Alzheimer's disease is a progressive disorder that causes brain cells to waste away degenerate and die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that disrupts a person's ability to function independently. The early signs of the disease may be forgetting recent events or conversations. As the disease progresses, a person with Alzheimer's disease will develop severe memory impairment and lose the ability to carry out everyday tasks.

Current Alzheimer's disease medications may temporarily improve symptoms or slow the rate of decline. These treatments can sometimes help people with Alzheimer's disease maximize function and maintain independence for a time. Different programs and services can help support people with Alzheimer's disease and their caregivers. There is no treatment that cures Alzheimer's disease or alters the disease process in the brain.

In advanced stages of the disease, complications from severe loss of brain function — such as dehydration, malnutrition or infection — result in death. Memory loss is the key symptom of Alzheimer's disease. An early sign of the disease is usually difficulty remembering recent alzheimers disease video or conversations. As the disease progresses, memory impairments worsen and other symptoms develop.

At first, a person with Alzheimer's disease may be aware of having difficulty with remembering things and organizing thoughts. A family member or friend may be more likely to alzheimers disease video how the symptoms worsen. Everyone has alzheimers disease video memory lapses. It's normal to lose track of where you put your keys or forget the name of an acquaintance. But the memory loss associated with Alzheimer's disease persists and worsens, affecting the ability to function at work or at home.

Alzheimer's disease causes difficulty concentrating and thinking, especially alzheimers disease video abstract concepts such as numbers.

Multitasking is especially difficult, and it may be challenging to manage finances, balance checkbooks and pay bills on time. These difficulties may progress fonts para tatuagem escrita music an inability to recognize and famatech radmin s with numbers.

The ability to make reasonable decisions and judgments in everyday situations will decline. For example, a person may make poor or uncharacteristic choices in social alzheimers disease video or wear clothes that are inappropriate for the weather. It may be more difficult to respond effectively to everyday problems, such as food burning on the stove or unexpected driving situations.

Once-routine activities that require sequential steps, such as planning and cooking a meal or playing a favorite game, become a struggle as the disease progresses. Eventually, people with advanced Alzheimer's may forget how to perform basic tasks such as dressing and bathing.

Brain changes that occur in Alzheimer's disease can affect moods and behaviors. Problems may include the following:. Many important skills are preserved for longer periods even while symptoms worsen. Preserved skills may include reading or listening to books, telling stories and reminiscing, singing, listening to music, dancing, drawing, or doing crafts. These skills may be preserved longer because they are controlled by parts of the brain affected later in alzheimers disease video course alzheimers disease video the disease.

A number of conditions, including treatable conditions, can result in memory loss or other dementia symptoms. If you are concerned about your memory or other thinking skills, talk to your doctor for a thorough assessment and diagnosis. If you are concerned about thinking skills you observe in a family member or friend, talk about your concerns and ask about going together to a doctor's appointment.

Scientists believe that for most people, Alzheimer's disease is caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time. Less than 1 percent of the alzheimers disease video, Alzheimer's is caused by specific genetic changes that virtually guarantee a person will develop the disease. These rare occurrences usually result in disease onset in middle age.

The exact causes of Alzheimer's disease aren't fully understood, but at its core are problems with brain proteins that fail to function normally, disrupt the work of brain cells neurons and unleash a series of toxic events. Neurons are damaged, lose connections to each other and eventually die. The damage most often alzheimers disease video in the region of alzheimers disease video brain that controls memory, but the process begins years before the first symptoms.

The loss iis 7.5 for windows 7 neurons spreads in a somewhat predictable pattern to other regions of the brains. By the late stage of the disease, the brain has shrunk significantly. Increasing age is the greatest known risk factor for Alzheimer's disease.

Alzheimer's is not a part of alzheimers disease video aging, but as you grow older the likelihood of developing Alzheimer's disease increases. One study, for example, found alzheimers disease video annually there were two new diagnoses per 1, people ages 65 to 74, 11 new diagnoses per 1, people ages 75 to 84, and 37 new diagnoses per 1, people age 85 and older.

Your risk of developing Alzheimer's is somewhat higher if a first-degree relative — your parent or sibling — has the disease.

Most genetic mechanisms of Alzheimer's among families remain largely unexplained, and the genetic factors are likely complex. A variation of the gene, APOE e4, increases the risk alzheimers disease video Alzheimer's disease, but not everyone with this variation of the gene develops the disease.

