An understanding of the alzheimers disease

Neuroimaging Damage to parts of the brain involved in memory, such as the hippocampus, can sometimes be seen on brain scans before symptoms of AD occur.

Ginkgo biloba Early studies suggested that extracts from the leaves of the ginkgo biloba tree may help treat AD symptoms. They are known as cholinesterase inhibitors. However, clinical trials have not shown that it can slow the progression of already diagnosed AD.

Although patients can achieve comfort, dignity, and independence for longer periods, and caregiving An understanding of the alzheimers disease be less difficult, it is important to remember that none of these medications stops the disease itself.

Researchers are making progress, but for now there is no cure for the disease that takes away memory and, ultimately, life itself. Doctors use several tools to diagnose "probable" AD, including: There is increasing evidence that some of the risk factors for heart disease and stroke, such as high blood pressure, high cholesterol, and low levels of the vitamin folate, may also increase the risk of AD.

However, the reduced risk disappeared after 18 months, and by the end of the study, the probability of the two groups progressing to AD was the same. Symptoms that begin suddenly may be a sign of this kind of dementia. There is no evidence yet that ginkgo biloba will cure or prevent AD, but scientists now are trying to find out in a clinical trial whether it can delay cognitive decline or prevent dementia in older people.

To Find Out More Visit www. Treating these behavioral symptoms often comforts patients and eases their care.

Patients may be able to maintain certain daily functions a little longer, such as going to the bathroom independently for several more months, benefiting themselves and their caregivers. The number of sufferers doubles every five years beyond age Family history is another factor.

Inflammation Evidence shows that inflammation in the brain may contribute to AD damage. Additional studies are investigating whether antioxidants—vitamins E and C—can, too.

Where they occur determines the seriousness of the problem and the nature of the symptoms. And one study found that women over the age of 65 who used estrogen with a progestin were at greater risk of dementia, including AD, and that older women using only estrogen could also increase their chance of developing dementia.

The disease usually begins after age 60, and risk goes up with age. Younger people may get the disease, but that is much less common.

As many as five million Americans suffer from AD. In addition to genetics, scientists are studying the influence of education, diet, and environment.

Scientists believe that Namenda works by regulating glutamate, another important brain chemical that, when produced in excessive amounts, may lead to brain cell death.

Genetics may play a role in many cases. Some studies have suggested that drugs such as nonsteroidal antiinflammatory drugs NSAIDs might help slow AD, but clinical trials thus far have not demonstrated a benefit from these drugs. Compared with those on the placebo, the study group taking donepezil was found to be at reduced risk of progressing to AD for the first 18 months of the three year study.

Five prescription drugs currently are approved by the U. Also, some medicines may help control sleeplessness, agitation, wandering, anxiety, and depression. But this can be done only by examining the brain after a person dies. Although scientists are learning more every day, they still do not know what causes AD, and there is no cure.

Because Namenda works very differently from cholinesterase inhibitors, the two types of drugs can be prescribed in combination.Alzheimer's is the most common cause of dementia, a general term for memory loss and other cognitive abilities serious enough to interfere with daily life.

Alzheimer's disease accounts for 60 percent to 80 percent of dementia cases.

Recognize the stages and symptoms of Alzheimer's disease

However, a lot is happening on the frontlines of Alzheimer’s research and our understanding of the disease, as well as hope for an eventual cure grow exponentially.

The symptoms of Alzheimer's disease often come on slowly. It might start when someone has trouble recalling things that just happened or putting thoughts into words. But over time, the problems. Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks.

In most people with the disease—those with the late-onset type —symptoms first appear in their mids. NIH MedlinePlus the Magazine, Understanding Alzheimer's.

Sometimes these tests show that the symptoms are being caused by thyroid problems, drug reactions, depression, brain tumors, or blood vessel disease in the brain, conditions that can cause Alzheimer's-like symptoms but are treatable. As Alzheimer's and other dementias progress, behaviors change—as does your role as caregiver.

While changes in behavior can be challenging, we have resources to help you through each stage of .
