problems, behavior changes, vision problems, and poor muscle coordination progress quickly to dementia, coma, and death. Most patients die within a year.
The three main categories of CJD are :
Cattle can get a disease related to CJD called bovine spongiform encephalopathy (BSE) or "mad cow disease." There is concern that people can get a variant of CJD from eating beef from an infected animal, but there is no direct proof to support this.