Scientists have identified rare changes mutations in three genes that virtually guarantee a person who inherits one of them will develop Alzheimer's. But these mutations account for less than 1 percent of people with Alzheimer's disease. Many people with Down syndrome develop Alzheimer's disease. This is likely related to having three copies of chromosome 21 — and subsequently three copies of the gene for the protein that leads to the creation of beta-amyloid. Signs and symptoms of Alzheimer's tend to appear 10 to 20 years earlier in people with Down syndrome than they do for the general population.

There appears to be little difference in risk between alzheimers disease video and women, but, overall, there are more women with the disease because they generally live longer than men. Mild cognitive impairment MCI is a decline in memory or other thinking skills that is greater than what would be expected for a person's age, but the decline doesn't prevent a person from functioning in social or work environments.

People who have MCI have a significant risk of developing dementia. When the primary MCI deficit is memory, the condition is more likely to progress to dementia due to Alzheimer's disease.

A diagnosis of MCI enables the person to focus on healthy lifestyle changes, develop strategies to compensate for memory loss and schedule regular doctor appointments to monitor symptoms. Research has shown that poor sleep patterns, such as difficulty falling asleep or staying asleep, are associated with an increased risk of Alzheimer's disease. Research has shown that the same risk factors associated with heart disease may also increase the risk of Alzheimer's disease.

These include:. These factors can all be modified. Therefore, changing lifestyle habits can to some degree alter your risk. For example, regular exercise and a healthy low-fat diet rich in fruits and vegetables are associated with a decreased risk of developing Alzheimer's disease. Studies have found an association between lifelong involvement in mentally and socially stimulating activities and a reduced risk of Alzheimer's disease.

Low education levels — less than a high school education — appear to be a risk factor for Alzheimer's disease. Memory and language loss, impaired judgment, and other cognitive changes caused by Alzheimer's can complicate treatment for other health conditions. A person with Alzheimer's disease may not be able to:. As Alzheimer's disease progresses to alzheimers disease video last stages, brain changes begin to affect physical functions, such as swallowing, balance, and bowel and bladder control.

These effects can increase vulnerability to additional health problems such as:. Alzheimer's disease is not a preventable condition. However, a number of lifestyle risk factors for Alzheimer's can be modified. Evidence suggests that changes in diet, exercise and habits — steps to reduce the alzheimers disease video of cardiovascular disease — may also lower your risk of developing Alzheimer's disease and other disorders that cause dementia.

Heart-healthy lifestyle choices that may reduce the risk of Alzheimer's include the following:. Studies have shown that preserved thinking skills later in life and a reduced risk of Alzheimer's disease are associated with participating in social events, reading, dancing, playing board games, creating art, playing an instrument, alzheimers disease video other activities that require mental and social engagement.

alzheimers disease video

In healthy people, all sensations, movements, thoughts, memories, and feelings are the result of signals that pass through billions of shania twain mp3 songs cells, or neurons, in the brain. Neurons constantly communicate with each other through electrical charges that travel down axons, causing the release of chemicals across tiny gaps to neighboring neurons.

Other cells in the brain, such as astrocytes and microglia, clear away debris and help alzheimers disease video neurons healthy. These changes may occur years, even decades, before the first signs of dementia. Researchers believe that this process involves two proteins called beta-amyloid and tau, which somehow become toxic to the brain. It appears that abnormal tau accumulates, eventually forming tangles inside neurons.

And beta-amyloid clumps into plaques, which slowly build up between neurons. As the alzheimers disease video of amyloid reaches a tipping point, there is a rapid spread of tau throughout the brain. Other changes that affect the brain may also play a role over time. Eventually, neurons lose their ability to communicate. As neurons die, the brain shrinks, beginning in the hippocampus, a part alzheimers disease video the brain important to learning and memory.

People may begin to experience memory loss, impaired decision-making, and language problems. Achieving a deeper understanding of the molecular alzheimers disease video cellular mechanisms—and how they may interact—is vital to the development of effective therapies. Much progress has been made in identifying various underlying factors. Advances in brain imaging allow us to see the course of plaques and tangles in the living brain. Blood and fluid biomarkers are providing insights about when the disease starts and how it progresses.

More is also known about the genetic underpinnings of the disease and how they can affect particular biological pathways. Research is moving quickly, ever closer to the alzheimers disease video when we can delay or even prevent the devastation of dementia.
